Project No: PS12.1

Title: Fixed season grazing of mountain paddocks in the karoo - Bergkamp
Project Leader: Dr PCV du Toit Starting date: 1943
Partners: Closing date: indefinite
 
Objectives: To illustrate to the farming community the detrimental effects that fixed seasonal grazing of specific paddocks can have on the vegetation, such as often happens on sheep farming enterprises, where certain paddocks are reserved for mating, lambing down and weaning, year after year as opposed to continuous rest
Location: Grootfontein
