Making use of harvest information to examine alternative management scenarios: a body weight-structured model for wild boar

摘要: Summary 1. Harvest models are often built to explore the sustainability of dynamics exploited populations and help evaluate hunting management scenarios. Age-structured commonly used for ungulate population dynamics. However, age hunted individuals is usually not recorded, data only include body weight sex limiting usefulness traditional models. 2. We propose a new modelling approach that fits collected by hunters develop rules when available. Using wild boar Sus scrofa as case study, we matrix model structured according whose output can be directly compared with observed distribution among classes. 3. In face current wide scale increase in boar, best feasible option stop or slow down growth involves targeting effort specific classes. The optimal harvest proportion target classes estimated using sensitivity analyses. 4. The number shot each class predicted our was closely associated those recorded bag. Increasing pressure on medium-sized females 14·6% limit rate 0·90. 5. Synthesis applications. We demonstrate could reliably control growth. Our applied any game species where group composition, phenotypic traits coat colour allows easily identify This offers promising tool applying selective species.
