More Scat!


video
In the last scat video, we worked in a small area of 10m x 10m. After we finished one small area, we would move to the next small area and do the same process again. In this video, we walked a mile down a transect and looked for many different types of scat. We found coyote, deer, hare, porcupine, and raccoon. We also looked for other evidence of mammals such as burrows, food stores, trees being chewed by porcupines and tracks. Why do you think we are using two different methods to find mammals? What does each method tell a scientist?

Scat!

Why are we picking up the Snowshoe Hare scat?
What can the amount of scat tell us about the population?

Cooks Lake




Today we set traps at Cooks Lake, which is a very different habitat than East Port. There are mice, voles, meadow and woodland jumping mice, as well as bog lemming at this site. This area looks more open and less dense than East Port. Using our mark and recapture method, we tallied up our total number of Mice and Voles at East Port to be about 22 per hectare (100m x 100m).
In Cooks Lake, we also put traps in two different areas: meadow and woodland. Where do you think we will catch the most mammals in the meadow or wooded sections of Cooks Lake and also how many organisms do you think we will find at this site? Sorry the pictures posted out of order. The first picture is of the woodland site at Cooks Lake. The second is of the East Port Site. The third is of the meadow site at Cooks Lake and the last is another of the East Port site. Look online to see what habitats mice, voles, and lemmings might prefer.

Halifax




Over the weekend we headed to the main city of Nova Scotia, Halifax. We walked around in the snow and wind, and got to see the citadel where British soldiers used to be stationed in the 1700's. They also have a suspension bridge that looks just like the golden gate. We also went to Kejimkujik National Park and saw an old growth hemlock grove of trees that was about 350-450 years old.
