EVC/Bioregion Benchmark for Vegetation Quality Assessment Glenelg Plain bioregion EVC 155: Bird Colony Succulent Herbland Description: A closed, succulent herbland (to open herbland during bird nesting season) occurring on coastal sand. Almost entirely restricted to offshore seabird breeding colonies. The nutrient enriched sandy substrates are dominated by the succulent herb Bower Tetragonia implexicoma Spinach and other succulent herbs.
