Bumble bee added to Vermont’s threatened and endangered list
MONTPELIER — The Vermont Agency of Natural Resources recently added nine species to the list of state threatened and endangered species. The listing included four plants, three bumblebees, one amphibian and one bird.
Three pollinators were listed — the rusty-patched bumblebee, yellow-banded bumblebee, and Ashton cuckoo bumblebee. Pollinators such as bees, moths and butterflies are critically important to Vermont’s agriculture, but many are in decline nationwide. According to a survey by the U.S. Department of Agriculture, beekeepers reported losing 42 percent of their honeybee colonies between April 2014 and April 2015.
Vermont’s bumblebee species appear to be in decline due to a parasite infestation. Another concern for pollinator conservation is the widespread use of a group of systemic insecticides referred to as “neonicotinoids.” These pesticides are used on agricultural crops, and are also used in concentrated doses on home gardens, lawns and ornamental trees. Several types of neonicotinoids are highly toxic to bees, in addition to making them more susceptible to parasites and pathogens. The federal Environmental Protection Agency is currently considering legislation that would limit the use of these chemicals.
“Pollinators are essential to our farms and also to our meadows and wild orchards,” said Deb Markowitz, secretary of the Vermont Agency of Natural Resources. “Adding them to the endangered species list is only one of many steps we can take to help protect them. Additional techniques, such as integrated pest management and planting more native flowering plants, are others.”
The bumblebee listings do not come with restrictions against currently legal activities such as applying pesticides in accordance with state and federal regulations, although the secretary may notify a landowner that a permit is required in cases where one of these bumblebee species is likely present. More information on pollinators, including a list of pesticides for homeowners to avoid, is available on The Xerces Society’s website at www.xerces.org.
In addition to pollinators, the Fowler’s toad and rusty blackbird were listed as endangered in Vermont.
The Fowler’s toad is dependent on scoured sand banks along the Connecticut River, a limited habitat type in Vermont, and has always been extremely rare in Vermont. However, the toad had been detected in the state with infrequent regularity until 2007 when the toad was last heard.
Rusty blackbird populations have declined regionally by more than 90 percent during the past five decades, according to the North American Breeding Bird Survey. Vermont is at the southern edge of the bird’s boreal forest breeding habitat.
Four plant species were also listed as endangered in Vermont. These include the dwarf birch, tulip tree, whorled milkweed, and green mountain quillwort. These plants were previously not thought to exist in the wild in Vermont, but single specimens or single populations of all four species were found recently in the state.
“While we are delighted to have located these rare species, their endangered status reminds us that many of these plants can only survive where there is habitat to support them,” said Markowitz. “We are fortunate in our state that Vermonters value the bees, birds and plants that enrich our experience of nature and have worked to conserve lands so that future generations might enjoy them as well. It is critical that we continue to protect not only endangered species but the places where they thrive.”
Vermont currently has 51 state threatened and endangered animals, and 163 state threatened and endangered plants. Three well-known birds were removed from the list in 2005 — the peregrine falcon, osprey, and common loon — following the birds’ recovery as a result of conservation efforts.
