    A summary of the Tristan Biomass Index Survey results to date
    (2012) Johnston, Susan
    A number (12) of biomass surveys has been completed thus far at each of the four islands of the Tristan da Cunha group. Table 1 provides the months during which each of these surveys was undertaken at each of the four islands. For each season there is usually a Leg 1 survey carried out at around Aug/Sept and then a further Leg 2 survey conducted around Feb/Mar. This document aims to provide a brief summary of the biomass index data collected thus far.
