Pollinators play an important role in natural ecosystems and agriculture, but several species continue to face serious decline. A revised publication from North Dakota State University Extension focuses on why some insect pollinators are threatened and what people can do to help protect them.
The guide highlights four rare pollinators found in North Dakota and outlines the major causes behind their decreasing numbers.
The decline of many pollinators is linked to several common issues. Habitat loss is one of the leading causes, as native grasslands and wildflower areas shrink due to development and land-use changes.
Pesticides also harm pollinator health, especially when used without proper timing or management. Climate change, disease, and reduced food sources add more pressure to these vulnerable species.
The publication features four poorly known but important pollinators. The rusty patched bumble bee is one of the most endangered bees in North America. Once widespread, it now survives in only a few remaining areas. The yellow-banded bumble bee, another native species, has declined sharply due to landscape changes and reduced flowering plants.
Two rare butterflies receive attention as well. The poweshiek skipperling is critically endangered and depends on high-quality prairie habitat, which has nearly disappeared. The Dakota skipper faces similar challenges and now occupies only a small number of prairie locations.
To support these at-risk pollinators, the publication encourages several simple actions. Planting native flowers, limiting pesticide use, and preserving natural habitats help protect rare and common pollinator species. Creating wildflower patches, avoiding mowing during bloom periods, and participating in conservation programs also make a meaningful difference.
The publication is written by a team of experts from North Dakota State University and Michigan State University. Their goal is to help farmers, landowners, gardeners, and communities understand the importance of pollinator conservation and take steps to protect these threatened insects.
Overall, the guide reinforces how pollinators support biodiversity, crop production, and healthy landscapes throughout North Dakota.
