Biodiversity Records

Here you can download some of the available information about the biodiversity of the Steyning Downland Scheme.

We are always looking for more biodiversity records to help us build up a picture of the ecology of the downland. Do please send us your records – thank you.

The Steyning Downland includes two Sites of Nature Conservation Importance (SNCIs), which are non-statutory nature conservation designations made by West Sussex County Council. You can download more information about our SNCIs here.

For an overview of the natural history survey information available up to 2011, please read the A Rocha summary report here.

Two surveys of the Steyning Downland Scheme have been carried out by the expert botanists of the Sussex Botanical recording Society (SBRS). They have recorded 143 plant species in total. You can read SBRS chairman Nick Sturt’s report here.

Butterflies

View summary information for the butterfly transect data collected by the Dukes of Steyning Project, supported by the Heritage Lottery Fund. Three transect routes were planned for us by butterfly expert, Neil Hulme and then walked regularly by 16 butterfly monitors who volunteered from the local community. You can download the maps for these below:
