DESIGNING WETLAND CONSERVATION STRATEGIES UNDER CLIMATE CHANGE
A methodology for evaluating public wetlands conservation investments that considers climate change is developed and applied to Virginia's Elizabeth River watershed. A revised cellular automaton (CA) model is applied to project future land use change. Discrete stochastic sequential programming (DSSP) is used to model a parcel-based discrete-time decision process.Environmental Economics and Policy,

Environmental Research Letters 4 (2009): 044008, doi:10.1088/1748-9326/4/4/044008.Rising sea level threatens existing coastal wetlands. Overall ecosystems could often survive by migrating
inland, if adjacent lands remained vacant. On the basis of 131 state and local land use plans, we estimate that
almost 60% of the land below 1 m along the US Atlantic coast is expected to be developed and thus unavailable
for the inland migration of wetlands. Less than 10% of the land below 1 m has been set aside for conservation.
Environmental regulators routinely grant permits for shore protection structures (which block wetland migration)
on the basis of a federal finding that these structures have no cumulative environmental impact. Our results
suggest that shore protection does have a cumulative impact. If sea level rise is taken into account, wetland
policies that previously seemed to comply with federal law probably violate the Clean Water Act

Six fish and 600,000 thirsty folks - A fishing moratorium on American shad thwarts a controversial municipal reservoir project in Virginia, USA
Moratoria on fishing directly impact fishers, distributors and marketers of product and can have serious socio-economic implications. Moratoria can impact communities but usually populations closely linked to the banned activity. In an unprecedented example, a moratorium on fishing in Virginia has directly impacted a nonfishing citizenry by thwarting plans for a public utility. In May 2003, a panel empowered to regulate marine resources denied permission to withdraw raw water from a pristine freshwater river, the Mattaponi. The controversial action spoiled a multi-million dollar plan to establish the King William Reservoir, a water source considered essential to future growth and development in the region. The facility was designed to serve a projected 600,000 people in 2040 but the Mattaponi Indians, environmentalists, local citizens and commercial fishers opposed the plan. A central issue was conservation of American shad Alosa sapidissima, an anadromous clupeid native to the U.S. east coast. An inriver moratorium on fishing for American shad imposed in 1994 remains in effect. In the reservoir debate, scientists advised the panel that the project would withdraw water in the center of the larval nursery area for this species and in a river that accounted for the highest statewide production of juveniles. Scientists recommended relocating the intake since losses of larvae to withdrawal could be counter to restoration goals of the moratorium. Using quantitative models, municipal authorities argued that only six American shad would be lost annually to impingement or entrainment. The panel rejected this argument and proposals to mitigate losses.https://scholarworks.wm.edu/vimsbooks/1012/thumbnail.jp
