Tales from the Country Factsheet – Ep3 of 10
7.30pm 18th January 2007 ITV1 Anglia and London
This
week’s episode looked at life for the invaders, that group
of plants and animals from over there doing very nicely over here.
First
up in the programme was the mink – a native American if ever
there was one. The mink was brought over from the USA in 1929 to
be farmed for its fur. Numerous escapes – some deliberate,
some not – later the mink had found its way into the British
countryside.
The
mink has no natural predators here in the UK, although otters have
been known to ‘take’ mink. But the decline of the otter
during the last 50 years, have meant one less barrier for the mink
to overcome. In such conditions the animal has flourished.
A
mink will eat a wide range of prey from eels to rabbits. It is thought
the mink has had a devastating effect on the native population of
water voles in the UK. The vole makes it home deep in riverbank
burrows.
Unfortunatley
these burrows are mink sized and provide a perfect food source for
the American invader. Action is being taken in an attempt to curb
mink numbers and the effect they have on the wider wildlife.
Japanese
knotweed, now known as a ‘superweed’, was lauded when
it first came to the UK.
The
man we have to thank was one Phillip Von Siebold, a Bavarian physician
in the Dutch East Indies Army who brought the plant back to Europe
in the mid-18th Century.
From
there cuttings were introduced into England, with the ‘London
Horticultural Society’ obtaining its first specimen in 1825,
and the plant won a award for the “most interesting newcomer”
at a European flower festival.
Thanks
to its fast growing nature the plant was used to cover Victorian
privies. Knotweed was being hailed as a wonder plant. Then it began
popping up across the country where it was not wanted.
Amazingly
all of the Japanese Knotweed plants in Europe are female, and all
can be traced back directly to Von Siebald’s original plant.
Such is the growth of the knotweed that it is only absent in the
Orkney Islands within the whole of the UK.
CABI,
is a not for profit organisation dedicated to the study of ‘life
sciences’ Amongst their projects is a Berkshire based study
into Japanese Knotweed, and CABI scientists are attempting to find
a bug or a disease which will kill the knotweed once and for all.
Tests are ongoing at present within a mini-version of Japan, where
chunks of knotweed are being assaulted by insects and blights of
various incarnations.

For
more on Japanese Knotweed take a look at the ‘Japanese Knotweed
Alliance’ website – which comes complete with recipes!

A
number of companies specialise in the removal of Japanese Knotweed
from commercial sites. Such is the weeds hardiness, it can take
3 years worth of spraying to kill it off. An alternative is to dig
the weed out. But with roots plunging deep into the ground this
can be a long and laborious process.
The
company we featured working on a site was the Brighton based Phlorum.

Finally
the programme was in the fens to look at the history of the zander
and how this fish came to inhabit our rivers and canals. The zander,
a predatory fish native to Eastern Europe, was first brought to
the UK by the 9th Duke of Bedford back from Germany to his home
at Woburn.
The
23 fish remained in his lake at the country estate, joined by some
more in 1910 when the 11th Duke followed suit.
Come
the early 1960’s and the then Great Ouse River Board decided
to stock some zander in the river to provide new sport for anglers.
By 1975 the zander had colonised the whole catchment area, and as
a fish-eating fish, the zander was soon public enemy number 1 in
the eyes of some anglers blaming it for falling stocks.
Other
anglers though were entranced by this new addition to our waterways.
Many were moved under cover of night and slipped into the canal
network to provide new sport for anglers away from the fens. The
zander thrived in the murky canals thanks to its reflective retina
allowing it so see in very poor light conditions.
In
some places culls still take place in relation to the zander, but
these are becoming increasingly rare as the zander is left to its
own devices, and cleaner rivers allow other species to thrive alongside
it.
In
the programme Tony fished with zander expert Mark Barrett. He offers
tours of the Fens as an angling guide for those looking to fish
for zander. For more on Mark visit www.kestrelguides.co.uk

Tony
also spoke with Neville Fickling, a legendary zander fisherman.
Nevillle, who owns a tackle shop in Gainsborough, even wrote a book
on the subject entitled Zander. |
