PORTLAND, Ore.; Wednesday, September 29, 2021---Responding to a petition to list the American bumble bee (Bombus pensylvanicus) as an endangered species, the US Fish and Wildlife Service (FWS) issued a positive 90-day finding, indicating that the bumble bee may warrant federal protection under the Endangered Species Act (ESA). The 90-day finding initiates a formal review by the FWS, including a Species Status Assessment (SSA). The Center for Biological Diversity and the Bombus Pollinator Association of Law Students of Albany Law School submitted the petition earlier this year.

The American bumble bee, as its name implies, was once broadly distributed across much of the U.S. and has one of the widest ranges of all North American bumble bees, from southern California and the Desert West (including parts of Mexico) through the Great Plains and out to the east coast, from Florida to Canada. However, many studies suggest that the American bumble bee is declining, especially in the northern part of its range. It is listed as Vulnerable on the IUCN Red List

Bumble bees are beneficial and effective pollinators, helping to pollinate not only beautiful wildflowers, but also crops and gardens that provide us with nutritious fruits and vegetables. Sadly, these friendly insects are in decline due to a multitude of issues, including but not limited to, habitat loss, pesticide use, pollution, and mites. The easiest way to help bumble bees is to plant native habitat. — U.S. Forest Service

Virginia Taking Bold Actions to Curb Marine Debris

Virginia Taking Bold Actions to Curb Marine Debris

Trash, from littering, mis-managed trash cans, or uncovered trucks, travels through watersheds via stormwater and ends up in our rivers, bays and ocean. About 60% to 80% comes from our activities on land. A study by the Virginia Aquarium and Clean Virginia Waterways (CVW), funded by the Virginia Coastal Zone Management (CZM) Program at the Virginia Department of Environmental Quality (DEQ), found that 83% of trash on Virginia’s beaches was made of plastic, and most of it was single-use items (bottles, cups, straws, food wrappers).

Migratory Birds Legislation

Virginia adopts new legislation to protect migratory birds

The Department of Wildlife Resources (DWR) announced that the Board of Wildlife Resources adopted new legislation that will protect migratory birds. The rule protects migratory birds from accidental killing, harm and habitat disturbance due to industrial, commercial and construction projects.

new study about effects of pesticides on pollinators

DiBartolomeis, M., et al. (2019). "An assessment of acute insecticide toxicity loading (AITL) of chemical pesticides used on agricultural land in the United States." PLoS ONE 14(8): e0220029.
    We present a method for calculating the Acute Insecticide Toxicity Loading (AITL) on US agricultural lands and surrounding areas and an assessment of the changes in AITL from 1992 through 2014. The AITL method accounts for the total mass of insecticides used in the US, acute toxicity to insects using honey bee contact and oral LD50 as reference values for arthropod toxicity, and the environmental persistence of the pesticides. This screening analysis shows that the types of synthetic insecticides applied to agricultural lands have fundamentally shifted over the last two decades from predominantly organophosphorus and N-methyl carbamate pesticides to a mix dominated by neonicotinoids and pyrethroids. The neonicotinoids are generally applied to US agricultural land at lower application rates per acre; however, they are considerably more toxic to insects and generally persist longer in the environment. We found a 48- and 4-fold increase in AITL from 1992 to 2014 for oral and contact toxicity, respectively. Neonicotinoids are primarily responsible for this increase, representing between 61 to nearly 99 percent of the total toxicity loading in 2014. The crops most responsible for the increase in AITL are corn and soybeans, with particularly large increases in relative soybean contributions to AITL between 2010 and 2014. Oral exposures are of potentially greater concern because of the relatively higher toxicity (low LD50s) and greater likelihood of exposure from residues in pollen, nectar, guttation water, and other environmental media. Using AITL to assess oral toxicity by class of pesticide, the neonicotinoids accounted for nearly 92 percent of total AITL from 1992 to 2014. Chlorpyrifos, the fifth most widely used insecticide during this time contributed just 1.4 percent of total AITL based on oral LD50s. Although we use some simplifying assumptions, our screening analysis demonstrates an increase in pesticide toxicity loading over the past 26 years, which potentially threatens the health of honey bees and other pollinators and may contribute to declines in beneficial insect populations as well as insectivorous birds and other insect consumers.
