Where the PwC and Trees for Cities partnership started

What began with a single event — organised by our very own Georgina Logan, who started out as Corporate Partnerships Coordinator before moving across to our Urban Forestry team — has since blossomed into a long-standing partnership. 

Over the years, thousands of PwC employees and interns have given up their time to support our tree planting and maintenance projects, attending large-scale corporate volunteering days, often as part of PwC’s 'One Firm One Day' (OFOD) initiative.

From digging and planting to watering and mulching, we’re deeply grateful to the PwC team for always getting stuck in with hands-on urban greening, with many experiencing their first taste of environmental volunteering.

How PwC volunteers are helping restore Horsenden Hill 

Among the many landscapes transformed by our partnership with PwC, Horsenden Hill in Ealing, north London, stands out as a powerful example of just what can be achieved when organisations unite behind a shared vision for nature. 

Horsenden Hill is Ealing's largest nature conservation site, spanning 100 hectares of woodland, meadows, ponds and wetlands. Together with Ealing Council, local groups and volunteers, we've been helping to restore and enhance this important green space for both people and wildlife. 

PwC volunteers have played a key role, supporting careful site preparation and planting thousands of young trees to create new habitat, boost biodiversity and help to build a greener, more climate-resilient future.

Essential tree maintenance at Horsenden Hill

We know that getting trees in the ground is just the beginning — the real work starts after the spades go down. Ensuring the trees we plant survive and establish requires ongoing care long after planting season has ended. 

At Horsenden Hill's Home Field, PwC volunteers continue to support maintenance work for trees planted in previous winters. Activities like laying mulch may seem simple, but they make a huge difference to the health and survival of young trees. Mulch rings help funnel rainwater towards tree roots, retain moisture, suppress competing vegetation, and enrich the soil, giving newly planted whips (young trees) the best chance to establish.

This kind of hands-on care shows just how important long-term stewardship really is. Every hour volunteered helps support the future of these young urban trees, maximising the environmental benefits they'll provide for years to come.

A landscape for nature recovery 

The work taking place at Horsenden Hill in partnership with PwC forms part of a much bigger story of nature recovery. 

Alongside newly established woodland areas, the wider site is home to habitats that support birds, insects, and mammals. It’s also become known for innovative conservation projects, including the nearby Ealing Beaver Project, a London-first, that’s already showing signs of success. 

Together, and with the help of PwC volunteers, these initiatives are helping create a thriving landscape where people and wildlife can flourish side by side.

Looking ahead and leaving a legacy 

Our partnership with PwC shows what can be achieved when organisations come together with a shared commitment to people and planet. 

From that first event in 2018 to the large-scale volunteering days delivered today, PwC colleagues have contributed their time, energy, and enthusiasm to projects that leave a lasting legacy. Whether planting new woodlands, maintaining young trees, or supporting habitat restoration, every volunteer has played a role in creating greener, healthier urban environments. 

As our partnership continues to grow, we look forward to welcoming more PwC volunteers to sites like Horsenden Hill and beyond, working together to create spaces where communities can connect with nature, and where future generations can enjoy the benefits of a greener city.
