Project summary

Edit project overview to modify the project summary.


Ladywell Fields has been transformed from its previously characterless and formless landscape into a diverse, popular and accessible public open space, with surveys indicating that the public’s perception of the park in terms of recreational value and safety has improved. Now 78% visitors feel safe, and use of the park has increased over 2 and a half times. The creation of a new gravel-bedded river channel through the centre of the park has also brought about significant improvements in biodiversity, with survey results indicating a near 100% increase in the number of species present in the park (in particular fishing birds), which are benefiting from the greater range of habitat types now present following the restoration works.
