Marine Protected Areas (MPA) Project

Overview of project and Geoprocessing

What is an mpa l.jpg

What is an MPA?

An area set aside for conservation

Mpa definition l.jpg

MPA Definition

  • Federal Definition

  • MPA is a general term for places given special protections for natural or historic marine resources by local, state, federal or tribal authorities national parks

    • wildlife refuges

    • Monuments

    • marine sanctuaries

    • fisheries closures

    • critical habitat

    • habitat areas of particular concern

    • state parks,

    • conservation areas

      estuarine reserves and preserves

Fisheries management tools l.jpg

Fisheries management tools

  • Management tools for fisheries

    • Quotas – how many

    • Size limits – how big

    • Gear restrictions – trawling prohibited within shoreline to 3 mi

    • Time based restrictions

    • Spatially (place) based –

      • Rockfish conservation areas

      • Cowcod conservation areas

      • Marine protected areas

California s mpas marine life management act l.jpg

California's MPAs - Marine Life Management Act

  • 1999 - California State Legislature direct the state to design a network marine protected areas

  • MPA – six classifications

    • State Marine Reserves

      • No take

    • State Marine Park

      • Some recreational fishing allowed

    • State Marine Conservation Areas

      • Some recreational and commercial fishing allowed

California s mpas marine life management act7 l.jpg

California's MPAs - Marine Life Management Act

  • Central Coast Project (Point Conception to Pigeon Point)

    • Proposed network of MPAs from Point Conception to Pigeon Point by 2006

    • Rest of the coast between 2006-2011

    • Public input critical!

    • Stakeholders (recreational angling and diving, commercial fishing, ports and harbors, conservation, business )

California s fisheries l.jpg

California’s Fisheries

  • Pacific Fisheries Information Network (PacFin)

    • Fishery catch reported by the commercial industry

      • Landings (lbs)

      • Species

      • Year

      • Location (10 nm blocks)

Your mission is to select mpas that consists 1 and 2 contiguous fishing blocks that l.jpg

Your mission is to select MPAs that consists 1 and 2 contiguous fishing blocks that:

  • Have a depth equal to or less than 1200 m

  • The bottom substrate is either hard or mixed

  • Is more than 25 nautical miles from Moss Landing and Morro Bay

  • Will not heavily impact fishers

New tools you will use l.jpg

New Tools you will use:

  • Geoprocessing – in ArcTool Box

    • Dissolve

    • Merge

    • Intersect

    • Clip

    • Buffers

  • Summarizing Tables

  • Joining Tables

  • Model Builder

Merge l.jpg

Combines input features from multiple input sources (of the same data type) into a single, new, output feature class. The input data sources may be point, line, or polygon feature classes or tables.


Data Management Tools> General > Merge

Intersect l.jpg


This tool builds a new feature class from the intersecting features common in both feature classes. It retains the attributes of both feature classes.

Analysis Tools> Overlay > Intersect

Slide13 l.jpg


  • This tool uses a polygon boundary to cut features and their attributes from a feature class.

Works like a cookie cutter.

Analysis Tools> Extract > Clip

Buffer l.jpg


  • This tool creates a new feature class of buffer polygons around either polygon, line, or point features.

Analysis Tools> Proximity > Buffer

Dissolve l.jpg


  • This tool combines like features based on a specified attribute or attributes.

Data Management Tools> Generalization > Dissolve
