The species is not listed or protected by New York State.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.

Did you know?
If you are passionate about conserving these beneficial insects, you can get involved with groups such as Xerces Society for Invertebrate Conservation and Bumble Bee Watch. You can help on your own property by planting native flowers rich in pollen and nectar and by supporting organic gardening practices (Williams et al. 2014.)

State Ranking Justification [-]
There is a single record from central NY post-2000 as well as the 1990s (Richardson 2013 and Yanega 2013). The species was previously primarily known from the Adirondacks, although there are no records from there since 1980 despite sampling effort. Vermont survey efforts in 2012 suggest this species could be stable to slightly increasing in this neighboring state (Vermont Center for Ecostudies 2013); however, it appears to never have been a common species in NY and the limited data suggest a strong decline. Its decline has been attributed mainly to threats such as habitat loss, pesticides, and urbanization (Schweitzer et al. 2012) as well as pollution and invasive species. It does not appear to be experiencing high susceptiblity to the N. bombi pathogen as with Bombus and Thoracobomus sub-genera.
