Research

The Cape Leopard Trust (CLT) is an environmental NGO and non-profit, founded in 2004 and based in the Western Cape, South Africa. Our mission is to protect leopards and leopard landscapes, and support coexistence between humans and wildlife, through collaborative research, conservation, education and strategic communications.

The Cape Leopard Trust (CLT) is a research-based organisation that utilises a variety of biological and social science research techniques to better understand leopard ecology and how humans interact with leopards. By gathering robust data, we can make informed decisions and recommendations based on scientific fact.

The initial focus of the CLT’s work during its first 15 years was to establish a comprehensive baseline of leopard research in certain core areas within the Western Cape, with camera trapping, diet analysis, and leopard collaring and tracking comprising the main activities. We’ve learnt that leopards occur at comparatively low population densities across the province; that they generally take small to medium-sized prey in proportion to what is most available in the habitat; and that they patrol vast home ranges, in some cases up to tenfold larger than in the Savanna biome.

But this was just the beginning of what’s needed to ensure the health and viability of the leopard population in the Cape. The thrust of our current and future research is to expand our work to a broader landscape level, to monitor leopard populations across regions and to contribute to applied management policy at a broad scale.

Monitoring leopard density and population trends

Repeat large-scale camera surveys to determine and monitor leopard population trends over time is a major part of this approach. The focus is on several core monitoring areas including the Cederberg wilderness, Piketberg and Olifantsrivier mountains, Boland Mountain Complex, Overberg region as well as the Little Karoo. These surveys cover huge areas of between 1500 – 3500 km2 and utilise between 120 – 180 camera traps placed in paired stations across these landscapes. Each survey runs for several months and delivers hundreds of thousands of images which then get uploaded, sorted, identified, and analysed to ultimately provide an estimate of leopard population density in an area. The non-leopard photos are equally useful and are submitted to various databases and utilised in by-catch studies.

Building a consolidated centralised leopard database

We are also examining where leopards are present across the Western Cape, as well as identifying areas where they are under pressure. We have established a comprehensive leopard database encompassing the Western, Northern and Eastern Cape, which incorporates data from research institutions, statutory nature conservation bodies and hundreds of private contributors. The addition of data is ongoing to encourage continued citizen science involvement and expand leopard distribution knowledge. Using the online CLT ‘Leopard Data Portal’, data can be submitted to one of three purpose-built platforms, namely ‘Leopard Spotter’, ‘Threat Tracker’ and ‘Snare Aware’.

Identifying and protecting leopard movement corridors

We’ve conducted a province-wide occupancy analysis and modelled a fine-scale leopard habitat suitability map. We used connectivity modelling to further map potential leopard movement pathways between core habitats across the region. Results from this research provide insights into suitable areas for potential ecological corridors for leopards and can inform future camera trapping surveys (aimed at long-term population monitoring). Protecting this connectivity across broad, transformed landscapes is essential for many species’ survival, especially wide-ranging species like leopards, and is a core activity for our efforts into the future. This includes a toolkit currently under development that collates all of our modelling into GIS layers that can be used as a measure of decision-making by EIA practitioners and land planning units.

Embracing social science

To broaden our understanding of anthropogenic pressures on leopard landscapes, as well as people’s perceptions of and attitudes towards leopards, we’ve stepped into the social science sphere. Utilising questionnaire-based research into the threats faced by leopards and other predators we investigated farmer attitudes, experiences and predator control strategies within and bordering the Western Cape and what these interactions mean for conservation and agriculture. A questionnaire study using Local Ecological Knowledge was used to explore people’s perceptions of mammal occurrence and abundance on agricultural properties, and we’ve used similar questionnaire-based approaches to investigate the prevalence and drivers of snaring as well as to quantify the use of animal parts in traditional medicine and cultural applications.

Disseminating our learnings

Publishing our findings in peer-reviewed scientific journals is a key output for our research team, as scientific publications are vital to consistently improve the strategic management of the ecosystems and landscapes in which we work. Staff, students and associates of the CLT have authored, co-authored and enabled a large number of academic papers, a full list of which is available on our Publications page. A major achievement was also the inaugural Global Leopard Conference in 2023, a virtual gathering of the world’s leading leopard scientists and conservationists. The conference was conceived and driven by the CLT, ignited by our ambition to enhance leopard conservation through international dialogue and learning exchanges. In collaboration with several international conservation organisations, we co-hosted an inclusive five-day virtual conference which provided a platform to share leopard conservation lessons and promote collaborative solutions.
