NatureServe Status

Global Status: G4G5
Global Status Last Reviewed: 19Mar2010
Global Status Last Changed: 19Mar2010
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G4 - Apparently Secure
Reasons: This is a moderately widespread bumblebee in a subgenus that is not in general decline. Information found was insufficient to warrant a definitive G5 but this would probably be the rank with better information and is the rank from Rank Calculator version 3.1 as of August, 2012. While it is well known that some bumblebees have crashed drastically or declined, many others, apparently including this subgenus, have not. Notably still being found recently in southern portions of the range like Arizona and Colorado, so probably doing at least as well farther north. Apparently secure. At the northern edge of its range in British Columbia and likely rare.
Nation: United States

NatureServe Global Conservation Status Factors

Range Extent: 200,000 to >2,500,000 square km (about 80,000 to >1,000,000 square miles)
Range Extent Comments: This is a widespread western North American bumblebee. It does not occur on other continents and has a somewhat smaller range than many. It occurs from southern British Columbia to the mountains of Arizona, where Schmidt and Jacobson (2005) found it in five of six mountain ranges. Kearns and Oliveras (2009) found it still extant around Boulder Colorado, also toward the southern end of the range. There are a few records as far east as Wisconsin and Kansas. Five specimens of B. morrisoni were identified in Texas by Beckham and Atkinson (2017); this species had not previously been documented in the list of Texas bumble bee species compiled by Warriner (2012).

Overall Threat Impact: Unknown
Overall Threat Impact Comments: No reports of widespread threats and the subgenus is generally doing well.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: As far as known fairly stable, not on any lists of declining species, nor have any other species in this subgenus been identified as in trouble.

Long-term Trend: Unknown

Environmental Specificity: Broad. Generalist or community with all key requirements common.

Other NatureServe Conservation Status Information

Inventory Needs: As with all bumblebees this one should be monitored.
