| Achoimre: | Hedgerow surveys were undertaken in April and May 2015 across the Ditchley Estate. Hedgerows were identified via satellite imagery, and on-site visits were used to confirm the presence of a hedgerow.
A total of 145 hedgerows were surveyed according to the methods described in the "Hedgerow Survey Handbook" (Defra, 2007). All data was recorded in line with the survey methods described in this handbook.
Hedgerow_ID: The Hedgerow_ID was based on consecutive number for each hedgerow identified via satellite imagery. If a hedgerow was longer than 100 m, it was split into sections of equal length, with each section assigned a letter (A, B, C etc.). Hedgerow_IDs are unique.
Margin width: Where hedgerows were adjacent to grassland, and so there were no clearly marked field margins, the margin width was recorded as "grassland".
GPS coordinates were recorded using a handheld GPS.
Data has been checked and any missing values noted as NA.
