Shrub demography 1988-1993

This package includes three worksheets, namely “BD8891”, “flowers” and “hosts”. The data are repeated measures of the basal stem diameters (1988-1991), flower production (1988-1993), and host plants of marked individuals of three shrub species (Pteronia empetrifolia, P. pallens and Tripteris sinuata) under two landuse histories and three levels of current herbivory. All marked plants were in permanent (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 1993. Spanning a period of 6 years the data have potential to show the effects of sheep grazing withdrawal on plant growth and reproductive potential for farms with different grazing histories. Note: Any publications, thesis, reports etc stemming from this data must be sent to SAEON Databank for records to be kept with the data.
