  • Land LimitationsPoor Agricultural Land (blanket bogs, gley soils)Pinus spp proved to be the best performer on these soilsThe performance of broadleaved species was unsatisfactory at most sitesBetula survived at many locations but gave an unenonomic yield

  • Trials on Harvested PeatlandReasonable yields only obtained where there was at least 0.5m of peat remaining. Very poor yields obtained when plants were sown directly into calcareous marlSalix and Populus proved to be the most promising species generally although there was considerable variation among species.
