Light conservation work is carried out which includes wildflower management, coppicing and tree planting. The Cemetery, having been open since 1873, was closed for burials by an Act of Parliament after having been open for more than a hundred years. There are many clerics buried here, including the Bishop of Borneo, and there are four graves tended by the War Graves Commission.

Designated a Sussex Site of Nature Conservation Importance, the graveyard is an oasis for wildlife in the Town Centre. An abundance of grasses and herbs more usually associated with unimproved old meadows can be seen during the summer. A complete botanical survey is carried out through the summer months, and visits are made to record bird and invertebrate species.
