The most frustrating topic surrounding wild boar is when people, which we've see lots of examples from wildlife photographers to those who believe they are doing good, feed wild boar.
Not only will it increase the chance of them contracting, and spreading, disease such as African swine fever (ASF), feeding wild boar will habituate them and can cause them to lose their natural fear of humans. In turn this could cause conflict with people who do not want the wild boar approaching them. This activity will also make the wild boar easy targets for those who want to do them harm.
If you are comfortable and confident being around the wild boar, just stand and admire them, they are very capable of finding their own diet.
As with all wildlife, treat with respect and remember you are in their home when you are out walking.
By following these guidelines, you will hopefully have a wonderful experience.
