The Worm Turns - April 18th, 2012 - Copeland Forest

The goal today was to gather edible plant life and to study pond life. There was a slight problem with the goal in that the weather has been extremely dry. For a definition and discussion of drought in Canada click here: http://www.thecanadianencyclopedia.com/articles/drought

Since the weather has been dry, things are finding it extremely difficult to grow this spring and that includes the edible plants. Pond life is trucking along normally enough but anything that needs rainfall or snow melt in order to thrive is not doing to well. 

Amanda is a very resourceful person. Since she knew that the lack of rain pretty much meant a lack of plant life, she taught us how to make an earthworm farm. Worms like moist soil and they like darkness since they are nocturnal. To find the worms we had to look under the trees where the earth still had some wetness to it left over from the melting snow. 


A quick google on the www shows that there is much information about worms. Some starting links are here:

The last link has links also to Plantwatch, Icewatch and Frogwatch.

All in all, earthworms get a lot of press and so they should. They are more than just bait. They're integral to the decomposition of matter and the health of the plant life around us.

After lunch we put the worms to rest and went to examine the pond. Unlike the land based life, which relies on rain and snow melt, the pond life is trucking along more or less as it should.

We noted quite a bit of beaver activity along the stream. Beaver seem to be quite artistic and also very persistent. They're also patient. A beaver can fell a tree with a circumference of 35cm or so, presumably to get at the branches on the top, although, as you can see from the treescaping below, they also know how to chop up the trunk.

Hey, they may be a nuisance, but we kind of like beaver.

Right, so there were beaver around somewhere, likely sleeping since beaver are  nocturnal - something they hold in common with earthworms.

There was also evidence of the activity of the Husquavarna Beaver.


In the stream, which the kids helped us ford by way of a makeshift bridge, they discovered frogspawn. Amanda told us that it takes 28 days for tadpoles to hatch. The strength of life and the abundance of it is quite amazing. Nature does things in excess, especially births because the survival rate for life is not as high as one might think. Look up sea turtles for instance.

In fact, some of the eggs we found were in danger of dying because the water level was so low. This afforded a great look at the egg sack but did not bode well for the tadpoles. We tucked them back in to the stream before continuing.

In the pond one of the kids caught a newt or possibly a salamander. Deciding what it is will take a bit of research. Either way, it counts as pretty nifty.

Here we have the link to newt info: http://www.ontarionature.org/protect/species/reptiles_and_amphibians/eastern_newt.php

While we were at the pond the kids renovated the Fairy Hotel. The included a salad bar, a front foyer and some upper level housing. They also decided that the numerous sapsucker holes in the tree could count as rooms. The Fairy Hotel has more going it for it than even the Ritz.

Also, Amanda identified a new twig for us. This is Basswood and the buds are edible. You can tell Basswood from Black Ash because the buds on the Basswood alternate whereas those of the ash are opposite one another. basswood is the tree that leafs out with the enormous green leaves and is largely a ground hugger.

All in all, it was a great day to be out and discovering stuff up to an including small green striped garter snakes, so new n'all.

As the afternoon warmed up and the sun hit the pond we saw it come to life. The water boatmen below were not in evidence when we arrived and were there in abundance when we left. The spring is dry but it's determined to get there.

Twiggy - Copeland Forest - April 2012

Lately we have been out in the woods in less than ideal conditions. We have been pushing the boundaries into the snowy season and the rainy season.This is on a different project than the Young Naturalist. It's an end-to-end hike on the Bruce Trail but is has made us notice that 1) the woods are lovely in all seasons and that 2) the perfect day can come unexpectedly.

Today we went out to our study area in order to learn to identify trees by their twigs. This is a handy skill to have if you're into free range landscaping. It is always better to transplant in early spring or late fall but both seasons tend to leave us leaf-less. Already we know about bark, but the bark in young trees does not always resemble that of the older ones.

Above you see watercress. The Copeland Forest serves as the headwaters for hte Surgeon river and is also a watershed between Lake Simcoe and Georgian Bay. Watercress likes clear running water. Rumour has it that it makes good sandwiches.

This twig is that of a hard maple.  If you look at the twigs you can sometimes see last year's growth. The bark is a different colour than that of the old growth and more delicate.

Maple does flower. Then it leafs out. Here you see tiny new maple leaves, not yet masked by the green of chlorophyll. Remember, leaves are not actually green. When we see them as green it is because they are busy actively making food for the tree.

The two twigs below are those of the Tamarack. This is the confused coniferous tree. It drops its needles in the late fall, turning an attractive yellow and then needles out again the spring. Tamarack likes wet earth. If you plant one of these make sure you're on a wetland.

Here we have apple leaves. The Copeland Forest was once farmed. There is quite a bit of apple out there. Apple is one of those trees easily recognizable by its shape. Whenever we found a young tree, Amanda looked for the mother tree. This is a handy trick to help you confirm your twig-sleuthing prowess. If there is no mother growing near then you probably have the wrong tree.

                              For instance, the next two pics are of Ironwood and Black Cherry.A defining feature of Black Cherry is that the twig looks like a pretzel (and the bark like a popular breakfast cereal). However, we could not see  nay mother tress. What we saw was a lot of Ironwood mothers. Ironwood twigs also look like pretzels. Ironwood buds tend to lie at 45 degrees to the twig whereas Black Cherry buds tuck closer in to the twig. Once it leafs out, the Black Cherry has a distinctive red cast to its leaves.

This is Black Ash. The leaf bud sits right at the top of the stem, sort of like an orb on a fairy wand.

To the right it is Birch. The bud of the Birch looks a bit like the leg of a chicken or the eye of a reptile. It is whorled and looks as though it could collapse back in on itself in case of hard frost. Young birch bark does not look at all like the adult product but birch buds are very distinctive.

Next up, Oak. What you look for in Oak is many small blobs. Again, here you can see last year's growth. It began down near the edge of the picture. That is where the buds would have formed last spring.

To the right is Balsam Poplar. The scent of this one is quite nice.

Last up, the Mighty Beech. Since the winter was mild, many of the Beech still have their leaves clinging to them. You will recall that if the Tamarack is confused then so also is the Beech. However, the new leaves are long, pointed and furled, like pieces of parchment or banners ready to fly for Midsummer.

In addition to the trees, the understory is also poking up through the forest floor. To the right is the speckled foliage of the Trout Lily. This will send out yellow flowers more or less at the same time that the trillium blooms but the leaves do indeed look like fish.
