Crommet Creek Conservation Area Management Plan, Joanne Glode, Dea Brickner-Wood, Ed Robinson, Wendy Weisiger, Peter Wellenberger, Rachel Stevens

PREP Reports & Publications

The Crommet Creek Conservation Area comprises the largest block of natural lands in the immediate Great Bay watershed, and in New Hampshire’s North Atlantic Coast Ecoregion. It includes the entire watershed of two tidal creeks that flow directly into the Great Bay Estuary. The area has been identified by the Great Bay Resource Protection Partnership as a protection priority due to the size of the natural area; the diversity of habitats and wildlife it supports; and it’s integral role in protecting the regional water quality and resources within the Great Bay Estuary. The Conservation Area includes headwater wetlands, and the …

Tracking Environmental Trends In The Great Bay Estuarine System: An Examination Of Water Quality And Nuisance Macroalgal Blooms, Jeremy C. Nettleton

Doctoral Dissertations

Monitoring macroalgae populations is an effective means of detecting long term water quality changes in estuarine systems. To investigate the environmental status of New Hampshire's Great Bay National Estuarine Research Reserve, this study assessed the abundance/distribution of macrophytes, particularly Gracilaria and Ulva species, relative to eutrophication patterns; compared historical (1970s-1990s) and current algal biomass/cover at several sites; and compared Ulva and Gracilaria tissue N/P content to ambient and historical levels. Nitrogen and phosphorus testing revealed that the estuarine system has become eutrophic, and Ulva and Gracilaria biomass/cover have increased significantly. The percent cover of Ulva species, at seasonal maxima, was …

Ecosystem Structure And Function In An Urban, Piped Stream, Amanda Hope

Master's Theses and Capstones

Piped streams, or streams that run underground, are common features in urban areas. However, there is little empirical evidence regarding their ecological structure and function. This study measured ecosystem metabolism, nutrient uptake, and related characteristics of Pettee Brook -- an urban stream that flows through several pipes under impervious surfaces near the UNH (Durham) campus.

Piped and open reaches of Pettee Brook had similar water quality, nutrient uptake, and ER. However, the absence of light in piped reaches led to their complete loss of GPP. Benthic AFDM and chlorophyll a biomass were also significantly reduced in piped reaches. For both …
