As summer begins, fields, forests, prairies, riverwalks and gardens across Wisconsin come alive with an array of life. Preserving biodiversity in the Badger State is a multi-faceted effort, merging legislative efforts with organized social gatherings to find creative solutions. 

Late last week, a package of bills was introduced to help shore up protections for pollinators. The package of seven bills has a range of policy objectives including:

• Requiring state agencies and government entities to give preference to use native prairie and forage plants to benefit pollinators. 
• Designating June 2025 as Pollinator Awareness Month in Wisconsin. 
• Allowing a political subdivision to regulate pesticides for the purpose of protecting pollinators and pollinator habitats. 
• Prohibiting people who sell plants from advertising or labeling the plants as good for pollinators if they are treated with certain insecticides.
• Establishing a “Protect Pollinators” license plate program, similar to other conservation-focused license plate programs. 
• Prohibiting the DNR from using any insecticide from the neonicotinoid class near any pollinator habitat located on DNR-maintained land. 
• Designating Rusty Patched Bumble Bee as the state native insect and requiring the Wisconsin Blue Book to include information concerning that designation. 

The bills were announced in Menasha by Reps  Lee Snodgrass (D- Appleton) and Vincent Miresse (D- Stevens Point). Luke Schiller, executive director of the Heckrodt Wetland Reserve and Sara Walling, Clean Wisconsin’s water program director, attended the announcement. 

Pollinators are important not only to ecosystems, but also to the global economy. According to an article in Forbes, pollinators contribute between $235 billion and $577 billion in global food production. Pollinators come in all shapes and sizes and include bees, hummingbirds, butterflies and certain species of bats. Decades of overusing pesticides and habitat destruction have contributed to staggering declines in pollinator populations across the globe, and throughout ecosystems. 

The Department of Natural Resources (DNR) is seeking volunteers to monitor one of those pollinators, the Karner blue butterfly. Volunteers have been crucial  in tracking the endangered butterfly since 2018. Although the butterflies are found from Minnesota to Maine to Canada, Wisconsin has the largest remaining population. Karner Blue Butterflies are threatened by habitat loss fragmenting their range into isolated pockets and climate change. Open barrens, savannas and prairies are still abundant in Wisconsin, and are ideal habitats for the butterfly. 

“Volunteers will be able to identify Karner blue butterflies and help us collect data to look at how this species moves around the landscape over time,” Chelsea Weinzinger the DNR’s Karner blue butterfly recovery coordinator said in a statement. “Collecting this information improves our data and gives us a better statewide picture of how this species is faring.” The Karner is related to the northern blue butterfly, which some DNR researchers say they haven’t seen since 2010 in Wisconsin. 

Field trip opportunities are also available through the Natural Resources Foundation of Wisconsin. The field trips occur across the state and range from paddling wetland habitats to joining researchers in Beaver Creek Reserve to learn about the state’s smallest falcon species. Several field trips are also occurring in the Milwaukee-area, offering people the chance to canoe under tree canopies on the Milwaukee River, traverse urban habitats, explore hardwood forests and wetlands in the Mequon Nature Preserve   and much more.
