Non-lethal elephant population control methods: Summary of the first workshop of the Elephant Specialist Advisory Group of South Africa

Abstract

Management interventions are necessary to control elephant numbers within fenced wildlife reserves in South Africa. Use of non-lethal control methods is increasing, but information about their suitability and effects are not widely available. Three such methods are currently available: immunocontraception with porcine zona pellucida vaccine, vasectomy and gonadotropin-releasing hormone vaccine. Here we consolidate what we know about these methods, using published sources and material shared at a workshop held in South Africa in 2016, in order to provide up-to-date information for future policy decisions concerning the use of these methods in South Africa and elsewhere.
