Mark and Recapture: Population Sampling

High School Science » Unit: Populations

Taylor Wichmanowski
Los Angeles, CA
Environment: Urban
 
Big Idea:

Counting every individual in a population is almost always impractical if not impossible. Ecologists can use sampling methods to make reasonable estimates of population sizes.
