3.1 Identify the approximate dispersal distance of larvae of the impacted species

Action: 3.1 Identify the approximate dispersal distance of larvae of the impacted species

(e.g., see MLPA “Size and Spacing” guidelines)
Many marine organisms have a larval stage wherein individuals are dispersed along the coast by ocean tides and currents. The distance traveled depends on larval duration, larval behavior, and oceanographic dynamics. Size and spacing guidelines were developed through the Marine Life Protection Act process based on the estimated dispersal distances of many marine organisms. This information is important when permitting projects because impacts from an activity can affect the quality of habitat available for larvae when they settle out of the water column, as well as the survival of larvae in the water column.

Applying ecological principles

Ecological principles represent the core attributes of natural systems that must be maintained or restored in order to support healthy marine and coastal ecosystems, and include maintaining, restoring, or accounting for:

These principles are explained in a reference guide for agencies in California, called the Ecological Principles Guide . This guide also includes a series of case studies and checklists that demonstrate how the principles can be applied to day-to-day decision making.

State GeoPortal

The EcoPrinciples Connect tool links to data from the California Geoportal, which offers an easy and convenient way to search, discover and use authoritative geospatial data resources. This one-stop geospatial shop is helping to improve access to California’s geographic data portfolio and expand the use of those data resources in decision making processes.
