Slowing Pine Weevil progress

Natural Resources Wales has embarked on an environmentally friendly programme to tackle a pest that lives on conifers: the pine weevil.  NRW is to spray microscopic Nematode worms into and around conifer tree stumps to combat the pine weevil.  The work starts in the Tywi Forest, near Llandovery in Powys before moving northwards to the Hafren Forest, and finishing in Clocaenog Forest in Denbighshire.  The total area covered will be nearly 500 acres (~ 276 football pitches).

Neil Muir, Forest Manager for NRW said:

“Pine weevils can have a devastating impact on young trees. We are trying to move increasingly towards using this biological control method to combat them and create more resilient forests. The nematodes eat the weevil grubs tackling the problem at source. Reducing the overall population of weevils in the forest block which will reduce the damage to young trees and create a more resilient forest. We will monitor the work closely to see if the method can be applied even wider in future, cutting down further on the use of chemicals.”
