Manual control, such as felling and ring-barking, has been the traditional means of killing wilding pines in New Zealand. Now, however, in the forested areas of the Marlborough Sounds, felling is generally only recommended for trees of less than 200mm trunk diameter. The felling of larger trees entails land disturbance and damage to surrounding vegetation during control. A felled tree will break down a lot of native vegetation when it falls, and the 'light well' on the forest floor is generally an ideal site for the germination of pine seed. Very often, dozens of young trees can be found growing up around the site of a felled wilding pine. For this reason, trees above 200mm should be killed standing wherever possible. Ring-barking is also now discouraged, as the method has proven slow and unreliable.
