3.3.1 Ecology
Human populations and activities both within and around the MMNR have increased dramatically over recent decades. These pressures on the Reserve range from internal factors such as high visitor densities impacting on the Reserve’s habitats and wildlife, to even more profound long-term external factors, such as diminishing quantities and erratic flow of water in the Mara River, the lifeline of the Reserve, and changing land use practices, such as conversion to wheat farming in the north of the ecosystem, which is eroding the dispersal areas and migration corridors that are critical to the survival of the Reserve’s wildlife. The scale of these pressures is such that concerted action by Reserve managers and other stakeholders is now urgently needed, which is the major function of the Ecological Management Programme.
Although long-term ecological change is a natural and important aspect of the Mara-Serengeti Ecosystem, human activities and impacts, particularly in the greater ecosystem beyond the MMNR’s boundary, have dramatically increased over recent decades, and in some cases have already substantially impacted on the area’s ecology. This is perhaps most evident in the significant decline of migratory species in the Kenyan part of the ecosystem, and also in the potentially ecologically destructive reduction of water levels in the Mara River. At the same time, pressures from tourism development and visitor use within the Mara Reserve have also greatly intensified, which unless appropriately managed have the potential to seriously impact on the ecology of the Reserve itself, and to undermine the very resources that make the area so attractive to visitors.
Managing these and other human-induced changes impacting on the MMNR’s ecology, and balancing the competing needs of resource conservation and use, are arguably the greatest challenges facing the management of the MMNR today. The Ecological Management Programme will play a crucial role in spearheading management responses to these issues, not only by providing the ecological information that is needed to better understand the underlying facts driving these impacts, but also by leading the implementation and adaptation of management interventions designed to address the most significant threats to the area’s exceptional natural resources.
To address these issues, the Programme first identifies the most important and representative biological features of the Reserve’s ecosystem – called the Conservation Targets - including the key species and habitats that are represented in the Reserve, as well as the system-level features that are critical to the Reserve. The programme then identifies the key ecological attributes that are vital to maintaining the conservation targets, as well as the critical threats impacting on the targets. This information is then used as a basis for the development of the Programme’s management objectives and actions, with the aim of ensuring that management attention is focusing on the most important biological components of the Reserve and the most important threats impacting on them.
The guiding principles that describe key factors taken into account in the development of the Ecological Management Programme, and that will influence the way the programme is implemented and the achievement of the Programme Purpose.
The four guiding principles for the Ecological Management Programme are:
  • Sustaining the MMNR’s critical role at the heart of the greater Mara-Serengeti Ecosystem
  • Maintaining a careful balance between the conservation and use of natural resources
  • Enhancing collaboration and cooperation in ecosystem management
  • Strengthening practical management through improved ecological monitoring and research
