Jurisdictional Environmental Coordination, Gloucester County, Virginia, Pamela Mason, Carl Hershner Jan 2003

Jurisdictional Environmental Coordination, Gloucester County, Virginia, Pamela Mason, Carl Hershner

Reports

The ability to coordinate the management of human activities in the landscape from an environmental perspective has been a desired, yet elusive, interest. The ability to accurately value environmental functions economically has confounded this process; but conflicts are not confined to the obvious ones between economics and the environment. Even those activities within the field of environmental management are not always harmonious. A myriad of management activities administered at various levels of government results in a web of responsibilities lacking in any central coordination. Varied local, state, and federal programs administered by different agencies have missions that put them in …

An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr. Nov 2002

An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr.

Reports

This project was done in response to concerns by environmental resource managers of historic and potential adverse impacts to Virginia’s secondary dune ecosystems. Virginia environmental regulatory programs have little decision-making authority over the use of secondary dunes as these areas are not included in the Coastal Primary Sand Dune Act (the Dunes Act). These areas function as estuarine edge habitat and provide natural upland erosion control, and are thus valuable to estuarine and coastal plain fauna and adjacent upland property owners.

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2001 Annual Report, John E. Olney, Kristin L. Maki Apr 2002

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2001 Annual Report, John E. Olney, Kristin L. Maki

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, spawning …

Virginia’S Coastal Program: Strategic Mapping Of Management Goals, Jennifer Newton, Pamela Mason, Carl Hershner

Reports

Virginia’s Coastal Resources Management Program is a networked program bringing together the activities of many state agencies and institutions to achieve the overarching mission of coastal zone management. The Program’s objectives were originally set out in a series of 25 goals in the 1986 Executive Order (see Appendix B) that established the Program for the Commonwealth under the federal Coastal Zone Management Act. Beginning in May of 1999, representatives of the Virginia state agencies involved with the networked Coastal Program attended a series of meetings to develop logic maps of these twenty-five goals. This document represents the final results of …

Estimating Relative Abundance Of Young Of The Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Patrick J. Greer

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan for American Eel (FMP) in November 1999. The Plan focuses on increasing the states’ efforts to collect data on the resource and the fishery it supports through fishery dependent and independent studies. To this end, member jurisdictions (including Virginia) agreed to implement an annual abundance survey of young-of-year American eel (YOY). The survey is intended to “...characterize trends in annual recruitment of the young of the year eel over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic coast …

Reports

The data inventory developed for the Shoreline Situation Reports are based on a three-tiered shoreline assessment approach. This assessment characterizes conditions in the shorezone observed from a small boat moving along the shoreline. Handheld GPS units record data observations in the field. The three tiered shoreline assessment approach divides the shorezone into three regions:

  1. the immediate riparian zone, evaluated for land use

  2. the bank, evaluated for height, stability, cover and natural protection

  3. the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2000 Annual Report, John E. Olney, John M. Hoenig Apr 2001

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2000 Annual Report, John E. Olney, John M. Hoenig

Reports

Since the moratorium, there have been no monitoring programs that provided direct assessment of stock recovery until this project began in 1998. The ban on in-river fishing in Virginia remained in effect, creating a dilemma for managers who needed reliable information in order to make a rational decision on when the in-river ban could safely be lifted. To address this deficiency, we proposed a method of scientific monitoring to estimate catch rates relative to those recorded before the prohibition of in-river fishing in 1994. This monitoring program began in 1998 and consisted of sampling techniques and locations that were consistent …
