The first challenge is to identify that it's here. We need the science to identify that a pest is present. We then have the ability to set up quarantine zones to prevent the spread. In some cases, wood, firewood, can be a host for plant pests. We have the ability to restrict movement through ministerial orders. We try to contain. Sometimes it means we have to cut down trees. We try to set up a buffer zone to prevent spread from an area.
