Established forest and growth in Upton Park near Liverpool . Left , from top : Upton Park , with the town of Moreton in the distance ; old growth in the forest ; new trees planted by the Mersey Forest Partnership . 13 million residents , foster biodiversity , and create biocorridors for wildlife like beavers and even wild lynx . The Mersey Forest Partnership works with communities , landowners , and businesses and supports a myriad of projects including forest schools , woodland management , and the creation of green jobs , along with the establishment of forests . It ’ s the work of a diverse coalition of partners and funders , including HP partner the Arbor Day Foundation , that has doubled the region ’ s woodland cover since 1994 . As the Mersey Forest nears three decades in action , some of those earliest efforts have yielded idyllic copses and fully established woodlands , while at other sites saplings are just taking root . Roughly halfway between Liverpool and Manchester , Collier ’ s Moss Common , for example , has been transformed from a once-abandoned area near a power station to a verdant forest that ’ s a favorite of hikers , bikers , and horseback riders . A short drive away , mature trees sway high above Sudley Fields on the outskirts of Liverpool , where local volunteers recently planted 50 delicate saplings to bolster the tree cover . “ The Mersey Forest and the wider Community Forest network represent one of the largest ecological regeneration initiatives in England ,” says Abbie Eisenhart , director of corporate partnerships at the Arbor Day Foundation . “ Thanks to the support from HP , we ’ re able to elevate our work and help these communities benefit from direct access to green spaces and trees , which aid flood mitigation , enhance air quality , and improve physical and mental well-being .” — Elizabeth Sheldon HP / INNOVATION / SUMMER 2023 61
