Habitat Restoration: Southern California Riparian Ecological Assessment Model (SCREAM)

What is SCREAM?

The Southern California Riparian Ecological Assessment Model, or SCREAM, assists the Southern California Wetland Recovery Project in identifying restoration priorities in Southern California. SCREAM is a decision-support tool that uses geographic information system (GIS) technology to assess riparian condition by calculating the functional contributions of habitat, hydrology, and biogeochemistry to the watershed. The model functions at a landscape scale, but scores riparian condition within a smaller, user-defined area. Scoring allows the user to rank or prioritize areas for restoration according to the assessed conditions.

Metric components of SCREAM

SCREAM was developed specifically for the Southern California landscape.

Model Requirements

SCREAM is an ArcGIS 9x extension that requires Spatial Analyst. A digital elevation model, stream network, and flow direction grid are required for initial processing. Metric scoring is dependent on user-provided remote sensing and field data.

For More Information

SCREAM was developed collaboratively by the NOAA Coastal Services Center and the Southern California Coastal Water Research Project. The model is currently being field-tested and calibrated in southern California.
