The equation for estimating density (D = n/2La) can be rewritten in terms of f(0): We know n and L, so we need to estimate f(0). The main problem in line-transect estimation involves developing an appropriate model for f(x) and then using this model to estimate f(0).

What is the transect method?

Line transect sampling is a distance sampling method for estimating the abundance of wild animal populations. One key assumption of this method is that all animals are detected at their initial location. Animal movement independent of the transect and observer can thus cause substantial bias.

How do you calculate population density from line transect?

D= N/A (Eqn 3.2) where D is density, N is population size and A is area. So say we have 100 animals in a 10-hectare plot (a hectare is 100 m by 100 m). Then D = 100/10 = 10/ha.
