Wetlands or other mapped features may have changed since the date of the imagery or eld work. There <br />may be occasional dierences in polygon boundaries or classications between the information depicted <br />on the map and the actual conditions on site. <br />Data exclusions <br />Certain wetland habitats are excluded from the National mapping program because of the limitations of <br />aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or <br />submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and <br />nearshore coastal waters. Some deepwater reef communities (coral or tubercid worm reefs) have also <br />been excluded from the inventory. These habitats, because of their depth, go undetected by aerial <br />imagery. <br />Data precautions <br />Federal, state, and local regulatory agencies with jurisdiction over wetlands may dene and describe <br />wetlands in a dierent manner than that used in this inventory. There is no attempt, in either the design or <br />products of this inventory, to dene the limits of proprietary jurisdiction of any Federal, state, or local <br />government or to establish the geographical scope of the regulatory programs of government agencies. <br />Persons intending to engage in activities involving modications within or adjacent to wetland areas should <br />seek the advice of appropriate Federal, state, or local agencies concerning specied agency regulatory <br />programs and proprietary jurisdictions that may aect such activities.
