Blue Lettuce

The Blue Lettuce (Lactuca tatarica) is a species in the genus Lactuca. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.
