Restoration of PAWS is an important procedure for the overall improvement of woodland biodiversity and is currently of great interest to woodland managers.
PAWS are sites that have a long history of woodland cover: they are ancient semi-natural woodlands on which the original, “natural” woodland was cleared, and replaced by a plantation of either native or exotic species.
There are several factors driving the restoration of plantations on ancient woodland sites. These include:
The aim of PAWS restoration is to retain remnant features of ancient semi-natural woodlands and restore the site to woodland comprising site native species. This will not be easy on some sites and the current programme of research is investigating the changes that occur on site following different silvicultural treatments:
Conifers were established on many ancient semi-natural woodlands between 1950 and 1980: for most people these probably typify PAWS. Plantations of several species of exotic conifers were established on a variety of site types and currently research is concentrating on woodlands where Corsican pine (Pinus nigra ssp. laricio) was established on clay soils.
Native species comprise approximately 30 to 40% of PAWS and those planted with beech (Fagus silvatica), which casts a dense shade, can have a severe effect on the growth of other native trees, shrubs and herbs that would normally grow on the site. An experiment is investigating how to introduce more diversity into these beech plantations.
