Tyler Dungannon: I grew up an avid outdoorsman in southern Oregon’s Rogue Valley. My predilection for hunting and studying game species led me to Eastern Oregon University, where I received a Bachelor’s of Science in ecological biology. Prior to joining the Hagen lab in 2018, I worked for Oregon State University (OSU) as a research technician on several research projects focused on avian and mammalian predators, corvids, gamebirds, and wild ungulates.

As I pursue my Master’s in Wildlife Science at OSU, my research is focused on resource selection of greater sage-grouse. Specifically, I am investigating how varying thermal signatures influence sage-grouse brood habitat use and selection at a microscale. Concurrently, my project is collecting demographic data to augment an existing dataset obtained by projects in the Warner Mountains focused on quantifying the effects of conifer removal on sage-grouse.

Christopher “Digger” Anthony:  I was raised on the east coast (Pennsylvania, Florida, Massachusetts); however, I grew up out west (Oregon, Washington). I received a Bachelor’s of Science in Ecology from Evergreen State College and a Masterdigger3’s of Science in Wildlife Science from Oregon State University (OSU). Prior to pursuing a Ph.D., I worked for 9 years as wildlife biologist for the Bureau of Land Management in Prineville, Oregon. My worked primarily focused on maintaining and improving habitat quality for forested and shrub-steppe flora and fauna.

I am broadly interested in wildlife-habitat relationships, landscape ecology, and population ecology. More specifically, I am interested in how anthropogenic and natural disturbance influences population dynamics, resource selection, space use, and movement of wildlife across spatial and temporal scales. My current research at OSU examines the response of Greater Sage-grouse to broad scale wildfire. The main goal is to better inform management by addressing population and habitat issues related to fire and sage-grouse. In detail, I am using several spatially explicit models to characterize population trends, resource selection, resistance landscapes, and source-sink habitats of sage-grouse in a fire affected landscape.

Andrew Olsen:  I joined the Hagen lab in 2015 after completing my M.S. in Range and Wildlife Olsen_Pic (002)
Management at Texas A&M – Kingsville where I studied the helminth parasites of Northern Bobwhites and Scaled Quail.  Prior to my M.S., I earned a B.S. in Biology from Northwest Nazarene University where I studied amphibians in Idaho and Costa Rica.  My research at OSU focuses on the effect of western juniper on Greater sage-grouse demographics and movements.  Conifer encroachment is considered a threat to sage-grouse populations and wide spread removal of conifers, including western juniper, has become a common conservation practice across much of  sage-grouse range.  We hope to document response of sage-grouse to landscape-scale conifer removal near Lakeview, Oregon using VHF and GPS telemetry.  When I’m not working , I enjoy hunting, fishing, & birding.

My take on the larger project to which I’m contributing:  One of the primary conservation actions of the NRCS funded Sage Grouse Initiative (SGI) is coordinating and funding conifer removal on private lands across the west.  Although conifer encroachment is regarded by many as a threat to sage-grouse, there is little documentation of positive demographic impacts as a result of conifer removal.  Results from my study will evaluate the hypothesis that conifer removal will benefit sage-grouse populations, and will inform the ongoing and extensive conifer removal projects that SGI is already conducting.

laraschickLara Schick I grew up in the Lehigh Valley area of Pennsylvania where I earned my Bachelor’s  in Environmental Studies from Albright College.  I am a Master’s student in the Wildlife and Fisheries Administration Program, which I am pursuing online though Oregon State’s Ecampus.

I currently reside in Pinedale, Wyoming where I work as a wildlife biologist for an environmental consulting firm. Currently, I am project lead for the annual wildlife monitoring on the Jonah field; one of the nation’s largest natural gas fields.  Surveys for this project include mountain plover, pygmy rabbit, song bird, burrowing owl, sage-grouse fence collision, prairie dog, and raptor nest monitoring. Also, I am involved in monitoring for wildlife along the New Fork River corridor during the installation of a well pad, wetland delineations, and vegetative assessments.

Through the Fisheries and Wildlife Administration program I strive to enhance my knowledge base and skills in wildlife biology and natural resource policy and management.  Long term, I aspire to become a state or federal wildlife biologist.  My program requires an internship project in lieu of a graduate thesis. I am still in the initial stages of developing my internship, but would like to focus on some aspect of avian biology or conservation. In my spare time, I enjoy birding, backpacking, trail running, hiking, biking, fishing, kayaking, and in the winter cross-country and downhill skiing.
