Investigation Of Potential Distribution Of Aeschynomene Virginica In The Tidal Wetlands Of Ware Creek, Virginia : Final Report, James E. Perry Jan 1993

Investigation Of Potential Distribution Of Aeschynomene Virginica In The Tidal Wetlands Of Ware Creek, Virginia : Final Report, James E. Perry

Reports

The distribution and population densities of a federal listed threatened plant species, the northern joint vetch (Aeschynomene virginica), was determined in the vicinity of the proposed Ware Creek Reservoir site in James City County and New Kent County, Virginia. The proposed study was intended to determine the size, limits, and density of extant populations of the northern joint vetch in the project area, and to investigate the possible impacts the project may have on the extant populations. Where necessary, possible mitigation procedures are discussed.


Distribution Of Aeschynomene Virginica In The Scotland Landing Region Of The Mattaponi River, Virginia, James E. Perry Jan 1993

Distribution Of Aeschynomene Virginica In The Scotland Landing Region Of The Mattaponi River, Virginia, James E. Perry

Reports

The distribution and population densities of a federal listed threatened plant species, the northern joint vetch (Aeschynomene virginica), was determined and mapped in the vicinity of a proposed Mattaponi River water withdrawal structure. The proposed study was intended to determine the size, limits, and density of extant populations of the northern joint vetch in the project area, and to investigate the possible impacts the project may have on the extant populations. Where necessary, . possible mitigation procedures are discussed.


Identification Of Historic Locations Of Aeschynomene Virginica Within The Tidal Freshwater Zone Of The Pamunkey River, Virginia : Final Report, James E. Perry Jan 1993

Identification Of Historic Locations Of Aeschynomene Virginica Within The Tidal Freshwater Zone Of The Pamunkey River, Virginia : Final Report, James E. Perry

Reports

The historical distribution and population densities of a federal listed threatened plant species, the northern joint vetch (Aeschynomene virginica), was determined and mapped in the tidal regions of the Pamunkey River, Virginia, where a potential water withdrawal structure is being evaluated.


Effects Of Nutrient Enrichment On Natural And Transplanted Salt Marshes In Virginia : A Literature Review With Management Recommendations - Final Report, R. D. Rheinhardt, J. D. Perry Jan 1993

Effects Of Nutrient Enrichment On Natural And Transplanted Salt Marshes In Virginia : A Literature Review With Management Recommendations - Final Report, R. D. Rheinhardt, J. D. Perry

Reports

This study was initlated in response to a request by SEAS to review their technical recommendations concerning the fertilization of tidal salt marshes and determine whether those recommendations are sound in light of current scientific knowledge. The intention of this analysis was to determine whether benefits are derived from applying nutrients to marshes, and if so, whether those benefits outweigh the costs associated with the potential pollution of Chesapeake Bay's tidal waters.

To provide insight into the effects of adding fertilizers to salt marshes, the scientific literature was examined from four perspectives:

1) the dynamics of ·nutrient cycling in natural …
