Peatland restoration; RSPB The Oa, Isla, Autumn 2023

Tender description

Tender For The Supply Of Peatland Restoration Works On The Oa, Islay Our site is comprised of extensive areas of actively eroding peat hags, gullies, man-made drains and former peat cuttings. The site boundary for the restoration area is approximately 80 ha in size, with the footprint of restoration work to be expected to be approximately 105.36ha. It is expected that the Contractor will work to restore all erosion features in this area using a combination of machine work and hand labour. The work will be procured on a treatment basis which includes machine days, hand labour days and the supply of materials. A range of techniques will be employed to treat the features in this area, these are detailed below within the tender specification. It is anticipated that machine work will be the preference, although there are areas that require hand work for the instillation dams. Required materials will be moved into the area with a suitable ATV such as an Argo, Marooker, Softtrack or Hagglund. We have chosen a variety of restoration techniques that are suitable for this site and some innovation may be required in some areas due to access issues and severity of erosion.
