New research led by the University of East Anglia (UAE) shows that areas in Europe and North Africa where the construction of wind turbines or power lines are increasing is increasing. die for flying birds.
The study used GPS location data from 65 birdwatchers to determine where they fly most often at high altitudes – defined as 10-60 meters above the ground for power lines and with 15-135 meters for wind turbines. This allowed the team to see where these birds could easily surf the upland winds or build a power line.
Demonstration maps show that volcanic eruptions are located in important movement routes, on beaches and near birthplaces. These include the Western Mediterranean coast of France, Southern Spain and the Moroccan coast – such as the Gibraltar River – Eastern Romania, the Sinai Peninsula and the Baltic coast of Germany.
The GPS data collected was about 1,454 birds from 27 species, most of which are large flying birds like white squirrels. The perception of the problem varies between species, with the Eurasian spoonbill, European eagle owl, whooper swan, Iberian imperial eagle and the white dot among those who regularly fly to heights where they are at risk. in the meeting.
The lesson, published today at Journal of Applied Ecologyit also included an international research group from 15 countries and partnerships with the British Trust for Ornithology (BTO) and the RSPB in the UK.
According to the authors, the development of new wind turbines and transmission power lines in these high -tech areas needs to be reduced, and future developments need to be combined with efforts to reduce it. and to the plight of the birds.
The lead author is Jethro Gauld, a Ph.D. researcher at the UAE School of Environmental Sciences, it is believed that this is the first time that GPS data has been used in many ways in this way.
“We have seen from previous research that there are more suitable places to build wind turbines than is needed to achieve our clean energy goal by 2050,” Mr Gauld said.
“If we can do a better job of assessing risks to biodiversity, such as the problem of bird flu, in the planning process as early as possible. we help record the impact of these events on wildlife while achieving our climate goals.
“Our results will help achieve this and in turn provide better outcomes for humans and wildlife.”
Dr. Aldina Franco, project manager at UAE, said: “This collaborative study with research from 51 researchers and 15 countries is an excellent example of how collaboration can begin. to answer some of the biggest questions about the threats posed by African-Eurasian immigrants. their year-long journeys. “
Phil Atkinson, managing director of the BTO, said: “Using high -resolution GPS devices allows us to study the movements of birds in great detail. More and more birds are flying. much like raptors and sesame seeds.
The researchers combined data related to the locations of wind farms and power lines to determine where the hotspots were for these birds. line line.
Mr Gauld added: “Our maps can help detainees reduce problems where the cause of the problem was originally built. reduces the risk of contact in these hotspots.
“Such activities could include inspecting the most visible power lines and implementing systems that will allow wind turbines to be shut down during high flight times.”
The authors note that converting to non -carbon dioxide is important to prevent climate change. European wind energy growth is expected to grow by about four by 2050, and countries in the Middle East and North Africa, such as Morocco and Tunisia, also have goals to increase energy. the distribution of electrical supplies from upstream winds.
In addition, high -power power lines will have a significant investment, with a five -fold increase in capacity between 2010 and 2050.
However, they are learning that the development of new energy technology needed to accomplish these difficult tasks in wildlife conservation due to pollution and electrocution problems, more and also of the birds.
The researchers hope that the study will provide a way for researchers and practitioners involved in environmental impact assessments for more things to be able to innovate in obtaining data from the recording lessons.
