Povzetek: Pilotna akcija “Revizija biodiverzitete v kopenskih, negozdnih okoljih Krajinskega parka Ljubljansko barje« je bila izvedena v okviru projekta "Od podatkov o biodiverziteti do odločanja" (Interreg Evropa; BID-REX; 2016-2021). Projekt BIDREX je naslavljal problematiko uporabe podatkov o biodiverziteti v procesih odločanja na področju varstva narave. Namen pilotne akcije je bil testirati metodo »Revizija biodiverzitete«, ki so jo razvili na Univerzi Vzhodne Anglije in uspešno uporabili že na treh naravovarstveno pomembnih območjih Velike Britanije. Osnovni cilj pilotne akcije je bil ugotoviti, katero biodiverziteto in kako uspešno jo varujejo trenutni naravovarstveni ukrepi na Ljubljanskem barju, s poudarjenim pogledom na shemo Kmetijsko-okoljsko-podnebna plačila (KOPOP). Metodo smo zaradi razlik v obsegu biodiverzitetnih podatkov v primerjavi z originalno metodo prilagodili ter poskusno izvedli le na biodiverziteti kopenskih, negozdnih okolij Ljubljanskega Barja. Ta območja so na Barju namreč najbolj razširjena in se zanje izvaja največ naravovarstvenih ukrepov. V pilotni akciji smo najprej zbrali podatke o vseh vrstah v Krajinskem parku Ljubljansko barje ter s pomočjo sodelujočih strokovnjakov identificirali, katere vrste so, poleg Natura 2000 kvalifikacijskih vrst, prednostne, torej pomembne za varovanje na Ljubljanskem barju. V nadaljevanju smo, ponovno s pomočjo sodelujočih strokovnjakov, izvedli ekološko karakterizacijo in analizo občutljivosti prednostnih vrst na človekove dejavnosti. Nato smo prednostne vrste združili v “upravljalske cehe” – skupine vrst, ki za ohranjanje potrebujejo podobne naravovarstvene ukrepe. Ugotovili smo, da za večino prednostnih vrst, ki živijo na Barju primanjkuje novejših podatkov, ter natančnejših prostorskih podatkov, redki so sistematični popisi, s tem je povezano tudi slabo poznavanje razširjenosti in ekoloških potreb večine vrst. Zaradi teh razlogov je ekološka karakterizacija večine prednostnih vrst potekala na podlagi najboljše ocene strokovnjaka. V upravljalskih cehih, ki smo jih oblikovali smo identificirali indikatorske vrste – vrste, za katere obstaja največ podatkov o razširjenosti na Ljubljanskem barju, oziroma smo ocenili, da bi lahko služile kot pokazatelj stanja celotnega ceha. V vsakem cehu smo določili tudi krovno vrsto - to je vrsta, za katero se že izvajajo naravovarstveni ukrepi, oziroma bi bilo priporočljivo, da se načrtujejo.

Povzetek: Water can be an important source of plant pathogenic viruses. Usually they are present in low concentrations, but environmental waters still represent a potential pathway for virus transmission. Already over 30 years ago, plant viruses have been shown to be present in environmental waters in considerable amounts (Koenig, 1986). Since then, many questions concerning the origin, survival, and spread of plant viruses by water have been raised, especially in the light of increased irrigation and use of hydroponic systems in agriculture (Mehle and Ravnikar 2012). The majority of the plant pathogenic viruses recovered from environmental waters so far are very stable. They can infect plants via the roots without the aid of a vector and often have a wide host range (Mehle and Ravnikar 2012). The release of such viruses from plants can lead to their diffusion in streams, rivers and lakes, thereby ensuring the long-distance spread of viruses that would otherwise remain restricted to limited areas (Mehle et al., 2014; Mehle and Ravnikar, 2012).

Povzetek: Ljubljansko barje so naravoslovci začeli raziskovati že zelo zgodaj, v 18. stoletju, in zaradi bližine Ljubljane, precej bolj intenzivno kot druge dele Slovenije. Zato je v Sloveniji Ljubljansko barje med območji z najbolj raziskano biodiverziteto. Barje je tudi že več kot 100 let prepoznano kot naravovarstveno pomembno območje (Beuk, 1920). Sprva so bili zakonsko zavarovani le posamezni deli Ljubljanskega barja, leta 2008 pa je bil ustanovljen Krajinski park Ljubljansko barje. Barje je od leta 2004 varovano tudi v okviru Natura 2000 omrežja. Kljub izjemni pestrosti pa naravovarstveni ukrepi naslavljajo predvsem nekaj posameznih krovnih vrst in habitatnih tipov v okviru Nature 2000.

Povzetek: A proposal of a rapid response plan for the Asian hornet (Vespa velutina) was prepared in the LIFE ARTEMIS Project. The Asian hornet is an invasive alien species which is on the priority list of the IAS EU legislation 1143/2014. In the proposal the EWRR system is described for the finding and the rapid response for the asian hornet. First findings of the asian hornet will be submitted to the information system »Invazivke« or to the National Veterinary Institute (NVI). When data is checked, it will be send to the coordinating governmental body - Slovenian Environment Agency (ARSO) within two days. During the rapid response proces, two tactical meetings will be organised. First ARSO will inform The Ministry of the Environment and Spatial Planning (MOP) about the finding, which will send it to the European commission. On the first tactical meeting the coordinator for the rapid response actions will be determined. Institute of the Republic of Slovenia for Nature Conservation (ZRSVN) will prepare a first survey in which the status of the population will be determined. Furthermore, all inform general public, landowners and local communities in the invaded area. Within two days to 14 days after the submission of the survey report, the second tactical meeting will be held. During this meeting the possible eradication actions will be discussed and the tasks will be divided. After that the organisation responsible for the rapid response action will prepare the final plan of eradication. The organisation responsible for the eradication action will take action. Information on the eradication action are written in the report. After that it will be checked whether the eradication was successful. In case this was not, more eradication actions will take place. If it will be successful the area will be monitored for the coming 5 years to be sure that the species is really eradicated. All information will be send to ARSO, who will inform MOP. MOP will inform the European commission and the member states.

Povzetek: The overall increase in maritime transport, coastal urbanization and the foreseen increase in offshore oil and gas extraction pose serious risks of pollution from hazardous substances for several coastal states in the whole Mediterranean, and in particular in the Adriatic - Ionian region. Countries sharing a marine region or sub-region should adopt a common approach to environmental monitoring, good environmental status definition and assessment. In the Adriatic – Ionian marine sub-regions, the level of coherence and consistency of several EU and regional environmental policies, particularly in the assessment of contamination from hazardous substances, needs a common implementation. In the framework of enhancing the capacity to tackle environmental vulnerability and safeguard ecosystem services at transnational scale, the objective of HarmoNIA is twofold: to share best practices to support the harmonized implementation of marine environmental directives in the ADRION regionto strengthen the network of data infrastructures to facilitate access and re-use of marine data among countries bordering the Adriatic – Ionian Seas. Building on the EU initiative EMODnet for the management and supply of fragmented marine data, HarmoNIA will strengthen the existing transnational network of data infrastructures to facilitate access and re-use of marine data among countries bordering the Adriatic – Ionian Seas. The project will improve the coherence, among most countries bordering the Adriatic and Ionian Seas, all Contracting Parties of the Barcelona Convention, of protocols for monitoring and for assessment of contaminants in the marine environment and will facilitate data and information exchange within the region. The outputs will consist in a Transnational network of institutions adopting a joint data management system for contaminants in the marine environment, and in regional strategies to improve harmonization in monitoring and assessment, and to evaluate risk of contaminant dispersion in vulnerable coastal zones from different pollution sources. HarmoNIA outputs will improve the coordination among institutions involved in MSFD and UNEP/MAP protocol implementation, local, regional and national authorities in charge of environmental assessment, management, conservation, as well as research institutions, to tackle problems related to pollution dispersal and risks on the coastal areas of the ADRION region. The transnational approach will be assured by the cooperation among partners from most of the countries bordering the ADRION region, with consolidated experience in marine data acquisition and management and involved in the implementation of marine environmental policies.
