Scientists Just Discovered 5.6 Million Bees Under a New York State Cemetery

Why It Matters

The discovery reveals cemeteries as high‑value pollinator sanctuaries, informing conservation strategies for declining solitary bees. It also provides a benchmark for assessing habitat potential in urban and semi‑urban landscapes.

Key Takeaways

• 5.6 million ground‑nesting bees found at Ithaca cemetery
• Bees occupy 6,500 m², dwarfing typical honeybee colonies
• Study highlights cemeteries as critical pollinator habitats
• Solitary Andrena regularis have persisted since at least 1935
• Researchers estimate 5.56 million bees emerged in spring 2023

Pulse Analysis

Ground‑nesting bees make up roughly 70 percent of U.S. native pollinators, yet they receive far less public attention than their honey‑producing cousins. The Cornell team’s meticulous fieldwork—tracking emergence patterns over a six‑week window—revealed a staggering 5.56 million individuals surfacing from a modest 6,500‑square‑meter plot. By contrast, a typical honeybee hive houses about 30,000 workers, highlighting how a single solitary bee aggregation can dwarf conventional apiary expectations. This scale of abundance suggests that even small, managed green spaces can support massive pollinator populations when conditions align.

Cemeteries, often overlooked in urban ecology, provide a unique blend of undisturbed soil, low pesticide exposure, and diverse floral resources, creating ideal nesting grounds for solitary bees. The East Lawn Cemetery’s long‑standing presence since 1878 has allowed Andrena regularis to establish a multi‑decadal foothold, offering a living laboratory for studying pollinator longevity and habitat stability. Comparative studies—from Arizona’s 1.6 million Centris colonies to Brazil’s modest 13,500 Epicharis—underscore the variability of bee densities across habitats, reinforcing the notion that land‑use history and micro‑climate are decisive factors.

The broader implication for policymakers and land managers is clear: integrating pollinator‑friendly practices into non‑traditional spaces can yield outsized ecological returns. Protecting and enhancing ground‑nesting habitats—through reduced soil compaction, native plantings, and minimal disturbance—could bolster pollination services essential for agriculture and biodiversity. As solitary bees continue to face threats from habitat loss and climate change, the Ithaca cemetery case study offers a compelling template for leveraging existing urban infrastructure to safeguard these indispensable, yet under‑appreciated, pollinators.
