Younger Innovators: USask researcher tracks impression of Saskatoon’s development on wildlife – Information

City sprawl, the outward development of a metropolis as new roads, housing developments, subdivisions and enterprise districts are constructed, occurs quickly and represents near-permanent modifications to the surroundings.

“A major environmental consequence of city growth is biodiversity loss,” stated Harris who’s engaged on a doctorate in animal and poultry science in USask’s Faculty of Agriculture and Bioresources.

Biodiversity and biodiverse areas are extraordinarily necessary for a lot of causes, together with total human well being and well-being, and environmental well being and sustainability, she stated.


“However, loss of biodiversity is now occurring at a faster rate than at any time since the last historical extinction event that occurred millions of years ago, and we are currently in a global biodiversity crisis, as every year, more and more species become extinct,” Harris stated.

Her analysis focus is to find out which species name Saskatoon residence, and the way they’re utilizing town amid city improvement and near-constant change.

Harris positioned motion-activated cameras at totally different places inside Saskatoon, which captured 21,000 pictures of about 10,000 wildlife appearances from September to December 2021.


The examine is the primary of its variety in Saskatoon to supply a large-scale, year-round platform for monitoring city wildlife. Knowledge collected will likely be used to construct an city wildlife databank for Saskatoon that may function a base to look at traits and patterns in wildlife appearances over time.

The primary batch of pictures recognized 18 species, together with black bears, porcupines, long-tailed weasels, moose, and beavers. Harris stated the most typical species showing inside Saskatoon metropolis limits are white-tailed jackrabbits, crimson foxes, mule deer, and coyotes.


“My preliminary analyses are showing just how vital urban habitat connectivity and wildlife corridors—areas of land that allow an animal to move from one disconnected patch to another—are for wildlife biodiversity, with the least connected sites displaying very low levels of biodiversity,” stated Harris.

“Furthermore, most wildlife species have shifted to behaving primarily nocturnally as a coexistence adaptation for living in densely populated urban areas.”


Harris stated one other fascinating adaptation she has noticed in city settings is “human shielding”—a phenomenon that refers to prey animals remaining in areas with human exercise due to a diminished danger of encountering a predator species.

Her mission will proceed to gather information till late 2023, however Harris hopes the monitoring platform continues to watch Saskatoon’s city wildlife for many years to come back. Her mission is supervised by USask affiliate professor Dr. Ryan Brook (PhD).

“I come from a small northern community, The Pas, Manitoba, where I was raised to value and protect our natural resources and what they provide to us,” stated Harris.

“Most people—myself included before I started this project—are truly unaware of the number of species that we share the city with. So, it’s been incredibly eye-opening and humbling at times, being able to not only discover this other world, but also share it with others.”

The examine was supported by the Pure Sciences and Engineering Analysis Council of Canada and by quite a few accomplice organizations together with USask, the Metropolis of Saskatoon, the Meewasin Valley Authority, Wild About Saskatoon, the Saskatoon Forestry Farm Park and Zoo, Wanuskewin Heritage Park, and the Saskatoon Nature Society.

This article first ran as part of the 2022 Young Innovators series, an initiative of the USask Analysis Profile and Influence workplace in partnership with the Saskatoon StarPhoenix.
