Climate vulnerability

Sensitivity to climate change


Beller's ground beetles inhabit sphagnum bogs or sphagnum moss in other wet areas (e.g., near springs), preferring the wettest sites available. This species' sensitivity to climate change will largely be driven by shifts in habitat availability. Reduced water availability and quality (i.e., due to precipitation shifts, reduced snowpack, earlier snowmelt) can affect bog water levels, seasonal bog duration, and rates of succession to meadow or other adjacent vegetation, potentially reducing or degrading habitat for this beetle. This species is likely sensitive to both bog drying and prolonged inundation from flooding. Without flight capabilities, this species has limited ability to move in response to climate change (i.e., refugia would have to be contiguous and accessible by ground). Warmer temperatures may increase beetle activity; Beller's ground beetles have historically been found in highest numbers during hot periods.

Confidence: Moderate

Exposure to climate change


  • Changes in precipitation (snow and rain)
  • Increased amount and/or duration of flooding
  • Drought

This species is identified as a Species of Greatest Conservation Need (SGCN) under the State Wildlife Action Plan (SWAP). SGCN-classified species include both those with and without legal protection status under the Federal or State Endangered Species programs, as well as game species with low populations. The WDFW SWAP is part of a nationwide effort by all 50 states and five U.S. territories to develop conservation action plans for fish, wildlife and their natural habitats—identifying opportunities for species' recovery before they are imperiled and more limited.
This species is identified as a Priority Species under WDFW's Priority Habitat and Species Program. Priority species require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. The PHS program is the agency's main means of sharing fish and wildlife information with local governments, landowners, and others who use it to protect priority habitats for land use planning.
