As land-use patterns change over time, some pollinating insects continue to decline both in abundance and diversity. This is due, in part, to reductions in floral resources that provide sufficient nectar and pollen.

Despite the importance of bees, there is a gap in the public's understanding of them.

The Red List of US Oaks report details for the first time the distributions, population trends, and threats facing all 91 native oak species in the U.S.

Oak decline is a slow-acting disease complex that involves the interaction of biotic and abiotic factors such as climate, site quality and advancing tree age.

Urbanization is a large driver of biodiversity globally.

The history of the Morris Arboretum can be told through its eldest trees. Every scar and abnormality present on these immense specimens inspire awe, enrich visitor experience, and provide a glimpse into the past of the gardens.

Trees planted in cities face many survival challenges, but when they thrive they make our cities healthier, less hot, and more beautiful.

This project offers a blueprint for the ideal level of maintenance needed to keep this area of the garden aesthetically pleasing and well -kept into the future.

An Urban Tree Canopy (UTC) assessment, which provides a measure of a community’s tree canopy cover, is important for understanding the extent of a community’s forest or tree resource.

Oaks are critical to the health and function of forest and shrubland habitats in the United States, but many native oaks are threatened with extinction in the wild.
