Conservation planning maps are important tools in delineating and protecting unique habitats that provide important ecological services. With two species of nectar-feeding bats (federally listed) and 17 species of hummingbirds, some as annual migrants from Mexico, Arizona has the most diverse vertebrate pollinator fauna and specialized flora in the United States. Arizona vertebrate pollinator GIS maps will be useful to ecologists looking for species richness "hot spots" and to conservation biologists trying to delineate and document significant pollinator-plant competitive relationships, especially along migratory pollinator corridors between Arizona and northern Mexico. With recent advances in GPS and GIS technologies, the ability to rapidly map habitats has progressed significantly, while our ability to adequately determine what attributes are necessary to understand the underlying ecological processes has not kept pace. With exponentially increasing spatial data, there is a greater need to integrate, understand, prioritize, and focus on the least amount of data required to create useful decision surfaces that can be used by conservation professionals and decision makers. This paper examines some of the "cost-benefits" of using the Arizona GAP vertebrate pollinator maps from a pollination specialist perspective. Further, we discuss the need to obtain additional ecological information to document the significance of native and nonnative pollinators and habitat relationships.
