In my current postition with Forest Inventory and Analysis (FIA) the majority of my season in focused on field data collecton in central Idaho. During the winter months, I have been working on a project investigating recent pinyon jay declines in the West. The research is focused on using two existing, publicly available, datasets: the North American Breeding Bird Survey (BBS) and FIA. The hope is to be able to see if there are FIA measured habitat variables that might be associated with pinyon jay population trends captured by BBS.
I am interested in investigating wildlife habitat relationships, especially regarding avian species.
I recieved a Masters degree in Fish and Wildlife Management from the Deparment of Ecology at Montana State University in 2015. There, my thesis focused on demographic responses of woodpeckers in relation to a recent mountain pine beetle (MPB) epidemic in Montana. We investigated possible relationships between nest survival and variables relataed to the epidemic as well as other variables (weather, predation, nest tree characteristics, etc.). Additionally, we looked at densities of nests in relation to the epidemic. Our findings suggest that nest survival of cavity-nesting woodpeckers was influenced more by varaibles unrelated to the epidemic (such as those describing the cavity tree and temperature) than variables related to epidemic timing and severity. This may be explained by the high rate of nest survival of cavity-nesting woodpeckers in general, suggesting that this vital rate is not easily influenced by a resource pulse (food and nesting substrate brought about by the epidemic). However, our findings suggest that nest densities of Picoides spp. (species directly feeding on MPB) increased greatly during the epidemic. This may suggest that Picoides spp. demonstrate a numeric, rather than a functional response as a result of MPB disturbance.
