Tree officers and those managing the urban forest often have quite a tough time of things. They’re on the front line of arboriculture when the complaints come in, fending off the classic “I love trees, but..” correspondence and patiently explaining that there really is no council conspiracy to remove/retain a healthy/dangerous tree (delete as applicable).
Ceratocystis platani (plane wilt) is a fungal disease affecting plane trees in some parts of the European mainland including France, Italy and Greece. It only affects plane trees, compromising the vascular system and ultimately leading to the death of the infected tree. It spreads via spores, typically transported from one tree to another by infected equipment such as chainsaws. The disease is not known to be present in the UK. In order to minimise the risk of it entering the country the UK has been designated Protected Zone Status (PZS) by the EU, placing restrictions on imports of plane saplings.
