The USGS researches land use and honey bee health in the northern Great Plains. This research will be useful in equipping land managers and policy makers with the best-available science to improve forage and habitat for pollinators in a part of the country that is undergoing rapid land-use change.

Honey bees live and work in highly collaborative, social colonies with a sole reproducing queen, and they make honey by storing nectar from flowering plants in their hives for use during food scarcities.

Great Blue Herons are found throughout much of North America, but are always associated with water. Because they fish by sight, they need relatively shallow water. Release of too much water through the canals north of the Everglades can interfere with their ability to find food.
