For 30 years, in Europe there is a a significant decrease in the number of birds , inform the experts of the University of Exeter, The Royal Society for the Proteciton of Birds and the Pan-European Common Bird Monitoring Scheme (PECBMS). It was also noted that the increased abundance of some rare species of birds.
Studies have shown that over 3 decades of European bird population decreased by 421 million individuals. About 90% of the losses occurred among the 36 most common species, such as ordinary sparrow, Alauda, partridge or common starling. The rapid decline in the most widespread species is very worrying phenomenon because it is these species bring us many benefits – richard says Inger from the University of Exeter. We have more and more evidence that the proper interaction with the environment is essential to human welfare. The loss of a significant number of birds may adversely affect the society – adds.
Birds bring us a lot of benefits. They help control the population of pests, are very important carriers of seeds, scavengers play an extremely important role in the removal of dead animals from the environment. In addition, interaction with birds for many people favorite pastime – like watch them, listen to their singing or fatten.
Not all species experienced a decline. There has been an increase in the population of Marsh Harrier, Raven, myszłowa and kulonów. Probably has to do with programs to protect these species. Think so, Richard Gregory of the RSPB, which resembles that for example. The white stork and marsh harrier is one of the best-protected birds in Europe.
This study realizes the need for a shift in thinking about nature conservation. Usually we focus on fewer species and endangered. Here, however, we see that it is necessary to think and act globally, and protection should also include those species that are not currently threatened.
Experts say the most important causes of decline of birds are modern methods of land cultivation, growing pollution and fragmentation habitats. It is not known what is the relative influence of each of these factors individually.
The study was conducted on 144 species of birds from Europe. Used during these thousands of individual studies conducted in 25 countries.
