Land Management Implications for Hemileuca maia (Lepidoptera: Saturniidae) Habitat at Manuel F. Correllus State Forest, Martha's Vineyard, Massachusetts (Haggerty MS thesis 2006)




Early seral habitats in the northeastern U.S. are being threatened by succession brought on by the alteration of natural ecosystem dynamics (Noss 1995). In fire- dependent systems such as sandplain barrens, this is compounded by the threat of catastrophic fire from increased fuel loads created by long-term fire suppression. Efforts are currently underway in many areas to restore open habitats through the reintroduction of natural disturbances or by alternative techniques which mimic their effects. In fire prone systems, the goal of these efforts is twofold: 1) to reduce fire danger in areas with heavy fuel loads and 2) to restore natural open habitats. The effects of such management on the native insect species, including rare species dependent on open systems, are just beginning to be examined (Swengel 2001, Swengel and Swengel 2001, Panzer and Schwartz 2002).

Distribution of Rare Plants on the Central Plain of Martha's Vineyard: Implications for Conservation and Management (Clarke MS thesis 2006)




Rare plants in coastal New England sandplains are often restricted to sites disturbed by humans. On the central plain of Martha’s Vineyard, which has one of the highest concentrations of rare plant species in Massachusetts, disturbances include plowed and mowed firelanes. Little is known about pre-European rare plant habitat or how modern management impacts these species. To better understand the factors influencing the distribution of rare plants in coastal habitats, I examined the influence of vegetation structure, species composition, environmental characteristics and disturbance history on existing rare plant populations and potential natural habitat in the 2100-ha Manuel F. Correllus State Forest. This was accomplished by sampling more than 100, 100-m2 plots in firelanes (including 22 at rare plant occurrences) and forested/shrubland areas. I also conducted extensive searches for rare species.
