Updating the Black Rock Forest Flora

Christian Liriano

Saturday, June 20th | 9 am – 4 pm

Black Rock Forest in Cornwall, New York is one of the most thoroughly studied and botanically diverse research forests in the Hudson Highlands. This 3,750-acre preserve contains a remarkable range of habitats, including oak-dominated uplands, cool hemlock ravines, rocky ridgetops, reservoirs, and remnant wetlands. Over 700 species of vascular plants have been documented from the Forest, making it an ideal living laboratory for floristic research. On this trip we will conduct a modern update of the vascular flora of Black Rock Forest by attempting to relocate historical records, documenting new occurrences, and searching for rare or overlooked species. 

We will visit as many habitat types as possible to capture the full ecological diversity of the site, from dry hilltops to shaded coves and pond margins. Participants will also apply and test the shade tolerance index for understory plants developed for northeastern North America, evaluating how current field observations compare with published tolerance rankings. 

Expect moderate hiking, occasional off-trail botanizing through shrubs and dense vegetation, and the possibility of encountering ticks. Be sure to bring a lunch, water, and sturdy footwear.  And don’t forget your favorite plant identification book.
