This Species Conservation Assessment was prepared as part of a Species Conservation Project
funded by the Wyoming Bureau of Land Management. It represents a complete review of the
current published information available for the species, includes consultation with experts, and
addresses as much as is known concerning the distribution, biology, ecological niche, and
conservation planning being conducted for this species on a state and range-wide level. The reader
will note a number of areas in which biological and ecological data are not well known for this
species, and that distribution data are based on relatively few specimen and observation records.
Systematic surveys of suitable habitat for Euderma maculatum have not been completed in
many U.S. states or Canadian provinces, and data are lacking for the expected range in Mexico.
Wyoming is one of the many states in which suitable habitat has not been identified and
quantified, and surveys of known suitable habitat have not been completed. Although based on
only a few records, general distribution is known for the Bighorn Basin in Wyoming; but recent
records in southwestern and central Wyoming indicate that additional work is needed to identify
potential habitat in those areas. Surveys of potential habitat are needed to verify distribution and
delineate local populations. Because Wyoming may include habitats that are at the upper
altitudinal range of E. maculatum, distribution in Wyoming, and an understanding of population
structure and dynamics of E. maculatum in the state may be very significant for management of the
species across its range.
