Since discovering the first large scale infection of ash dieback on the MOD’s Defence Training Estate (DTE), Landmarc Support Services (Landmarc) has worked with the Defence Infrastructure Organisation (DIO) on a rigorous programme to help combat the disease.Īfter subsequent survey work, the infection was identified in many of the woodlands across the DTE, in various degrees of severity. Over two-thirds of the Ministry of Defence (MOD)’s land is held solely for training the armed forces, but it is also well used by the general public, farming and hobbyist tenants.
