Management options to minimise formation of urchin barrens: assessing dynamics of incipient urchin barrens patches in eastern Tasmania using timed swims
Timed GPS-tracked swims using SCUBA (45 and 30 minutes), were used to assess the changes in frequency and size of Centrostephanus rodgerii incipient barrens in eastern Tasmania. The number of C. rodgerii and Heliocidaris erythrogramma in each incipient barren were also assessed.
