Species Cover 1988-2006, Tierberg Karoo Research Centre

The data are projected canopy cover values (metres and percentages) and densities (counts of plants) in 5 m x 5 m plots in indigenous Prince Albert Succulent Karoo vegetation on Tierberg Karoo Research Centre (TKRC) and on the adjacent farms Argentina (ARG) and Tierberg (TBG). The data collection began in November 1988, 17 months after TKRC was stock-fenced to exclude sheep. Thereafter data were collected intermittently until June 2006. Spanning a period of18 years the data have potential to show the effects of sheep grazing withdrawal on vegetation composition for farms with different grazing histories. This package includes three worksheets, namely “Sppcov 1988-2006”, “Totcov 1988-2006” and “Density 1988-2005”.
