Restoration planning and implementation

Pulling from the lab's >20 years of experience in the field of wildlife restoration and a global network of collaborators, in 2016 we published the book "Reintroduction of Fish and Wildlife Populations" which is a step-by-step guide to planning, implementing, and evaluating the successful re-establishment of fish and wildlife populations. 

Since that book, we regularly advise species restoration and recovery projects, and publish articles on frontiers to advance the field.

Swift fox restoration

Over the past decade we have been working with colleagues in the US and Canada on the successful restoration of swift fox populations in northern Montana.  Despite being successfully reintroduced in Canada over 3 decade ago,  swift fox are rarely observed in this region which serves as a critical link between the population in southern Canada and established populations to the south in South Dakota and Wyoming.   We have conducted tracking studies of swift foxes and deploying a wide camera trap array to begin to address what limits the recovery of connectivity between these populations.

In 2020, we became involved in efforts to help restore swift for to Ft. Belknap Reservation which is the homeland of A’aniiih and Nakota communities.  If successful, this reintroduction effort could be key to connecting northern and southern existing population of swift fox in the Northern Great Plains.

Wildlife Restoration in Working Landscapes

In 2018 we started a new integrative and interdisciplinary project on defining multi-species wildlife restoration potential in the Northern Great Plains. Interdisciplinary in that we are teaming up with social scientists to link ecological and human dimensions data to help define the patterns and processes that have driven and will drive the future of success of recovery entire communiteis of extirpated or endangered wildlife on this working lands landscape.

Bringing back bison

In central Montana, there is an attempt underway to create the largest bison herd in the world.  Bison have been termed by some as a keystone species on the Great Plains, driving the structure and function of the prairie ecosystem.  However, there are concerns regarding the impacts of year-round bison grazing and its potential impacts on grassland plants.  We are evaluating the impact bison restoration has on plant community dynamics both now, and with the establish long-term monitoring plots, long into the future.
