A map of the shoreline vegetation in Ganges Harbour and vicinity was prepared from aerial photographs of this region taken in July 1975. Just prior to the 1977 herring spawning season, an underwater survey of vegetation in Ganges Harbour was undertaken by divers to ground-check the map. The divers found a large amount of loose drifting vegetation in this area which would not have been distinguishable from rooted vegetation in aerial photographs. Also, in some locations the rooted vegetation was so sparse (as low as 1% cover) that it was either misidentified or missed altogether in interpreting the aerial photographs. In spite of these problems (which were probably unusually acute in this area) the vegetation map prepared from aerial photographs was generally accurate and provided a satisfactory basis for assessing the distribution and abundance of herring egg depositions"--Abstract, page iii. |
