A comprehensive approach to conserving endangered species requires data on the geographic distribution, habitat, and abundance of species from a wide array of taxa, including invertebrates, lichens, bryophytes, and other poorly known groups. Such information can also contribute to ecosystem‐based conservation efforts. Unstructured surveys by taxonomists can identify species that appear to be rare, but such surveys are inadequate for most conservation purposes. We describe simple approaches for systematically gathering and analyzing more–useful data: using time‐ and area‐constrained searches, recording abundances, listing common as well as rare species, using “control” areas, and characterizing the environmental context of each survey site. The particular methods described are for lichen surveys, but they are directly applicable to bryophyte surveys, and the general principles are relevant to all species surveys designed to inform conservation efforts.
