Conservation and Enforcement Capacity index (CECi): Integrating human development, economy, and marine turtle status

Human societies are closely linked to their ecological environments. Natural ecosystems and wildlife populations are often in better condition in countries with healthy, educated and economically prosperous populations compared to countries with lower health and literacy conditions, and depressed economies. In the latter countries, these socio-economic factors can compromise government's capacity to manage their natural resources. Thus, the conservation capacity of a government is likely to play key role in the protection of threatened species, such as marine turtles. This paper aims: (1) to evaluate the conservation capacity and enforcement within the 58 Regional Management Units (RMUs) of the seven species of marine turtles throughout the world, and (2) to develop a proxy that predicts the conservation status of RMUs. We developed a Conservation and Enforcement Capacity index (CECi) by integrating the following indices: (a) the economic level and, (b) the Human Development Index (HDI) of each country, plus (c) the risks and threats in the RMUs. We used the conservation status of 15 RMUs recently assessed by the International Union for Conservation of Nature - IUCN to predict the conservation status of the 43 RMUs without updated IUCN categorisation. CECi values ranged from 0 to 1, where lower values represent a better capacity for implementation of conservation initiatives. We found that using our multi-index model, we predicted the status of 33 of 58 RMUs, 57% of which may be of threatened conservation status due to their high CECi values. This study highlighted how socio-economic aspects may impact conservation of endangered species.
