Research Spotlight: Biodiversity in the Solar Pollinator Meadow
The Horticulture team planted the Solar Array Pollinator Meadow to provide a habitat for a wide variety of insects, birds, and other pollinators under and around the Weld Hill solar panels. But until recently, they had no good way of knowing just how well their experiment was working–that is, until naturalist Louise Miller took it on as a research project for her Mass Audubon Field Certification. Miller conducted a biodiversity survey of the meadow and recorded 70 species of plants and nearly 300 species of non-plant creatures, from snails and mushrooms to insects and salamanders. Join Miller to learn about the diversity she found here, view some of her incredible photographs, and get a chance to record some observations yourself.

Legacies in the Landscape
Celebrating Hu Xiansu
Hu Xiansu (H. H. Hu), a pioneering botanist who laid the foundation for modern plant taxonomy in China, earned his doctorate at Harvard 100 years ago. His groundbreaking identification of the “living fossil” dawn redwood and leadership in creating China’s botanical institutions cemented his legacy as one of the most influential figures in 20th-century botany.

Maple-leaf Oak
At the southern tip of the Arboretum stands the oldest maple-leaf oak in cultivation.
Pecan
This pecan, collected in 1882, arrived from the first large research project undertaken at the Arnold Arboretum—a nationwide survey of trees and forests for the United States census in 1880. The collector was an ornithologist with an acute eye for detail.
