Management options to minimise formation of urchin barrens: kelp lines - assessment of changes in kelp growth at the kelp-barren interface
Linear video transects (40m total length; 20m into barrens and 20m into kelp from original fixed marker on the benthos) were used to assess changes in kelp growth in several points along the kelp - urchin barren interface in north-east Tasmania (St. Helens Island, Sloop Rock and Elephant Rock research areas). The video transects were deployed in the same position, and assessed at different points of time. The video was analysed in the laboratory to assess percentage of kelp and barren cover, as well as the kind of substratum, kelp species identifiable and number of sea urchins (Centrostephanus rodgerii and Heliocidaris erythrogramma) and other benthic organisms when present (rock lobster and abalone).
