EXPERIENCE: 
As a plant ecologist Ms. Gadwa inventories, assesses, photographs, and 
monitors ecological communities, often in support of open space 
acquisition initiatives. She plans & guides control programs for invasive 
plants, and searches for listed plant and turtle populations and assesses 
their habitat. Botanical specialties include vascular plant identification and 
winter botany. As a wetland and soil scientist, she assesses functions & 
values, delineates wetland and watercourse jurisdictional boundaries (CT 
and U.S. Army Corps of Engineers), plans & supervises wetland 
mitigation and restoration.  She performs vernal pool studies, water quality 
testing and data analysis, and in-stream bio-assessments. Her effective 
third-party reviews of development projects draw on this expertise.
