Western Painted Turtle (Chrysemys picta bellii) has a wide distribution in western North America, including western Canada south of the 51st parallel. In British Columbia, there are two populations: Intermountain - Rocky Mountain Population in the southern interior and Pacific Coast Population in the southwest. The coastal population is found in the Lower Fraser Valley and Sunshine Coast on the mainland and on Vancouver Island and some of the Gulf Islands in the Strait of Georgia. The distribution of the Pacific Coast Population overlaps with the relatively densely populated and highly modified southwestern part of British Columbia, where urban development, drainage of wetlands, forestry, road building, and other human activities threaten turtle populations.
The Western Painted Turtle requires wetland habitats for foraging and hibernation and suitable warm sites on land for egg-laying. Egg-laying habitats are often in short supply and a limiting factor for this species and other freshwater turtles.
How to Identify the Western Painted Turtle
Status in Canada
The Pacific Coast Population of the Western Painted Turtle (Chrysemys picta bellii) was listed as endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC)in 2006. The status was reassessed as Threatened by COSEWIC in November 2016. While threats from habitat loss and fragmentation from land development and other sources continue, survey efforts over the past decade have increased the known area of occupancy, particularly on Vancouver Island and the Sunshine Coast. This population is on Schedule 1 of the Canada Species at Risk Act. It is also on the provincial Red List of species at risk in B.C. The Intermountain - Rocky Mountain Population of the Western Painted Turtle is listed as Special Concern in Canada and is on the provincial Blue List in B.C.
See the COSEWIC Status report for more information.

Research & Survey Methods
Example of hand capturing turtles by snorkeling
Since 2010, blood and carapace samples have being collected from Western Painted Turtles across BC by researchers. The ideal sample size per site is 20 or more turtles. These samples are used in a population genetic study at the University of British Columbia Okanagan to determine the genetic status of Western Painted Turtle populations in BC.
The specific goals of this project are:
• to determine the genetic relatedness among Western Painted Turtles in BC to determine their status as conservation units,
• to determine origin and relatedness at the site level for the Pacific Coastal populations,
• to determine whether genetic introgression from other non-native subspecies of Painted Turtle is a threat to Western Painted Turtle genetic diversity
The work has resulted in a Master of Science dissertation by Evelyn Jensen (2011), who found that there are six discrete genetic units or subpopulations of Western Painted Turtle populations in British Columbia (samples from 604 individual turtles were analysed) in the following areas: Sunshine Coast, south coast (southern Vancouver Island and Lower Mainland), Cariboo, Thompson-Okanagan, and Kootenay. Her work indicates that while the turtles dispersed into BC relatively recently (in evolutionary time) from southern refuges after the last Pleistocene glaciation, about 12,000 years ago, considerable differentiation has occurred over the past 700 generation in different regions.

Guidelines for Forestry Lands

Guidelines for Landowners in Residential Areas
Turtles sustain several kinds of injuries from predation, propellers, and grumpy males that allegedly will bite off the tip of the female’s tail.

Non-native Turtles found in BC:
- Red-eared Slider
- Yellow-bellied Slider
- Cumberland Slider
- Reeves Pond Turtle
- Spiny Softshell Turtle
- Common Snapping Turtle
Look out for rare pet trade turtles in our ponds and wetlands as well.
