"The campaign is extremely important as it will buy and restore Horse Common to its former glory.
"This will bring back bird species that have been pushed out including providing homes to endangered species such as nightjar and spotted flycatcher.
"Both are rare in the UK due to a lack of sustainable habitat and suitable food. Restoring habitat brings back a large range of biodiversity, and restores the natural cycle within the forest."
The campaigner added: "Nature and being outdoors is so important for positive mental health, especially during lockdown, and is helping millions."
