This summer, ecologist Molly Jacobson from the SUNY College of Environmental Science and Forestry made an exciting discovery in Syracuse, New York. While collecting samples in the college’s orchard, she found a chestnut mining bee, a species rare enough to have not been seen in the area for over a century.
Chestnut mining bees are unique insects that mainly pollinate chestnut and chinquapin flowers. Historically, they thrived in New York until the early 1900s, when a chestnut blight devastated the local chestnut trees. This blight led to a decline in the native bee population, causing many to believe these bees might be extinct.
Before Jacobson’s recent sightings, the last recorded sighting of a chestnut mining bee in New York was in 1904. For more than a hundred years, they were absent. However, in 2023, Jacobson saw them again at the Lasdon Park and Arboretum, marking a notable comeback. Surprisingly, just two years later, she spotted them again about 200 miles north in Syracuse. This was the first occurrence of this bee species north of the Hudson Valley.
Jacobson remarked, “This is a significant record. It expands the known range of the bee in New York and shows promise for its persistence in managed orchards, even in urban settings like Syracuse.” This finding is exciting for ecologists, suggesting that conservation efforts might be helping these species return.
The SUNY College of Environmental Science and Forestry has been actively working on a chestnut restoration project. Their goal is to plant new chestnut trees, which might attract these essential pollinators back to the area. The recent bee discovery validates their hard work.
According to recent studies, biodiversity loss is a growing concern worldwide. Pollinators like bees play a crucial role in our ecosystems, strengthening food production and sustaining plant diversity. A report by the United Nations estimates that over 75% of the world’s crops depend on animal pollination, highlighting the importance of preserving species like the chestnut mining bee.
The reappearance of this bee suggests that careful management and restoration efforts can yield positive results. It’s a reminder of how vital it is to protect our environment for future generations.
As Jacobson’s discovery circulates online, many people are expressing joy and hope, perhaps inspired to take part in local conservation efforts. This tiny bee, once thought lost, is a beacon of resilience amid the ongoing challenge of biodiversity decline.
