1)birds- netting;
Scientists use a fine net to capture birds and other similar animals (like bats). They can also be used in the water to capture fish. They are identified, and may have blood taken to study them. These animals are safely release. 2)deer-tagging and tracking
Bigger animals are tagged with Gps so that they can be tracked, meaning that the scientists will always know where they are just by "reading it" in the computer. This allows them to study, for example, migration of this animals.
3) insects- canopy fogging
Canopy fogging allows to collect information about the biodiversity of insects. Insecticide, in a low dose, is sprayed were the insects are. With a large funnel, placed were they can fall,they will be observed by scientists
4) trees-quadrat sampling
A quadrat is a area in a shape of a square that is marked using plastic with same area and shape, or stakes and string. The are can vary between 1 m2 to 20 m2, depending on the type of habitat surveyed, making it useful to count Different species of trees.
