Objective 1: Trail Delineation
In order to facilitate public access to the preserves, trail guides were produced such as in the following Dam Pond Maritime Reserve example. Trails were delineated by walking them with a sub-meter resolution GPS, and overlaying the data on aerial photopraphs. The locations of additional features such as information kiosks or points of interest (e.g., osprey nest) were also incorporated. This information was used to create highly accurate trail maps, which are posted at the trail head, on the Town's website, and on brochures.
 

Objective 2: Habitat Delineation
An inventory of natural resources was conducted for both educational outreach and habitat management purposes. By studying aerial photographs, the boundaries of different vegetative habitats were estimated and incorporated into the database. These boundaries were subsequently verified through field observations. The below figure shows the 4 distinct habitats present in Dam Pond Maritime Reserve.
 

Incorporating multiple sets of information (trail maps, aerial photographs, habitat types, natural resources) into a GIS database has many advantages. For example, it can be used by Town planners to create and maintain trails, or it can be used to create maps or brochures which will assist the public in enjoying the open space. The information can also be used in an effort to monitor natural resources over time, as well as determine any needs for restoration. Regardless of the particular application, GIS can be a valuable tool for in managing and protecting open space.
