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.

Great Barrier Reef Report Card Summary - 2009 Baseline (Page 1)

Great Barrier Reef Report Card Summary - 2009 Baseline

Bill Dennison, Heath Kelsey, Jane Thomas, Melissa Andreychek ·
12 August 2011

The Great Barrier Reef is the largest and best-known coral reef ecosystem in the world. This first report card provides an estimate of the status of the key indicators for the period preceding 2009. It is based on historical data and trends and takes into account the influence of a variable climate from year to year. This serves as a baseline that will be used as a point of comparison to measure progress towards Reef Plan goals and targets.

12 August 2011

This document contains report card summaries for the Cape York, Wet Tropics, Burdekin, Mackay-Whitsunday, Fitzroy, and Burnett-Mary regions. Each section details the region profile, and key findings, as well as summarizing the report card results for land practices, catchment indicators and loads, and the marine parameters; water quality, seagrass, and corals. It also describes positive actions in the regions to improve ecosystem health.

12 August 2011

The Great Barrier Reef World Heritage Area is renowned internationally for its ecological importance and beauty. However, despite it being one of the best managed coral reefs in the world there is a very real risk of damage to the reef from climate change. This technical document details all aspects of the report card process. It includes sections on management, methods, and detailed results for all regions.
