We have advanced knowledge of the diversity, identification, and ecology of rare and common plant species and natural communities of the Northeast. We specialize in surveying state-listed plants, significant natural communities, and invasive plants.

• Survey/inventory of rare and common aquatic, wetland, and upland species of northeastern North America
• Survey/inventory of natural communities in a range of rare and unique habitats such as calcareous fens, bogs, rich mesic forests, subalpine habitats, and cliffs
• Long-term monitoring of populations, habitats, and natural communities
• Sampling protocols and study designs for a variety of species, habitats, and objectives  
• Habitat assessment and mapping (GPS/GIS)
• Development of conservation and management plans 
• Invasive species inventory, mapping, monitoring, and control
• Environmental impact studies pertaining to development, recreation, and rare plant population relocations
• Data analysis, presentation, and reporting

• Rare plant surveys along coastal plain pond shores on Cape Cod
• Invasive plant survey and mapping in the Westfield River watershed in Massachusetts
• Invasive plant mapping and development of an invasive plant management plan for Greylock Glen (Massachusetts)
• Rare plant and natural community survey at Greylock Glen for a proposed outdoor education and recreation facility and trail system
• Rare plant surveys for transmission line corridors in Massachusetts, Vermont, and New Hampshire (see example)
• Rare plant survey for proposed grassland reclamation areas in Adams, Massachusetts
• Rare plant surveys along the Cheshire Harbor and Overlook Trails at Mount Greylock State Reservation
• Tidal wetland survey for a proposed marina along the lower Connecticut River in Connecticut
• Invasive plant survey at Glendale Dam along the Housatonic River in Massachusetts
