Advantages and disadvantages
Many of the advantages and disadvantages of general listing methods apply to TSCs and, again,
this method has the major advantage of being quick. Common species are ignored once first seen and thus effort can be concentrated on finding less common species. A reasonably large area
can be covered in the allocated time. The method is easy and does not require prior mapping
or cutting of transect lines, and is a good way of rapidly evaluating the importance of sites. If,
however, densities of common species are of interest then this is not a suitable method. Timed
species counts provide only crude, relative indices of relative abundance. Maps of distribution
and geographical patterns of abundance could be produced using this method.
