Abstract

The only population of the Devils Hole pupfish (Cyprinodon diabolis) has been in decline or subsisting at low levels for more than a decade. Biannual counts for the last three years (2009 - 2011) suggest that numbers have risen above the historic low point but may no longer be increasing. We discuss management options in light of hypotheses regarding the ecological factors that may be limiting population size and risks associated with various alternative actions. We also provide updates on ongoing research, monitoring and management activities.
