Survey of Sligo’s Native & Alien Plants of 1971
The “Salisbury List”

Dorothy Salisbury surveyed the flora of Sligo Creek over 25 years. In 1971, the Maryland National Capital Park and Planning Commission published her findings, “The Salisbury List”. She organized the plants into 4 sections: Trees and Shrubs, Ferns and their Allies, Flowering Plants, and Vines. Each section is shown below in a searchable table format.

Along with the lists, the Commission published The Plants of Sligo Creek Park, her extensive notes on Sligo and the Salisbury plant lists.

Key to the Codes in the Notes Column:
N = Native to Sligo Watershed
A = Alien, not native to Maryland; most are not even native to North America
U = Unlikely to be Found in the Sligo Watershed
NC = Native to Coastal Plain of Sligo Watershed
NU = Native to Maryland but highly unlikely to be found in Sligo Watershed
AU = Not native to Maryland AND highly unlikely to be found in Sligo Watershed
MD = Native to Maryland, but not native to Sligo Watershed; planted in Park, NOT Naturalizing
MN = Native to Maryland, but not native to Sligo Watershed; planted in Park and Naturalizing
UN = Not a recognized botanical name. Uncertain as to species.
