  abstract = {Cutting straight line transects through dense forest is time consuming
	and expensive when large areas need to be surveyed for rare or highly
	clustered species. We argue that existing paths or game trails may
	be suitable as transects for line transect sampling even though they
	will not, in general, run straight. Formulas and software currently
	used to estimate local density using perpendicular distance data
	can be used with closest approach distances measured from curving
	transects. Suitable paths or trails are those for which the minimum
	radius of curvature is rarely less than the width of the shoulder
	in the detection probability function. The use of existing paths
	carries the risk of bias resulting from unrepresentative sampling
	of available habitats, and this must be weighed against the increase
	in coverage available.},
