Dataset of vegetation surveys on all islands (2007 - 2012) and on Mandarte Island (1986 & 2006)
In the first tab (vegetation surveys on all island 2007 - 2012) we included for every plot the data on number of species and cover of species, separated in exotic and native species groups. We give fraction of litter, rock, moss, lichens and bare ground cover. We give mean soil depth in the plot as well as % carbon and nitrogen in the soil sample of the plot. In the second and third tab (vegetation surveys Mandarte Island 1986 and 2006) we included for all plots on Mandarte Island the fraction of grass, rock and shrub cover, species cover specific (several species of plants) and soil depth.
