Too many elephants in African parks?

Do high elephant numbers drive down total biodiversity, including other types of wildlife which tourists come to see?

International environmental organisations have been working in southern Africa for decades to support parks and conservation efforts in the communities adjacent to them. While these efforts have been beneficial in some areas, an obsession with the protection of certain high profile species, such as the African elephant, has actually been counter-productive in some cases. While the numbers of African elephants are declining globally - and these animals certainly deserve protection in many regions - in other areas their numbers are so high that they are causing overall declines in biodiversity.
Botswana's Chobe National Park covers approximately 11,000 square kilometres and has an estimated elephant herd of 70,000. International visitors to the park are often treated to an amazing scene of hundreds of elephants bathing in the Chobe River or frolicking on nearby plains. But biologists estimate that the park actually has seven times the number of elephants it can reasonably support over time. The result is a landscape within the park that is heavily degraded as elephants - while a delight to those on photo safari - are incredibly destructive as they uproot trees and trample vegetation. High elephant numbers also drive down total biodiversity, including other types of wildlife which tourists come to see.
International conservation agencies have been working with communities around the Chobe National Park to encourage the conservation of elephants. In exchange for cooperation in elephant conservation, local communities receive a share of ecotourism revenues as a reward and to compensate them for crop losses due to raiding elephants. While support and collaboration with local communities is good and only fair, especially considering the costs people endure by living close to wildlife, the goal of protecting elephants at all costs seems misguided in this situation.
...So why do international conservation organisations and some governments, like that of Botswana, persist in the excessive protection of some sub populations of elephants even when it is bad for biodiversity and local livelihoods? The answer varies from an irrational obsession with - and narrow focus on - certain high profile species, to a more legitimate concern that the culling, or controlled killing, of elephants in some areas may foster hunting in other areas where elephant numbers are low.
Animal rights activists also decry the killing of any wildlife, much less elephants which are known to have strong familial bonds and mourn the loss of deceased members. Still others believe that culling will depress ecotourism revenues, either directly through a diminished safari experience or, indirectly, when international protests over controlled elephant culling dissuade tourists from visiting certain countries.
...Global conservation organisations, some governments and ecotourists must move away from a paradigm of preservation at all costs of certain high profile species and adopt more of an ecosystem perspective. We must also realise that some species may be endangered or threatened at the international or regional scale, but actually exist in too high a number in some parks and conservation areas. This blindness to "too much of a good thing" is often detrimental to the livelihoods of rural people who live near parks, diminishes the ecotourism experience, and destroys biodiversity, the very objective of conservation.

  1. "Too many elephants in African parks?" Most certainly YES !
    "This blindness to "too much of a good thing" ......destroys biodiversity, the very objective of conservation." Well said Prof. Moseley !

    Each year I would take the family, for a week or so, to one of those lovely, remote, pretty basic, camps on the Zambezi river up from the Falls, Impala-Jena, Sansimba etc., AND each year I'd be horrified by the gradual disappearance of the unique riverine forest, the very thing or environment I'd travelled all that way to holiday in. Yes, I enjoyed seeing wild animals around whilst fishing, but, most of all, I relished the cool comfort of that forest, a totally different world to the harsh reality of the parched bush 50m beyond.

    It was obvious to any thinking person that elephants were causing this destruction. I started following reports of elephant populations in Zimbabwe national parks and, sure enough, as they increased so did the rate of riverine destruction.

    In the old days elephants were choosy about tree species they would damage, being content to coppice the mopani-veld outside the forest, but this seemed to change with time. Slowly they started tackling species in the riverine forest which had never been touched in the past. They broaden their pallet! Eventually I noticed them destroying species such as Terminalia which 10 years earlier never used to be touched. Was it that Terminalia were just the "Crumbs left on the plate" after the rest of the riparian forest had been consumed.
