RESEARCH: The West European Hedgehog is common in mainland Europe but classified as vulnerable in the United Kingdom

The West European Hedgehog is common in mainland Europe but classified as vulnerable in the United Kingdom – in danger of becoming extinct. Why is this the case?

In Europe, the brownish-white West European Hedgehog (Erinaceus europaeus) is widespread and found from Portugal to Russia. Researchers think that the numbers are high because hedgehogs have a varied diet with an abundant choice in mainland Europe.

However, in the United Kingdom, the numbers of West European Hedgehogs have declined significantly although exact numbers are not available. Scientists think that one main reason may be the high number that are killed on the roads – which is estimated to be thousands each each. In addition, modern farming methods and few hedgerow plants might also contribute to the declining numbers in the United Kingdom.

City animals are changing their physical characteristics

Evolutionary biologist Rob Dunn, in his 2022 book A Natural History of the Future maintains that evolution can occur quicker than people think – mostly unnoticed, right under our noses. Evolution is happening when the physical characteristics of animals change over time, or new types of animals develop, or some animal species disappear.

Rob Dunn first explains how animal species can evolve and change. One way is through isolation – when animals are separated from other species, they can diverge and change some of their physical characteristics. Another way is through a change of diet, and another way is through geographical barriers.
