THE HEDGE (& WALL) IMPORTANCE TEST

The Hedge (& Wall) Importance Test (HIT) was devised by Robin Menneer FRICS MSc in response to the need for a simple, economical, accurate, safe and non-invasive method of surveying and assessing hedges, hedgerows, hedgebanks and walls on a national basis. Its innovative scoring concept provides data compatible with the Hedgerows Regulations criteria and covers every type of hedge or wall while also taking into account regional, county and local distinctiveness. The HIT is available free online and is easy to use by the general public. It was originally placed with the Cornwall Wildlife Trust's Environmental Records Centre for Cornwall and the Isles of Scilly (ERCCIS) and accessed via the Cornish Hedges Library website at www.cornishhedges.co.uk

We are sorry to have been told that ERCISS is not at present able to maintain the full online HIT facility. This automatic service can only currently be accessed on the internal computer system by visiting the Cornwall Wildlife Trust at Allet, Truro.

Therefore we give here the do-it-yourself scoring system to download and print out along with the HIT survey form.

The only part of the HIT not currently widely available is the automatic print-out giving full description of the hedge or wall, constituting an un-biassed assessment on paper of the importance of the hedge or wall which is invaluable in, for example, cases where protection is desirable during development schemes etc. Until this service can be reinstated, the points sheets and results for the hedge, which include the following information regarding the meaning of the HIT mark, can be presented for these purposes.

Typically hedges score from 4 to 7 marks (out of ten), indicating a fair to very good hedge which is capable of improvement in landscape and wildlife terms by suitable management. Often a hedge may score a higher individual mark for landscape, wildlife or history than its overall HIT mark, so it is always advisable to work out these individual marks. A hedge scoring below 4 marks in all three is less important but will usually be capable of improvement, perhaps in time by at least two overall HIT marks, eg by establishing nearby habitat, planting in extra species and allowing trees to grow up.

Any hedge or wall scoring 8 or more marks overall, or 8 or more for any of its three individual marks, is precious and should be accorded a sensitive grade of care and preservation. Given the information entered, a hedge with this mark or above may qualify for protection under the Hedgerows Regulations 1997. The mark 10* (ten star) indicates a highly outstanding hedge which has scored above the number of points required for overall or individual HIT mark 10. A hedge or wall scoring lower than this may score HIT Mark 10* for any of its three individual scores for landscape, wildlife or history.

The hedge or wall record, score and HIT mark rely solely on the factual information entered on the HIT survey form and are not subject to the surveyor's opinion or specialised knowledge. The easily-recognised plants entered on the HIT form are indicator species. They do not represent a full species count, but indicate the type and health of the hedge and pinpoint those hedges that may be worth a full species survey.

Scoring the hedge for the three individual HIT marks for landscape, wildlife and history gives a valuable indication of the type of care desirable to maintain its particular special value. Please note, the mean average of the three individual marks may not be the same as the overall HIT mark due to rounding differences.

The survey form and points sheets are designed to print out handily using both sides of A4 paper.
