Greenhouse Gas Reduction Plan: Chapter 8 Adaptation

Caroline Donovan, Marcus Griswold ·
24 July 2013

Climate change will affect Maryland in a variety of ways. More obvious impacts could include an increased risk for extreme events such as drought, storms, flooding, and forest fires; more heat-related stress; the spread of existing or new vector-born disease; and increased erosion and inundation of low-lying areas along the State’s shoreline and coast. Adaptation, together with mitigation, is necessary to address climate change.

Resiliency and water resources management: Water supply in a changing climate

Maryland citizens are blessed with an abundant supply of water. However, many water systems are already stressed during droughts, and infrastructure damage and water contamination occurs during floods. Future population growth will combine with increasingly variable weather patterns to place more communities at risk of property damage, regulatory liabilities and uncertain access to drinking water.

Best Management Practices: Preserving clean water in a changing climate

Risk management is critical in any restoration project. Risks include those associated with climate patterns, such as more intense storms, as well as those associated with land use change, site selection, and design. Addressing these risks in conjunction with ongoing restoration efforts will prepare communities for greater variability and may result in cost savings and reduced risk. Best Management Practices (BMPs) should be sited and designed with climate change impacts in mind.

Maryland’s extensive aquatic ecosystems range from freshwater swamps and bogs to freshwater rivers and marshes to coastal bays and salt marshes. These ecosystems are influenced by precipitation, temperature, tropical storms, and human activity. Human development and pollution have degraded their natural resilience, leaving them more vulnerable to climate change and extreme events.

2012 Chesapeake Bay Report Card (Page 1)

2012 Chesapeake Bay Report Card

Caroline Donovan, Bill Dennison, Heath Kelsey, Alexandra Fries ·
3 July 2013

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay. In 2012, the methods for the report card have changed to include five water quality indicators and two biotic indicators. In 2012, the overall grade for Chesapeake Bay is a 47%, a C. This means the Bay is in moderate health. Fisheries indicators as well as trajectories of reporting region health are also presented. For further details, visit the Report Card website .

Sampling and data analysis protocols for Mid-Atlantic non-tidal stream indicators (Page 1)

Sampling and data analysis protocols for Mid-Atlantic non-tidal stream indicators

Wicks EC, Fries AS and Kelsey RH ·
7 May 2013

This document provides guidelines for the successful production of non-tidal stream health report cards. Specifically, this document develops clear and consistent protocols for the identification, collection, and analysis of indicators to be used by report card-producing organizations in Mid-Atlantic rivers and streams.

Oyster deltaN-15 as a Bioindicator of Potential Wastewater and Poultry Farming Impacts and Degraded Water Quality in a Subestuary of Chesapeake Bay (Page 1)

Oyster deltaN-15 as a Bioindicator of Potential Wastewater and Poultry Farming Impacts and Degraded Water Quality in a Subestuary of Chesapeake Bay

Fertig BM, Carruthers TJB, and Dennison WC ·
2013

Anthropogenic nitrogen contributes to water quality degradation, but it is difficult to distinguish sources once they are mixed in coastal ecosystems. Natural abundances of stable nitrogen isotopes (deltaN-15) were measured in oyster (Crassostrea virginica) tissues (muscle, gills, and mantle) during summer 2006 to summer 2008 to identify nitrogen sources in Monie Bay (a subestuary of Chesapeake Bay) receiving freshwater inputs from three tributary creeks. The creeks (estimated flushing times:

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.

Focus Group Evaluation of Tributary Report Cards

26 April 2012

The Chesapeake Bay Trust, West/Rhode Riverkeeper, and OpinionWorks have conducted an audience evaluation of tributary report cards, conducted through focus groups. This report provides the findings and recommendations that arise from this research. The report also serves as a best management guide for creating report cards that not only report on water quality, but also engage the public in the work of protecting the Bay and its tributaries.
