Intervals for Repeating Atlases (1995): The recommendation is that
atlases be repeated at 20 year intervals.
Asterisked Species Reports (consensus of 8/11/99 meeting;
subject to modification in regard to data standardization):
Each atlas project should use (as all have to date) a form for "asterisked
species" (i.e. state endangered, threatened, or species of special concern) which
includes precise location data (verbal site description, ownership of land if known,
attached photocopy of map with location circled). Signature of the observer is desirable,
if possible, along with the observers years of experience with the species. After
review by the Regional Coordinator, form should be submitted to the state or provincial
Heritage Program. If further details or forms are needed, the Regional Coordinator should
fill them out to avoid overwhelming the atlas volunteer.
