									Restoration Protected
The Trust have protected an historic feature in the Tale Valley near
Clapperentale Farm. “Leat 2” as it is known on archaeological plans is the
main water channel that feeds the Lower Tale water meadow system.
The Trust have repaired some of the
Victorian brick sluice gates and are
investigating nearby springs and land
drains to see if they can fill the leat
system with water without having to
build eight hundred metres of culvert.

Once the Trust have solved the water
delivery system they will be able to start
the next phase of the project to recre-
ate a bedwork water meadow system in
exactly the same way it was built over
two hundred years ago.

The ambition is to hold working dem-
onstrations of this traditional meadow
management system and run the only
working water meadow system in
Devon.

At one time every river valley in the
county had water meadows, which were
“drowned” each winter and spring to
promote grass growth. With the agri-
cultural revolution this practice died out
and the wildlife benefits of this gentle
technique went with it.

These days green monocultures
predominate the Devon landscape,
with prolific grass production fuelled by
inorganic fertilisers.

The Trust does not want to take
agriculture back in time but would like to
retain working examples of the practices
that made the Tale Valley the beautiful      A new electric fence protects the repaired sluice and leat system from the

Could we restore Devon’s firs
We do not believe there is an example of a working bed-work water meadow system in
Devon. If we restore one small area of water meadow in the Tale Valley and can find a
team of volunteers to manage it a couple of times a year we may have the only working
example of this once commonplace winter activity!
