As one of the world’s most iconic and charismatic megafauna, the lion, Panthera leo, is a species whose conservation attracts international concern from conservationists and the global public alike. However, lion range and numbers have declined markedly over the last two decades.

In a recent publication in the journal Nature Conservation, two members of the Tilburg Environmental Law Team (Arie Trouwborst and Melissa Lewis) collaborated with biologists and social scientists from the University of Oxford’s Wildlife Conservation Research Unit  (WildCRU) to assess the present and potential future role of international wildlife treaties in lion conservation.

Like other species of large carnivores, lions present a special set of conservation issues from a legal perspective due to their great spatial requirements, elevated human-wildlife conflict potential, and role as both keystone and umbrella species. For these reasons, and because of the transboundary nature of many lion populations and some of their threats, international law plays a distinct role.

Lion conservation has featured prominently on the agendas of certain wildlife treaties – including the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and, more recently, the Convention on the Conservation of Migratory Species of Wild Animals (CMS). In October this year, for instance, Parties to the latter Convention will decide whether to list the lion on one of the CMS’s appendices, and will further consider the adoption of several draft decisions of significance for lions and other African carnivores. Although sometimes less obvious, a range of other treaties also play a role in the endeavor to conserve the world’s remaining lion populations. For instance, 39 of the sites that are currently designated as Wetlands of International Importance under the Ramsar Convention, and 18 of the areas that have been designated as World Heritage Sites under the World Heritage Convention, are of actual or potential significance to lions.  A myriad of regional instruments are also relevant – examples including the African Convention on the Conservation of Nature and Natural Resources, the SADC Protocol on Wildlife Conservation and Law Enforcement, the various treaties establishing transfrontier conservation areas (TFCAs), and even the Bern Convention on the Conservation of European Wildlife and Natural Habitats.

In this paper, we identify not only a substantial body of relevant international wildlife law, but also a significant potential for enhancing these instruments’ contribution to lion conservation. We argue that the time is right to invest in such improvements, and we provide both general and treaty-specific recommendations for doing so. With the 2017 CMS Conference of the Parties fast approaching, the paper’s support for augmenting this Convention’s role in lion conservation is especially noteworthy. The paper concludes that:

“Given the fragmented collection of treaties which currently apply to lions and the absence of adequate international instruments and/or institutions for lion conservation in at least portions of the species’ range, an important role appears, in principle, to be reserved for the CMS, both in terms of coordination and gap-filling. Listing lions under the Convention would be a logical step in this regard … [and] would both signal the need to develop more elaborate species-specific frameworks for lion conservation and sustainable use and increase the avenues available for achieving this.”

It further provides recommendations for making optimal use of the Ramsar and World Heritage Conventions and TFCA agreements in sites of importance to lions; outlines possibilities for adjusting CITES’ restrictions on the trade in lions and their parts; and emphasizes the importance of maximizing range states’ participation in, and compliance with, wildlife treaties, and of promoting strategies which involve the local people who live alongside lions.
