General Research Interests

Paige is interested in using quantitative models and stakeholder input to make conservation decisions.  Her research focuses on methods for sampling wildlife populations, hierarchical modeling of ecological processes including observation models, and natural resource decision making under uncertainty and conflicting objectives. 

 

Project Summary

The southern Appalachian Mountains have experienced dramatic rates of land use / land cover (LULC) change over the last 50 years. In general, the LULC changes can be characterized as: (1) increases in forest because of declines in timber harvest, (2) declines in agriculture, (3) increases in urban land cover, and (3) increased fragmentation of native habitat through amenity-driven exurbanization. The southern Appalachian Mountains are also an area of high biodiversity, making changes in LULC a potential concern for species conservation. As birds are known to be sensitive to landscape changes and are readily detected and identified by their songs, they are a suitable focal taxon. Macon County, North Carolina, the location of the Coweeta Long Term Ecological Research site, is a microcosm in which to study the effects of LUCL on birds.
We conducted point counts at 276 sites across a range of LULCs and elevations in Macon County and sampled each site 3 times during the breeding season.  We used a double independent observer sampling design and collected detection data for songbird and woodpecker species. We built a candidate set of occupancy models based on a priori hypotheses relating site- and survey-specific land use variables to avian occupancy and detection.
These ecological finding will be combined with stakeholder values and opinions in a structured-decision making framework.  We will work with stakeholders to elicit their opinions and values, understand their decision making motives and processes, and assess potential for adopting land use and land management practices that are socially acceptable and support avian communities. Further, we will model the effects of exurban development on avian occupancy in other regions of the country that are experiencing similar LULC changes and compare results from the different systems.
