“…Many countries have legislation that legally protects carnivores such as wolves (Canis lupis) in the United States of America and India [25], but killings continue, making protected carnivore persecution an issue of global conservation concern [23,26]. Illegal carnivore persecution has been measured indirectly in different ways [27,28], but such indirect methods tell us little about the characteristics of the people persecuting carnivores making it difficult to target interventions aimed at reducing carnivore killing.…”

Identifying indicators of illegal behaviour: carnivore killing in human-managed landscapes

Managing natural resources often depends on influencing people's behaviour, however effectively targeting interventions to discourage environmentally harmful behaviours is challenging because those involved may be unwilling to identify themselves. Non-sensitive indicators of sensitive behaviours are therefore needed. Previous studies have investigated people's attitudes, assuming attitudes reflect behaviour. There has also been interest in using people's estimates of the proportion of their peers involved in sensitive behaviours to identify those involved, since people tend to assume that others behave like themselves. However, there has been little attempt to test the potential of such indicators. We use the randomized response technique (RRT), designed for investigating sensitive behaviours, to estimate the proportion of farmers in north-eastern South Africa killing carnivores, and use a modified logistic regression model to explore relationships between our best estimates of true behaviour (from RRT) and our proposed non-sensitive indicators (including farmers' attitudes, and estimates of peer-behaviour). Farmers' attitudes towards carnivores, question sensitivity and estimates of peers' behaviour, predict the likelihood of farmers killing carnivores. Attitude and estimates of peer-behaviour are useful indicators of involvement in illicit behaviours and may be used to identify groups of people to engage in interventions aimed at changing behaviour.

“…The Sumatran tiger is exposed to numerous threats which, combined with its low population numbers, has resulted in its classification as critically endangered on the IUCN red list (Cat Specialist Group 1996). The major threats to its survival are habitat destruction, excessive poaching for illegal trade (Nowell andJackson 1996, Morell 2007), prey depletion, and persecution by humans because of the threat to livestock (Linkie et al 2003, Nyhus and Tilson 2004. Linkie et al (2006) studied the occurrence and population viability of the tigers in the Kerinci Seblat National Park, Sumatra.…”

Abstract. Money is often a limiting factor in conservation, and attempting to conserve endangered species can be costly. Consequently, a framework for optimizing fiscally constrained conservation decisions for a single species is needed. In this paper we find the optimal budget allocation among isolated subpopulations of a threatened species to minimize local extinction probability. We solve the problem using stochastic dynamic programming, derive a useful and simple alternative guideline for allocating funds, and test its performance using forward simulation. The model considers subpopulations that persist in habitat patches of differing quality, which in our model is reflected in different relationships between money invested and extinction risk. We discover that, in most cases, subpopulations that are less efficient to manage should receive more money than those that are more efficient to manage, due to higher investment needed to reduce extinction risk. Our simple investment guideline performs almost as well as the exact optimal strategy. We illustrate our approach with a case study of the management of the Sumatran tiger, Panthera tigris sumatrae, in Kerinci Seblat National Park (KSNP), Indonesia. We find that different budgets should be allocated to the separate tiger subpopulations in KSNP. The subpopulation that is not at risk of extinction does not require any management investment. Based on the combination of risks of extinction and habitat quality, the optimal allocation for these particular tiger subpopulations is an unusual case: subpopulations that occur in higher-quality habitat (more efficient to manage) should receive more funds than the remaining subpopulation that is in lower-quality habitat. Because the yearly budget allocated to the KSNP for tiger conservation is small, to guarantee the persistence of all the subpopulations that are currently under threat we need to prioritize those that are easier to save. When allocating resources among subpopulations of a threatened species, the combined effects of differences in habitat quality, cost of action, and current subpopulation probability of extinction need to be integrated. We provide a useful guideline for allocating resources among isolated subpopulations of any threatened species.

“…However, species with large home ranges or migratory habits present broader challenges, because their habitat requirements often extend beyond the boundaries of protected areas (Lambeck, 1997;Caro and O'Doherty, 1999;Sanderson et al, 2001). Principal threats to tigers both within and beyond protected areas include direct hunting but also declines in their prey, exacerbated by habitat loss associated with agricultural, urban and infrastructure expansion, and extractive resource consumption such as logging and mining (Linkie et al, 2003;O'Brien et al, 2003;Dinerstein et al, 2007).…”

Conflict between people and ecosystem capacity is a global problem, and achievement of wildlife-human co-existence a strategic global need. Apex predators suffer disproportionately, including conflicts with human activities. Recovery of formerly declining predator populations, particularly India's Bengal tiger (Panthera tigris tigris), increases potential human conflict. Habitat conversion for arable production and proliferation of non-native tree species increases likelihood of conflict between wildlife, people and stock in villages in the Amlidha buffer zone between core areas of the Ranthambhore Tiger Reserve. Arresting and reversing landscape conversion in targeted zones can reduce potential wildlife-human conflict by regenerating ecosystem capacity, enabling coexistence of a 'green corridor' for terrestrial wildlife migration, a 'blue corridor' for movement of riverine wildlife, and sustainable human livelihoods. This can be achieved through informed and consensual community-based zoning of land uses, management of non-native species and regeneration of local water resources. Conversely, continuing habitat simplification will decrease ecosystem vitality and services, increasing wildlife-human conflict and insecurities. Transition to multifunctional ecosystem management doesn't require wholesale change; elective, consensual adjustments can enhance socio-ecological security. Initiatives by the NGO Tiger Watch involving village people, whose willing engagement is essential for sustainable management, support potential achievement simultaneous wildlife conservation and human benefits.
