New! Wetland System Assessment Tools and Reports for New Hampshire.

Draft Classification of Freshwater Lakes & Ponds in New Hampshire. The goals of this report are to: 1) identify and develop a draft lake and pond classification framework directly applicable to waterbodies in New Hampshire; 2) provide a framework for aquatic bed communities associated with different waterbody types; 3) identify where the largest gaps exist in our understanding of the classification; 4) provide ecological context through descriptions, keys, and cross-walking New Hampshire's system and natural community types to NatureServe ecological concepts (where possible), and; 5) propose draft state-level conservation status ranks for each type of lake and pond system in order to inform environmental reviews, as well as regulatory and conservation planning for naturally occurring waterbodies.

Fact Sheets for Wetland Systems in New Hampshire. These wetland system fact sheets include photographs and information on ecology, distribution, stressors, relationships to other classifications, and more.

Rank Specifications for Wetland Systems in New Hampshire. Rank specifications identify the ecological integrity criteria for each type of wetland system in New Hampshire. These criteria provide the guidance that allows wetland scientists to assign ranks to individual wetland systems from excellent (A) to poor (D) integrity. These criteria follow an indicator-based approach, one that emphasizes specific metrics to assess the ecological integrity of wetland systems. For each system, the rank specifications provide guidance specific to EIA metrics, and identify publically accessible reference condition (or least impacted) examples in the state for comparison opportunities. These rank specifications allow a broader audience to repeatedly and objectively apply the EIA method in New Hampshire by using the reference condition system descriptions in this document.

Wetland System Conservation Status Ranks in New Hampshire. Wetland system state conservation status ranks, a series of S-Ranks ranging from S1 to S5 (critically imperiled to secure at the state level), assess extirpation risk for different wetland types in the state. Previously, these conservation status ranks were primarily based on numbers of occurrences, and the rank assignment process was subjective, leading to potential issues with consistency, repeatability, and transparency. Training and review had been used to minimize these issues, but the assessments were nevertheless influenced by personal judgments, perceptions of risk, and systemic biases. A more objective approach has been developed by NatureServe to address these issues. We used the new approach to re-evaluate the conservation status of New Hampshire's 27 wetland system types.

Ecological Integrity Assessment Trainings. The Ecological Integrity Assessment (EIA) Method is a rapid (Level 2), multi-metric, objective, science-based approach for assessing wetland condition. Through this grant, we provided four two-day EIA wetland condition trainings designed to meet the needs of natural resources professionals and community stakeholders. One of the goals of the training was to promote the EIA Method so that it is accessible to a much broader audience. Data on the condition or ecological integrity of wetland systems can be used to aid functional assessments, monitor status and trends, prioritize sites for conservation or restoration, guide mitigation applications, and contribute to land use planning.

Comparison of Alternative Wetland Assessment Methods at Numerous Sites in New Hampshire
.  The principal goal of this project was a comparison of alternative wetland assessment methods. The methods chosen for this study were: The Method for Inventorying and Evaluating Freshwater Wetlands in New Hampshire (NHM), USA RAM, Ecological Integrity Assessment method (EIA), and Floristic Quality Assessment (FQA). 54 pages.

Comparison of Alternative Wetland Assessment Methods at Five Restoration Sites in New Hampshire.  The principal goal of this project was to compare alternative wetland assessment methods at three to five restoration projects, focusing on the overall condition of wetlands at mature restoration or constructed mitigation sites. Better understanding the strengths and weaknesses of alternative wetland assessment methods will allow regulatory agencies and other users to choose the method most appropriate for measuring restoration success. 65 pages.

Natural Community Classification (Statewide)

 

Natural Communities of New Hampshire (Second Edition). Updated version of classification and detailed descriptions of terrestrial, freshwater wetland, and estuarine natural communities in New Hampshire. Includes an overview of major physical features and natural divisions (ecoregions) in New Hampshire. This book consolidates and supercedes all previous NH Natural Heritage classifications of natural communities in the state. 270 pages.
