Boundary Types

Introductory Note

The definitions of the various types of boundaries are not absolutely precise. It is easy to say that a hedge is "intact and species rich" when it is obviously extremely healthy, thick and containing 6 or 7 different species. However, it is very difficult to be precise about exactly at which point it becomes "species poor", or where it becomes "defunct". We have used our judgement to the best of our ability and would welcome input or corrections from anyone.

1. Intact species-rich hedge. Hedge looks in pretty good health, in particular, is more-or-less unbroken, and would form a barrier to cattle for most of its length. Has at least three different species making up the hedge.

2. Intact species-poor hedge. Hedge looks in pretty good health, in particular, is more-or-less unbroken, and would form a barrier to cattle (for almost all of its length). Has only one or two different species making up the hedge.

3. Defunct species-rich hedge. Hedge has deteriorated and has several significant gaps in it, and would not form a barrier to cattle. Has at least three different species making up the hedge.

4. Defunct species-rich hedge supplemented by wire fence. Hedge has deteriorated and has several significant gaps in it, and would not form a barrier to cattle by itself, but has wire fence covering the gaps. Would form a barrier to cattle in the combined state. Has at least three different species making up the hedge.

5. Defunct species-poor hedge. Hedge has deteriorated and has several significant gaps in it, and would not form a barrier to cattle. Has only one or two different species making up the hedge.

6. Defunct species-poor hedge supplemented by wire fence. Hedge has deteriorated and has several significant gaps in it, and would not form a barrier to cattle by itself, but has wire fence covering the gaps. Would form a barrier to cattle in the combined state. Has only one or two different species making up the hedge.

7. Intact Fence. Boundary made of wood or wire, more-or-less continuous and would form an effective barrier to cattle for most of its length. May have brambles and similar plants on the fence, which may even form an effective barrier, but the brambles are disregarded for the purposes of this map.

8. Defunct Fence. Boundary made of wood or wire, which has several significant gaps in it and would not form an effective barrier to cattle. May have brambles and similar plants on the fence, which may even form an effective barrier, but the brambles are disregarded for the purposes of this map
