Description

An interesting dichotomy exists for canopy kelp habitat (Bull kelp, Nereocystis luetkeana) in Washington State. Canopy kelp beds on the coast, Strait of Juan de Fuca are understood to persist in abundance while within Puget Sound major declines in floating canopy kelp have been documented. Losses in Puget Sound and elsewhere have captured the interest of restoration practitioners working to re-establish imperiled marine species and habitats. The consequences of these declines are not limited to the direct effects on kelp populations, but also to the many species that utilize this habitat. The Puget Sound Restoration Fund is actively working to develop enhancement practices that will restore natural recruitment of Nereocystis to discrete locations and, through scaled or repeated treatments, facilitate the persistence of re-introduced canopy kelp to historic areas. Recent work includes experimental outplants at historic kelp sites in Puget Sound. Kelp propagation and cultivation methods are well described, but enhancements intended for restoration impose special constraints to otherwise straight-forward algae production. This talk will focus on the status of that research to develop successful enhancement practices for this habitat form.
