This report is part of the Habitat Suitability Index model series which provides
habitat information useful for impact assessment and habitat management. The
Habitat Use Information section is largely constrained to those data that can be
used to derive quantitative relationships between key environmental variables
and habitat suitability. The habitat use information provides the foundation for
the HSI model that follows. In addition, this same information may be useful in
the development of other models more appropriate to specific assessment or
evaluation needs for the gray partridge (Perdix perdix).
The HSI model section documents a habitat model and information pertinent to its
application. The model synthesizes the habitat use information into a framework
appropriate for field application and is scaled to produce an index value
between 0.0 (unsuitable habitat) and 1.0 (optimum habitat).
