Lee
Green Reservoir, Briercliffe/Worsthorne.
Grid
ref: SD880338
Lee
Green is a small area of water situated on the back road between Haggate and
Worsthorne below the larger Swinden Reservoir. This site`s importance seems to
lie in its unique combination of deep and shallow water, (with mud exposed
from time to time) and a mixture of reedbed willow, alder and sedge cover. Add
to this the surrounding farmland and gardens, lack of disturbance and the fact
that this combination of features which rarely
occurs at this altitude is adjacent to moorland and
what appears to be a migration route.
These
conditions make the site attractive to a wide range of species and seems to
add support to other local environments, therefore its protection must surely
be considered to be of prime importance. Over the past decade at least 115
species have been recorded, apparently taking advantage of its situation and
facilities either for breeding purposes or as a staging post during migration.
It is important therefore, not only locally, but has an effect on the
migration of birds over a wider area, proving a busy wintering refuge for many
species.
The
area is covered by a small but regular band of local birders who have found a
large degree of perseverance is often required.
The
reservoir is surrounded by a wall and is best viewed from the path running
along the southern side and the dam. In
past years concern was expressed by the Water board on the condition of this
dam which led to significant lowering of the water level allowing the top end
to dry out quickly.
The
continuing silting and encroachment of the reed beds at the waters edge has
led to the area of dry land to steadily increase and therefore improve the
habitat for breeding and passage warblers.
Late summer finches and Roe Deer sighting are also not uncommon in this
area.
The
presence of the wall has helped to minimise disturbance in the old reservoir
basin but can cause observers to be silhouetted and easily spotted by ducks
and occasional waders, the main advantage of the wall however is it offers
good point to lean on along the reservoir length.
As
a walk, the path along the Reservoir is relatively short but can easily be
incorporated into walks through Hagg Wood to Heasandford and Rowley or on to
the higher moorlands and moorland fringe of Swindon, Extwistle moor or the
wooded valley at Thursden.
This
list attempts to show the status of birds at Lee Green reservoir over the last
decade, some of the rarer passage birds may have only been recorded on one
occasion whilst many species are present on a daily basis. The records have
been compiled by Malcolm Higgins and birdwatchers who observe the area on a
very regular basis. Reference was also made to East Lancashire Ornithologists
Club’s annual bird reports for the period covered.
