Strategy puts Wirral Council on course for 210,000 new trees by 2030

How is this tackling the climate crisis?

The ability of trees to capture and store carbon means they have an effective role in combating the climate crisis, alongside emissions cuts. Tree planting is also popular right across society – so is a great way to get communities and council partners on board with climate action.

In recognition of this, Wirral Council has created a detailed and ambitious ten-year strategy to safeguard local trees and plant hundreds of thousands more, on and beyond council-owned land

The Wirral Tree, Hedgerow and Woodland Strategy 2020-2030 was developed in collaboration with an impressive network of partners including tree wardens, community groups, private, charitable and community landowners, and local and national tree organisations. It has three elements: participate, protect and plant.

Participate relates to encouraging the kind of robust community support that will be vital for the success of the strategy. Protect recognises that planting new trees is not enough; a sapling does not deliver the same environmental benefits as a fully matured 300-year-old oak. Therefore, existing trees must be cared for, because retention is preferable to planting.

Finally, to complement the safeguarding of existing trees, the authority will plant 21,000 new trees every year for the next decade. Planting will be guided by the principle of ‘the right tree for the right place’. Correctly sourcing, planting, and maintaining trees will enable the Wirral to nurture a diverse and resilient stock of trees of varying age and species. The 210,000 new trees will increase Wirral’s canopy cover from 13% to 25%.

The council began consulting on the strategy in late 2019. It officially came into force in August 2020 and planting begun in January 2021, the earliest planting season after the strategy’s enactment.

The council is taking its approach extremely seriously, with the tree strategy reviewed annually by the council and its stakeholders. A cross-disciplinary working group will also track the effectiveness of the strategy over time. The council hopes that this first decade will be the strong foundation for a vision spanning the next 50 years and beyond.

What impact has it had?

Ahead of target

By September 2021, 24,032 trees had been planted across the Wirral, putting the council well ahead of its annual target of 21,000 trees, despite the complications of coronavirus. The pandemic limited community planting, but this problem was offset by other developments – contractors were able to carry out early planting, as were schools (which were subject to different social distancing guidelines). Of the trees planted so far, 700 arrived through the Urban Tree Challenge, 10,000 via the Eco Schools programme involving 32 schools, and a further 10,000 were planted in two new woodlands in conjunction with Mersey Forest contractors.

Forging community links

The tree strategy has also prompted the creation of the Wirral Initiative on Trees, which brings together some of the council’s key partners. These include, but are not limited to: Wirral Tree Wardens, the Friends of Wirral Parks Forum, Wirral Environment Network, The Wirral Society, Wirral Wildlife, the Urban Beekeepers Association, and Wirral Countryside Volunteers. The Wirral Initiative on Trees is an indispensable forum for sharing information about the tree strategy with communities, and also gathering their feedback.

Projected carbon impacts

It is projected that by 2030 the Wirral Tree Strategy will have led to the sequestration of 222 tonnes of carbon. In 2022, a study by forestry organisation Forest Research will examine the strategy’s impact in its first few years.

What made it work?

Partnership Working

The strategy involves a huge amount of collaboration. The council was keen to make use of external expertise and input from specialists. As well as insights from the groups that joined the Wirral Initiative on Trees and public input obtained via consultation, support came from partners including the Tree Council, Forestry England, Natural England, Urban Trees and the Woodland Trust. Drawing on a wide range of existing knowledge on trees allowed the council to implement its project without starting from scratch.

Political Co-operation and Commitment

The strategy passed with fervent all-party support on a council with No Overall Control. The council also benefitted from the enthusiasm of one councillor as a key champion of the strategy.


Expanding tree cover is people intensive, but in Wirral much of the tree-planting will be carried out by a cohort of volunteers offering their time. Wirral Council also made use of free online tools such as i-tree, a platform which estimates tree canopy cover and can measure the structure and composition of trees.

Multiple Co-Benefits

Trees provide a host of social, health and economic benefits on top of their positive environmental impacts. Trees can help reduce noise, create a feeling of safety within communities, and generate a sense of place, identity and pride in local areas. Trees also improve air quality, boost mental health, and create more attractive environments for outdoor exercise. Economically, the aesthetic value of trees can increase property values, boost tourism and recreation revenue, and improve the productivity of employees.

Accessibility and community engagement

There is no financial barrier to volunteer-based tree-planting so it is an activity that, ability permitting, most people can participate in. The council will host community planting events where it will supply necessary equipment like spades and mulch. The council intends to publish volunteer’s stories on social media to demonstrate the diversity of people taking part and gain buy-in from a variety of demographics.

With dozens of locations earmarked for new trees across the Wirral, residents should be within reach of at least one tree-planting opportunity. If not, the council accepts suggestions for new locations directly from residents. Tree-planting initiatives are easy for people to understand (unlike some other climate interventions), therefore easy to promote and secure involvement. Community engagement, connection and cohesion are further co-benefits that flow from the accessibility of tree-planting.

Previous Work on Trees

Between 2018 and 2020 the council had already successfully worked with schools, children and families to plant over 15,000 trees.

What resources were needed?

Writing the strategy did not create any external costs. It which was produced by a team of four to five people at the council with regular editing and input by stakeholders over roughly 12 months.

The council is using a variety of streams to fund the tree strategy. These include the UK Government’s Urban Tree Challenge Fund, Mersey Forest’s Trees for Climate budget, and the council’s own dedicated climate emergency revenue budget. It also intends to apply to the council’s capital finance programme. In 2020, the council was successful in obtaining £249,630 from the Urban Tree Challenge fund and agreed to match this funding, amounting to a total £600,000 for new trees in 50 locations across the borough. A further £23,743 grant was received from Mersey Forest, which covered all costs for two woodlands comprising 9,306 trees.

English local authorities can also access the government’s England Woodland Creation Offer – grants to support the creation of new woodland launched in June 2021.

To carry out the strategy the council has established several additional posts to bring new in-house expertise on board. These include a new role of Landscape Manager for the Tree Strategy, working alongside a tree risk manager and four tree inspectors.

Lessons learned

Include protection for existing trees

It is important that tree strategies included protection of existing trees, and restoration of existing woodland, wherever possible to ensure maximum impact on climate and biodiversity. The council also found that this was essential to gain public support.

At the public consultation stage, Wirral Council received many positive responses to the proposed strategy, but also encountered emphatic opposition to felling trees under any circumstances. There was some scepticism about the plans, because the council had felled 2,225 trees in the years leading up to 2020. As a result of this strong feeling, the strategy now clearly states that felling is always a last resort. Other councils should anticipate a strong reaction to any past or current felling of trees, and be prepared to respond to concerns. In the Wirral, once planting got underway trust was built through visible action, allaying public anxieties.

The right tree in the right place

The replicability of the Wirral approach to increasing tree coverage will depend on local geography. Strategies should be tailored to the local landscape and ecosystems, though some principles such as ‘the right tree in the right place’ are universally applicable. Wirral was already home to eight Sites of Special Scientific Interest (SSSIs) which the council owns parts or all of, plus existing woodlands at Dibbinsdale, the Dungeon, the Beacons, and Eastham Country Park. Other parts of the UK will differ to the Wirral in degree of urbanisation relative to forested area or may include valuable habitats where tree-planting is inappropriate (for example, grasslands, marshlands, sand dunes, etc).

Work across boundaries

Trees, forests and woodlands cross political boundaries. Councils may need to work with neighbouring councils or encourage neighbours to implement their own measures to protect trees and increase tree cover. Trees are a relatively apolitical subject, as evidenced by the agreement between parties on Wirral Council – this should facilitate cross-boundary, cross-party partnership.

Importance of good data

An extremely important lesson for councils looking to expand their own tree coverage is the need for good data. In Wirral, the council has created a comprehensive database which catalogues all of Wirral’s existing trees. Each new tree planted is entered into the system and given a unique reference number. Using tools like i-tree enabled the council to map trees, their condition and their ecosystem value. This made it easier to identify gaps with which to fill new trees, or those locations where new species needed to be introduced to increase resilience. Good quality, up-to-date data on trees is crucial.

A long-term commitment

A further lesson is that tree-planting is not a ‘quick-win’. To deliver their full benefits, trees need to be nurtured into maturity. Councils must know that this is a long-term commitment, because many tree-planting schemes fail due to poor follow-up care. The pay-off on indicators like air quality may not be immediate.

Good communication is vital

Finally, councils need to develop a strong communication strategy and education campaigns otherwise they will not secure the volunteers needed to plant significant numbers of trees. Keeping local people on board and giving them ownership is the lifeblood of the Wirral’s Tree Strategy. Education is important to teach communities and residents how best to take care of the trees they plant and, indeed, to get them to care about trees in the first place. Councils with an existing pool of climate champions have manpower ready to mobilise for tree-planting.

Wirral View, the council’s news outlet, publishes a bi-monthly newsletter dedicated to local stories on the environment and climate change.
