Speaker: William Hilgartner, Ph.D.
This presentation will describe an ongoing study of a serpentine grassland at Bare Hills Barrens, part of the Lake Roland Park near Baltimore, which was begun in 2000. The original purpose was to identify and record all herbaceous species in a 550 square meter plot. Blooming times and the presence/absence of grasses, sedges and other flowering plants have been monitored within that plot since 2000. After 2002 the study became a study of succession and stability, as well as providing insights into the "serpentine factor", the physiological factor(s) that governs why some species persist there while others are precluded. The uniqueness of the vegetation, community stability and change, and the impact of pine expansion and non-natives will be discussed. The webinar will include a description of a restoration site. The Bare Hills name goes back to the 1700s or early 1800s when the first mining of chromium began there in 1810.
