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

Notes
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.
