Native Plants of the Sligo Creek Watershed

This compilation of the native plants of the Sligo Creek Watershed is the most current and comprehensive flora of our watershed. We will be updating this list as new discoveries are made. Field observation and judgment inform the rankings in the 'occurrence' column and the location description in the 'habitat' column. The comments in the 'remarks' column provide key descriptive features to aid in plant identification. The botanical sequence and nomenclature follows Russell G. Brown and Melvin L. Brown, Woody Plants of Maryland, 1972, Port City Press, Baltimore, MD.

It is our sincere wish that this woody flora helps to increase people's awareness and appreciation of the native plants and habitats of the Sligo Watershed, leading to their conservation and restoration.
