What practical action supports B. bohemicus habitat indirectly by securing host nesting substrate?
Answer
Maintaining un-tilled, undisturbed ground areas adjacent to forage patches
Effective local habitat creation for the Gypsy Cuckoo Bumble Bee must focus on supporting its hosts, which means securing their nesting sites. Since hosts commonly use abandoned rodent burrows underground, the most effective practical management strategy is maintaining areas where soil structure remains intact and undisturbed by human activity. This includes leaving unmowed strips at field edges or allowing sections of lawn to grow long. Such practices directly increase the availability of secure, subterranean nesting substrate for species like *B. impatiens*, which in turn supports the density required for parasitic success.
