Degree of Threat: C : Not very threatened throughout its range, communities often provide natural resources that when exploited alter the composition and structure over the short-term, or communities are self-protecting because they are unsuitable for other uses
Comments: Local/regional declines were caused by unregulated trapping and degradation of riverine/riparian habitat. Oil contamination resulted in reduced habitat availability in Alaska (Bowyer et al. 1995).
