Bowden Pillars - Frequently Asked Questions

The Wildlife Trusts support nature-based solutions that deliver genuinely additional and permanent benefits for climate and nature, and do not undermine wider environmental and social integrity.

We do not support schemes that enable mitigation avoidance or that divert pressure and resource away from cutting emissions at source. Any carbon credit scheme must also demonstrate a high standard of transparency and scientific rigour about how it measures carbon and clear evidence of how carbon benefits would not have occurred otherwise. The Wildlife Trusts believe that this evidence is demonstrated in the partnership with Aviva and have written a blog about this new approach to nature-based solutions.

Aviva is publicly committed to being Net Zero by 2040, including emissions from its wider supply chain (known as scope 3 emissions). It has a clear plan to achieve this, with immediate actions and targets for 2025, 2030 and 2040. It is signed up to the Science Based Targets initiative so its carbon-reduction work can be validated and is also using its investment funds and business influence to introduce other companies to Science Based Targets.

Between 2010 and 2021, Aviva cut its own operational greenhouse gas emissions (known as its scope 1 and 2 emissions) by 66%. This publicly disclosed, demonstrable and sustained reduction in absolute emissions is a key consideration for us.

Aviva will only use carbon credits to offset residual emissions that are expected to remain beyond 2040, once all realistic measures have been taken to minimise them.

Aviva’s investment to generate the carbon credits necessary to hit Net Zero is happening now, 15-20 years ahead of any of the emissions that they will be offsetting. Their investment in woodland creation (for instance) will lead to substantial greenhouse gas sequestration well ahead of 2040, even taking account of the time it takes for trees to grow. This means Aviva will not be struggling retrospectively (and potentially unsuccessfully) to recapture carbon that they have already put into the air.

We have taken future climate change into account in the design of the scheme. We are planting a diverse mix of native broadleaf species which are more resilient to fire risk than conifers. The Atlantic rainforest climate zone is also one of the wettest areas of the country, so by its nature this programme should have more in-built resilience compared to other drier and hotter parts of the UK. We do expect some tree losses from natural hazards as would happen in any scheme, and this is built into our carbon sequestration calculations.

Adaptation requirements are a core part of the contract we have with Aviva and we will also be measuring the impacts of our planted trees on local climatic conditions such as temperature and flood risk as part of the project.

Devon Wildlife Trust (DWT) is part of the local communities that we serve and we will work alongside them to determine the most suitable sites for expanding temperate rainforest habitat. This includes ensuring local people benefit from the many opportunities provided by rainforest restoration – through economic benefits, recreation and more.

We have a long history of working in partnership with communities and farmers, and this is vital to achieve the pace and scale that we need for nature’s recovery. Local collaboration is the only way that we’ll combat the crises that threaten us all. 

Restoring wild places, habitats and wildlife is critical for tackling climate change and guaranteeing food security. The UK Food Security 2021 report identified climate change and biodiversity loss as the biggest threats to food production in future. Reviving and expanding UK rainforests will help address these twin emergencies.

The new rainforest is part of a wider project, called Bowden Pillars Future, which has the ambition to transform the area into a beacon for sustainable development and regenerative agriculture. This will grow food for the local community and include agroforestry, grains for the local mill, a grass-fed cattle herd, a market garden and new orchards.

The trees planted will be a mix of deciduous, native species sourced from seed collected in England. We will aim to source the seeds as local as possible, and this will include those grown by Woodland Trust and DWT’s Saving Devon’s Treescapes tree nurseries based in the county.

Approximately two thirds of the land managed by Devon Wildlife Trust (circa 52 acres) will be turned into woodland, and the remaining third (circa 23 acres) will be turned into other habitats. Of the woodland, 50% will be planted and 50% will be allowed to regenerate naturally.

Tree species will include sessile oak, birch, rowan, holly, alder, willow and hazel. They are home to stoats and pine martens, and threatened birds like wood warblers, redstarts, and pied flycatchers. Wet conditions found in a rainforest support an abundance of mosses, liverworts, lichens, and ferns – many of which grow on the trees or cover boulders and ravines. The dampness is ideal for fungi, including globally rare species like hazel gloves fungus.

A deer-proof fence will be installed on the external boundary of land managed by Devon Wildlife Trust. Individual trees will not be protected unless there is an issue with rabbit grazing – in this case we would protect the trees with short spiral guards.

A rainforest is a type of damp woodland. You will know if you are in a rainforest because you will be surrounded by a wonderful abundance of mosses, liverworts, lichens, and ferns – many of which grow on the tree branches and trunks and cover boulders and ravines. The dampness of the air will be ideal for fungi to grow, including globally rare species such as hazel gloves fungus. Woodlands tend to be less damp with a less dense undergrowth.

Totnes is within Britain's 'oceanic zone', and the steeply sided slope of the land tumbling down to the river below creates the ideal conditions for a rainforest to grow. Although we do not know how our environment will change in 100 years, larger areas of woodland canopy will be better able to support the conditions of high humidity needed for rainforests and will help buffer against temperature extremes.

Native to the British Isles, temperate rainforest is an incredibly rare and wildlife rich habitat that once stretched from Cornwall to the west of Scotland. Now it covers less than 1% of the UK, in areas such as western Scotland, the Lake District, western Wales and here in the South West. It is much rarer than tropical rainforests. The Atlantic Rainforest Restoration Programme is the first attempt to go beyond restoration of remaining fragments to establish new woodlands that will begin a reconnection of the Atlantic rainforest. We aim to create bigger areas of rainforest that are better managed and more connected – the start of a 100-year journey to recreate the lost rainforest of the British Isles and Northern Ireland.

Native to the British Isles, temperate rainforest is an incredibly rare and wildlife rich habitat that once stretched from Cornwall to the west of Scotland. Now it covers less than 1% of the UK, in areas such as western Scotland, the Lake District, western Wales and here in the South West. For this rare and precious habitat to survive we need to create new woodlands to reconnect these fragments of rainforest so that bigger areas of rainforest can start to thrive and regenerate, without this intervention UK rainforests will remain just fragments and will never achieve their full potential.

A mix of planting and natural regeneration will be important in restoring rainforests. Natural regeneration is the safest way to ensure natural woodland develops, however it is made up of trees which exist in the local area. Planting trees enables us to improve tree diversity, which makes a habitat more resilient to pressures like disease, and bring back species in the area which have recently been lost.
