Sustainable
erosion control
Hazel Corylus avellana is
a small deciduous tree which has been coppiced for generations to
produce multiple straight stems. It is hardy, moderately shade tolerant
and grows best on heavy well drained soils. Hazel is found everywhere
in the British Isles though a significant proportion of old coppices
have been neglected and are now out of cycle.
Male and female flowers grow
on the same plants but do not self pollinate. The male catkins open
as the first warm days of spring arrive to form drooping bunches
of bright yellow "lambs tails". The fertilised flowers
develop into clusters of hazelnuts which turn brown in October.
Hazelnuts are a very important source of food for the native dormouse
and are indeed regularly used as the basis for population surveys.
Hazel is usually coppiced on
a 7-15 year cycle and JPR Environmental are now
managing a coppice at the WWT reserve Slimbridge.
Hazel has many uses, its stems
split and twist easily so it can be woven to make hurdles in the
same way as willow. At JPR Environmental we are using hazel
as the upright stakes in the production of our willow hurdles.
We are also using hazel in the form of faggots as part of
our erosion control service.
Hazel faggots are 2 m bundles
of hazel, between 300 and 400 mm in diameter and tied in three places.
The faggots are used in conjunction with other materials such as
coir rolls in the re-establishment and repair of river banks. They
are placed below the minimum water level to form a barrier. As they
encourage siltation the banks begins to reform around them. Coir
rolls can then be placed on top, secured and planted to form a vegetation
shelf to provide a good habitat for wildlife including water voles,
frogs, fish, kingfishers and dragonflies. Hazel faggots are also
used to redirect river flow and therefore prevent erosion by placing
and securing them on the riverbed. This also provides shelter against
the river flow current for invertebrates which provide a source
of food for larger species of fauna.
JPR
Environmental can supply and install hazel faggots across
the UK. Please contact us if you would like to discuss
riverbank erosion and using hazel faggots to prevent it.
