Simulating the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species. PRACTICAL SHEET
Modelling a sampling procedure to investigate the abundance of mobile animal species that mix freely with each other in the field.
SUPPORT MATERIALS
A model of a habitat and the distribution of a non-mobile species can be constructed using simulation sheets printed from the Excel spreadsheets:

Distribution of dandelions (less dense).
Three other useful Excel spreadsheets:
