Samara Kolasko, M.Sc., B.I.T. | Junior Biologist

Samara is a Junior Biologist at SCL. She has 6 years of experience in resource and land management with a background in wildlife restoration and terrestrial ecosystems. British Columbia born and raised, Samara has lived across the province from the north, southern interior, to the south coast, exposing her to a diverse set of ecosystems that constantly challenge her to learn. Prior to joining SCL, Samara has experience working for both environmental non-profits and governmental agencies. Most recently, she worked for Ducks Unlimited Canada with her role focusing on wetland assessments, predictive mapping, and monitoring marsh recession in Richmond and Delta’s foreshore habitats.

Samara graduated with a B.Sc. in Environmental Science from the University of Northern British Columbia and an M.Sc. in Ecological Restoration at Simon Fraser University. Her master’s thesis focused on at-risk raptor species restoration via habitat creation by monitoring prey response to vegetation and soil conditions. This research provided a set of recommendations and restoration techniques to improve prey abundance, and thus at-risk raptors, in BC’s Lower Mainland.

When not at work, you can find Samara by the water or in the mountains hiking, dirt-biking, snowboarding, or hanging out with her dog, Clover. She has also recently joined the Board of Directors for the Fish and Wildlife Compensation Program.
