The zone has become a de facto wildlife sanctuary because hunting is forbidden. That is to protect people from radioactive game. There are no services to protect the wildlife. But agenecies such as Chernobyllis, which means "Chernobyl Forests" is charged with managing the woodlands. Even though that isn't their official job, they are also best informed about the animals -- including the Przewalski's horses. This Chernobyllis rep has dragged the head of a poached filly from the basement into the cold winter light.
If the zone is declared an official nature sanctuary, all the wildlife -- including the Przewalski's horses -- will have more robust protection. This is something I will be calling for at various Chernobyl conferences that will be held on the 20th anniversary on April 26th.
