According to our analysis, this North American species has not experienced serious declines in relative abundance, persistence, or range in recent years (Hatfield et al. 2014). This finding is consistent with other studies that have found this species to be relatively stable, both regionally and rangewide (e.g. Colla et al. 2012, Colla and Packer 2008, Grixti et al. 2009). Based on the above calculations and trends, along with published reports of bumble bee decline and the assessors` best professional judgement, we recommend this species for the Least Concern Red List category at this time.
