Prvi rezultati telemetrijskog praÄenja zmijara Circaetus gallicus u Hrvatskoj
Zmijar Circaetus gallicus je gnjezdarica selica Europe koja zimuje u sjevernim tropima Afrike, južno od Sahare. VeÄina jedinki na migraciji bira glavne selidbene puteve, preko Gibraltara i Sueskog kanala. Kako bi saznali kojim se selidbenim putem služe ptice hrvatske
populacije, obilježili smo mladog zmijara GPS ureÄajem 27.7.2017. u Parku prirode TelaÅ”Äica. Zmijar je na selidbu krenuo 18.9.2017. i u iduÄih 25 dana je preletio 6054 kilometara, birajuÄi istoÄni selidbeni put preko GrÄke, Turske, Sirije, Libanona, Jordana, Egipta i Äada, sve do Sudana gdje je zimovao
Stradavanje prvog surog orla Aquila chrysaetos obilježenog satelitskim odaÅ”iljaÄem u Hrvatskoj
Suri je orao gnjezdarica priobalne i gorske Hrvatske. Zbog opÄenite malobrojne nacionalne populacije i sve veÄeg pritiska, prije svega vjetroelektrana u Dalmaciji, ova je vrsta ugrožena i potrebno je pratiti sudbine surog orla na razini jedinke. Razvojem satelitske telemetrije omoguÄena su praÄenja mladih ptica Äija je disperzija bila dosad slabo istražena. 29.4.2017. poÄelo je praÄenje prve jedinke surog orla obilježene u Hrvatskoj. GPS-GSM ureÄajem obilježen je mladi mužjak porijeklom s Promine oporavljen od posljedica prostrjeljivanja koji je puÅ”ten u prirodu u Parku prirode Krka. PraÄenje orla trajalo je malo viÅ”e od dva mjeseca kad su ureÄaj i ostaci ptice pronaÄeni u blizini vjetroagregata kod BruÅ”ke. Gotovo je sigurno stradao od sudara s elisom vjetroagregata. Nakon prvotnog istraživanja veÄeg podruÄja, veÄinu vremena suri se orao zadržavao u okolici Gornjih Biljana i Gornjeg Karina. S obzirom na to da se suri orao zadržavao gotovo osam mjeseci na tom podruÄja, smatramo da se radi o teritoriju nedorasle jedinke i upuÄuje na važnost identifikacije takvih podruÄja za uÄinkovitu zaÅ”titu surog orla
Land use and Europeās renewable energy transition: identifying low-conflict areas for wind and solar development
Continued dependence on imported fossil fuels is rapidly becoming unsustainable in the face of the twin challenges of global climate change and energy security demands in Europe. Here we present scenarios in line with REPowerEU package to identify Renewables Acceleration Areas that support rapid renewable expansion, while ensuring minimal harm to places important for biodiversity and rural communities. We calculated the area needed to meet renewable energy objectives under Business-as-Usual (BAU) and Low-conflict (LCON) development scenarios within each country, providing a broad overview of the potential for renewable energy generation to reduce impacts when development is steered toward lower conflict lands. Our analysis shows that meeting renewable energy objectives would require a network of land-based wind turbines and solar arrays encompassing upwards of 164,789Ā km2 by 2030 and 445,654Ā km2 by 2050, the latter roughly equivalent to the land area of Sweden. Our results highlight that BAU development patterns disproportionately target high-conflict land cover types. By 2030, depending on the development pathway, solar and wind development are projected to impact approximately 4,386ā20,996Ā km2 and 65,735ā138,454Ā km2 of natural and agricultural lands, respectively. As renewable energy objectives increase from 2030 to 2050 impacts to natural and agricultural lands also increase, with upwards of 33,911Ā km2 from future solar development and 399,879Ā km2 from wind development. Despite this large footprint, low-conflict lands can generate substantial renewable energy: 6.6 million GWh of solar and 3.5 million GWh of wind, 8ā31 times 2030 solar objectives and 3ā5 times 2030 wind objectives. Given these patterns, we emphasize the need for careful planning in areas with greater impact potential, either due to a larger demand for land area or limited land availability. Top-emitting countries with large renewable energy objectives (Germany, Italy, Poland, France, Spain) and those with limited flexibility in meeting objectives on low-conflict land (Albania, Slovenia, Montenegro, Hungary, Croatia, Serbia, Bosnia Herzegovina, Finland, Greece, Portugal, and Norway) should be priorities for country-level customizations to guide low-conflict siting and avoid disproportionate impacts on high-value areas
The EuroBirdPortal: current state of the project and its outputs
The EuroBirdPortal (EBP) project combines the data collected by the different online bird portals oper-
ating in Europe. These portals aim mainly to obtain year-round data from the relatively unstructured but
intensive and widespread activities of birdwatchers, collecting vast amounts of data that offer great
potential to better understand the temporal and spatial distribution of birds. All in all, the portals contrib-
uting to the EBP have collected more than 445 million bird records since 2010. In 2020 alone, 56 million
bird records were collected and the annual figure keeps increasing by c. 14% year after year. Data is
also increasing qualitatively. Currently, 34% of the whole EBP comes from complete or fixed lists and,
overall, the submission of lists is increasing by c. 13% each year. On the other hand, more and more
portals collect standard monitoring data (e.g. breeding bird surveys) or use specific data collection pro-
tocols (e.g. nocturnal flight calls) and submit such data to the EBP correctly identified and characterized
making full use of the capabilities of the EBP data standard. The availability of the data collected in near
real-time is one of the main added values of the EBP project. Currently, 17 out of the 20 online systems,
accounting for 99.5% of all the data collected, submit data to the EBP automatically, on a daily basis
and updated up to the previous day. The EBP provides information on the patterns of bird distribution
(historic and real-time) for a selection of 137 bird species through the EBP viewer (www.eurobirdpor-
tal.org). Moreover, by combining its data with other continent-wide datasets (e.g. bird ringing data from
EURING) the EBP is giving further applied value to the data collected by the online bird portals in such
important areas as the surveillance of avian-borne diseases
