Creating Suitable Habitats for Bees and Promoting Native Plant Species

Honey bees have received a lot of attention in the media lately, and their decline is a great cause of concern for agriculturists, beekeepers, and the pollinator dependent environment at large. However, native pollinators such as butterflies, birds, bats, native bee species, and other insects are at risk from pesticide usage and a decline in suitable habitat as well. There are more than 4,000 species of bees native to North America, with over 300 found in Pennsylvania. Unlike honey bees, which are found predominantly in managed bee houses, most bee species live in the ground, or in dead wood, and crevices between rocks.

Guidelines for providing natural, native bee nesting sites. Different native bee species will utilize different habitat types, and a variety of possibilities should be offered to attract a variety of bees.

  • Small areas of bare ground surrounded by weedy vegetation
  • Well drained soil on flat or sloping surfaces
  • Dry, dead wood with holes from beetles or other burrowing species
  • mounds of sandy soil
  • well drained soil protected by loose networks of sticks and brush
  • all nesting areas should be within range of foraging habitat (native flowering plants)

Some bee species that tend to be more colonial than solitary, like some bumblebee species, will also inhabit home-made bee boxes.

The Xerces Society offers a number of guidelines for maintaining and creating your own nesting sites in this fact sheet: Nests for Native Bees
Pollinator Friendly Lawns

Lush green lawns consisting of just one species of turf grass may look great to humans, but they offer little or no benefit to most bee species. Bare spots encourage nesting habitats for ground dwelling bees, and the flowerless lawn does not provide much of a food source for any bee species.

Some tips for making your lawn more pollinator friendly:

  • Use mixed grass seeds with species such as clover, trefoil, and other low growing, flowering ground cover
  • Eliminate use of conventional grub and insect control chemicals such as pyrethroids and imidacloprid (see the active ingredients in your pesticides and fertilizers!)
  • allow flowering weeds to flourish (they cover your lawn just as well as turf grass does)
  • keep some areas “low traffic” to minimize disruption of ground nesting bees

Native Perennial Flowering Species

In addition to adding clover and other low growing plants to lawns, another solution is to cut back on your lawn area altogether. Native flowering plant species are an excellent source of nourishment and habitat for pollinators and other native insects that can keep pests at bay, and trading some lawn area or exotic flowers for a bed of native perennials can provide greater aesthetic and ecological value to your property.

Planting native species helps to ensure that your work will not go to waste, as they are well adapted to the conditions in your area. Most bee populations have evolved with the native flora, and sometimes one plant species is dependent almost exclusively on a certain bee species, and vice versa.

✝ The USDA-NRCS plants database lists Crisium discolor, a native field thistle, as potentially weedy or invasive. Though you should not encourage large populations, it is a valuable pollinator foraging resource and can be managed as such. Its seeds are not commercially available.
