Our Response: You will find provided the new commenters’ clarifications towards Record section of brand new preamble to that particular final listing laws. We had been already aware of the brand new Maine, Virginia, and GBIF records and put those data in our SSA analyses.

The Response: Even though empirical research are currently not available regarding your amount of habitat losses and you may destruction impacting the fresh new rusty patched bumble-bee, we do know for sure that environment impacts features brought about refuse of most other Bombus varieties ( e.grams., Goulson et al. 2015, p. 2; Goulson and you will Darvill 2008, pp. 193194; Brownish and you may Paxton 2009, pp. 411412).
