High Quality Content by WIKIPEDIA articles! The Marine Life Protection Act (MLPA) was passed in 1999 and is part of the California Fish and Game Code. The MLPA requires California to reevaluate all existing marine protected areas (MPAs) and potentially design new MPAs that together function as a statewide network. The MLPA has clear guidance associated with the development of this MPA network. MPAs are developed on a regional basis with MLPA and MPA specific goals in mind, and are evaluated over time to assess their effectiveness for meeting these goals.
