*Estimated carbon sequestration is 20 kg of CO2e per tree accumulated over five years, based on low estimates of dry and humid tropical growth rates from global restoration databases.

Actual carbon impact of each Priceless Planet Coalition restoration project will be assessed after five years based on data collected throughout the monitoring process.

Restoring Scotland’s rainforest

In Scotland, Conservation International is partnering with Argyll and the Isles Coast and Countryside Trust to restore, expand or connect existing pockets of remnant Scottish rainforest habitat found in Argyll. Restoring these types of diverse, long-standing native woodlands can play a key role in tackling the twin biodiversity and climate crisis the planet faces and help to maintain the connection between Argyll’s rainforest and the communities who visit, live and work in it.

Nature of the terrain

Argyll and Bute’s rainforest, known as temperate rainforest, consists of an increasingly rare and threatened habitat of ancient native woodland, open glades, boulders, rocky cliffs and river gorges that form a backdrop for some of the best scenery in Argyll and Bute. The hyper-oceanic climate, gentle slopes, deeply penetrating sea lochs and island network of Argyll and Bute provide perfect growing conditions for the lower or nonvascular plants that define this diverse and unique temperate rainforest habitat.

Restoration methods

Tree planting
The planting of seedlings over an area with little or no forest canopy to meet specific goals.

Assisted natural regeneration
The exclusion of threats (i.e., grazing, fire, invasive plants) that had previously prevented the natural regrowth of a forested area from seeds already present in the soil, or from natural seed dispersal from nearby trees. This does not include any active tree planting.

Tree species

Preliminary list includes:

  • Sessile oak (Quercus petraea)
  • Downy birch (Betula pubescens)
  • Rowan (Sorbus aucuparia)
  • Alder (Alnus glutinosa)
  • Willow (Salix various)
  • Aspen (Populus tremula)
  • Wych elm (Ulmus glabra)
  • Hazel (Corylus avellana)
  • Crab apple (Malus sylvestris)
  • Wild cherry (Prunus avium)
  • Hawthorn (Crataegus monogyna)
  • Blackthorn (Prunus spinosa)
  • Elder (Sambucus nigra)
  • Holly (Ilex aquifolium)
  • Juniper (Juniperus communis)
