How to use pitfall traps to sample invertebrate populations in an area?
Since it is not possible to count and identify all of the bugs and beasts on the ground, we can use a pitfall trap to get an idea of what's around. In order to do a pitfall trap, we need to dig a small hole in the ground in which we insert a pot level with the ground. Then, we place a small cover to protect it from predators and rain, but we want that cover to be raised so that the bugs and beasts that we're wanting to trap can get in and fall into the pot.
