It includes species occurring in Maryland that are on the federal list of Endangered and Threatened Wildlife and Plants under the Endangered Species Act (ESA), species currently on the State’s Threatened and Endangered Species list, and additional species that are considered rare or under assessment by the Wildlife and Heritage Service.
Compiled by Wildlife and Heritage Service staff and conservation partners, this list of rare species is a result of more than 35 years of effort to gather, research, and analyze data from numerous sources, such as herbaria, scientific literature, unpublished documents, reports from botanists and amateur naturalists, and extensive field work conducted by
scientists from the Department of Natural Resources (DNR).
