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!

Izuzetno smo zahvalni Berislavu Horvatiću i Ljiljani Borovečki-Voska što su s nama podijelili neprocjenjive informacije o svom uspješnom terenskom putovanju na Hvar 2023. godine, kao i na dopuštenju da koristimo njihove tekstove i fotografije. Njihova predanost je od iznimne pomoći u kampanji podizanja svijesti o detaljima predivnih prirodnih resursa Hrvatske, kako bi ih očuvali i njegovali za buduće generacije.

  • ‘Fast-track’ regulation could expose Britons to harmful chemicals, say campaigners

    Exclusive: Fighting Dirty taking legal action against government over proposal it says could import weaker standards

    An environmental campaign group is taking legal action against the government over proposals that it claims could fast-track chemical hazard classifications from other countries with lower standards into UK law.

    Fighting Dirty claims proposals to change the classification and labelling of potentially hazardous chemicals could result in the UK weakening standards on cancer-causing substances.

  • Trees may store less planet-heating carbon than hoped, study suggests

    Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

    Trees may not be able to store as much planet-heating carbon as hoped, a study suggests, with researchers finding photosynthesis does not always lead to wood growth.

    Scientists studied 137 sites across the US and found trees stopped growing months before the point in the year at which photosynthesis stopped.

  • Antarctica’s west coast missing an area of sea ice the size of France as temperatures peak 20C above average

    ExclusiveA vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

    Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.

    One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsula last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

  • Tropical heron spotted in UK for first time as more exotic birds arrive to thrill birdwatchers

    Appearance of a western reef heron in north Wales is unlikely to be the last, as heating temperatures mean species can survive Britain’s winter, say experts

    It is a tropical bird typically encountered between west Africa and India, but last week a western reef heron arrived in north Wales in what is believed to be the first ever sighting in the UK.

    The heron was first spotted in Foryd Bay at the weekend before flying to nearby Caernarfon harbour where it fed among the boats.

  • Country diary: It’s a painted lady summer, the stuff of lepidopterists’ legend | Phil Gates

    Wolsingham, Weardale: These stunning butterflies are here in incredible numbers this year, yet what’s most remarkable is their multigenerational migration

    There’s a painted lady basking on the footpath. Her orange, black-tipped, white-spotted wings, a little worn after her long journey, blend with shadows and sun-flecks on heatwave-baked mud, so she’s almost under our feet before she takes flight. And here’s another, nectaring on a dandelion; and another; then several more. I can’t recall ever seeing so many so early in the year.

    Waiting for the arrival of these migrant butterflies is akin to anticipating the first swallow. Tantalising mid-April sightings from Wales and Cumbria were reported on social media, but we waited until mid-May before finding our first in Weardale.

  • Emergency hospital admissions fell after introduction of London’s T-charge and Ulez, study suggests

    Imperial College scientists analysed health records before and after introduction of air pollution reduction zones

    Low emission and clean air zones attract controversy whenever they are proposed, but there is growing evidence that they work in improving air quality. The Bradford zone was followed by a reduction of about 25% in GP visits for heart and breathing problems and survey data shows that the central London zone was followed by a reduction in the likelihood of a person taking sick leave.

    Now analysis of health records has found emergency admissions to hospital reduced after the introduction of the T-charge and ultra-low emissions zone (Ulez) in central London.

  • Freedivers, leftover cables and bits of clay: Cuba gets inventive to save its pristine reefs amid US blockade

    With limited resources and sanctions tightening, conservationists are forced to find new ways to protect the coral reefs of Ciénaga de Zapata national park

    At 8am, scuba divers gather to collect plastic and drinks cans from the sea at Cuba’s Ciénaga de Zapata national park. Amid a power crisis that has virtually paralysed the country’s economy, they use an electric trailer to move to a designated spot. In only a few hours, they have collected five sacks of cans and waste.

    Lack of environmental awareness, invasive species and the climate crisis have long threatened the island’s pristine marine ecosystem but as US sanctions and economic scarcity take their toll on the country, scientists and community conservationists are working with even scarcer resources to protect a vital ecosystem for the Caribbean and the world.

  • ‘It’s massive destruction’: outcry in Texas over waivers to allow border wall in Big Bend national park

    Despite plunging border crossings, the Trump administration is circumventing laws to expedite building in a vast, pristine wilderness

    The Trump administration has waived a slew of environmental and historical preservation laws that would allow it to build a towering border wall that cuts through Big Bend national park, a vast protected wilderness in south Texas.

    Congress poured a whopping $46.5bn for border wall construction into the “Big, Beautiful” bill last year, supercharging Donald Trump’s ambition to wall off the southern border with Mexico. The longest unwalled stretches lie along a roughly 500-mile (800km) section of west Texas that Customs and Border Protection calls the “Big Bend sector”.

  • ‘This is what I was born for’: the drought-ridden Colombian town that took on Coca-Cola Femsa – and won

    While La Calera faced severe water rationing, local springs were being drained by the drinks giant’s franchise. So the residents fought back

    When a severe drought struck La Calera near Bogotá, many of its residents lost their water for drinking, cooking and farming and faced up to 15 days of strict water rationing each month. Yet the area is home to Chingaza reservoir, which supplies about 70% of the drinking water for Colombia’s capital.

    As the drought stretched from April 2024 to April last year, people began to look more closely at how their water was being managed.
