Project summary

Edit project overview to modify the project summary.

Develop a better entrance way into the park linked to the River Shuttle walk, including new bridge over the river itself
Enhance river marginal plant diversity
Improve the woodland management
Provide new play equipment for children
Wetland creation The River Shuttle runs in a straightened channel through Parish Wood Park, a small park on the Bexley/Greenwich border. The river has good form but has a monoculture marginal plant community. A new wetland will provide a new type of habitat for the Shuttle corridor.
