PROVIDENCE — For environmental advocates, the buzz isn’t coming from the bees, it’s coming from them.

Environment Rhode Island, an environmental research and advocacy group, has launched a statewide canvassing campaign to increase awareness of what policymakers could do to protect pollinators.

It’s no secret, even in Rhode Island, that pollinator species — insects such as bees and butterflies — are on the decline, thanks to the climate crisis, habitat loss, and a lack of food sources. For example, historically Rhode Island is home to 11 different species of bumblebee, but state environmental scientists can now only find six.

The state has taken at least one step to address the problem. In 2022 the General Assembly passed a law banning the consumer sale of neonicotinoids, also known as neonics, a class of insecticides that is deadly to pollinators, but especially toxic to bees. Environment Rhode Island says the state should be doing more.

“Plant seeds sold in Rhode Island are coated in neonicotinoids,” Rex Wilmouth, director of Environment Rhode Island, said. “Those chemicals then become part of the plant itself, and infect bees and other pollinators, ultimately killing them.”

Wilmouth said his group was seeking greater restrictions on neonicotinoids, aiming to restrict their coating on plant seeds, and block the chemicals’ use in state wildlife areas and other public lands owned by Rhode Island.

As part of the effort to get the word out about these insecticides, Environment Rhode Island is paying six youth canvassers this summer to door knock on homes and inform residents about declining bee populations, the dangers of neonics, and the benefits of planting native species and pollinator gardens. Canvassers have already door knocked in Providence, Cranston, Warwick, and Barrington.

Eleven other states have similar bans on neonicotinoids in consumer products, but only two other states, Vermont and New York, have banned the neonic coating on commercially available plant seeds.

Repeated and widespread use of neonicotinoids has a serious impact on the environment beyond pollinators. A study by the University of Minnesota published last fall found that consistent application of neonicotinoids for agriculture or insect control was leading to contamination of natural springs and other water sources in Minnesota, and individuals relying on shallow groundwater or springs had a higher risk of contamination than those relying on deeper sources.

Wilmouth noted the state needs to do more than ban bee-killing insecticides. He said it needs to use the public lands it owns to expand pollinator-friendly habitats, and plant more pollinator-friendly vegetation along state roads and highways.

“As I talk to my constituents, more and more of them are starting to recognize the importance of pollinators,” Rep. Michelle McGaw, D-Portsmouth, said.

Earlier this year, McGaw introduced a bill (H5099) that would have empowered and mandated the state Department of Transportation to plant pollinator-friendly native species of trees, shrubs, grasses, and other vegetation alongside state-owned and maintained roads. The bill had no companion legislation in the Senate, and failed to escape committee.

“Passing the bill would be a positive step towards supporting our ecosystem and beautifying our highways,” McGaw said.

Planting alongside state roads has a lot of potential. RIDOT is responsible for 1,100 miles of highway, and another 1,201 of bridges, including large portions of the land next to the roads. The current status for thousands of these highway miles throughout Rhode Island is primarily grass, which gets routinely mowed.

What did RIDOT think of McGaw’s bill? The department didn’t oppose it per se, but director Peter Alviti wrote a letter to the House Environment and Natural Resources Committee in February, saying, “the bill, as it currently reads, requires RIDOT to build this associated cost into the project, impacting the overall time to execute the project, as well as the associated costs. The Department would prefer the language reflect our position to have the option, or choice to implement pollinator plantings when advisable and or appropriate.”

McGaw said changing the bill would effectively keep the status quo in place, where RIDOT plants few pollinator-friendly vegetation. The department’s landscape architecture unit has an ongoing partnership with University of Rhode Island professor Rebecca Brown for installing native plantings along Interstate 95, according to the DOT website.

An added bonus for the state if it implemented pollinator gardens? Less maintenance and less costs for RIDOT and the Department of Environmental Management. Pollinator gardens work best when they are largely left untouched and un-mowed, to allow flowers and other plantings to bloom and attract pollinators.

Reducing mowing to only a few times a year to support pollinator gardens and pollinators would be a big cost savings, according to McGaw.

“It decreases the cost of fertilizers, it decreases the cost of pesticides, it reduces the need for mowing by reducing it to only once or twice a year,” she said. “Rhode Island has a lot of state roads and highways where it could decrease the cost of their maintenance.”

McGaw said she expects to reintroduce her pollinators legislation again next year.
