Abstract:

The first draft of this feature class was created in 2008 by the contractor Avineon, Inc. This feature class was improved in 2010 by incoporating new high-resolution side scan sonar data and 2054 field data points. Additional edits were made in August 2011 to ensure that this benthic habitat map would merge seamlessly with the 2010 vegetation map for the islands of Dry Tortugas National Park. To this end, the shapes of the islands were updated to reflect those in the 2010 vegetation map. For more information please see the final report: For more information please read the final project report: Waara, Robert J., Judd M. Patterson, Andrea J. Atkinson, Andrew J. Estep. 2011. Development and policy applications of the 2010 benthic habitat map for Dry Tortugas National Park. Natural Resource Technical Report NPS/SFCN/NRTR—2011/474. National Park Service, Fort Collins, Colorado.

Purpose:

The new benthic habitat map and corresponding products will help in showing what types of marine habitats are located in the Dry Tortugas National Park and provide the ability to track whether management interventions are effectively protecting the environment and associated resources.

Attribute_Domain_Values:

Enumerated_Domain:

Enumerated_Domain_Value: Unconsolidated Sediments

Enumerated_Domain_Value_Definition:

Unconsolidated sediments with less than 10 percent colonization by Submerged Aquatic Vegetation (SAV) or corals.

Enumerated_Domain:

Enumerated_Domain_Value: Continuous SRV

Enumerated_Domain_Value_Definition:

Submersed Rooted Vascular Plants (SRV) (i.e. seagrasses and oligohaline grasses) in continuous beds of any shoot density (i.e. sparse continuous, dense continuous or any combination). These areas appear as continuous seagrass signatures; however, small (less than 0.5 acres) bare sediment areas may be observed as infrequent features within the area.

Enumerated_Domain:

Enumerated_Domain_Value: Discontinuous SRV

Enumerated_Domain_Value_Definition:

Areas of Submersed Rooted Vascular Plants (SRV) (i.e. seagrasses and oligohaline grasses) with breaks in coverage that result in isolated patches of SRV, usually in unconsolidated bottom but also exist in hard bottom areas. If the hardbottom is more abundant than the SRV the polygon should be recorded as Reef/Hardbottom Class and SRV can be noted with Modifiers. Generally, these grass features appear as semi-round patches or elongated strands separated by bare sediment.

Enumerated_Domain:

Enumerated_Domain_Value: Reef Terrace (high profile)

Enumerated_Domain_Value_Definition: Contiguous reef with high complexity and high relief (>2m).

Enumerated_Domain:

Enumerated_Domain_Value: Remnant (low profile)

Enumerated_Domain_Value_Definition:

Reefs of relief less than 2m that lack distinctive spur and groove characteristics. These reefs consist of coral and hard bottom features; often support soft corals, sponges, seagrass; and are usually found growing parallel to the reef tract, though they may form transverse features that grow perpendicular to the reef tract.

Enumerated_Domain:

Enumerated_Domain_Value: High Relief Spur and Groove

Enumerated_Domain_Value_Definition:

Distinct coral bands separated by sand or uncolonized hardbottom grooves. The coral bands have 1.5- 4m relief.

Enumerated_Domain:

Enumerated_Domain_Value: Low Relief Spur and Groove

Enumerated_Domain_Value_Definition:

Distinct coral bands oriented perpendicular to the shore or bank and separated by sand or uncolonized hardbottom grooves. The coral bands have <1.5m relief.

Enumerated_Domain:

Enumerated_Domain_Value: Reef Rubble

Enumerated_Domain_Value_Definition:

Dead, unstable coral rubble that often occurs landward of platform reefs.

Enumerated_Domain:

Enumerated_Domain_Value: Aggregated Patch Reefs

Enumerated_Domain_Value_Definition:

High complexity patch reefs that have high relief (up to 15m) from the sea floor. These structures may occur in clusters and are typically surrounded by large sand plains. Includes Halo areas if present. Patch reefs in general are irregularly shaped reef communities. They may range in size from tens to thousands of square meters. Patches are separated from each other by uncolonized hardbottom, sand, or colonized substrate with submersed aquatic vegetation (SAV), macroalgae, gorgonians or sponges. Most often the patches are surrounded by a halo of bare substrate created by foraging, obligate reef inhabitants.

Enumerated_Domain:

Enumerated_Domain_Value: Individual Patch Reef

Enumerated_Domain_Value_Definition:

Isolated, single patch reef (larger than the minimum mapping unit of the project) without associated halo area. These individual reefs may have an associated halo, however if large enough (i.e. greater than the minimum mapping unit) to be delineated the halo will be mapped as its own subclass. Patch reefs in general are irregularly shaped reef communities. They may range in size from tens to thousands of square meters. Patches are separated from each other by uncolonized hardbottom, sand, or colonized substrate with submersed aquatic vegetation (SAV), macroalgae, gorgonians or sponges. Most often the patches are surrounded by a halo of bare substrate created by foraging, obligate reef inhabitants.

Enumerated_Domain:

Enumerated_Domain_Value: Patchy Coral and/or Rock in Unconsolidated Bottom

Enumerated_Domain_Value_Definition:

Areas of primarily sand, submerged aquatic vegetation (SAV), or low relief rock covered with a sand veneer. Often adjacent to spur and groove habitats, these areas contain small, individual corals or rocks that are distinctive yet a very low percentage of the total cover (and certainly smaller than the minimum mapping unit).

Enumerated_Domain:

Enumerated_Domain_Value: Pavement

Enumerated_Domain_Value_Definition:

Flat, low relief, mostly solid rock substrate (i.e. low relief hardbottom).

Enumerated_Domain:

Enumerated_Domain_Value: Land

Enumerated_Domain_Value_Definition: Terrestrial areas of map.

Attribute:

Attribute_Label: Shape_Leng

Attribute:

Attribute_Label: Island

Attribute_Definition: Island name, if appropriate.
