Notes

• Columbia Torrent Salamander and Cascade are under review under ESA by USFWS
• Found in Coast Range and Cascade Range on the Oregon Washington border.
• Family only occurs in Pacific Northwest, inclding Olympic and Southern.
• Highly aquatic species. Eggs and larvae are entirely aquatic, and adults are semiaquatic and have been observed in riparian and upland forest, and may disperse over ridgelines (if moist cool habitats are available).
• Shallow and slow moving parts of first to third order streams, seep wetlands, and spray zones of waterfalls.
• Cool water temperature (>=14 deg c), high water quality low sediment and high oxygen, stream substrate heterogeneity (coarse organic and inorganic substrate), and low flow velocity.
• Affected by loss of canopy cover, wildfire, severe heat and drought, and roads and culverts can present a dispersal barrier, and increase sedimentation, and so Climate Change is likely to affect populations.
• Habitat fragmentation can affect genetic dispersal.
• Eggs can take 9 months to mature, and maturation may take years.
• These species will inhabit lower elevation Lowland Watershed sites as long as habitat is suitable.
• There is a small community of experts working on this species, including Lindsey Thurman (USGS), Dede Olson (USFS Research Station), and Chris Cousins (OSU Graduate Student in 2024)

particles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment.
