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.

  • Climate campaigners question choice of James Evans for role given past criticism of green energy projects

    The appointment of a Reform UK member of the Senedd Cymru as the chair of a key Welsh environmental committee could “undermine the hard graft of ministerial scrutiny”, a green thinktank has warned.

    James Evans, a former Conservative party MS who defected to Reform UK in January last year, has been appointed chair of the Welsh climate change, environment, sustainability and rural affairs committee.

  • Wakelyns needs £1.2m to save its diverse organic crops and ‘micro’ enterprises including a bakery and honeybee hives

    The aerial view of Wakelyns matches the experience of visiting it at ground level: in a region dominated by prairie fields of industrial agriculture, here lies a vivid green lung of land. Its sounds and sights in summer – the sleepy purr of the turtle dove, the vivid pink flash of a bullfinch – have vanished from most of the British countryside.

    But Wakelyns is not a nature reserve – it is a thriving farm, a “living laboratory” for agroforestry and a hub for innovation and business. It is also under threat, and its owners must raise £1.2m to turn it into a charitable community benefit society.

  • Red warnings issued in Hungary, Poland, Romania and the Balkans, with authorities urging people to stay indoors

    Parts of central, eastern and southern Europe sweltered on Monday as the “heat dome” behind last week’s record-breaking temperatures shifted east, bringing dangerous conditions to a new swathe of the continent.

    Budapest is forecast to exceed 40C on Tuesday, according to models from the European Centre for Medium-Range Weather Forecasts.

  • Energy system operator says sum needed to deliver clean power targets while meeting rising demand is up by 50%

    The cost of rewiring Great Britain’s electricity networks through the 2030s is now 50% higher than before the Labour government came to power, and could reach almost £90bn in the next decade, according to the energy system operator.

    Building new high-voltage transmission lines and infrastructure to connect low-carbon energy to the grid in the 2030s was initially forecast by the energy system operator to cost £58bn.

  • Government hopes for 30% of city’s fleet to be electric by 2030, in move hailed as ‘gamechanger’ on air pollution

    The unruly chaos of Delhi’s roads would be unrecognisable without the rickshaws and scooters that zip through India’s capital in their millions, emitting toxic fumes in their wake. But now, ambitious policies aim to give the city’s most recognisable vehicles an environmental makeover.

    On Monday, Delhi’s government announced plans to eventually ban petrol scooters, motorbikes and autorickshaws in favour of those running on electricity, in an attempt to bring down dangerously high pollution levels in the city by the end of the decade.

  • Outer Hebrides: It’s nearly 100 years since anyone lived on this hostile archipelago, though their ‘village’ remains – as does an astonishing wealth of wildlife

    Dawn on a deep-rolling ocean, and I am about to realise a dream. We’re 35 nautical miles west of the Outer Hebrides, on board the expedition cruise ship M/V Sea Spirit, approaching the archipelago of St Kilda – the most remote outpost of the British Isles, and the UK’s only dual Unesco world heritage site. Impregnable sheer cliffs spike the seascape, rising to 1,400 feet, and we’re in the company of Risso’s dolphins, flights of gannets and hurrying auks.

    We make landing at Hirta, the largest of the four islands at about 2.7 square miles. Above the great storm beach lies a deserted, unnamed “village”, a thin crescent of traditional Hebridean cottages. Nowadays, the only inhabitants are St Kilda wrens (Troglodytes troglodytes hirtensis) – larger and darker than the mainland populations – but each cottage also bears a simple plaque listing the last family to live there.

  • Exclusive: £75m publicity drive will ask people to treat water as precious resource and cut daily use by 28 litres

    The biggest ever campaign to encourage the public to reduce their water use will launch this week, as the UK emerges from record temperatures attributed to the climate crisis.

    The £75m publicity drive, called Let’s Save Water, will advise and encourage people to treat water as a precious resource and has a target for everyone to cut their daily use by 28 litres – or two large buckets – from the current average use of about 140 litres a day.

  • The government’s requisition of a historic green space has ignited a fierce debate about air quality and heat stress in India’s scorching capital

    For decades, the social highlight of winters in Delhi for the “beautiful people” was the polo season. A sprinkling of royalty and diplomats, impeccably groomed women in pearls and chiffon saris, along with wealthy industrialists sporting silk pocket squares used to gather to watch polo players compete under the mild, balmy sun.

    They cheered on handsome players who, once the match was over, had children shrieking in delight as they put on a heart-stopping display of tent-pegging derring-do. Swish champagne lunches and other après-polo celebrations followed.

  • In 1993, she squeezed a $333m settlement from a Californian energy company in a scandal over contaminated water. Three decades later, she has a new target in her sights – and it’s global

    When Erin Brockovich woke to find 30 emails from people from the same town, she realised something was going on. People email Brockovich all the time because of what happened in 1993, when she was instrumental in suing Pacific Gas and Electric Company (PG&E) on behalf of residents of the town of Hinkley, California, whose groundwater had been contaminated. The case resulted in a settlement of $333m – then the largest ever payout for a direct-action lawsuit. When she was immortalised by Julia Roberts in the 2000 film Erin Brockovich, she became the hero we didn’t know we needed, a modern day Joan of Arc. She had won against PG&E with no formal legal training.

    The emails she received a few weeks ago were about datacentres. In April, she put a callout on her website asking for anyone with concerns about one near them to get in touch. Within a month, 3,862 people had replied. Tech companies have needed datacentres to power their technology “for ever”, she says, but the new ones being built to power AI? “This feels like Hinkley on steroids.”

  • Home-grown food may become a niche product for wealthy in our supermarkets as British farmers’ incomes plummet

    For Liz Webster, who farms 647 hectares (1600 acres) in Wiltshire, south west England, the latest impact of Brexit has been particularly brutal. About £400 per animal has been wiped off the price she can get for her beef cattle, a hefty blow at a time when all the inputs – feed, energy, fertiliser – are going through the roof.

    The fall in price, on livestock that typically fetch £2,000 to £3,000 per animal, is the result of a flood of cheaper meat arriving from Australia, the result of one of the new trade deals the government has signed since the UK left the European Union. Prices for beef in the supermarkets have remained broadly the same, but farmers have seen their income plummet.
