Orhideje: Skromne, Nevjerojatne, Očaravajuće!

2023. na Hvaru otkrivena su dva lokaliteta orhideja od strane gostujućih stručnjaka iz Zagreba, koji su pronašli endem Ophrys pharia i Himantoglossum robertianum.

Hrvatske divlje orhideje nisu spektakularne vrste poput onih iz tropskih krajeva. Iako cijenjene među ljubiteljima prirode, prečesto lokalnom stanovništvu prolaze neprimijećeno. Rezultat toga je nemarno uništavanje orhideja i njihovih staništa, posebno kroz ekstenzivnu uporabu herbicida. Ljiljana Borovečki-Voska je vrhunska botaničarka, po profesiji nastavnica. Njezin suprug Berislav Horvatić bio je viši znanstveni suradnik na Institutu za fiziku u Zagrebu, a nakon umirovljenja posvetio je velik dio svog vremena, ali i znanstvene stručnosti proučavanju orhideja zajedno sa svojom suprugom.

Ophrys pharia bila je godinama nedohvatljiva. Berislav i Ljiljana znali su da je Ophrys pharia specifična za Hvar: opisali su je P. Devillers i J. Devillers-Terschuren u časopisu Naturalistes Belges (vol. 85: 233) 2004. godine, a fotografirali su je u blizini sela Vrbanj u središnjem dijelu Hvara u travnju 2007. godine.

Prije 2004. godine, Ophrys pharia bila je opisana kao podvrsta. Kada su 29. travnja 2023. krenuli u potragu za Ophrys phariu na Hvaru, bili su svjesni da će to biti zastrašujući izazov, možda čak i 'nemoguća misija'. Ophrys pharia opisana je na web stranici „Orchids of Britain and Europe“: „Ovo je veoma ugrožena vrsta, za koju se smatralo da je ne samo endem za Hrvatsku, već specifično za otok Hvar, gdje sve agresivnije poljoprivredne metode smanjuju stanište dostupno ovoj vrsti koju sada postaje izuzetno teško pronaći, čak i na njenim nekadašnjim uporištima oko Vrboske, u središnjem dijelu otoka.“

Kada se ugleda sitne orhideje stisnute među ostalim divljim cvijećem, bude sasvim jasno zašto je potrebna stručna makrofotografija kako bi se potvrdilo opažanje rijetkih vrsta!

Još važnije, značajke po kojima se razlikuju pojedine orhideje od drugih, često su vrlo suptilni detalji, što naravno čini orhideje tako fascinantnim i izazovnim biljkama za proučavanje.

Pravi stručnjaci poput Ljiljane (kojih je naravno vrlo malo) godinama strpljivo promatraju orhideje kako bi mogli sa sigurnošću identificirati različite vrste. Ophrys pharia križa se s Ophrys rhodostephane i ti hibridi su izuzetno rijetki.

Ophrys rhodostephane se izrazito razlikuje od Ophrys pharia te obiluje u Dalmaciji, a i na Hvaru. Vrijedan savjet Berislava: „najbolji i najlakši način da ih vidite mnogo je spora vožnja starom cestom između Brusja i Selca - naravno, u pravo doba godine. Neasfaltirana cesta kroz Rovan je također izvrsna.“

Nizozemski stručnjak za orhideje Frank Verhart proučavao je orhideje tijekom nekoliko posjeta Hvaru, no nije ugledao Ophrys phariu, da bi na kraju Berislav i Ljiljana u roku od tri dana pronašli ništa manje od devet primjeraka u okolici Vrbanja! Poput Franka Verharta i drugih botaničara, odmah su podijelili svoja otkrića s hrvatskom bazom podataka Flora Croatica Database. Pronalazak Himantoglossum robertianum (sin. Barlia robertiana) bio je neočekivani bonus, kako prethodno nije bio zabilježen na Hvaru.

Pronalazač je zapravo bio lokalni stanovnik Antun Vranković Bili iz sela Svirče. Iako se vrsta teško pronašla, nakon otkrića, Ljiljana i Berislav odmah su je identificirati. Prvobitno je viđena na području Rovana blizu Svirača. Ljiljana i Berislav su kasnije pronašli još jedan primjerak u masliniku ispod Pitava, zbog čega su zaključili da na otoku ima još primjeraka, iako rijetkih.

Kako bi proslavili da Ophrys pharia nije izumrla na Hvaru, Berislav i Ljiljana su zabilježili svoje povijesno otkriće na šalicama kao trajni suvenir!

  • Dutch government discriminated against Bonaire islanders over climate adaptation, court rules

    Judgment in The Hague orders Netherlands to do more to protect Caribbean people in its territory from impacts of climate crisis

    The Dutch government discriminated against people in one of its most vulnerable territories by not helping them adapt to climate change, a court has found.

    The judgment, announced on Wednesday in The Hague, chastises the Netherlands for treating people on the island of Bonaire, in the Caribbean, differently to inhabitants of the European part of the country and for not doing its fair share to cut national emissions.

  • Smothering, bullying, stabbing: how it feels to be in one of the hottest places on Earth

    Everything felt like it was swelling, and despite my diligent consumption of water and Hydralyte, I couldn’t quite escape the persistent, low-level nausea. Even thinking took longer

    My mother grew up in Warracknabeal, a speck of a town four hours from Melbourne, Australia, in the wide, wheat country of the Wimmera – that part of Victoria where the sky starts to stretch, where you can see weather happening 100 kilometres away.

    Once or twice a year, our family would pack into the rattling old LandCruiser and drive up to visit my grandmother. It can’t always have been blistering weather but my memories of those trips are shot through with summer heat: the peeling paint of my grandmother’s house, the blasted-dry grass of the reserve over the road and its ancient metal monkey bars, so hot they burned your hands. Once, a dust storm blew up while we were there, engulfing the small weatherboard house in howling dirty orange.

  • ‘Like a sea out there’: flooded Somerset residents wonder how water can be managed

    People in south-west mop up after Storm Chandra and prepare for next bout of rain, with major incident declared

    In the early hours, the Wade family’s boxer puppy began barking. Thinking it needed to be let out, they traipsed downstairs and opened the back door – to be greeted not by their neat garden but an expanse of water.

    “It was like a sea out there,” said James Wade. Over the coming hours the water crept into their home on a modern estate in Taunton, forcing James, his wife, Faye, and their three children, six, 11 and 12, out and into emergency accommodation.

  • Swift bricks to be installed on all new buildings in Scotland as MSPs back law

    Rest of UK has resisted calls to make builders install bricks that provide nesting for swifts and other endangered birds

    Swift bricks will be installed in all new buildings in Scotland after the Scottish parliament voted in favour of a law to help endangered cavity-nesting birds.

    The Scottish government and MSPs across the parties backed an amendment by Scottish Green Mark Ruskell to make swift bricks mandatory for all new dwellings “where reasonably practical and appropriate”.

  • ‘My Tesla has become ordinary’: Turkey catches up with EU in electric car sales

    Popularity of EVs in country is part of global trend of emerging markets spurning fossil fuel cars at surprising speeds

    When Berke Astarcıoğlu bought a BMW i3 in 2016, he was one of just 44 people in a country of 80 million to buy a battery electric vehicle (BEV) that year. By the time he bought a Tesla in 2023, BEVs were no longer a complete oddity in Turkey, making up 7% of new car sales.

    Fast-forward two years and electric cars are selling so fast that Turkey has caught up with the EU in its rate of adoption. Its market is now the fourth largest in Europe, behind Germany, the UK and France.

  • Country diary: A woodpecker with a difference – it’s not pecking at wood | Charlie Elder

    West Dartmoor, Devon: It’s quite normal for greater spotteds to start staking out territories in January, less so on a plastic box near my bedroom window

    The electrical junction box, fixed to the top of the roadside telegraph pole, displays a yellow sign that warns “Danger of death”. Not that the bird perched on top seemed the slightest bit concerned – the acoustics are exceptional.

    I was first woken one snowy morning early in January to short bursts of drilling outside the window. While I’m familiar with the territorial sounds of woodpeckers in my village, which lies close to the historic landmark of Brentor church, this noise was different. It had the resonance of someone impatiently tapping their fingers on a desktop, with the speed of a marching band snare-drum roll.

  • Europe’s supermarket shelves packed with ‘misleading’ claims about recycled plastic packaging

    Manufacturers use method that labels plastic as ‘circular’ and climate-friendly, despite being mostly fossil-based

    Europe’s supermarket shelves are packed with brands billing their plastic packaging as sustainable, but often only a fraction of the materials are truly recovered from waste, with the rest made from petroleum.

    Brands using plastic packaging – from Kraft’s Heinz Beanz to Mondelēz’s Philadelphia – use materials made by the plastic manufacturing arm of the oil company Saudi Aramco.

    This article is part of a cross-border investigation, supported by IJ4EU and coordinated by the independent journalist Ludovica Jona, with the media outlets the Guardian, Voxeurop, Mediapart (France), Altreconomia (Italy), Público (Spain), Investigative Reporting Denmark, Deutsche Welle (Germany) and with reporters Lorenzo Sangermano and Lucy Taylor

  • The 16-month battle to reveal the truth about Sydney Water’s poo balls

    After debris balls closed Sydney beaches in October 2024, Guardian Australia reported they could be linked to sewage outfalls. Authorities were less keen to talk

    Last week, after torrential rain in Sydney, fresh poo balls washed up on the beach at Malabar, the closest beach to the problematic Malabar sewage treatment plant.

    Signs were erected on the beach warning people not to touch the “debris balls” or swim. But authorities didn’t let the wider community know. There were no other warnings issued by Sydney Water, the Environment Protection Authority (EPA) or the state government.

  • ‘The land will be left as ashes’: why Patagonia’s wildfires are almost impossible to stop

    Funding cuts, conspiracy theories and ‘powder keg’ pine plantations have seen January’s forest fires tear through Chubut in southern Argentina

    Lucas Chiappe had known for a long time that the fire was coming. For decades, the environmentalist had warned that replacing native trees in the Andes mountain range with highly flammable foreign pine was a recipe for disaster.

    In early January, flames raced down the Pirque hill and edged closer to his home in the Patagonian town of Epuyén, Argentina, where he had lived since the 1970s. Thirty people with six motor pumps fought for hours, hoses stretched for kilometres, but “there was no way”.

  • Ouyen may have hit the highest recorded temperature in Victoria’s history – and some fear it could get even hotter

    As the temperature nears 49C in the Mallee region, residents take refuge in air-conditioned rooms

    In the slanting, late-afternoon summer sun, the fields around the small Australian town of Ouyen – almost 450km north-west of Melbourne – turn the colour of honey. The edges shimmer with silver, that old cruel trick of feigning water where it hasn’t rained for weeks.

    Summer is always hot out here in the sparse, flat Mallee, but this year is shaping up to be particularly harsh. Just two weeks ago, on Thursday 8 January, Ouyen got to 47.5C. On Monday it reached 44.3C.
