Burning Prairie to Restore Butterfly Habitat: A Modeling Approach to Management Tradeoffs for the Fender’s Blue

Edge-mediated Dispersal Behavior in a Prairie Butterfly

Animal responses to habitat boundaries will influence the effects of habitat fragmentation on population dynamics. Although this is an intuitive and often observed animal behavior, the influences of habitat boundaries have rarely been quantified in the field or considered in theoretical models of large scale processes. We quantified movement behavior of the Fender’s blue butterfly (Icaricia ica...

FINAL REPORT Restoration of Fender’s blue butterfly and its prairie ecosystem: Management applications of fire to Baskett Slough NWR

Patch Size and Connectivity Thresholds for Butterfly Habitat Restoration

Recovery of endangered species in highly fragmented habitats often requires habitat restoration. Selection of restoration sites typically involves too many options and too much uncertainty to reach a decision based on existing reserve design methods. The Fender’s blue butterfly ( Icaricia icarioides fenderi) survives in small, isolated patches of remnant prairie in Oregon’s Willamette Valley—a ...

Author's personal copy Butterfly responses to prairie restoration through fire and grazing

The development of land for modern agriculture has resulted in losses of native prairie habitat. The small, isolated patches of prairie habitat that remain are threatened by fire suppression, overgrazing, and invasion by non-native species. We evaluated the effects of three restoration practices (grazing only, burning only, and burning and grazing) on the vegetation characteristics and butterfl...

The prediction of Persian Squirrel Distribution Using a Combined Modeling Approach in the Forest Landscapes of Luristan Province

Habitat destruction is the most important factor determining species extinction; hence, the management of wildlife populations necessitates the management of habitats. Habitat suitability modeling is one of the best tools used for habitat management. There are several methods for habitat suitability modeling, with each of having  some different advantages and disadvantages. In this study, we us...
