Brown hyaena population explosion: rapid population growth in a small, fenced system

摘要: Context In the past 200 years, many carnivores have experienced a widespread decline in numbers and range reductions. Conservation interventions include use of small, fenced reserves that potential restoration benefits for conservation. Over 25 Eastern Cape province South Africa has seen establishment small (≤440 km2) game reserves, reintroduction larger, indigenous wildlife had been extirpated by early 20th century, including brown hyaenas (Hyaena brunnea). These restored environment to more natural state but little information exists concerning implications introducing elusive animals are seldom after reintroduction. Fenced provide surplus can be relocated purposes (where applicable) or serve as buffer extinction naturally occurring populations, careful management is required monitor populations appropriately, so avoid costs rapid population increase. Aims The provided case study assess role their contribute conservation, determining persistence growth enclosed reserve. Methods Estimates hyaena density were calculated using capture–recapture approach from individually identifiable images captured during 3-month camera trapping survey. Key results After single decade, increased at least 367%, six individuals minimum 28 individuals. suggest this highest ever recorded species southern Africa. Conclusions Implications Because high relative unfenced fences may two utilities support reintroductions protected risk extinction.
