    Using Geographic Information Systems and remote sensing to improve the management of kelp resources in South Africa
    (2006) Rand, Andrew M; Bolton, John J; Anderson, R J; Butcher, Shirley
    In 2002 the Department of Environmental Affairs and Tourism (DEA&T), Marine and Coastal Management (M&CM) and the Seaweed Unit undertook a program to document the localities and quantities of the standing crop of the economically important kelps, Ecklonia maxima and Laminaria pallida, in the fourteen commercial seaweed Concession Areas that contain commercial quantities of kelps. The primary objective of this study was to establish a coastal kelp resource database for the South African coastline from Cape Agulhas to the Orange River (the international border with Namibia). The method was designed to integrate past and current analysis of multi-year kelp data from commercial harvesting, biomass and kelp bed extent while allowing for the integration of future surveys within the inventories.
