T&E Butterflies 
This legal designation of Threatened and Endangered (T & E) Butterflies requires the National Park Service to monitor and evaluate the condition of these populations. Because they are closely tied to host and nectar plants, butterfly populations are good indicators of the general health of habitat. These taxa have very specific habitat requirements during different developmental stages, including specific host and nectar plants.
Monitoring ObjectivesDetermine the trends in population distribution and relative abundance of threatened and endangered butterflies within known habitats in GOGA and PORE. Detect changes in acreage of habitat available for butterfly populations at GOGA and PORE such that potential impacts on the butterfly populations may be identified. Predict and identify new lupine habitat annually in order to identify new butterfly populations.
