Targeted Ecological Areas

Targeted Ecological Areas (TEAs) are lands and watersheds of high ecological value that have been identified as conservation priorities by the Maryland Department of Natural Resources (DNR) for natural resource protection. These areas represent the most ecologically valuable areas in the State: they are the "best of the best". TEAs are preferred for conservation funding through Stateside Program Open Space. This version updates the 2008 TEA layer. The first step in updating TEAs was to create an ecological baseline composed of several ecological databases which included updates of original databases and additional databases developed since 2008. The first component is the updated Green Infrastructure Assessment (circa 2010) which identifies large, contiguous blocks (hubs) of significant forests and wetlands and their connecting corridors. The Green Infrastructure’s hub and corridor network of habitat allows plant and animal migration, reduces forest fragmentation if protected, and provides important ecosystem services, such as biodiversity, cleaning air and water, storing nutrients, and protecting areas against storm and flood damage. The rare species and wildlife habitat component identifies areas that support Rare, Threatened, and Endangered Species, rare plant and animal communities, species of Greatest Conservation Need, and wildlife concentrations. The aquatic life hotspots component identifies watersheds supporting freshwater stream ecosystems where conservation is needed to protect and restore areas of high aquatic biodiversity, Tier II regulated streams, and brook trout streams. The water quality protection component identifies sensitive lands such as forests, wetlands, and steep slopes where preservation is important for water quality. The coastal ecosystems component identifies Blue Infrastructure shoreline and watershed protection priorities. These are areas important for sustaining coastal and tidal ecosystems and also identifies land areas important for sustaining spawning and nursery areas for important commercial and recreational fisheries. The climate change adaptation component identifies areas important for sustaining wetlands ecosystems that are changing and moving landward in response to sea level rise. From the ecological baseline, areas that ranked as most important for each of the components were merged to create the Targeted Ecological Areas. Lands that were developed, as identified by the Maryland Department of Planning (2010) were removed from the TEA layer since developed lands are not preferred for Stateside Program Open Space funding. Additionally, lands that are in the 0 foot to 2 foot inundation zone based on the 2011 SLAMM (Maryland Sea-Level Affecting Marshes Model) study performed for all 16 coastal counties and Baltimore City since these areas are not preferred for Stateside Program Open Space funding.

Maryland_Helicopter_Operations

Joint Base Andrews conducts low-level helicopter training operations across areas in southern Maryland and northern Maryland including along the Potomac River.There are three separate low-level flight areas associated with training at NAS Patuxent River, two of which are in Maryland – East Helicopter Operating Area and West Helicopter Operating Area. Both low-level flight areas cover a broad area of land across Calvert County, Dorchester County, St. Mary’s County, and Wicomico County in which NAS Patuxent River conducts low-level flight training operations with rotary-wing and some fixedwing aircraft.Some military flight training is conducted at altitudes below 10,000 feet above mean sea level, and sometimes even below 200 feet AGL. For example, nap-of-the-earth training exercises include aircraft flying just above ground level or tree line using terrain-following sensors to avoid radar detection. Due to the low altitudes and speeds of the aircraft, these training missions are conducted within designed low-level flight areas to avoid collisions with civilian aircraft. However, the development of tall structures can interfere with and create hazards for aircraft conducting low-level flight training.

Working Waterfront Points

In 2012 The Chesapeake and Coastal Service (CSS), a division of the Maryland Department of Natural Resources developed a pilot project to identify working waterfronts for both water dependent business and commercial watermen. The intent of the project was to compile an inventory of waterfront dependent Industries throughout the watershed of the Choptank River, which is located on the eastern shore of Maryland. The second year of the regional project expanded the year 1 pilot inventory focusing next on the lower eastern shore of Maryland including the Atlantic Coastal Bays, south of the Choptank watershed pilot study area to the Virginia border. On the western shore the inventory includes the Potomac River from Washington harbor to Point Lookout and then along the shore to the South River.

Yellow Perch Spawning Habitat

These datasets exist in raster and vector formats. The vector format was created from the SHA Shoreline file and graphic representations in the Lippson book (See bibliography below). These areas were then overlane with a point file created from lat/long collected during the surveys conducted by O'dell, Mowrer, and Uphoff of MD DNR Fisheries Service. This was done to verify that the graphic representations were accurate. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest. These ranked rasters were then stacked and an output raster was created showing areas of high habitat diversity. These rasters were then clipped by county.

Recreational Dive Fishing

As a member of the Mid-Atlantic Regional Council on the Ocean (MARCO), Maryland, through its Coastal Zone Management (CZM) Program is collecting information on how the public uses the Atlantic coast of Maryland. These baseline data will inform planning efforts being undertaken by the Maryland Department of Natural Recources to help develop a Maryland Ocean Plan. Collecting data on the variety of ways you use the Seaside Bays and Atlantic Ocean will help us plan for reducing use conflicts in our coastal waters, maximizing efficiency, and enhancing environmental and economic productivity. State and federally managed waters of Maryland and the U.S. are used in many ways: commercial fishing, aquaculture, shipping, military exercises, sand mining, habitat for wildlife, and recreation. With new and expanding coastal and ocean uses emerging such as energy production and increased shipping and considering Maryland coastal population is increasing, the pressure is mounting to ensure that there is space for both traditional and new uses and that conflicts are minimized. Some mapped human use data exist, but Maryland has limited recreational water use data for its Atlantic Coast and Coastal Bays. So basic data on how we use our coastal waters will be collected by inviting residents and experts to share their knowledge about recreational uses at workshops using geographical information systems technology.

Chesapeake Bay Horseshoe Crab Habitat

These data sets exist in raster and vector formats. The areas in this data set were derived from sitings called in and tracked by Steve Doctor at Matapeake. These sitings were located as points on a map that were contributed by Mr. Doctor and Nancy Butowski, DNR Fisheries Service. Professional guidance was provided by Nancy Butowski and Steve Doctor. The areas were then located on the VIMS shoreline data set and exported as an independent data set. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest. These ranked rasters were then stacked and an output raster was created showing areas of high habitat diversity. These rasters were then clipped by county.

Rivers and Streams - Generalized

The digital segmented network based on watershed boundaries, ERF1-2, includes enhancements to the U.S. Environmental Protection Agency's River Reach File 1 (RF1) (USEPA, 1996; DeWald and others, 1985) to support national and regional-scale surface water-quality modeling. Alexander and others (1999) developed ERF1, which assessed the hydrologic integrity of the digital reach traces and calculated the mean water time-of-travel in river reaches and reservoirs. ERF1-2 serves as the foundation for SPARROW (Spatially Referenced Regressions (of nutrient transport) On Watershed) modeling. Within the context of a Geographic Information System, SPARROW estimates the proportion of watersheds in the conterminous U.S. with outflow concentrations of several nutrients, including total nitrogen and total phosphorus, (Smith, R.A., Schwarz, G.E., and Alexander, R.B., 1997). This version of the network expands on ERF1 (version 1.2; Alexander et al. 1999), and includes the incremental and total drainage area derived from 1-kilometer (km) elevation data for North America. Previous estimates of the water time-of-travel were recomputed for reaches with water- quality monitoring sites that included two reaches. The mean flow and velocity estimates for these split reaches are based on previous estimation methods (Alexander et al., 1999) and are unchanged in ERF1-2. Drainage area calculations provide data used to estimate the contribution of a given nutrient to the outflow. Data estimates depend on the accuracy of node connectivity. Reaches split at water- quality or pesticide-monitoring sites indicate the source point for estimating the contribution and transport of nutrients and their loads throughout the watersheds. The ERF1-2 coverage extends the earlier ERF1 coverage by providing digital-elevation-model (DEM-based estimates of reach drainage area founded on the 1-kilometer data for North America (Verdin, 1996; Verdin and Jenson, 1996). A 1-kilometer raster grid of ERF1-2 projected to Lambert Azimuthal Equal Area, NAD 27 Datum (Snyder, 1987), was merged with the HYDRO1K flow direction data set (Verdin and Jenson, 1996) to generate a DEM-based watershed grid, ERF1_2WS. The watershed boundaries are maintained in a raster (grid cell) format as well as a vector (polygon) format for subsequent model analysis. Both the coverage, ERF1-2, and the grid, ERF1-2WS are available at: http://water.usgs.gov/lookup/gisgetlist. The version of RF1 used to compile ERF1-2 was an early edition of a USGS RF1 translation and was updated by USEPA (USEPA, 1996). The capabilities of the enhanced version of RF1 (ERF1-2) and the current USEPA version have not been evaluated. The user is referred to the USEPA version.

Sand Volume Estimates

Volumetric estimations for Fenwick, Weaver, & Isle of Wight shoals used vibracore data collected in 1992 & 1997, volumes were calculated in 2000 (Conkwright, Williams and Christiansen, 2000). Borrow Area 2 has been virtually exhausted by dredging. Between 1988-1992, ~2.9 million m^3 was dredged from Borrow Area 2, ~4.2 million m^3 dredged from Borrow Area 3, and ~3.2 million m^3 dredged from Borrow Area 9 (Wells, 1994). Revised volumentric estimations for Shoals B, C, D, Little Gull Bank & Great Gull Bank (1996) "In the 1993 sand resources study (Conkwright and Gast, 1994b) the seismically defined ravinement surface was used as the lower structural boundary for volume calculations. However, the purpose of the current study is to estimate only the volume of sand with measured physical parameters. Therefore, the lower boundary for volumetric calculations was determined primarily by the grain size parameters of vibracore samples. The lower boundary surface was set at the depth where the sampled sand became too fine or too poorly sorted for use as beach fill. In those cases where the entire length of core contained usable sand, the boundary surface was set at the depth of maximum vibracore penetration. Because vibracore penetrations on Little and Great Gull Banks were generally within a meter of the ravinement surface, that surface was used as the lower boundary for those shoals, unless vibracore samples indicated otherwise."

Maryland Wind Energy Area

Secretary Salazar announced the Department of the Interior's "Smart from the Start" initiative on November 23, 2010. As part of this initiative, a critical element is the identification of Wind Energy Areas (WEA) on the Outer Continental Shelf (OCS) off the Atlantic coast. WEAs are offshore locations that appear most suitable for wind energy development. Secretary Salazar identified the WEAs on February 7, 2011 in a joint announcement with Secretary Chu of the U.S. Department of Energy as part of the National Strategic Work Plan for Offshore Wind. Data has been and will continue to be collected for these high priority areas to inform government and industry assessments and planning, allowing a more efficient process for permitting and siting responsible development. Requests for Interest (RFIs) and Calls for Information have been or will be issued for these new WEAs to support lease sale environmental assessments. The data was developed within the U.S. Government; no proprietary rights may be attached to them nor may they be sold to the U.S. Government as part of any procurement of ADP products or services.

Maryland_Naval_Research_Lab_Radar_Areas

The Naval Research Laboratory areas of radar concerns. Radars locate an object’s position by emitting electromagnetic waves that reflect off objects, such as planes, birds, and mountains, and are returned to the radar. The electromagnetic waves that are returned to the radar provide the information needed to calculate an estimated size, location, speed, and direction of an object. The radar viewshed, or field of view, is the area that is within range of a radar’s electromagnetic waves. The range of the viewshed is influenced by multiple factors, including the radar’s look angle, terrain, weather, as well as natural and manmade objects. Natural and man-made structures within a radar’s field of view can limit the range of the viewshed by blocking electromagnetic waves, which impacts the integrity and usefulness of a radar in identifying and locating aircraft, watercraft, weather, or other objects such as missiles. Additionally, other electromagnetic activity, such as radio waves or microwaves, in the vicinity of a radar transmitter and/or receiver (typically within 8 to 10 miles) can interfere with the electromagnetic waves emitted by the radar. One of the most crucial components within the radar viewshed is the line-of-sight, which is the linear path between the transmitter and receiver (when not the same antenna). An obstruction to this linear path can result in loss communication signals between the transmitter and receiver rendering the radar ineffective.

Blue Infrastructure Watersheds

A subset of watersheds created for the Blue Infrastructure Project (BI) based on the DNR 12 digit watershes as follows; This file (SWSHED12) is a statewide digital watershed file. It was created primarily for state and federal agency use. The watersheds define Strahler (Strahler 1952 p. 1120) third order stream drainage by contours on U.S. Geological Survey (USGS) 7.5 minute quadrangle map sheets. Some watersheds drainage areas were defined for streams less than third order and some large area watershed were split to maintain a maximum size of 15,000 acres. The watershed boundaries in this file were developed in a joint state and federal effort to create a consistent watershed file for use by all government agencies with an interest in Maryland's watersheds. The U.S. Natural Resources Conservation Service (NRCS) redefined the third order watersheds creating the HUA14 file. This file contains all of the HUA14 watersheds and some added watersheds to maintain water quality sampling sites. It was also used to create the Maryland Sub-Watershed file.
