Marine Protected Areas (MPA) Project
Overview of project and Geoprocessing
What is an MPA?
An area set aside for conservation
www.mpa.org
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

MPA Definition Primary Conservation Goal
Natural Heritage Cultural Heritage Sustainable Production
Level of Protection No Access No Impact No Take Zoned With No-Take Areas Zoned Multiple Use Uniform Multiple Use
Permanence of Protection Permanent Conditional Temporary

Constancy of Protection Year-Round Seasonal Rolling
Scale of Protection Ecosystem Focal Resource
Allowed Extractive Activities Commercial Fishing Recreational Fishing Subsistence Hunting/Fishing Scientific/Educational
Collecting Mineral/Energy Extraction Other
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
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 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 ) http://www.dfg.ca.gov/mrd/mlma/index.html
California’s Fisheries
Pacific Fisheries Information Network (PacFin)
Fishery catch reported by the commercial industry
• Landings (lbs)• Species• Year• Location (10 nm
blocks)
http://www.psmfc.org/pacfin/overview.html
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:
Geoprocessing – in ArcTool Box Dissolve Merge Intersect Clip Buffers
Summarizing Tables Joining Tables Model Builder
Merge
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 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
Clip 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
This tool creates a new feature class of buffer polygons around either polygon, line, or point features.
Analysis Tools> Proximity > Buffer
Dissolve
This tool combines like features based on a specified attribute or attributes.
Data Management Tools> Generalization > Dissolve
