Aarhus Universitet, DCE – Nationalt Center for Miljø og Energi, 350 s. - Videnskabelig rapport nr. 420. http://dce2.au.dk/pub/SR420.pdf Gengivelse tilladt med tydelig kildeangivelse Sammenfatning: I denne rapport fremlægges resultaterne af overvågningen af fugle i NOVANA for årene 2018-2019. Endvidere beskrives langtidsudviklinger for overvintrende bestande af knopsvane, ænder og blishøne tilbage til 1960’erne og for gæs og gulnæbbede svaner til 1980’erne. For ynglende arter beskrives udviklingen for de fleste arter tilbage til NOVANA programmets start i 2004. Rapporten giver for fuglearter, der er omfattet af NOVANA-programmet, en opdateret dokumentation for de data der var grundlag for afrapporteringen af bestandsudviklinger i forbindelse med Artikel 12 afrapporteringen vedr. Fuglebeskyttelsesdirektivet i 2019. Den nationale overvågning har omfattet ynglefugle samt rastende og overvintrende fugle omfattet af Fuglebeskyttelsesdirektivet. I overvågningen har indgået et specielt program for Vadehavet i henhold til det Trilaterale Vadehavssamarbejde.

Dette er 2. udgave af rapporten, der i forhold til 1. udgave er opdateret med resultater for flere ynglefuglearter samt for trækfuglenes vedkommende opdateret med trends for svømmeænder optalt i oktober. 3 Forord Denne rapport udgives af DCE - Nationalt Center for Miljø og Energi, Aarhus Universitet (DCE) som et led i den landsdækkende rapportering af det Nati- onale program for Overvågning af VAndmiljøet og NAturen (NOVANA). NOVANA er fjerde generation af nationale overvågningsprogrammer, som med udgangspunkt i Vandmiljøplanens Overvågningsprogram blev iværksat efteråret 1988. Nærværende rapport omfatter data til og med 2019. Bemærk at denne udgave af rapporten er en computergenereret version af en internet-baseret afrapportering, som findes på adressen http://no- vana.au.dk/fugle/. Hvis rapporten læses på internettet, er der mulighed for at se alle figurer og diagrammer i betydeligt bedre opløsning og størrelse samt udnytte indbyggede hyperlinks, der henviser til interne dele af rapporten samt eksterne referencer. Overvågningsprogrammet er målrettet mod at tilvejebringe det nødvendige dokumentations- og vidensgrundlag til at understøtte Danmarks overvåg- ningsbehov og -forpligtelser, bl.a. i forhold til en række EU-direktiver inden for natur- og miljøområdet. Programmet er løbende tilpasset overvågnings- behovene og omfatter overvågning af tilstand og udvikling i vandmiljøet og naturen, herunder den terrestriske natur og luftkvalitet. DCE har som en væsentlig opgave for Miljøministeriet at bidrage med forsk- ningsbaseret rådgivning til styrkelse af det faglige grundlag for miljøpolitiske prioriteringer og beslutninger. Som led heri forestår DCE med bidrag fra In- stitut for Bioscience og Institut for Miljøvidenskab, Aarhus Universitet den landsdækkende rapportering af overvågningsprogrammet inden for områ- derne ferske vande, marine områder, landovervågning, atmosfæren samt ar- ter og naturtyper. I overvågningsprogrammet er der en arbejds- og ansvarsdeling mellem fag- datacentrene og Miljøstyrelsen (MST). Fagdatacentret for grundvand er pla- ceret hos De Nationale Geologiske Undersøgelser for Danmark og Grønland (GEUS), fagdatacentret for punktkilder hos MST, mens fagdatacentrene for vandløb, søer, marine områder, landovervågning samt arter og naturtyper er placeret hos Institut for Bioscience, Aarhus Universitet og fagdatacentret for atmosfæren hos Institut for Miljøvidenskab, Aarhus Universitet. Denne rapport er udarbejdet af Fagdatacenter for Biodiversitet og Terrestrisk Natur. MST har haft mulighed for at kommentere på udkast til rapporten. Rapporten er baseret på data indsamlet af MST og DCE, suppleret med data indsamlet af Dansk Ornitologisk Forening (DOF). Data fra DOF er kvalitets- sikret af MST (Intensiv 2-overvågning af ynglefugle) og DCE (trækfugle). Dette har særligt fokus på data indsamlet i 2018 og 2019, men præsenterer også data for tidsserier der rækker tilbage til henholdsvis 1960’erne (overvint- rende knopsvane, ænder og blishøne) og 1980’erne (gæs og gulnæbbede sva- ner) og er som udgangspunkt en opdatering af tidligere års rapport om fug- leovervågningen med nye data. Den seneste rapport er Fugle 2012-2017 (Ni- elsen m.fl. (2019), der præsenterede grundlaget for Danmarks rapportering af fugle i medfør af fuglebeskyttelsesdirektivets artikel 12 er vist. Sidstnævnte er sammenfattet af Fredshavn m.fl. (2019). 4 Rapporten beskriver udviklingen i den overordnede tilstand, men forholder sig ikke til mål- og tilstandsvurderinger i henhold til fx EU-direktiver. Disse vurderinger vil fremgå af relevante Natura 2000-planer for fuglebeskyttelses- områderne, der udgives af MST. Konklusionerne i denne rapport sammenfat- tes med konklusionerne fra de øvrige fagdatacenter-rapporter i ’Vandmiljø og natur 2019’, som udgives i et samarbejde mellem DCE, GEUS og MST. ’Vandmiljø og natur 2019’ afventer, at der foreligger rapporter fra alle fag- datacentre, og da rapporten fra fagdatacenter for landovervågning, samt dele af rapporterne om søer, vandløb og marine områder afventer afklaring af pro- blemer med nedbørsmålinger og dermed mulighed for at opgøre den samlede stoftransport, vil ’Vandmiljø og natur 2019’ også afvente dette. 5 Sammenfatning Med igangsættelse af det Nationale program for Overvågning af VAndmiljø og NAtur (NOVANA) har Danmark fra 2004 fået en systematisk overvågning af de fugle, der udgør udpegningsgrundlaget for fuglebeskyttelsesområderne og er beskyttet i henhold til Fuglebeskyttelsesdirektivet. I henhold til dette direktiv og Habitatdirektivet er der udpeget et netværk af særlige beskyttel- sesområder, kaldet ”Natura 2000-områder” som rummer arter og naturtyper, herunder fugle, der har behov for beskyttelse inden for den Europæiske Union. For disse områder gælder det generelt, at de skal medvirke til at sikre den biologiske mangfoldighed både på nationalt og europæisk plan. Delprogrammet for overvågning af fuglearter i NOVANA har det primære formål at overvåge de enkelte arters udbredelse og bestandsstørrelse samt ud- viklingsretning for at tilvejebringe et fagligt grundlag for at vurdere de en- kelte arters bestandsudvikling både inden for og uden for fuglebeskyttelses- områderne og styrke den faglige baggrund for eventuelle foranstaltninger, der vurderes at ville kunne forbedre den enkelte arts status. Overvågningen af fugle er gennemført for perioden 2004-2019 og omfatter dels alle de regelmæssigt forekommende ynglefuglearter, som er optaget på Fuglebeskyttelsesdirektivets bilag I, dels alle de trækfuglearter, som ligeledes indgår i udpegningsgrundlaget for et eller flere fuglebeskyttelsesområder. Denne rapport præsenterer resultaterne af overvågningen foretaget i årene 2018-2019, som er sket under NOVANA. Artsgennemgangen præsenterer ar- ternes status, som den tegnes af det indsamlede overvågningsmateriale. Da Danmark i 2019 afrapporterede en database til EU-kommissionen i medfør af Fuglebeskyttelses-direktivets

GEOLOGY Extreme storms and storm surges may induce major changes along sandy barrier coastlines, potentially Received causing substantial environmental and economic damage. We show that the most destructive storm (the 1634 10 August 2012 AD storm) documented for the northern Wadden Sea within the last thousand years both caused permanent barrier breaching and initiated accumulation of up to several metres of marine sand. An aggradational storm Accepted shoal and a prograding shoreface sand unit having thicknesses of up to 8 m and 5 m respectively were 26 November 2012 deposited as a result of the storm and during the subsequent 30 to 40 years long healing phase, on the eroded shoreface. Our results demonstrate that millennial-scale storms can induce large-scale and long-term changes Published on barrier coastlines and shorefaces, and that coastal changes assumed to take place over centuries or even 23 January 2013 millennia may occur in association with and be triggered by a single extreme storm event.
  • Do Local Adaptations Affect the Conservation Release Program of the Green Toad, Bufo Viridis in Sweden?

    Do Local Adaptations Affect the Conservation Release Program of the Green Toad, Bufo Viridis in Sweden?

    Do local adaptations affect the conservation release program of the green toad, Bufo viridis in Sweden? Axel Berglund Degree project in biology, Master of science (1 year), 2009 Examensarbete i biologi 30 hp till magisterexamen, 2009 Biology Education Centre and Department of Population Biology, Uppsala University Supervisors: Jacob Höglund and Björn Rogell Table of contents Abstract 2 Sammanfattning 3 Introduction 4 Materials and methods 6 Results 9 Discussion 15 Acknowlegments 17 References 17 1 Abstract Globally, amphibians are declining at an alarming rate. The reasons are not always known but human activities are believed to be the primary reason. In Sweden the Green Toad, Bufo viridis, is currently the most threatened amphibian species and has been the focus of extensive conservation efforts. Habitats have been restored or improved and eggs, tadpoles and juvenile toads have been released at these sites. Despite all efforts results have so far been poor. In this study I have examined if different B. viridis localities differ from each other in respect of salinity and temperature in the breeding ponds, and if the tadpoles are locally adapted to these environmental factors. The results show that there are significant environmental differences between the localities in respect to salinity and temperature, and that tadpoles from different localities respond differently to salinity and temperature. However, I was not able to find any correlations between the performance in the laboratory and the natural environment suggesting the differences are not due to local adaptations but something else. Further implications for the conservation for the Swedish B. viridis population are discussed in light of the results.
  • Its Role in Realising the Bridge and Tunnel Connection Between Denmark and Sweden Mette Thorkilsen and Claus Dynesen

    Its Role in Realising the Bridge and Tunnel Connection Between Denmark and Sweden Mette Thorkilsen and Claus Dynesen

    105 © IWA Publishing 2001 Journal of Hydroinformatics | 03.2 | 2001 An owner’s view of hydroinformatics: its role in realising the bridge and tunnel connection between Denmark and Sweden Mette Thorkilsen and Claus Dynesen ABSTRACT The motorway and railway connection between Denmark and Sweden, opened on 1 July 2000, when Mette Thorkilsen Project Manager, taken together with the connection across the Great Belt between the largest Danish islands, now Environment, provides a direct link between the Scandinavian peninsular and the rest of Europe. At a total cost of Øresundsbro Konsortiet some 8 billion US dollars, these projects represented the largest infrastructural investments of their Claus Dynesen Project Director, kind in Europe. Although backed by strong political and economic interests, these projects were also Environment & Authorities, Øresundsbro Konsortiet opposed by a part of the public and especially by political and environmental interest groups. This opposition was particularly pronounced in the case of the Denmark-Sweden link, partly owing to its location in a densely populated area and partly due to the potential impacts of the proposed link on the very sensitive local and regional marine environment. Thus, alongside the task of designing and constructing the physical link, the consortium that was responsible for its realisation, Øresundsbro Konsortiet, had to find ways to satisfy these many diverse interests. This paper describes how Øresundsbro Konsortiet, being an owner that valued constructive partnership, took up these challenges in their management, and how the environmental concerns were accommodated in the design and construction methods. Furthermore, it describes how the socio-technical approaches already taken up and developed within hydroinformatics in earlier projects were taken much further in the case of the Denmark-Sweden link.

Kongedybet Hollænderdybet Middelgrunden Saltholm Flak 2 From Idea to Reality The idea of the Middelgrunden wind project was born in a group of visionary people in Copenhagen already in 1993. However it took seven years and a lot of work before the first cooperatively owned offshore wind farm became a reality. Today the 40 MW wind farm with twenty modern 2 MW wind turbines developed by the Middelgrunden Wind Turbine Cooperative and Copenhagen Energy Wind is producing electricity for more than 40,000 households in Copenhagen. In 1996 the local association Copenhagen Environment and Energy Office took the initiative of forming a working group for placing turbines on the Middelgrunden shoal and a proposal with 27 turbines was presented to the public. At that time the Danish Energy Authority had mapped the Middelgrunden shoal as a potential site for wind development, but it was not given high priority by the civil servants and the power utility.

    Production of Edible Seaweed Flags: Danish Small Islands & Bornholm Islands of Anholt, Fejø, Skarø, Årø, Bjørnø, Ertholmene, Bornholm, Thurø (Denmark)

    European Commission Project Case Study Production of edible seaweed FLAGs: Danish Small Islands & Bornholm Islands of Anholt, Fejø, Skarø, Årø, Bjørnø, Ertholmene, Bornholm, Thurø (Denmark) Project overview Anholt This project involves cooperation between stakeholders from two Danish FLAGs, one on the island of Bornholm and the other covering DENMARK SWEDEN smaller islands, in commercially exploiting sea- weed, an overlooked resource in Danish waters. Arø Ertholmene By promoting the sustainable cultivation, har- Thurø Bornholm vesting and processing of seaweed, the project Bjørnø Skarø will assist in diversifying the local economies of Fejø the islands, thereby helping to maintain strong local populations and vibrant communities. GERMANY Context and Key Challenges The small Danish islands and Bornholm are remote areas, threatened by depopulation and a loss of business opportuni- ties. Seaweed production presents a potential new opportu- nity for local entrepreneurs, including fishermen. If exploited successfully, it could help to broaden the range of products offered locally and lead to increased earnings for local food producers and restaurants. While there is no tradition of cultivating, harvesting, or exploiting seaweed in Denmark, with the growing popularity of sushi and the development of the New Nordic Cuisine, Danish seaweed is increasingly in demand. Danish waters pro- duce, or can produce, similar seaweed species to those grown in East Asia or in the Atlantic. The quality of this seaweed is excellent, and for some purposes even better than imported dried seaweeds because of the limited salinity levels in some parts of the Danish waters. Many of the 27 small Danish Islands with less than 1 000 inhabitants are, together with Bornholm, well known for food production.

    555 the Regime of Passage Through the Danish Straits Alex G. Oude

    The Regime of Passage Through the Danish Straits Alex G. Oude Elferink* Netherlands Institute for the Law of the Sea, Utrecht University, The Netherlands ABSTRACT The Danish Straits are the main connection between the Baltic Sea and the world oceans. The regime of passage through these straits has been the subject of extensiveregulation, raising the question how different applicable instruments interact. Apart from applicable bilateral and multilateral treaties, it is necessaryto take into account the practice of Denmark and Swedenand other interested states, and regulatory activities within the framework of the IMO. The Case ConcerningPassage Through the Great Belt before the ICJ provides insights into the views of Denmark and Finland. The article concludesthat an 1857treaty excludesthe applicabilityof Part III of the LOS Convention to the straits, and that there are a number of difficultiesin assessingthe contents of the regimeof the straits. At the same time, these uncertaintiesdo not seem to have been a complicatingfactor for the adoption of measuresto regulate shipping traffic. Introduction The Danish Straits are the main connection between the Baltic Sea and the world oceans. The straits are of vital importance for the maritime communication of the Baltic states and squarely fall within the legal category of straits used for international navigation For a number of these states the Baltic Sea is the only outlet to the oceans (Estonia, Finland, Latvia, Lithuania and Poland).
