Population Dynamics of Mountain Zebra, Gemsbok, and Springbok in Gondwana Cañon Park 2007

In 2007, a population estimate of the Mountain Zebra in Gondwana Cañon Park revealed significant movement patterns in response to climatic variability. High rainfall in 2006 led to westward migration, while the current dry conditions prompted a return eastward, indicating a growing population. Gemsbok numbers have increased to around 1,000, and Springbok populations rose from 500 to approximately 3,600, aided by fence removals that enhance mobility and habitat diversity. The Kudu and Ostrich populations have also benefited from better environmental conditions.

  1. OBJECTIVES OF COUNTING 2007 Game Count in the Gondwana Cañon Park

  2. Mountain zebra– population estimate In 2006 (high rainfall year) Mnt Zebra moved westwards into the mountainous areas of the Fish River Canyon and Huns Mountains, with significant numbers leaving the GCP. This year (2007), with the dry conditions, animals moved eastwards back into GCP. Reflects both a growing population and extensive movement patterns in response to rainfall. Fence removals have allowed this mobility and natural responses to climatic variability – and thus overall more healthy populations.

  3. Gemsbok - Population estimate Gemsbok populations continue to increase following the good rainfall year of 2006. Carrying capacity for the GCP is estimated at about 1,000 gemsbok.

  4. Springbok– population estimate Springbok numbers have increased over the years (from a starter population of some 500 animals) to the current population of some 3,600 animals. The overall increase has probably been larger than reflected here in the 2007 count, because of animals disbursing into neighbouring areas (particularly the Ai-Ais National Park) as a result of orad fence fence removals within the GCP. This has created a more diverse set f habitats and the overall numbers and condition f animals is expected to improve as a result.

  5. Kudu– population estimate

  6. Ostrich – population estimate Ostrich populations often increase rapidly in response to good environmental conditions. This has occurred in the GCP following the good rains of 2006.

  7. Gemsbok distribution Increasing and expanding populations of Gemsbok in the GCP, starting at some 30 animals in 1988 and estimated as some 620 in 2007

  8. Springbok distribution Removal of road fences have allowed Springbok to move into areas not previously occupied by them, and to move back and forth seasonally in response to rainfall and grazing
