Trees provide many goods and services which we rely on, so it’s important that everyone plays their part in protecting the health of our trees. Everyone can do this, whether a forester, an arborist, an Observatree volunteer or a woodland visitor. The main way in which people can help protect our trees is to reduce the movement of potentially infected material from site to site, as pests and diseases can be found in soil, organic material (leaves, timber, woodchip and firewood) and water. Just by simply cleaning boots, bikes, tools etc between sites we can reduce the risk of moving potentially infected material around with us and introducing it to new sites.
