As a kid from Iowa, Jason grew up enamored with how the natural world managed to exist in a heavily modified agricultural landscape. His biocentric wonder led him to New England, where he is a quantitative ecologist with the Vermont Center for Ecostudies helping to oversee the citizen science project, Mountain Birdwatch, and research into montane ecology. A quantitative ecologist and ornithologist by training, Jason joined the Vermont Center for Ecostudies in January 2015. A lifelong birder and naturalist, Jason followed graduation from the University of Montana (BS, Wildlife Biology) with a series of wildlife-based adventures that found him monitoring sea otters in California, tracking endangered Red-Cockaded Woodpeckers in Florida, and researching House Wrens at La Selva Biological Station in Costa Rica. On Maui, his crew was tasked with capturing the three remaining po’ouli: a Hawaiian honeycreeper that is now thought to be extinct.
Jason investigated the post-fledgling ecology of Saltmarsh Sparrows at the University of Connecticut (MS, Ecology), and completed his PhD with the Pennsylvania Cooperative Fish and Wildlife Research Unit at Penn State University, studying the population ecology of grassland sparrows following experimental landscape manipulation. During a cooperative post-doc between the Pennsylvania Cooperative Fish and Wildlife Research Unit and the Patuxent Wildlife Research Center, Jason estimated the effects of landscape changes from Marcellus natural gas development on the populations of interior forest and grassland bird species.
Here at the Vermont Center for Ecostudies, Jason wears many hats. He primarily investigates avian ecology within the montane spruce-fir community, but he also coordinates the Suds & Science discussion series and cranks out R code on demand for his colleagues.
In his free time, Jason enjoys paddling, hiking and observing nature (follow along with my adventures on iNaturalist.org; see my recent observations below). You can often find him ascending rock walls or hitting the trails with his son, Heron, and permanent belay partner, Katie. And he is still a kid, at heart.
