MICHELLE STANLEY, Stewardship Technician

Michelle has called the Okanagan home for most of her life which has fostered her passion for wildlife and preserving local habitats. In addition to working for Stewardship, Michelle has volunteered with the Burrowing Owl Society, SORCO Raptor Rehab Centre and the Kamloops Wildlife Park and currently also works for the Osoyoos Desert Society doing habitat conservation, restoration and education. Now residing in the Joe Rich area of Kelowna, she is excited to work as the Stewardship Technician for the North Okanagan.

Michelle is currently on maternity leave.


NORA the GOPHERSNAKE, Species Ambassador

Nora is the newest addition to the OSS team.  She is the Sonoran subspecies of nonvenomous Gophersnake (Pitouphus catenifer), and a close cousin to the smaller Great Basin subspecies of Gophersnake found throughout BC, Nora arrived at the OSS office from the Kamloops Wildlife Park in 2019 after she was confiscated from an individual who did not have proper exotic animal permits.

When she is not participating in OSS's SnakeSmart program or attending other OSS presentations to help reduce fear and misunderstandings around snakes, Nora can  usually be found basking under her heat lamp, dozing under her favourite piece of bark or eating a freshly thawed rat.


​Dianne Bersea, Chair

Dianne is defined by her deep affinity for nature and the creative process. Simply put, she’s a nature nut and a full time observer of her world. Everything interests her… unusual light, dark clouds, strong colours, odd juxtapositions, bird behaviour.  Dianne mines artistic knowledge from careers in graphic design, fine art, natural history illustration, and exhibit design. She is also an accomplished arts instructor and public speaker. A recent addition - she writes a monthly Nature Wise column in Penticton Western News.

Following eighteen years on Cortes Island in BC’s Northern Gulf Islands, Dianne has logged eight years (seven on a 1500-acre ranch) in the South Okanagan. Known for her painterly interpretations of the Canadian west coast and Interior landscapes, Dianne is now making an almost daily practice of nature photography. She has done freelance self-employment as an illustrator / fine artist her whole life.

Jennifer Miles, Vice Chair

While originally from Summerland, Jennifer has lived throughout the Okanagan and currently calls Kelowna home. When not enjoying a good OSS weed pull, Jennifer works for the City of Kelowna enforcing environmental protection regulations in relation to new development. She holds a Bachelor of Science from Simon Fraser University and Master’s degree in Environmental Design from the University of Calgary.  One of her fondest undergrad memories is of a field school course she took in Oliver on understanding the complex interactions within the ponderosa pine forests and grasslands between the plants, wildfire, and animals (specifically Lewis’ Woodpecker, a blue listed species). Jennifer shares her home with her husband, Robert, and children Emily and Benjamin. 

Jill Bisaro, Secretary-Treasurer

Jill grew up in the West Kootenays and always had an interest in biology and conservation. She pursued a technical diploma in Recreation, Fish and Wildlife at Selkirk College, followed by a Bachelor of Science in Wildlife and Fisheries at the University of Northern BC. In the summer of 2016, Jill worked as a Stewardship Assistant with OSS betweem semesters at university, and then again after graduating from her degree in 2019. During these summers, she fell in love with the biodiversity of the Okanagan Valley as well as the stewardship efforts that are being undertaken by OSS.
After completing a research position with the Ministry of Forests, Lands, Natural Resource Operations and Rural Development, Jill has now settled in Vernon and is a Junior Biologist with Western Water Associates, a small aquatic resource-based environmental consulting company.

Margaret Holm, Director
Margaret Holm has twenty-five year experience working on conservation outreach and education in the Okanagan. She lead agricultural extension and EcoStudies programs for the Okanagan Similkameen Conservation Alliance, and has managed outreach and communication for the Community Bat Program, South Okanagan Similkameen Conservation Program, and the Nk’Mip Desert Cultural Centre.

Amanda J Miller, Director, P.Ag.

Amanda is passionate about stewardship and conservation, with a keen interest in providing ecological tools and strategies for long term sustainable land management. Applied science, extension, and effective communication with stakeholders and land managers are key areas of interest. Amanda has a master’s degree in Rangeland and Wildlife Resources from the University of Alberta and has been a professional agrologist since 2016.  As a rangeland specialist for the Government of Alberta from 2013-2019 she worked to develop ecological tools, applied research, and policy to address emerging rangeland issues, and was a rangeland representative on the MULTISAR Steering Committee. The owner and founder of Palouse Rangeland Consulting, Amanda works largely with the BC Cattlemen’s Association, and is a supporter of sustainable beef and cattle as a conservation tool. In her free time, you can find her exploring the mountains by foot, on skis, or horseback.

Melanie Pieorecky, Director


Related to conservation and ecology, Melanie is happy to wear her vegetation ecologist hat, and applying that to restoration planning. She is passionate about working towards shared multiple land uses. Through collaboration she works to understand what those uses are, then figure out out best way to support them. This has been possible through her work as an environmental consultant, which began in 2000. Prior to that she worked for the Ministry of Forests as a rangeland manger in the Bulkley-Cassiar. Through her consulting and volunteer work she has specialized in vegetation ecology, botany for rare plant surveys, soil science, agricultural land use, reclamation and restoration planning, beneficial use of organics and climate change implications to project planning. Her consulting work is driven by regulatory requirements, but Melanie capitalizes on opportunities to collaborate between groups for the benefit of all land users, including wildlife!
