Biodiversity Environmental Science

Lines are drawn on a map and individuals occurring on those lines or belts are sampled

• transects

• quadrats

• point sampling

• mark and recapture

trees or branches are shaken and fallen insects, etc. are collected

• Plankton net 

• Kick sampling

• Pitfall trap

• Beating tray

species help determine the types and numbers of other species in an area, helping to sustain the ecosystem

• keystone

• native

• indicator

• foundation
