The Kruger National Park in South Africa faces a major dilemma. It currently contains about 7500 more elephants that it can sustain long term. As elephants are renowned for their destructive browsing, they tend push trees over before eating the leaves; something has to be done to regain the ecological balance.
The options seem to be
1/ Contraception; has been tried before and worked with limited but reasonable success, the main problem being the long life span of the elephant. i.e. no more babies for a few years, but still a very high density of elephants for a good few years to come.
2/Translocation. Now far too many elephants to move.
3/ Cross border parks. Still struggling with the politics.
4/ A mass cull. Apparently effective if the ENTIRE herd is culled. Limiting grieving on loss of others.
I think that we have to agree that even in the most wild of places, mans intervention over hundreds if not thousands of years, political borders not recognised by wild life etc. means that we have a to manage these animals and their habitat with as little intervention as possible to ensure their survival for generations to come. .
What do others think should be done to correct this situation? WW
