Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick
Reports
Shoreline habitats and processes are impacted by the decisions we make about managing coastal development and shorelines. Shoreline Management is making choices to address the desire to protect upland property from erosion or develop property balanced with the benefits and uses of natural and nature-based shoreline features and shoreline habitat restoration. This requires a weighing of the private benefits and cots of management actions and the benefits and costs to public held common resources, also known as the public trust. The natural features along our shorelines -tidal wetlands, beaches and dunes, and riparian buffers, are economically and ecologically valuable. They …

Assessing Ecological And Economic Effects Of Derelict Fishing Gear: A Guiding Framework, Christopher F.G. Jeffrey, Kirk J. Havens, H. Ward Slacum Jr., Donna Marie Bilkovic, Danielle Zaveta, Andrew M. Scheld, Sean Willard, John D. Evans
Reports
Developing standardized protocols to assess the ecological and socio-economic effects of marine debris – especially, derelict fishing gear – is critical for the protection of natural resources and for evaluating policies and programs designed to reduce and remove debris. This document outlines a Derelict Fishing Gear Assessment Framework to guide the development and implementation of derelict gear assessment, management and mitigation. The framework draws from techniques and protocols developed to assess derelict crab traps effects in the Chesapeake Bay and on past derelict gear assessments either conducted by or known to the framework authors. However, this framework is generalized and …

Ecological And Economic Effects Of Derelict Fishing Gear In The Chesapeake Bay 2015/2016 Final Assessment Report, Donna M. Bilkovic, H. Ward Slacum Jr., Kirk J. Havens, Danielle Zaveta, Christopher F.G. Jeffrey, Andrew M. Scheld, David Stanhope, Kory Angstadt, John D. Evans
Reports
Derelict fishing gear represents a major challenge to marine resource management: whether through deliberate abandonment or through accidental loss, derelict traps in particular have significant negative effects both economic (e.g., reduced fishery harvest from ghost fishing and gear competition that leads to the reduced efficiency of active gear) and ecological (e.g., degraded habitats and marine food webs and crab and bycatch mortality). Throughout the Chesapeake Bay, commercial harvest of hard-shelled blue crabs is a major fishing activity: every year sees the deployment of several hundred thousand blue crab traps (known locally as crab “pots”) across the Bay, of which an …

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell
Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell
Reports
Proliferation of artificial structures to protect shorelines has introduced novel habitat to most coastal environments and fragmented natural habitats. These changes can result in disrupted connectivity, habitat homogenization, and altered estuarine landscapes, with uncertain implications for estuarine and marine faunal community structure and function. In estuaries, such as Chesapeake Bay, where soft-bottom habitat dominates and rocky shorelines are rare, the introduction of artificial rocky structure may enhance recruitment of species that are limited by the availability of suitable substrate including native and introduced species (Bilkovic & Mitchell 2013). There is a significant lack of empirical data on the types of …

Reports
Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970's to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each of the Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. This is the first Shoreline Inventory Report for the Rehoboth Bay section of Delaware. Data collected describes conditions in the immediate riparian zone, the bank, and along the shore. There are three shapefiles that are part …

Reports
This shoreline inventory is developed as a tool for assessing conditions along primary shoreline in three watersheds that discharge into Delaware Bay. Field data were collected between September 11-13, 2007. Conditions are reported for three zones within the immediate riparian river area: riparian land use, bank and buffers, and the shoreline. A series of maps, tabular data, and GIS files are posted to a website and available electronically to serve as a resource to all managers and planners within the three watersheds. The survey provides a baseline to which future conditions can be compared and tracked through time.
