Lease: California Kelp Research
Location
Central Coast, California, USA
Description
This case study presents an example of leasing subtidal kelp forests for scientific research purposes. The Nature Conservancy (TNC) has leased two kelp beds (totaling four square miles) off the coast of California for research and conservation purposes. These beds include approximately 1,700 acres of kelp along 15 miles of the Big Sur coast.
There are 89 state-defined kelp beds along the California coast. The kelp beds are designated as no-take areas, open harvest areas, and areas eligible for leasing. While 38 kelp beds are available for lease, only 9 are currently leased, 2 by TNC and 7 by abalone farmers. Historically, the major commercial leaseholder (ISP Alginates) harvested kelp for algin. Kelp leases are now used solely for obtaining kelp for abalone aquaculture feed.
In 2004, TNC sought to lease one kelp bed from the state and to sublease another bed from ISP Alginates (then the state’s largest kelp leaseholder) in order to examine the nursery role of kelp forests and their canopies for rockfish and other marine species. Envisioned as a California test case for marine research and conservation leasing, the study required permission for experimental manipulation, as well as the establishment of control sites. ISP agreed to sublease Kelp Bed 209, and the California Fish and Game Commission (FGC) agreed to lease bed 214 to TNC.

Researchers at TNC and the University of California - Santa Cruz (UCSC) used both leases for the purpose of experimentally removing kelp canopies and examining the impacts on kelp communities. They sought to determine whether the removal of kelp canopies affected biodiversity and how any detrimental impacts might be reduced.
Subsequently, ISP decided to cease harvesting in California and chose not to renew any of its leases. TNC applied to the FGC to lease bed 209 directly, and the FGC again granted approval of the leases. The researchers have worked successfully in partnership with the largest remaining harvester, The Abalone Farm Inc.

Lessons Learned
- Leases can be used to foster research partnerships.
- Tracking kelp leases is not a high priority for the state.
- During the Marine Life Protection Act process (a state MPA process) many managers and stakeholders were surprised to learn that proprietary rights previously granted by the state often trump most other forms of management.
Cost Summary
In addition to lease costs of approximately $5,800, research costs have been about $100,000 per year.
