- Northwestern Pond Turtle has been extirpated in British Columbia with only a few populations known in Washington.
- Terrestrial habitat use for 6 months of the year.
- Preferred aquatic conditions are standing or slow moving water with underwater shelter sites and soft muddy bottoms for burrowing and abundant basking sites.
- Basking is essential for physiological functions.
- During hot periods they estivate under mud or leaf litter to regulate body temperature.
- Juveniles use shallow muddy bottoms while adults use deeper muddy bottoms.
- Most active in aquatic in spring smmer and fall.
- Upland habitat sparse vegetation with exposure to sunlight
- Nesting within 500 m of water in areas with sparse vegetation with no canopy and exposure to sunlight.
- Nestlings emerge march to paril in the following year after a year in the nest.
- Thus require a connected network of related habitat.
- Juvenile mortality has increased from bullfrog and bass.
