In the British countryside, alien species are not always undesirables | Mark Cocker

We suspect instinctive non-native species reinforces the moral vision of the binary nature

Imagine this autumn scene

Are the forest to find a basket of chestnuts. The fields involved in the green ears of barley and inaugurate, pheasants and partridges flush red while walking. A trio of hares Jinks far, its members and ears awkward fantastic dance all on the horizon. Rabbits bolting to cover all 10 steps and all old chestnut beam you are caught in the nice little yellow light reflector.

When the bird does not attract the eye away in SCUTS a dozen fallow deer trot anonymity deep wood. Few meters and there is your harvest chestnuts scattered on the ground as small green sputnik comes raining from space.

Can you think of a more rural scene inherently more typically English than that? And if you can not, think again. All elements of the imaginary landscape there before us. They are what ecologists call the non-native species. Barley was our Neolithic ancestors, hares and chestnuts were imported iron age, the Normans gave us deer, rabbits and pheasants, partridges came to the time of Charles II, while the owl had to wait for about a few followers of Victoria to its input. However, all are deeply rooted in our sense of the field.

Conditions
that these plants and animals awaken oblique comment on the current situation of the Orthodox environment, which does not allow the implementation of all non-native species. The release is still illegal aliens, their presence is always condemned and now the price of invasion was quantified economically, with a report earlier this week that the exotic wildlife in Europe unleashes € 12 billion damage years.
  • There are compelling reasons, no doubt, the current situation on foreigners. Our introduction of non-native plants and animals have had devastating consequences. The locus of classical chaos is isolated from the Hawaiian Islands is the perfect example. Biologically unique, this Pacific archipelago might have once 145 species of birds found nowhere else in the world. Today, there are still only 35 years, and 24 of them are in danger. A total of 22,000 plants and animals found Hawaiian on the islands, 4,373 are foreigners. However, the real villains of the invading horde in the paradise of Hawaii ecosystems are relatively few. These include domestic pigs, rats, mosquitoes, avian malaria protozoa and aptly named big head ant.
  • The problem with such an undeniable proof of the impact of foreign fatal is that it can lead to an instinctive response to all non-native species. This reinforces the binary moral vision of nature - Indian / foreign good / bad - an image that simplifies often complex
  • My previous scenario
    • chestnut hunting calls very well. Who would have thought that the chestnuts are now undesirable aliens? A wood Felbrigg, Norfolk, owned by the National Trust, where 300 years old reaching for the sky with great gnarled branches arthritis is one of the most beautiful forest areas of the country. Rabbits may have played hell with the interior of Australia, but they are essential for the maintenance and ecological environments lastgrassland British mow the lawn with her unrelenting incisors, creating perfect conditions for nesting birds ground and maintain floral diversity.
As the hare could even think spring comes to all, slapstick antics crazy creature? However, there is a mammal which holds more strongly for a nuanced approach to foreign invaders. The Chinese water deer is a primitive species labrador size with strangers fangs vampires who escaped in the landscape of East Anglia in the mid 20th century. Exotic as it may seem, this endearing creature swamp teddy bear is now part of the Broads environment. Where I live, winter nights are filled with the wild music of their courtship calls. Today, the population of foreign mammals can be critical to the existence of the species, given the dismal state of the deer in its native Asia. British Chinese water deer can always become the last hope of survival.

We must continue to bless the hare as a carrier of spring and learn to love the Chinese water deer as a permanent resident in our midst. Ultimately, however, we must avoid a general condemnation of "foreigners" and take each case - non-native species -. Depending on their individual merits
