Why do we have to act
Alteration and destruction of habitats, pollution, unsustainable use of natural resources, threaten the survival of many species, Red squirrel, is a common species and widespread and does not have particular conservation risks. This, until the grey squirrel was imported, at different times and in different places, into Europe.
The similarity of names often indicates common habits, and such is the case for these two species of squirrels. They are so similar in their behavior and in their habitat preferences that they can not live together long; biologists summarize this phenomenon with a single word: competition. The red squirrel and the grey squirrel compete for space and food. Unfortunately, the result is always the same: the American grey squirrel remains and continues its expansion, the red squirrel becomes rare and in a short period of time, simply disappears for shortage of food resources. The evidence of this competition are evident in much of England and Wales, where the grey squirrel was introduced in the late nineteenth and the first decades of the twentieth century. Here the grey squirrel has colonized every available environment and the red squirrel is almost extinct from the British Isles.
The same is happening in Italy.
Extinction means total disappearance of a species from an area, where before it was present as a result of millions of years of evolutionary ongoing process and forger of what we commonly call biological diversity or biodiversity. The extinction of the red squirrel is a loss for forest, ecosystems in general ... and also for humans.
To prevent this disappearance is necessary to limit the spread of the grey squirrel!
These pages explain the mechanisms of competition between the two species, the possible future scenarios, the concerns of Europe and the reasons that underlie the project to save the Red Squirrel.
