Trees are infected in the summer by airborne spores from fruit bodies occurring on the central stalks of fallen leaves – moist conditions favour the production of fruit bodies. Current knowledge does not provide clarity on the impact of ash dieback on the life expectancy of individual ash trees, although up to 5% of ash trees will show genetic tolerance to the disease and many trees growing in open sites may not succumb to the disease and are likely to persist indefinitely. You have to assume that the EAB is still in the wood and therefore you should not transport it further than 50 miles from your property.
