COSEWIC assessment and status report on the northern rubber boa, Charina bottae, in Canada . : CW69-14/320-2016E-PDF
"This species is patchily distributed within the southern half of British Columbia with concentrations in arid river valleys in the southern interior of the province. The species’ life history traits, including low reproductive rate, delayed age at maturity, and longevity, and specific habitat requirements for hibernation and thermoregulation make it sensitive to human activities. There are inferred declines in mature individuals based on habitat trends, and some subpopulations continue to be threatened by habitat loss and fragmentation mainly from housing developments, roads, and transport corridors. Theoverall threat impact on the Canadian population is deemed to be low; however, the species could become Threatened if threats to local populations are not sufficiently managed and mitigated"--Reason for designation, p. iii.
