As Dutch elm disease spread across Britain in the 1970s, the country fell into mourning. When the sentinel trees that framed our horizons were felled, their loss was a constant topic of sad and angry conversation. Today, just a few years into the equally devastating ash dieback epidemic, and as the first great trees are toppled, most of us appear to have forgotten all about it. I’ve travelled around much of Britain this summer, and seen the disease almost everywhere. A survey published this spring found infected trees across roughly three-quarters of England and Wales: the spread has been as rapid and devastating as ecologists predicted. But in this age of hypernormalisation, only a few people still seem to care. Ash to ashes: our memories wither as quickly as the trees.
And almost nothing has been learned. Our disease prevention rules, whose scope is restricted by the European Union and the World Trade Organization, and whose enforcement is restricted by the British government’s austerity, do little to prevent similar plagues afflicting our remaining trees. Several deadly pathogens are marching across Europe. While it is hard to prevent some of these plagues from spreading across land, there is a simple measure that would stop most of them from spreading across water: a ban on the import of all live plants except those grown from tissue cultures, in sterile conditions.Continue reading...
