More Spring goodness!

Despite the early April snow, our native plants are showing courage and beginning to grow.  Yesterday, I visited the colony of Skunk Cabbage, Symplocarpus foetidus, Aracacae, that grows south-west of Orangeville right alongside a well-travelled road. (You can see the road gravel thrown off the roadside by the snow ploughs in one of the photos.)

Skunk Cabbage is a fascinating plant with several quite unusual adaptations to getting an early start in Spring. Its upper parts are capable of generating a significant amount of heat:  15+ Celsius degrees above ambient air temperature! This added heat seems to accomplish several functions simultaneously. It means that Skink Cabbage can literally melt its way through snow. It means that the warmth inside the flower helps keep the early pollinators basking in the extra heat, hanging around and maximizing the chance that they will transfer pollen to the benefit of the plant. It also means that the rising warm air spreads the pungent smell that comes from broken leaves and from the   spadix as it flowers. The rising warm air may also enable a small amount of wind pollination!

Skunk Cabbages are related to Jack-in-the-Pulpit, and share several general features. The cut or bruised vegetation releases a pungent smell. Plants have important underground storage organs, a corm for Jack-in-the-Pulpit, and a huge rhizome (an extended corm, I suppose — or perhaps the other way round:  a corm is a shortened underground stem or rhizome) for Skunk Cabbage. Supposedly, the rhizomes of the Skunk Cabbage can reach 30 cm in diameter! While Jack-in-the-Pulpit corms are poisonous, and Skunk Cabbage is not, both species were important Spring or Fall food sources for indigenous peoples, who learned how to prepare the edible portions by drying or baking before consumption.

The other major feature shared between the plants of the Aracaceae is that the flower is wrapped by a spadix or surrounding leaf-like structure, and has as its central core a spathe, a spike-like structure that holds either the male or the female parts.  In the first picture of the Skunk Cabbages, the lovely red-mottled spathe surrounds a thick paler yellowy-brown spadix down inside.

By the way, I knelt down in the marsh beside the road to smell these Skunk Cabbages — and they didn’t yet smell.  Not quite ready for action!

An update after our early Spring snowstorm!

I went out mid-day on Friday April 7th as the sun was beginning to warm up the air and melt the snow that had blown in on top of the sprouting Skunk Cabbages.  They seemed to be having no trouble with the weather — it had only gotten just below the freezing point, after all.  But they were certainly not melting any snow yet.  I suspect that’s because the air temperature is still too cool for any insects to be flying.  Somehow the plants seem to understand to get ready, but not to actually push forward on actual flower development.

Spring is here — finally!

March 2017 was colder in this area than February 2017, by a minor fraction of a degree.  More significantly, March was almost 5 Celsius degrees colder than the climatological normal for Southern Ontario.

But it looks like it’s finally here!

One of the harbingers of Spring for me is the opening of the Silver Maple (Acer saccharinum) flowers. In my backyard on the edge of Orangeville, the female flowers opened yesterday on 2017 April 01, and then safely enough to remove any doubts about an April Fool’s joke, the male flowers on the adjacent tree began opening today!  Only just opening and beginning to shed pollen, but I’ll still count this as Spring!

I’ve also had a Fox Sparrow at my bird feeder. I count that as another harbinger of Spring.

Female Silver Maple flowers are finally open!

Male Silver Maple flowers from an adjacent tree are also gingerly opening up and beginning to shed pollen into the air.

Christmas Bird Count done!

Thanks to the more than 20 people who turned out to do our annual Christmas Bird Count on Friday December 30th!  Special thanks to Ron Jasiuk and Russ McGillivary for their organization and to Kevin and Carol for hosting the fine potluck dinner afterwards!

UCFNC Christmas Bird Count areas

Russ will compile the results from our six different teams and from the others who contributed Feeder Watch data. We’ve not got a preliminary guess as to how many species nor how many individual birds we say. What we can say is that because of our cold weeks earlier in December there was no open water other than in streams and creeks so that our large numbers of waterfowl from last year were all but absent this year. It’s not about bigger or better numbers — it’s about getting as detailed an inventory each year to build into larger patterns. Let’s see how this the numbers from this year turn out!

I had the great fortune to be out in Area 2, southeast of Caledon over to Caledon East with wonderful birders. Hart brought along Gordon, a friend of his from the Nature London Club and an experienced birder. I’m always in awe of folks with good ears — and Gordon certainly had them. The others would hear things that I couldn’t even with my top-quality hearing aids turned up fully.

Can you see the Red-tail Hawk sitting in the tree down the field — and can you spot the Rough-leg flying away up and to its right?

Highlights for me:  spotting a Belted Kingfisher (and hearing another) at the spot that Chris P had seen them at for many years down at the bottom of the Escarpment along a branch of the Credit River — and seeing a cold-looking Great Blue Heron at the same spot!; being shown a Rough-legged Hawk sharing a tree and sitting directly above a Red-tailed Hawk along the Grange Sideroad east of Highway 10; (the Rough-leg took off leaving the Red-tail sitting in the tree; look closely and you’ll spot the Red-tail in the tree near the middle of the photo, and possibly see the Rough-leg flying away just above and to the right in this mobile phone photo); learning that Gordon had worked with an amazing birder with whom I spent a marvellous summer way back in 1972 working on an ecological inventory of Prince Edward County; getting together with almost everyone afterwards and sharing sightings and stories; wandering up and down the side roads and concessions of Caledon, looking at the wonderful diversity of habitats — and yet realizing how remarkably young almost every top of forest actually was.

John Muir in our Headwaters area!

Our Southern Ontario area plays a special role in the development of what we now call the environmental movement.  Few of us know much about this pivotal role.

Starting in the Spring of 1864, the young Scotsman turned American, John Muir, spent several months botanizing through Southern Ontario. This was his first real exploratory trip beyond his adopted home farm in Wisconsin.

It was over in the Pottageville Swamp area (what was then part of the much larger Holland Marsh) that he had one of his most significant events of his lifetime, seeing a rare northern orchid, Calypso borealis. This epiphany started him on his way to dedicate the rest of his life to the preservation of the natural world.

“The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one’s way through. Entering one of these great tamarac and arbor-vitae swamps one morning,holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey’s nest, or eagle’s, or Indian’s in the flooded forests of the Orinoco described by Humboldt.

“But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung. The flower was white and made the impression of the utmost simple purity like a snowflower. No other bloom was near it, for the bog a short distance below the surface was still frozen, and the water was ice cold. It seemed the most spiritual of all the flower people I had ever met. I sat down beside it and fairly cried for joy.

“It seems wonderful that so frail and lovely a plant has such power over human hearts. This Calypso meeting happened some forty-five years ago, and it was more memorable and impressive than any of my meetings with human beings excepting, perhaps, Emerson and one or two others.” (John Muir, re-published in The Life and Letters of John Muir,1924 (After his death))

Sometime during June of that year, he passed through our Headwaters area, walking westwards along the Hockley Valley from the Holland Marsh to the Luther Marsh. Later that year, he ended up outside of Meaford working in a rake-making factory. When the mill burnt down in the winter of 1866, Muir returned to the United States.

Muir ended up in California where he started the Sierra Club, still one of the leading environmental action organizations.  He is regarded as one of the fathers of the American National Parks system.

Speaker’s Night Topic a “Must Learn” Opportunity

mustdo_dp19647049_deer

Our upcoming talk was identified as a “Must Learn” opportunity in the most the recent issue of “IN THE HILLS” magazine.

You can’t live in Headwaters without having an opinion about deer. You worry about them crossing the road. You love seeing them run across open fields. Or maybe you fret about your gardens or farmland – aka your local deer family’s favourite salad bar – and wonder when hunting season begins.
If you’d like to learn more about the species we share our space with, head to the Upper Credit Field Naturalists speaker’s night on Tuesday, March 29 for Deer Biology and Management in the Headwaters Region. Biologist Graham Findlay from the Ministry of Natural Resources and Forestry will share the basics on the creatures and what goes into managing them in our area. The talk is free and takes place at the Orangeville Seniors’ Centre at 7:30 p.m. uppercreditfieldnaturalists.org
