ABSTRACT
This chapter describes threats to habitat function of black-tailed and mule deer that can affect how a habitat performs for a sustainable deer population. Function is measured from low to high and a baseline condition is used to measure the intensity of threat or desired condition for optimal habitat function. Threats are typically seen as a negative or reduction in function and measured by each distinct habitat. There are 5 major threats to habitat function: modified vegetative species, modified vegetative structure, decreased or inadequate forage, loss and fragmentation of habitat, and altered succession and disturbance regimes. These major factors are influenced by changing climate and natural succession and have contributing factors that vary by ecoregion. The location, juxtaposition, and availability of habitat for use also is considered for each threat. Threats can be addressed through mitigation, habitat enhancement, and coordination amongst stakeholders in a comprehensive conservation strategy.
