I am wondering what kind of methods people use – in practice – to set boundaries to indicate where wild boars are allowed and where not. For instance, a gate is an obvious tool, but what kind of methods are used and might be successful or temporary successful to delineate spaces where boars are allowed/not allowed. These tools might be targeting people as well as the wild boars (e.g. think about roads where wild boars are deterred by e.g. mirrors and/or humans are targeted to reduce speed by speed bumps to be able to brake in time). Please share any practical tools/methods you are aware of or even have experience with.
