Sonora skipper (Polites sonora) COSEWIC assessment and status report: chapter 8

Limiting Factors and Threats

The most significant limiting factor for the Sonora Skipper is the limited availability of moist, open grassy areas in a landscape that consists primarily of closed canopy coniferous forest. What little grassland exists is predominantly too arid for Sonora Skippers. Plausible threats to Sonora Skipper habitat are intense livestock grazing, natural succession of open areas to closed canopy forests, road construction, and aging of forestry plantations to a closed canopy. Wildfires or controlled burns, although likely to increase habitat availability, may also be a threat to existing populations.
