GFF-0454 Moccas Park has now been expanded and has been joined by Gillian’s Wood. The new name is “Moccas Park and Gillian’s Wood NNR”.
The Moccas Park section is accessible by permit only but this is irrelevant now as the Gillian’s Wood section is open to the public.
Using the Defra map you can see which area is “Moccas Park” by using the SSSI filter which highlights Moccas Park as it is also and SSSI which Gillian’s Wood is not.
