Habitat Fragmentation Threatens Chile’s Güiña Wildcat More Than Human Persecution

The güiña has a reputation for attacking livestock and, therefore, is perceived negatively by rural inhabitants in the region. As a result, it had been assumed that a major threat to the future of the güiña was human persecution, coupled with extensive farming and logging that has seen its habitat reduced by almost 70% since 1970.

However, through a series of questionnaires, camera trap data and remote-sensed images the researchers, led by Nicolás Gálvez studying at the Durrell Institute of Conservation and Ecology (DICE), found that the güiña is remarkably adaptable to forest loss.

In particular the team found that large, intensive agricultural areas are actually well suited for the güiña and should not be dismissed as poor quality habitat. This is because there are often unfarmed areas that provide refuge, food resources and suitable conditions for rearing young.

Dr Nicolás Gálvez, now a lecturer at the Pontificia Universidad Católica de Chile, commented: “Land subdivision and fragmentation have a far bigger impact on güiña survival. This is because there is a higher risk of human interaction and persecution in areas where there are more farms, a greater pressure on natural resources through increased timber extraction and livestock grazing, and even competition for food from domestic animals kept as pets.”

Professor Zoe Davies, from DICE at Kent, said: “Notably, though, while the risk of a güiña being killed by a human is higher in more densely populated farming areas, our questionnaires indicate that only 10% of the rural inhabitants have killed a güiña over the last decade. This suggests that persecution is much less of a threat to their survival than the subdivision of farms.”

As a result of this, the researchers suggested that farmers with large properties are key stakeholders in the conservation of this species and must be at the centre of any conservation interventions that aim to protect existing land where the güiña is usually found.

The findings also highlight a framework that can be used to spatially match social and ecological data which could help with conservation efforts for other similar small to medium sized carnivores in other parts of the world. The framework provides a clearer understanding of how habitat loss, land fragmentation and human interactions affect species survival.
