Indian River Lagoon
Aerial Photography
Type: Extent of habitat (i.e., area of habitat
and whether there has been a decline).
Category: Submerged, Intertidal, Wetland, and Upland
Cost: $75,000
Description: This study included collecting, reviewing,
and interpreting historic aerial photography to establish baseline
conditions for pollutant loadings and the extent of wetlands and
seagrasses. The project used 1943 aerial photographs of the Indian
River Lagoon basin north of Fort Pierce. The photographs were
used to determine land cover/land use, wetland acreage, and acreage
of seagrasses. A GIS-based model (Pollutant Loading Screening
Model) was used to estimate pollutant loadings from 1943 land
cover/land use to the Indian River Lagoon in 1943.
Outcome: The 1943 aerial photographs provided the
best available record of historical conditions in the Indian River
Lagoon basin. They were used to establish baseline conditions
for seagrass acreage and pollutant loadings. These baseline conditions
have been set as the goals for the Indian River Lagoon for reductions
in pollutant loadings and increases in seagrass acreage.
