The Swedish ecologists have revived population of a sea eagle in the country - belohvosta
the Swedish ecologists celebrate important victory. As a result of the unique project the largest feathery predator is rescued from disappearance in Northern Europe - a sea eagle - belohvost.
we Will remind that 40 years ago sea eagles - belohvosty and sapsany perished from environmental contamination by chemicals.
“ In the beginning 70 - h years at east coast of Sweden units of sea eagles - belohvostov were only. On shherah it was possible to conduct supervision by weeks and not to see any of them. How this kind is reproduced today, simply impresses “ - biologist Per Bengtson from the Society of wildlife management of Sweden marks.
When feathery predators have appeared under the threat of disappearance the wildlife management Society became the initiator of the special project on their rescue. Almost 40 years on end ecologists conducted regular supervision over distribution of polluting substances and traced their influence on ecology. These researches contributed in an interdiction for use in Sweden DDT in 1975 and polychlorinated difenilov in 1979.
Recently journalists of Swedish television SVT have embodied whole “ a band “ these birds over a dump in suburb of Stockholm Huddinge. Though usually sea eagles nest at sea coast, at lakes and the rivers where, as a rule, it is a lot of fish.
Now municipality Huddinge thinks even to organise excursions for interested persons to observe habits rare before a bird which wingspan can reach 2,5 metres.
Annually number of sea eagles register in Sweden in 60 places - along lakes Melaren and Elmaren. This year ecologists have counted here almost 150 sea eagles - belohvostov and golden eagles that 10 times more, than last years.
“ But it is not necessary to forget that much will depend on the further level of polluting substances in environment “ - marks Sten Ullerstad supervising population of birds.
In 2001 in an organism Swedish sapsanov have found out traces of dangerous chemical substances, informs the Swedish radio.
