New Location: Cook's Lake

We started setting new traps in a new location today. Christina's family bought some property near Cook's Lake and they have been maintaining it for almost 20 years as a nature preserve. There is a lot of work involved in helping the land stay healthy for many types of plants and animals, as well as keeping it safe and easy for volunteers to walk around in the forest. Parts of this land get very wet in the spring and create large puddles that will dry up by the summertime. But while they exist, they are extremely important habitat for amphibians, such as frogs. They lay their eggs in the pond and if they time it right, it will be a pond long enough for the eggs to hatch and for the tadpoles to grow enough to leave the water. One project volunteers can help with is building pathways over the ponds so people don't step on these eggs! There's also a beaver at the lake. Beavers are very territorial and there will usually be only one pair of beavers and their kits on the lake. Most beavers here don't build dams because the lakes are already deep enough to build their lodges. We saw some evidence of someone's handiwork! Remember our weevil study? Weevils are a problem here for conifers, not deciduous trees. They lay their eggs in the bark. Well, it's only a problem if you are a forester trying to grow straight trees. It causes a new trunk to grow out of the spot where the old truk was damaged by the weevil, so the tree can look quite bushy after some time. It's great if you're a bear or a porcupine looking for a place to nap. Here's an example of an old white pine with weevils:

  1. I would love one of these trees next to my house. It is a lot more enjoyable to look at than a "normal" tree.
