Counts vs Pollard Transects

[Michael Gochfeld]

As I recall Trinidad (35 years ago), there are tracts through the bush, which
are about a jeeps width---maybe 3 m wide total.  These would be effective
transects for low-flying butterflies.  Canopy dwellers are a problem.

Yes,I think the transect method worked well at Monks Woods because of the
habitat and the fact that they already had their "rides" layed out.
