Drastic decline in New Hampshire’s bumble bees

Staff Writer |
In the first long-term study of New Hampshire’s bumble bee population, researchers with the New Hampshire Agricultural Experiment Station at the University of New Hampshire have found three of the state’s most important bumble bee species have experienced drastic declines and range constriction over the last 150 years, with a fourth bee also in significant decline.

The research was conducted by Sandra Rehan, experiment station researcher and assistant professor of biological sciences at the University of New Hampshire; Erika Tucker, USDA research fellow and a postdoctoral researcher with the experiment station; Minna Mathiasson, a graduate student in biology; and Molly Jacobson(link is external), a recent graduate of UNH’s undergraduate wildlife and conservation biology program.

The research results are part of the experiment station-funded project Sustainable Solutions to Problems Affecting Bee Health and are presented in Decline of bumble bees in northeastern North America, with special focus on Bombus terricola(link is external),in the journal Biological Conservation.

“Wild bees, particularly bumble bees, are highly important pollinators for both agriculture and unmanaged ecosystems," according to Rehan and her colleagues.

"They have experienced alarming declines in recent decades, and in order to effectively work towards their protection, information about their life histories, ecological roles, and distributional changes on a more local scale is needed."

The value of pollination to agriculture is estimated at more than $200 billion a year worldwide.

The abundance of and diversity of pollinators are declining in many agricultural landscapes across the United States. Given this importance, widespread declines in pollinator diversity have led to concern about a global pollinator crisis.

The National Research Council has called for regional, national, and international monitoring programs to allow tracking the status and trends of pollinators.

To conduct their research, scientists analyzed 3,333 bumble bee specimens comprising 16 Bombus species dating to 1867. Bombus specimens for this study were made available from the UNH Insect Collection(link is external), as well as from field collections performed by the Rehan lab(link is external) during the summers of 2014–2016.

This allowed researchers to track, over time, changes in abundance and distribution, with focus on species designated of greatest conservation need by the N.H. Department of Fish and Game. Floral records also provided insight into the diet breadth of these species, which may affect their vulnerability.

Scientists found drastic decline in Bombus affinis, Bombus fervidus, and Bombus terricola, as well as significant decline in Bombus vagans, with data suggesting it has been ecologically replaced by Bombus impatiens over time.

The rusty patch bumble bee, Bombus affinis, was the first bee listed as an endangered species in the continental United States earlier this year. This species is thought to be locally extinct in New Hampshire, as was last collected in 1993.

Among other species of greatest conservation need, Bombus fervidus has declined by 96 percent over the past 150 years, and Bombus terricola has declined by 71 percent. Bombus vagans has also experienced a significant decline of 42 percent in New Hampshire. The researchers suggest Bombus vagans receive future conservation consideration.

Their analyses also found a severe constriction of the geographic range of Bombus terricola to high elevation regions in the latter half of the 20th century, and its role as pollinator of several alpine plants necessitates immediate conservation action.

The study adds critical floral associations and demographic data for New England bumble bees and those undergoing national decline, to better inform management decisions and conservation efforts going into the future.
