|Farming has changed beyond all recognition in the last
60 years. World War II provided the impetus to take as much land as possible into
cultivation, to feed a population cut off from traditional supply routes. Such has been
the continuing pressure that even those areas unsuitable for agriculture without a great
deal of remedial work, have been altered and pressed into service to feed our ever-growing
population. In the 1930's, Britain's farmers produced enough food to feed 16 million
people. Today, they produce enough to feed 40 million people. People need to be fed.
As a result, many habitats that were once common have dwindled into sad remnants of their
Meadows are a habitat created by centuries of
traditional farming practices. They are low input, low output systems for feeding
relatively small numbers of cattle and sheep. Increasing economic pressures on farmers
mean that cattle and sheep must be kept in ever increasing concentrations in order to
produce a profit. In addition, the advent of BSE has meant that animals over 30 months old
cannot enter the human food chain. All beef cattle must therefore be reared to suitable
weights as rapidly as possible. In order to do so, they have to be fed large quantities of
high quality food.
This means that most grass pastures are managed intensively to
produce the best crop of grass possible, either for direct grazing, or for the production
of the winter feed known as silage. Intensive cultivation of grasslands has allowed
farmers to improve their grass yields from about 1 tonne an acre to 15 tonnes. To achieve
this, special cultivated grass varieties are sown, fertilizers are applied in large
quantities and herbicides are commonly used. All of this will prevent the
development of meadows and their greater diversity of life. Meadows survive only where it
is too uneconomic to manage them intensively, usually because of inhospitable terrain, or
Ninety seven percent of the meadows present in the 1940's, have now
disappeared, along with vast areas of habitat for a great diversity of plants and animals.
Not all of the losses are due to changes in the intensity of farming. The increasing need
for space for spreading human populations and more rarely the lack of management of
meadows so that scrub and woodland take over, are all factors in their decline.
||All is not totally lost. A few farmers still manage a
part or all of their farm in more traditional ways and on these, hay meadows in all their
glory will still be found.
Agricultural subsidy schemes,
which encourage farmers to manage areas in more environmentally sensitive ways in return
for cash benefits, are becoming more widespread. It is also possible to recreate or
restore wild flower meadows, where they once existed, or on new areas. However a
significant problem with this, is restoring areas to low fertility where they have been
Meadows, as old ecosystems, are also complex areas and it takes a
great deal of time for a stable meadow ecosystem to be restored.
