Measuring effectiveness of Best Management Practices

Simon Costanzo, Bill Dennison, Alexandra Fries ·
22 October 2012

The Chesapeake and Atlantic Coastal Bays Trust Fund was created in 2007 in an effort to reduce nutrient and sediment pollution to these bays. The Trust Fund has focused its financial resources on the implementation of effective non-point source pollution control projects using best management practices (BMPs) in high priority watersheds. Examples of projects supported by the Trust Fund include stream channel restorations, stormwater retrofits, and cover crops.

A vision for America's Great Watershed Report Card

Heath Kelsey, Caroline Donovan, Brianne Walsh, Jonathan Kellogg, Bill Dennison, Alexandra Fries ·
27 September 2012

Report cards can be part of a tiered approach to communicating results with varying technical detail. Our vision for this report card framework is based on goals identified in America’s Great Watershed Initiative and derived from principles of Integrated River Basin Management. The framework includes balanced information from Social, Economic, and Environmental sectors, and is intended to be transparent and clear.

17 July 2012

The burden of global, regional, and project reporting has been a longstanding concern of Pacific Island Countries and Territories (PICTs), particularly on Smaller Island States (SIS). This newsletter uses an environmental case study to showcase how a simple, targeted, and strategic monitoring and reporting framework can facilitate streamlined reporting by allowing data and information to be used for multiple reporting requirements.

Colonial National Historical Park natural resource condition assessment (Page 1)

Colonial National Historical Park natural resource condition assessment

Lookingbill T, Bentsen CN, Carruthers TJB, Costanzo SD, Dennison WC, Doherty C, Lucier S, Madron J, Poppell E and Saxby TA ·
28 June 2012

Colonial National Historical Park offers a vast array of cultural resources, notably the site of the first English settlement at Jamestown in 1607 and the Siege of Yorktown in 1781 that proved to be the last major campaign of the American Revolution. Four dominant habitat groupings are present within the Park, including forest, grassland, non-tidal wetland, and tidal wetland. Threats to Colonial NHP have been categorized into:

2011 Chesapeake Bay Report Card (Page 1)

2011 Chesapeake Bay Report Card

Bill Dennison, Caroline Donovan, Jonathan Kellogg, Alexandra Fries ·
17 April 2012

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay. The overall health of Chesapeake Bay, determined using water quality and biotic indicators, declined slightly in 2011. The overall grade of D+ was a decrease for the second year in a row, down from a C- in 2010. Only two reporting regions, the Patapsco and Back Rivers, and the Lower Western Shore (MD), had improved grades in 2011.

A Habitat-Based Framework for Communicating Natural Resource Condition (Page 1)

A Habitat-Based Framework for Communicating Natural Resource Condition

Carruthers TJB, Carter SL, Lookingbill TR, Florkowski LN, Hawkey JM, and Dennison WC ·
2012

Progress in achieving desired environmental outcomes needs to be rigorously measured and reported for effective environmental management. Two major challenges in achieving this are, firstly, how to synthesize monitoring data in a meaningful way at appropriate temporal and spatial scales and, secondly, how to present results in a framework that allows for effective communication to resource managers and scientists as well as a broader general audience.

Megacities in the coastal zone: Using a driver-pressure-state-impact-response framework to address complex environmental problems (Page 1)

Megacities in the coastal zone: Using a driver-pressure-state-impact-response framework to address complex environmental problems

Sekovski I, Newton A, and Dennison WC ·
2012

The purpose of this study was to elaborate on the role of coastal megacities in environmental degradation and their contribution to global climate change. Although only less than 4 percent of the total world's population resides in coastal megacities, their impact on environment is significant due to their rapid development, high population densities and high consumption rate of their residents.

A vision for the Gulf of Mexico Report Card

McKinney L, Tunnell W, Harwell M, Gentile J, Dennison WC, Kelsey RH, Thomas JE ·
7 December 2011

The Harte Research Institute for Gulf of Mexico Studies of Texas A&M University-Corpus Christi, has partnered with IAN and Harwell Gentile & Associates, LC, to develop a vision for a report card on the health of the Gulf of Mexico. The report card will be a graphical representation of the environmental condition of the Gulf that is scientifically based, widely accessible, and readily understandable by policy-makers, stakeholders, scientists, and, most importantly, the general public.

Healthy Darwin Harbour: Pathways and Partnerships (Page 1)

Healthy Darwin Harbour: Pathways and Partnerships

Bill Dennison, Jane Thomas ·
9 November 2011

Darwin Harbour is globally significant as a tropical, macrotidal, monsoonal harbour that is generally in very good condition. There are major development proposals for Darwin Harbour, including significant plans for population growth, industrial expansion and resource processing infrastructure, and consequent increases in shipping and dredging. These developments pose risks for the natural, cultural, aesthetic and recreational values of the Harbour, which need to be managed.
