Networks represent an integrated system of

multiple protected areas

Often designed to:

- conserve regional biodiversity and ecosystem

function across habitats,

- buffer against catastrophes,

-! connect populations on ecological timescales,

- provide sustained socioeconomic benefits

Channel Islands National Marine Sanctuary

Channel Islands MPAs

Background

-! In April 2003, California Department of Fish and Game (CDFG) implemented new network of MPAs in state waters of the CINMS

-! This followed more than 4 years of public meetings, working group discussions and scientific analysis

-! In July 2007, these MPAs were extended into Federal waters

-! Channel Islands Zoning network is now the largest in continental US waters (total area 240 sq. nautical miles)

There is strong regional environmental variation

across the Channel Islands

-! MPA network encompasses this variation

-! This gradient can influence population and community attributes

(i.e., how fast individuals grow, where species occur and how

abundant they are)

Data from CALobster. Analysis by M. Kay, H.

Barsky

Some fish species spend most of their time

in reserves, others move more often

Data and analysis: J. Lindholm, A. Knight, D. Klein, M. Domeier and J. Caselle


Some commercial fisheries fared well,

others declined

Data: California Department of Fish and Game; Analysis: M. Bergen, D. Aseltine-Neilson, and C. Valle

Recreational fisheries shifted locations but

changes did not appear to be related to MPAs

Data: California Department of Fish and Game. Analysis: C. Ryan, L. McGarvie, S. Owen, W. Dunlap, and A. Sadrozinski

Conclusions

How does density, size structure and biomass vary throughout the CI MPA network?

There are consistent differences in abundance,

biomass, and size structure of targeted (i.e. FISHED)

fishes in the CI MPAs

How does species composition and food web structure differ throughout the CI MPA network?

Species composition, while not dramatically different

now, will likely continue to change for decades in the

reserves relative to outside, possibly altering the

trophic structure of MPAs

Conclusions

How does animals move in relation to MPAs?

Many reef organisms have small home ranges and

spend the majority of their time in MPAs. However,

individuals of these species can make larger

excursions.

How have fisheries changed throughout the CI MPA network?

Commercial and recreational fisheries have changed

since implementation of MPAs however, large losses to

most fisheries were not observed. Changes in these

fisheries are linked to environmental shifts, market

forces, and changes in fishery regulations.

1.! Protect natural diversity and ecosystem functions.

2.! Sustain and restore marine life populations.

3.! Improve recreational, educational, and study

opportunities.

4.! Protect representative and unique habitats.

5.! Clear objectives, effective management, adequate

enforcement, sound science.

6.! Ensure that MPAs are designed and managed as a network.
