Development of Wetland Assessment Protocols in New York

Project Sponsor: US Environmental Protection Agency - Region 2 Wetland Program
End Date: March 31, 2016


Developing NYS’ first three-tiered protocol for assessing wetland condition including the first publication of our NY Rapid Assessment Method (NYRAM).

Wetland ecosystem services such as stormwater management, water quality, and water security, are a function of wetland condition. This project addresses the absence of monitoring protocols for freshwater wetlands in New York State (NYS), a need identified in the New York State Water Quality Monitoring Program Strategy 2005-2014 (June 2006). Our objectives were to: 1) assess the condition of NYS wetlands using a three-level sampling approach, and 2) develop a Rapid Assessment Method (RAM) that effectively quantifies wetland condition ("Level 2"). To assess the condition of NYS wetlands remotely ("Level 1"), we developed a statewide Landscape Condition Assessment (LCA) model that cumulatively depicts anthropogenic stressors across the New York landscape (30 x 30-m resolution). Rapid assessment methods developed for Level 2 quantified anthropogenic stressors using basic air photo interpretation and field surveys. At the finest scale of measurement ("Level 3"), plot arrays captured vegetation structure and floristic biodiversity. To create an effective but relatively simple Level 2 protocol that could easily be used by others throughout New York, we used partner feedback and data from Levels 1 and 3 to test, refine, and support the Level 2 rapid assessment method ("NYRAM"). The end result is a set of robust wetland assessment protocols using a three-level sampling design. This flexible method allows practitioners to select the level of sampling that is most applicable to their project goals and resources.
