It's been a month since my last blogpost, my apologies. The long winter in the eastern US crossed my plans (see previous posts) and delayed the beginning of the "insect season". The first dragonflies are emerging now, but I have not enough material for a post about them, yet.
Thus, I want to show a few images that I took on my way home from work. They might not be high quality, but I will show them anyways. First, have a look at this video I shot of this interesting creature (play in HD).
Beavers are herbivores, they feed on shrubs, herbs and Waterplants. In addition, they cut down trees and eat their twigs, leaves and bark. This makes him a troublesome pest for forestry. A beaver can bring down a 50 cm thick tree in one night and thus cause enormous damage.
To prevent damage, young trees are protected by netting wire, as you can see in the following two images.
Interestingly, humans and beavers came to an agreement at Beebe-Lake. Every year, the trees near the walkway are trimmed. Instead of being shreddered, these branches are deposited next to the way. During the night, the beavers drag them in the water, which leaves visible traces in the gravel path. In the image below the beaver stopped his raid half way through.
Although not all trees at Beebe-Lake are protected by wire, I could not find any fresh damage. It seems that the buffet deposited by the humans is sufficient for their needs and the beavers got lazy. A great example for effective beaver conservation efforts.
Thanks for reading and see you next time with some insect images, hopefully
