Quadrats - estimating population size of an organism
Eg sand dune ecosystem - some populations -> community -> habitat
Fence - splits area into two regions
Grazed - ungrazed (cattle)
2 areas of ecosystem - study the populations in grazed/ungrazed
Then count the population
Quadrating
Quadrats based on squares - square grids
Up to 1m x 1m
Sample -> counting populations
and estimating the population size
Quadrats -> method of sampling different locations - populations can be compared
