"U of T's forestry school faces the axe"

"U of T's forestry school faces the axe" - The Globe and Mail.

The article is from April 1st. (apologies it slipped by me).

"Student Eric Jacobsen said “We do a lot more social and integrative approaches to forestry ...and it’s also less of an industry-focused program.”"

And a choice place to learn about urban forestry.

I'm dumbfounded.

Why compromise the capacity of a faculty that already exists?

And I can't imagine a worse time to do it.

To state the obvious: currently this city and cities across this country are dealing with massive urban reforestation commitments (variations of planting X# trees, &/or achieving X% canopy cover, by Y date). It seems to me that our best urban foresters are still struggling to figure out what those targets even mean, or should mean. Will it mean x% canopy cover that will last 30 or a 130 years? Which species: indigenous, native, exotic, invasive, GM'd, mass produced cheap clones? Beyond carbon sequestration, which ecological services should be integrated into those targets? And then, how to pull together the political will and the required resources to make make intelligent policies actually happen on the ground? This current surge of tree planting funding is a sudden and massive experiment, and a responsibility and opportunity happening on our watch. And so are its impacts on a changing mix of urban forestry stewardship orgs, private and public sector urban forestry industries and its professions. All of this at time when we know our urban forests are in ecological crises, e.g. degradation from historic and changing land uses, the challenge of reducing urban sprawl so we can retain ecological heritage and functions, the need to remediate post-industrial contamination in soil and groundwater, invasive species and climate change.

An intelligent continuing commitment to develop the skills and capacity necessary to understand, conserve, restore and engineer beneficial ecological function of our forests (urban and otherwis) can only help. Which leads me to wonder, if not now, when would be a more relevant and necessary time or opportunity for us /our universities, to support and study forestry?

Carolinian zone native plant seed collectors & growers: this one's about *you*

The Role of Native Plant Seed Collectors and Growers in Protecting Floral Diversity
by David N. Morris
A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Geography Waterloo, Ontario, Canada, 2010. Supervisor: Prof. Stephen D. Murphy.

"...The planting of native species is a common strategy for the conservation of biodiversity ...there has been very little research done about the diversity within plantings by non-state actors. This research was undertaken to address this knowledge gap by studying the provenances of planted rare species and the activities of those who collect and grow these plants. This research was undertaken in the Carolinian zone of southern Ontario, a region with a large number of rare plant species and a large human population."
To the author, David: awesome thesis topic. Thanks for the insight, the recommendations, and for developing research that can be credibly cited. And thanks for an interesting read too: it's the closest I've seen yet to a southern Ontario version of Susan Orlean's "The Orchid Thief" ;)

*****

Southern Ontario stewards, gardeners and seed collectors can find practical and ethical advice here:

1. The Society For Ecological Restoration
- Ontario Chapter updated their Growers Guidelines and Buyers Guidelines w/in the past year.
(BTW: SERO also widely publicized these guidelines to their partners and across academic, private, public and enthusiast newsletters. They also inventoried commercial native plant growers across the province -- & not just those who sell restoration quality plants-- and then sent each one of them these guidelines, along with an invitation to contact SERO for further information or assistance. Thank Megan and the Steve's! Not bad for an entirely volunteer effort. Did I mention SERO could use some volunteers, Board Members, and someone w/ desktop publishing skills for the new guide? It's a rare opportunity really: the current active members have so much experience they're a fascinating privilege to volunteer alongside).

2. Forest Gene Conservation Association. The FGCA site answers a lot of questions about how to ethically seed collect and purchase our native woodies from a ecological literate, biodiversity & Species-at-Risk conservation perspective. Also, along w/ partner organizations, they've delivered several publicly accessible "Certified Seed Collector" workshops in the past few years throughout south, central and eastern Ontario.
***
Also related: in the past few years, when it comes to gardens, I've become a conservative proponent of seed collecting from only common native plants (even in urban Toronto that's at least 200+ species that adapt well in gardens). And I advise folks to report rare species to their local Conservation Authority or OMNR for their records, and otherwise leaving the rare species to their habitats and the pros: the Species-at-Risk recovery teams, conservation biologists and ecologists, and ecological restorationists -- all of whom I've only seen welcome participation from locally knowledgeable people.

But I had to get past my initial ignorance. While it's easy to find lists of Ontario's and its Ecoregions Species-at-Risk, it's very difficult for most people to access local conservation "L ranks" for plant species-at-risk. I've thought about this last point often, and I still don't understand why our local Conservation Authorities don't make those L ranks publicly accessible. I don't see what risks it would pose. But I do see the benefits.

Also, even among some of the better non-profits orgs who buy, plant, grow and sell natives, most aren't even aware that several popular native plant species were added to the Ontario Endangered Species Act w/in the past couple of years, although Graham Buck (Nith River Native Plant & Seeds owner and OMNR staff) did provide public workshops. And so I still see these species commonly collected, sold and purchased, by folks who aren't even aware of the status of these species, let alone the required permits for exemption from our provincial SAR legislation (e.g. for growers who use these seeds to supply eco-restoration and conservation practitioners). In those cases, I believe I have better luck by starting up a conversation about it and then following up by sending folks information (hey, most of us are ecological illiterate and trying to learn) than I would if I tried to play some imaginary hard-headed 'plant nazi' (Do you know I've never met one? I don't think they actually exist. I think it's a mythical derisive term created by people who are trying to appease their own conscience and insecurities). But make no mistake, I want our Species-at-Risk to survive in their habitats for another generation, and a few more after that.

Speaking of First Nations Arboriculture...

"As mankind continued to chip his chert for stone warfare at the end of the Stone Age, he became very interested in the nut as food. It is thought that the movement of a nut called hazel or Corylus across the world was due almost entirely to mankind's fondess for its flavour. Indeed in North America, the mesolithic practice of the grand savannah design came into being primarily as a nut pasture to amplify game. This was a design centered around the open solar exposure of a nut-bearing canopy, whose wild grass pasture was flash-fired in April and November. This ashing of the soil produced fertilizer, pest management and increased herd capacity all rolled into one. The real gold came later on in the fall as crops of nuts. These were called pekan, or nut, throughout the length and breadth of the continent by an aboriginal culture that knew what it was doing and why it was doing it."

Spooky Hallowe'en Tree

Baker's Sugar Bush, Vaughn.

All I really want for Hallowe'en is a Shagbark Hickory

I love the Hallowe'en front porch displays, especially the gourds. But at this time of year what I really want in my yard is a Shagbark Hickory Carya Obvata.

I don't have any good pics of mature Shagbarks myself, but here is a perfect one - do you see what I mean?

What an unapologetically feral looking tree. In an urban residential front yard, it would stick out like a defiant middle finger among (and towards) any manicured properties around it. I'd like to meet the person who would plant this as a high wildlife value specimen tree in their front yard.

And, yes, a perfect tree for Hallowe'en. As William Cullina wrote, the bark's sheets "...hang there forlornly, so the whole tree takes on a shaggy, uneven aspect ... the bare trees seem alive and almost sinister on a wet foggy day."

Intrigued? This article is worth a read: Shagbark Hickory (Carya ovata) Ontario Arborist, May/June 2010, Michael Richardson, B.Sc.F., Consulting Arborist. Couple of highlights:

Shagbark Hickory as bat habitat:

"The bats use the trees as roost and maternal sites and apparently not only use the peeling sheets to hide under but finds that shagbarks provide excellent thermal regulation. In Ontario, species such as the little brown bat (Myotis lucifugus), the silver-haired bat (Lasionycteris noctivagans), and likely the big brown bat (Eptesicus fuscus) are found using live shagbarks. It seems clear that in forests and urban situations, the loss of dead trees with sloughing bark has lead to a decline in bats using natural roost sites. Shagbark hickories provide excellent roost sites as the bark begins to shed at 10+ years and can continue to provide outstanding habitat for two centuries or more."
Shagbark Hickory and First Nations arboriculture:
"First Nation people may have practiced arboriculture, and this, along with their agricultural practices, helps to explain the range and density of shagbark hickory. By managing individual trees and entire landscapes, these peoples have had a great influence on forests in eastern North America. First Nations were once considered to be in harmony with nature, but now many scientists believe that they were in fact a “keystone” factor in ecosystem development. [here's a wikipedia definition of 'keystone species']

Throughout the world, traditional cultures farmed various fruit and mast trees, which made survival easier than that of the constantly moving hunters and gathers. This has been termed balanoculture. In eastern North America, shade-tolerant forests (maple-beech) could not meet the dietary requirements of First Nations. The manipulation of forests – and in fact entire landscapes – using deliberately set fires was a method to help assure sufficient food stuffs.

The use of fire, planting, tree girdling and forest thinning allowed creation of “orchards” of hickory and other mast crops. Hickory nuts were one of the main foodstuffs for many First Nations throughout eastern North America. Nuts and acorns are calorie packed and could be stored. The sweet nuts of shagbark hickory seemed to be particularly favoured and are amongst the highest caloric ratings of mast crops.

In eastern North America, the distribution of early succession forests and hickory, oak and chestnut appear to be strongly predicted by First Nation occupation. This relationship is so strong that estimates of occupation is a better predictor of oak, hickory and chestnut than a number of topographic and soil variables."
Here in Toronto, I know Steve Smith / Urban Forest Associates plants them in the Don Valley (a young grove of them in Windfields Park for one). I'm already excited to see them when they mature. I especially want to walk among their silhouettes some dusky October eve.

oh, the curious wee life

Wee life along Alvar Road, Carden Plains ON

This pic is full of wonders for me: i don't know the mushroom (but i love the way he looks like maybe he's curious about me too) or the grass or the lichen w/ the stove pipes. But what intrigues me the most is the 4th species in the photo: the one which absurdly looks like some kind of 3 inch tall rubbery kelp, but w/ prickly-spiny leaf edges. I feel ridiculous even describing it like a sea or tidal zone plant, because it's growing on and between limestone pavement at an inland alvar, but, yeah, those are the only kinds of plants I've seen resembling it.

Anyone have a clue?

Early spring in the GTA

"The wonder is that we can see these trees, and not wonder more."
-Ralph Waldo Emerson.

In corollary, every year while i anticipate and watch the arrival of spring's first plants, I wonder how I can perennially wonder so much.

Sightings Sunday and Monday April 11th and 12th:

In the woods and forested ravines:
  • carpets - not in bloom but leafed out: trout lily, wild leek, Virginia waterleaf
  • colonies - wild ginger and bloodroot in bloom, Mayapples leafing out
  • small clumps and scatterings - red trilliums in early bloom; squirrel corn (a Dicentra similar to Dutchmen's breeches) is leafed out looking like muted silvery highlights. Visible still leafing-out scatterings: false solomon's seal, red and white baneberry, downy yellow violet, big leaved asters and zig-zag goldenrod (those latter two won't even bloom until late summer, so i find it interesting to know they begin their leaves so early / come out to catch such early sunlight)
  • Red elderberry aka Red-berried elder Sambucus racemosa ssp. pubens (S. pubens) flowers just arriving.
What strikes me about the above assortment is how much they collectively resemble what i call my "tough guy" list: these are pretty much the same plants i recommend to new woodland and urban shade gardeners because they're so hard-core / reliable, even in new soils. They're also the same plants folks use not only to attempt to resist invasives (like DSV, garlic mustard), but to strategic replant in areas after invasive removal. Vive la Résistance! Tip for dry shade gardeners: I'm having good luck w/ our local bush honeysuckle Diervilla lonicera shrubs in dry clay next to a silver maple in part building shade that only gets some summer sun (i distinguish "building shade" from natural forest shade because it's neither dappled or sunny-before-the-trees-leaf-out).

Along the Lake Ontario shoreline and bluffs:

Buffalo berry (aka Soapberry) Shepherdia canadensis
on a coastal shoreline at the toe of Scarborough bluffs
. It's also a
suggested indigenous plant for a Green Roofs in Toronto (TRCA)
  • in bloom - buffalo berry/soapberry (note: in conventional horticulture, you'll see varieties of it called Russet Buffalo berry. BTW: Silver buffalo berry Shepherdia argentea is NOT native here), wild strawberry and pussy willows (yup, i just wrote "pussy willows" like i am 10 years old. i already own a well-field-worn copy of the ROM's Shrubs of Ontario, and as singularly indispensable and illuminating as it has been for my native shrub IDs, it's only given me less confidence in my ability to distinguish Salix species)
  • silverweed leafing out
  • horsetails sporing
  • exotic Coltstfoot in bloom. no surprise: it's always the 1st early flower i see along the lake. it guides into warmer shoreline pockets and exposed steep sloped till and clay niches. and always makes me wonder what used to fill those microclimates / niches?
*
Spring has decidedly arrived here in the early half of April this year. And so far the only visible frost damage I've come across was on the leaves of an exposed edge colony of wild ginger = I'm starting to *relax* about it all ;)

I also notice that the squirrels have officially naturalized Scillia into every garden bed i tend. i don't quite know what to make of that. i mean, i don't have native Spring Beauty plants to replace them with. Squirrels. those little tricksters. Gardening: to be at the mercy of the designs of squirrels. I trust the ants so much more than the squirrels...

*
In Eastern Ontario, The Marvelous in Nature was marking the 1st blooms too. Love her blog. And whenever she writes in plantae I want to have her babies. ;)

*
UPDATE Thursday April 15th:

Red maples have been in bloom for a few days, in yellow and red flowers (so are the invasive Norway maples: those greenish-yellow flowers on so many street trees right now. Soon they'll leaf out earlier and more densely than our native maples, their dense shade depriving our spring woodland ephemerals and understorey shrubs of sunlight).

Just noticed Poplar catkins in bloom this morning along the lakeshore: including cottonwoods, balsam poplars & trembling aspen.

Anticipating:
  • Should also be able to find our locally uncommon Spicebush Lindera Benzoin in bloom right now in High Park. I plan on buying a few this year for my woodland garden beds.
  • In GTA naturalized areas such as the Brick Works, Fragrant Sumach Rhus aromatica shrubs and Redbud Cercis canadensis (small trees with pink-purple legume flowers) are both grown out of range (native to southern Ontario, but not to GTA), and should be in bloom soon if not already.

Hepatica, early spring

Sharp-lobed hepatica
on the paler and pinker side of hepatica's
white -> periwinkle blue hues

phe·nol·o·gy: "phenology has been principally concerned with the dates of first occurrence of biological events in their annual cycle"

Here in my garden near the lake in Toronto, Sharp-lobed Hepatica began blooming on April 2nd this year. Wild Ginger blooms began the same day too. The crimson petal tips of my Red Trillium have also been showing, but haven't opened yet. Expecting bloodroot to open tomorrow. Just about all the spring woodland ephemerals in my garden are either crowned or leafing out.

It's an early spring this year.

But at this point anything could happen: from +23c last week to -1 and snowflakes last night. The possibility of repeated freeze-thaws makes me edgy. Makes me anxious for the plants and insects ... craziness, like imagining bundling them in tailor-fitted knitted wool cozies :), or covering the newly germinated fragile green (hepatica? wild blue phlox? downy-yellow violet? The local ants have their own garden design plans i'm not privy to) in cloches (but not going to do that either: maybe i'm an field grown purist? i know i like my plants to be road-tested / grown in the realities of my yard's climate, weather). So, instead, I'm keeping all the leaves and mulch on the ground as is (besides, putting those in yard waste bags to be hauled away is effectively like removing your soil, its biota and plant nutrition from your land) and even leaving up last autumn's hollow stems for any insects still finding refuge or developing in there, and, mentally crossing-my-fingers against any killer frosts.

How to find local southern Ontario stewardship groups and events

Most of the events I post are related to stewardship and native plant events in the GTA (and a few obvious happy-places of mine in Southwestern Ontario too). But truth is, in the GTA, let alone Southern Ontario, there are a lot more excellent local stewardship and native plant gardening events to discover.


TIP: if you're looking for your local stewardship groups and events, try drilling through these links:

Bud Burst: Silver Maples

Silver Maple female flowers (left) with pollen on them
from male flowers (right)


Silver Maples Acer saccharinum can have both sexes on the same tree. The red flowers in the foreground are female. The "pom-pom" looking flowers on the right are male and loaded with pollen. If you look close (or click on the pic) you can see the male's yellow pollen grains have already been wind blown onto the female flowers.

Most of my street's trees are mature Silver Maples. Just sitting on my front porch, I can see at least a dozen 100-year-old-big Silver Maples currently in bloom, so it's looking very "birds do it, bees do it, the flowers and the trees do it" randy-in-the-skies to me right now.

They're not the only mating game going on this early in the season: I saw a female squirrel eating the Silver Maples' flower buds. She needs their early nutrition: she already has her whitish patchy "jacket" on. It's not mange, it's motherhood. She's already mated and plucked fur from her upper body to insulate her and her brood's nest.

Silver Maple are early bloomers. Before the Red Maples. Although the two bloom periods do overlap and naturally cross to become what's called Swamp Maple aka Freeman Maple Acer x fremmanii. They're trying them now up the street from here, say they're less brittle. I'm thinking about getting one for my neighbourhood park.

Here in southern Ontario, our earliest native blooms open in this order:

1. Skunk Cabbage
2. Silver Maples
3. Harbingers-of-Spring Erigenia bulbosa (rare)
4. Spring Beauty
5. then a blur of hepatica (see comments), ginger, trout lily, toothwort, bloodroot, dwarf ginseng and foamflower. I still can't figure out their order because at exactly "spring woodland ephemeral" time, I'm usually happily hiking all over southern Ontario between places where the bloom times might be different by five days.

I'm grateful to whoever chose to plant my street with Silver Maples. I know they were a popular street tree all over the city ("were" = now some of the urban forestry and hydro guys complain that they overmature too fast, are too brittle, drop limbs, too much debris), but they're especially appropriate to this area, and what it was: the backwater of the former Ashbridges Bay, Lake Ontario. Despite the area since being landfilled, these trees are appropriate to what this area's buried soils and gullies and hydrology and high water table still are. "Silver maple appears as a dominant species only in streamside communities or on the fringes of lakes or backwaters of streams. Occasionally it is found in swamps, gullies, and small depressions of slow drainage. Though it generally cannot compete with other species in upland environments, silver maple seedlings are adapted to survive long periods of inundation in bottom lands, where flooding is one of the factors that determine the makeup of individual stands..." Read the source of that quote here, it's a good one. Just how water-edge adapted are Silver Maples? Check out this pic (above right) from U of Wisconsin's Herbarium.

The Silver Maples' second act is the helicopter show. All June long. Yup. Tip: if your garden is already well mulched w/ leaves and wood chip or bark mulch, most of the keys will just decompose to become mulch themselves. Then later i just pull out any seedlings that did germinate.

Silver Maples' third act? A subtle sleeper: a breezy, big and balmy, sweet summer song.

It took me years to recognize it, but the sound of warm summer winds swirling around the leaves of big old Silver Maple is one my best childhood memories. Especially in concert with the leaves of willows and cottonwoods. All shoreline species. If you don't know those sounds, come a warm day in summer, they're worth a listen.

Myself, I'm so used to hearing all of those leaves along water edges and shorelines -- creek, riverbank, bay, beach -- on cue I can imagine a common concurrent sound: the slow rhythm of waves: crestfall or gentler lick-and-lap. Pause. Swash back out. repeat.

Sometimes even now, when I'm in those sounds, for split seconds I am 3, 5, 9, 12 or 15 (often all-of-them-at-once), sun/mud/silt-browned, forearms sparkled with sand, my barefoot and bathing suited body is small and close to the ground, running along southwestern Ontario water edges and shorelines. The wind smells of small fires, fish (pickerel, perch, catfish, sunfish and the throw-'em-back sheephead: unless we kept the "j" stones / otoliths from behind their eyes for good luck) and some times charcoal from a hibatchi BBQ. Salamanders, turtles, muskrats were common sights.

Cool ground on my back when I'd lay down under those trees, those leaves, half closing my eyes so i could look up into the changing blurs of dappled sunlight. What a lullabye that seems now.

"...Down the rivers of the windfall light ...I ran my heedless ways ...Time held me green and dying / Though I sang in my chains like the sea" -Dylan Thomas, Fern Hill.

Funny now, how I had to move all the way to this street in Toronto, to learn for the first time that "Silver Maples" was the name for a windsong I had already always known.

My own private three leaved Boneset

My own private "three leaved" Boneset, May 2006

This is a Boneset Eupatorium perfoliatum. Really.

You've likely seen Boneset before, maybe in a meadow, moist prairie, shoreline, a roadside depression, or perhaps in native plant gardens ...often alongside its Eupatorium cousin Joe-Pye weed in late summer. If so, you already know the most distinguishing characteristic about a Boneset is its alternating *pairs* of leaves: two opposite leaves joined at the base perforated by the stem (hence the epithet / species name perfoliatum) aka "connate" leaves. That's right: Bonesets have pairs of leaves. But the youngster in these pictures? He was having none of that, instead he just kept unfurling leaves in *trios*.

What's the botanical term for "aberration"? When a plant deviates from the usual? i think the word i'm looking for is "atypical" or is it "aberrant"? The phrase seems to be "conversation starter."

What ever the terminology, this plant was a maverick. It appeared suddenly one year, out of a large existing clump of Boneset in my back yard, and though that clump is still alive and happy, this 3-leaver never reappeared. Or at least it never appeared with the "3 leaf" thing the following year. BTW: after it bloomed, I sowed its seeds, but I've had nothing like it since.

I've tried looking it up, but I never found images or accounts of another occurrence. To this day i still don't know what to make of it.

Do you? Myself, I've thought 1) more leaves = more photosynthesis & that could be an advantageous adaption, or not. 2) wonders wrought by post-landfill urban soil or possible contamination along the railroad tracks where i initially collected the seed from -- anything is those soils act like some kind of plant mutation catalysts? and 3) just, wow: evolution, it's always happening, never complacent, never a day off.

i know i miss the way that just seeing this guy in my yard every day often made me laugh to myself in a "Mother nature - you funny!" kinda way. Especially whenever i casually swept my hand toward him by way of introduction to native plant gardener friends -- who were inevitably just as surprised, put-to-wonder, and left smiling by this cowboy too.

ALUS: farmers & stewardship

For folks interested in how rural agriculture + natural heritage restoration / conservation can support each other, and profitably too, well, i keep directing my out-of-town friends over to the Norfolk Alternative Land Use Service Pilot Project (ALUS).

Currently I only know of ALUS in Norfolk County Ontario (as i like to say, "they have a mature stewardship culture there"), but i like to hope ALUS will become an Ontario-wide Alliance. Especially since, as that page says, "the vast majority of land in southern Ontario is owned by farmers, especially in the Carolinian zone where 97% of land is maintained by farmers."

To get a feel for the kind of innovative stewardship work they’re doing, this page lists some of what's going on ALUS's demonstration farms.

No, really. Click through that last link. There are some cool, exciting and encouraging stewardship initiatives in there I haven't heard or read about anywhere else. For example: "1.39 acres of pollinator habitat in the form of Pollinator Hedgerows - perhaps the most groundbreaking effort of the Norfolk Pilot, the pollinator hedgerow is aimed at finding solutions to restore populations of native pollinators.”

*

Also, if you (or any of your friends with rural farm properties or stewardship projects) want to learn more about ALUS, here’s an upcoming opportunity:

Friday, March 26th 2010
9:30 am -3:30 pm
ALUS and Ontario's Climate Change Policy: Where does ALUS fit, and why?
Ontario Ministry of Food, Agriculture, and Rural Affairs in Guelph, Ontario
The steering committee of the Ontario Alternative Land Use Services (ALUS) Alliance would like to invite you to attend “ALUS and Ontario’s Climate Change Policy: Where does ALUS fit, and why?” information session. The session will discuss the role of ALUS in the new world of climate change and carbon markets and will focus on how the ALUS Alliance can work within the new policy context of Ontario to make ALUS a provincial program.

The Ontario ALUS Alliance meeting is a free, all day event. Lunch and light refreshments will be provided. The event agenda will be posted shortly on the Norfolk ALUS website http://www.norfolkalus.com so please visit for more details.

Registration is required and will be on a first come first serve basis. To register, contact Kristen Thompson, ALUS Project Coordinator at (519) 426-5999 ext: 2220 or by email at kristen.thompson@norfolkcounty.ca. Please include any dietary restrictions.

Have you seen this cat? Because...

Have you seen this ...? Because...

LMAO! i already want to make a poster like this for, well, an AWESOME local White Elm i know -- hey, who can afford an "official plaque" or "didactic panel" these days?

i wish i knew who to credit this poster and photo to - it's like a local 'natural heritage appreciation' campaign waiting to go viral ;)

Native Plant Buyers and Growers guidelines - SERO

The Society for Ecological Restoration – Ontario Chapter (SERO) has just posted revised editions of their Native Plant Buyers and Growers guidelines.

For buyers and growers: it's informative and insightful. And for what it's worth, I trust SERO and they've never let me down.

For everyone currently struggling for direction, sustainable standards and policy in a changing industry? (And, yes, this is an appeal to you folks who plan on attending next week's Sustainable Hort. Symposium). Please check out these guidelines. Good, talented folks here in Ontario have contributed (volunteered) years of their time and experience to build the most well-thought-out and practical standards that exist on this subject, any where.

BTW: SERO's working on its 2010 Native Plant Resource Guide. More details to come!

hey Guelph hort students :)

This is a shout out to you U of Guelph Hort Cert. students who've been dropping in lately. Thanks for coming by and hope you're having a blast in your courses!

I took the "Naturalized Landscape" course in the Sustainable Landscapes Certificate a few years back. Learned a lot! Still use the materials for reference. Donna Havinga taught it back then. She and Jean Marc-Diagle wrote the text, and Lorraine Johnson edited it (the text book alone was worth every penny. I don't think you can buy the textbook outside of the course). It was one of the best courses I've ever been in. Assignments were practical and focused on each person's bio-region. Also, it was my 1st time as a student in an online learning /distance education format and as it turned out, the medium and flexibility really worked for me. And so did the fact that i had to concurrently learn how to independently suss out and get handy with online resources - skills in themselves which remain useful. And i loved Donna as an instructor too.

The text book was based on Donna's and Jean-Marc's earlier book "Restoring Nature's Place" (revised edition 2000. it's a must read in Ontario, and endorsed by the Society for Ecological Restoration International). It's become increasingly difficult to find (even in libraries), but if you're interested, you might still be able to buy copies for approx. $40 + $8 shipping and handling, by contacting Ecological Outlook at 905-939-8498, toll free 1-877-467-2079 or info@ecologicaloutlook.ca

oh, hey - is the online "coffee shop" still there? I missed that patch-of-ether when the course ended. Coincidentally, i just got an email from a native plant geek friend I met in there. :)

BTW: if you have criticism or suggestions for this site, pls lemme know. Thanks again, and good luck w/ your assignments!

How do I tell the difference between the native and invasive...

1. ...Phragmites?

See "Phragmites: Common Reed - Morphological differences between native and introduced genotypes" at Cornell's Biological Control Program


2. ...native American bittersweet vine Celastrus scandens and the invasive exotic oriental bittersweet C. orbiculatus?

"Using fruit and leaf characters, the two species can be discriminated from each other. However, certain traits are more reliable for correct identification than others. Classically, the position of the fruit and flowers on the stems has been cited as the most definitive means of discriminating between the species. Oriental bittersweet has fruit and flowers located in the leaf axils along the length of the stem. American bittersweet, however, only has fruit and flowers in terminal clusters. There is also a difference in the color of the capsules surrounding the ripened fruit in the fall. Oriental bittersweet has yellow capsules, while those of American bittersweet are orange. Another difference in color is the pollen color of the male flowers. The pollen of oriental bittersweet is white while that of American bittersweet is yellow..." - American and Oriental Bittersweet Identification - the US Geological Service's Great Lakes Centre
Note: along a couple southwestern Ontario roadsides, I found both species side by side + the hybrid species of the two. So I couldn't even seed collect from the native species, because of the possibility the flowers had been cross-pollinated / its seeds would be hybrids.

3. ...native eastern Wahoo
Euonymus atropurpurea vs. the invasive exotic winged burning bush E. alata, climbing euonymus E. fortunei and spindle tree E. europaea?

Unfortunately, around here, it's probably the exotic -- I haven't stumbled by the real thing yet -- still to be sure (and you have to be because there are a few out there + some native plant nurseries sell them = some one's planting them some where) the best native vs invasive
euonymus ID advice I've found is on page 123 of “Growing Trees from Seed - A Practical Guide to Growing Native Trees, Vines and Shrubs" by Henry Kock with Paul Aird, John Ambrose and Gerald Waldron:
European spindle tree E. europaea [exotic]: the identification of this close relative of E. atropurpurea can only be made with certainty at flowering time. The European species has greenish white flowers in late May as compared to the maroon flowers (in June) of the native wahoo. The European spindle tree holds its leaves much longer into the fall, and the twigs tend to be thicker and more rigid than wahoo. However, due to variability in both species, the two are occasionally so similar vegetatively (including the root sprouting) that without knowledge of the flowers, the nearly identical fruit should be left alone – or the flower colour should be verified in late May.

Winged burning bush E. alata [exotic]: A dense, outward-arching bush originating in Japan. It has small orange fruits on short stems that persist into the winter. Twigs on this species are prominently four winged, a characteristic that is more diminutive on a more compact-growing horticultural cultivar but still gives this species a distinctly square-stemmed appearance.

...
[Besides these] two 'ornamental' deciduous shrubs that ...have become naturalized (extensively in many places) in close proximity to older settlements and parks ...garden escapees of the evergreen-leaved Euonymus fortunei [exotic climbing euonymus aka wintercreeper] are also beginning to find their way into the wild."

Ecological Imperialism: The Biological Expansion of Europe, 900-1900


Earlier this year, in an Aliens-L list serve post, Randy Westbrooks recommended "Ecological Imperialism: The Biological Expansion of Europe, 900-1900" as "a ‘must read’ for anyone who works on invasive species."

So I bought it. Now, I'm nearly finished reading it, and he's right. (But what else would I expect: invasion ecology isn't just science, it's sociology and culture and story, and if you've ever talked with Randy Westbrooks or heard him speak, you know that he "gets" story.)

It's helping me understand our current invasive issues + what was, and what's still left of, our natural heritage, in ecological, biogeographical, biopolitical, historical and social contexts.

With memorable examples and well-researched historical accounts I haven't come across anywhere before.

Personally, I especially appreciated any of the historic records of natural and ethnobotanical vegetation in eastern North America at the earliest points of first European contact.

First written in 1986, with a new edition in 2004, this book reminds me of the quote: "The worst thing about new books is that they keep us from reading the old ones." - Joseph Joubert

If you're interested in invasion ecology and natural heritage -- or if you liked Jared Diamond's "Guns, Germs and Steel" or Ronald Wright's "Stolen Continents -- you'll appreciate this one.

~+* snowflakes *+~

"British Novelist Jeanette Winterson commented: They say that every snowflake is different. If that were true, how could the world go on? How could we ever get up off our knees? How could we ever recover from the wonder of it? Though written centuries earlier Francis Bacon has a response: Begin doing what you want to do now. We are not living in eternity. We have only this moment, sparkling like a star in our hand—and melting like a snowflake..."

Henry Kock's "Growing Trees from Seed - A practical guide to growing native trees, vines and shrubs"


If you even think you're interested, buy it.

To find out more please see the book's website.

I've just finished collecting some of the later seeds from my Shrubby St. John's-wort (I agree with the book: these are "lovely shrubs ...deserving more use in sunny yards, including edge of pools and stream gardens"), and with them I marked the end of my first year with this book. It has taken me that long to read it simply because it takes at least all four seasons to observe what it has to teach, not just about seed collection & propagation, but professional and personal lifetimes' worth of growing, conserving, observing and educating people about our native trees and many of our shrubs too. Most of it was new to me.

The first few chapters are treasures of practical and experienced seed collecting, propagation and even restoration advice. Next, specific advice about collecting and propagating by family and species. All the while, the handy reference charts at the back of the book show you month-by-month which species' mature seeds you can expect to find and their stratification protocols.

I began to read what I could already use and understand late last fall. For the 1st time in my life, I realized that the phrase "instant classic" could even be trusted. By summer it wasn't a book or a manual or even a guide so much as a wise, warm and gentle field companion. Like walking land with an extra set of the finest tuned eyes. I love how intuitively organized and accessible this book's format is, and its unmistakable voice too: like the best teachers, it doesn't care about what it 'knows' as much as presenting information and guidance in ways that will enable the reader to learn. And it knows what you want (and need) to learn, even before you do :) After awhile I had to laugh each time it inevitably anticipated and answered my questions while I was still fumbling to formulate them!

I was especially grateful each time it anticipated any confusion I would have about similar and introduced species and hybrids. Not that it's a beginner tree ID guide (I still needed those. If you do too: see native plant ID links in the right side bar. Also, after basic ID guides, Gerry Waldron's Trees of the Carolinian Forest: A Guide to Species, Their Ecology and Uses is an especially apt companion to this book), but it is uniquely helpful for fine scale ID.

To the family and friends of the late Henry Kock, co-authors and editors Paul Aird, John Ambrose and Gerald Waldron and all the good people who helped complete, fund, support and steward this important book into being: I hope you will always know you have given us all a gift that can't be measured. *thank you*.
