EXECUTIVE SUMMARY

The Patuxent Wildlife Research Center hosts an Annual Science Meeting of Center scientists and Federal, State, and local partners in natural resource management. This meeting is designed to encourage a maximum amount of dialogue among Center scientists and science partners for the purpose of identifying respective capabilities and information needs and capturing emerging issues. The meeting results are used to shape scientific programs at the Center that are highly relevant to natural resource management needs and maintain high standards of professional excellence. Several areas of emphasis are selected for in-depth discussions at each meeting. One area so highlighted at the February, 1999, meeting was the coastal zone. During two, half-day sessions, internationally recognized leaders in coastal ecology joined forces with Department of the Interior coastal land and resource managers to identify key scientific issues, information gaps, and long-term data needs that are relevant within a coastal resource management framework. Although the issues that arose are applicable at national and global scales, the primary focus of discussions was the eastern U.S. The issues that were identified are summarized here. We hope that this information will yield productive partnerships among scientists and managers whose interests, expertise, and jurisdiction coincide in Atlantic and Great Lakes coastal habitats.

The need for a coordinated approach to research and management of coastal ecosystems has never been greater. Continued population growth in the coastal zone and concomitant urban, industrial, and agricultural development threaten natural resources with a host of anthropogenic stressors. Scott Nixon (University of Rhode Island) identified the primary anthropogenic sources of inorganic nitrogen to coastal waters, including fossil fuel combustion, fertilizer application, sewage treatment plant discharge, and septic system runoff. With increasing world populations and demographic shifts to coastal population centers, fertilizing inputs of nitrogen to estuaries and coastal embayments are expected to rise. Unchecked, the ultimate response to nutrient over-enrichment will be increased eutrophication of coastal systems. Barnett Rattner (USGS) described how resident and migratory vertebrate wildlife of Atlantic coast estuaries are also at risk from environmental contaminants. David Burdick (University of New Hampshire) discussed the historic and continued physical alterations to coastal habitats. Direct impacts to salt marsh and seagrass habitats arise from sediment fill or removal associated with upland and nearshore development projects, and indirect effects persist from hydrologic alterations. As described by Jim Allen(USGS), natural processes contributing to shoreline change can exacerbate the effects of human alterations to coastal environments.

Effective preservation and restoration of coastal ecosystems requires a collaborative approach for establishing research and management priorities, conducting necessary investigations, and applying new information. Problems in the coastal zone stem from complex processes interacting across a variety of temporal and spatial scales, and they require integrated, interdisciplinary responses. Bruce Hayden (University of Virginia / National Science Foundation) described how place-based, long-term ecological research can help detect trends in processes and causes for responses that occur on generational time scales. Peter Barnes (USGS/GD) and Peter Weiskel (USGS/WRD) described broad ranging, physical science expertise within USGS for addressing shoreline change and land-to-sea fluxes of water and materials. These capabilities complement the traditional ecological expertise at Patuxent, and Suzette Kimball, USGS/BRD Eastern Regional Chief Biologist, pledged collaboration across USGS Divisions to tackle coastal issues. Linkages with partner bureaus are essential to this process. Representatives of the National Park Service and the Fish and Wildlife Service with responsibilities for coastal lands and resources in the eastern U.S. identified many common themes, concerns, and information needs related to coastal ecosystem management.

This report is organized within overarching categories presented at the Coastal Issues Symposium: Physical Alterations of Coastal Habitats; Nutrient Enrichment: Sources and Ecosystem Responses; Shoreline Change Processes; and Long-term Monitoring and Research. Each issue includes recommendations for future scientific programs, based on information needs presented by partner bureau representatives and discussions among symposium participants. Specific science needs identified by National Park Service and Fish and Wildlife Service representatives are appended with contact information. We hope that this report serves as a springboard for future professional interaction, collaboration, and scientific investigation of coastal ecosystems in the eastern U.S.

NUTRIENT ENRICHMENT OF COASTAL SYSTEMS

Issues

Increasing world population and continued settlement of the coastal zone is causing nutrient enrichment of coastal ecosystems worldwide. Residential, agricultural, and urban development associated with burgeoning coastal populations has resulted in increased nutrient levels of both surface and ground water supplies. Anthropogenic sources of nutrient loading include septic systems, sewage treatment plants, and fertilizer application. Atmospheric deposition of nitrogen from fuel emissions also contributes to nutrient enrichment of coastal waters, as does mineralization of organic matter inputs from agriculture and aquaculture operations, sewage waste water, and industrial effluents. Excessive nutrient enrichment causes changes in the structure and function of coastal ecosystems. Common ecosystem responses include increased algal growth, increased community metabolism, and decreased dissolved oxygen concentrations. Ultimate changes in ecosystem structure include shifts in the dominant primary producers and alterations of communities of benthos, shell- and finfish, and higher consumers.

Research Needs Relevant to Resource Management

1. Quantify nutrient loading to coastal waters from surface water, ground water, and atmospheric sources.

2. Develop models to predict nutrient loading from easily measurable parameters within developed and undeveloped watersheds.

3. Determine responses of coastal ecosystems to nutrient loading and identify thresholds for specific habitat responses.

4. Quantify responses of higher trophic levels to coastal nutrient enrichment.

5. Determine adequate buffer distances adjacent to upland development projects to protect wetland and estuarine habitats from excessive nutrient inputs.

6. Quantify the cumulative effects of localized point- and non-point source nutrient inputs on coastal watersheds.

PHYSICAL ALTERATIONS OF COASTAL HABITATS

Issues

Historically, human activities have altered coastal vegetated environments through both direct and indirect mechanisms. Direct physical alterations to salt marsh and seagrass habitats include sediment fill associated with upland development, storm protection, or dredge spoil disposal; sediment removal associated with ditching or dredging projects; and physical disturbance from vessels and aquaculture operations. Indirect alterations result from disruptions to physical processes that contribute to maintaining ecosystem structure and function. Examples of such indirect habitat alterations include restriction of tidal flow with dams, causeways, undersized culverts, and other obstructions; changes in freshwater inputs due to dams, sewer and storm drain outfalls, and other types of upland development; and stabilization of shorelines with groins, jetties, and seawalls. Direct and indirect alterations operate at multiple scales, from the level of individual plants to watersheds. In many cases the long-term and cumulative impacts on the structure, function, and sustainability of coastal habitats are unknown. This type of information is needed to guide restoration efforts and predict the outcomes of specific restoration actions. Ultimately, best management practices must be defined to minimize negative effects of surrounding land use on coastal wetland and estuarine habitats.

Research Needs Relevant to Resource Management

7. Determine the long-term impacts of anthropogenic physical disturbance on the structure, function, and sustainability of coastal habitats

8. Evaluate the cumulative effects of small, incremental alterations on coastal habitats

9. Quantify ecosystem responses to various habitat restoration and enhancement practices

10. Identify ecological indicators, standards, and criteria for evaluating the success of restoration efforts

11. Identify immediate threats to living resources from recreational and commercial activities in the coastal zone (e.g. personal watercraft, tour boats, commercial fishing practices)

12. Quantify the causal relationships between physical habitat alterations and detrimental effects of invasive species

13. Identify critical habitat conditions to protect, restore, and manage rare species that are threatened by physical alterations to coastal ecosystems

LONG-TERM MONITORING AND RESEARCH
ISSUES

Biological and physical structures and processes in the coastal zone are driven to a great extent by long-term and large-scale climate- and ocean- related phenomena. Seasonal and annual variability in storms, ocean temperature, erosion/deposition patterns, shoreline development, and plant and animal community development and succession, are examples of coastal processes that require long-term records to understand. Layered over regional processes are local, human developments, such as revetments, channel dredging, introduction of species, and the like; coastal ecosystems respond to such human interventions over the course of years. Understanding long-term phenomena requires a knowledge of ecosystem variation at many scales - seasonal, annual, interannual, decadal and longer - in order to conserve and manage coastal resources at the appropriate scale. Too often, we mistake interannual variation for effects of human impacts or, at minimum, cannot separate human impacts from natural variation. Long-term data can assist us in separating local from regional and anthropogenic from natural effects.

Coastal ecosystem managers in the Department of Interior and other agencies need to be able to address their management needs at the appropriate scale and distinguish long-term trends from short-term natural variation. Managers need to target efforts on trends that can be managed and improved and to recognize ecosystem responses to long-term effects, such as sea-level rise, that cannot be controlled but may be accommodated. Long-term studies and long-term monitoring can provide managers with the necessary information on variation, scale and trends.

1. Air pollution

Issue:  Acadia National Park is a Class 1 airshed under the Clean Air Act. Because of Acadia=s unique location in relation to patterns of continental air flow the Park is a recipient of much air pollution. Determining the biological ramifications of airborne pollutants, including ozone, sulfur dioxide, nitrogen oxides, volatile organic compounds, mercury, and acid precipitation on Park ecosystems is a high priority.

Information needs:

How do Park coastal wetlands respond to
increasing amounts of septic waste and
yard fertilizers associated with new and
expanding residential development on
Mount Desert Island?

What are the ecological consequences for
Park plant and animal populations of
increasing habitat fragmentation outside
the Park boundary?

3. Conservation of biological diversity - plants

Issue: Acadia supports a very diverse flora due to its location at the intersection of two biogeographic regions and its topography. Many plant species in the Park are considered locally rare and several are listed as globally rare. Although inventories of Park flora have been completed, basic information on factors controlling the distribution and abundance of rare species and communities is lacking. Invasive plant species pose a significant threat to native plant communities in the Park.

Information needs:

Some of the rarest Park plants are
abundant in other parts of Maine or
New England. Should the NPS be
concerned about their rarity in Acadia
National Park? What is the Park=s role
in protecting rare plants?

Should we be trying to protect certain
plant populations when their rarity may
be related to a natural extinction or
the result of vegetation succession?

What are the statistically appropriate
long-term monitoring techniques for
small populations of rare plants?

What are cost-effective techniques to
control highly invasive non-native plants
at the Park, such as Japanese
barberry, alder buckthorn, and oriental
bittersweet?

How do sub-alpine plant communities and
boreal forests at Acadia respond to
anticipated changes in climate?

What are the long-term effects of
browsing on plant succession in a
post-fire forest environment?

4. Conservation of biological diversity - animals

Issue: Good baseline inventory data exist on some groups of animals, including large mammals, birds, and invertebrates. The historic invertebrate records are particularly extensive, from nearly 30-years of invertebrate surveys in the first part of this century. Baseline data on other animal groups is lacking (estuarine and anadromous fish) or incomplete (amphibians and reptiles). Information on the ecology of various species is also needed.

Information needs:

Have there been changes in the
invertebrate fauna over the last 75
years?

1. Wildlife use of seasonally saturated wetlands on the coastal plain

Issue:  From New Jersey south on the Atlantic Coast, the coastal plain is characterized by wet flatwoods dominated by loblolly pine and other species, including various hardwoods. Many of these wetlands are isolated and are not currently regulated under Federal law. USFWS has trust responsibilities for wetlands in general, and for recovery of the Delmarva fox squirrel, an endangered species that uses this particular type of wetlands.

Information needs:

What species are at risk due to unregulated development
of these wetlands?

To what extend do wildlife rely on these drier-end wetlands?

2. Buffers for wildlife protection

Issue: Many wetland and riverine restoration projects are undertaken annually by the USFWS, NRCS, EPA, and US Army Corps of Engineers, both to improve the integrity of coastal watersheds and to mitigate for permitted wetland conversions. However, protocols do not exist for the types and widths of upland buffers that should be included in stream reforestation or wetland restoration projects.

Information needs:

What are adequate sizes of buffers
along wetlands and streams to support
wildlife?

How dependent are wetland wildlife on
wetland buffers and stream corridor
buffers?

3. Appropriate level of monitoring for wetland restoration or creation projects

Issue:  Despite the investment of Federal funding in wetland restoration and, to a lesser amount, creation, the preponderance of effort is expended on determining areas suitable for restoration, securing any necessary permits, and the actual restoration activity. Very little attention has been given to monitoring in either the restoration or regulatory (i.e. restoration as compensatory mitigation) arenas. It is critical that an appropriate level of monitoring be instituted to ensure that projects are meeting their scientific objectives.

Information needs:

What hydrologic indicators should be
monitored to determine whether a
restored wetland is recreating the lost
functions and values of the original system?

What vegetation indicators should be
monitored to determine whether a
restored wetland is recreating the lost
functions and values of the original
system?

What is the appropriate longevity of a
monitoring program?

4. Cumulative impacts of coastal development

Issue:  Degradation of estuarine and nearshore habitats is a product of numerous small-scale development projects that incrementally affect water quality and aquatic resources. The cumulative impacts of such small-scale alterations are poorly understood.

Information needs:

What are the cumulative effects of
small-scale development such as septic
systems, docks and pier construction,
and localized non-point source pollution
on coastal watersheds and estuarine
systems?

5. Essential components of watersheds

Issue: Coastal watersheds in the Northeast are generally degraded to varying extents. Indicators of general ecosystem health should be developed to help decision makers prioritize restoration projects.

Information needs:

What are the characteristics of an
ecologically healthy watershed?

What characteristics must be maintained
to sustain ecological health?

To what extent can a watershed be
degraded and still maintain ecological
functions (i.e., can Aassimilative
capacity@ be measured)?

6. Habitat requirements for living resources

Issue:  The Chesapeake Bay Federal Interagency Program published AHabitat Requirements for Chesapeake Bay Living Resources@ in 1991. Since this time, similar characterizations have been done for other estuaries.

Information needs:

Augment existing literature on species
determined to be characteristic or
indicator species of an estuary.

7. Species at risk

Issue:  Proactive strategies are needed to reverse species= declines and preclude the need for listing under the Endangered Species Act.

Information needs:
