The mark-recapture technique is that after the tagged animals are released, they mix freely with unmarked individuals. The population is resampled and the numbers of marked and unmarked individuals are recorded.

Mark-recapture technique can have drawbacks;

1. Some animals that have been marked may learn to avoid the traps. 
2. Recapture rates will then be low, resulting in an overestimate of population size.

Some animals can become trap-happy, particularly if the traps are baited with food. This would result in an underestimate of the population size.

Clumped: The most common dispersion pattern is clumped, because resources tend to be clustered in nature.

Uniform: Competition may cause a uniform dispersion pattern between individuals. The pattern of trees and seedlings may appear random as seedlings develop from seeds dropped at random.
