Orchid enthusiast Frank Verhart continued his researches into European orchids during 2016. He found much of interest on the Pelješac peninsula.

Frank Verhart from the Netherlands has lifelong experience looking out for orchids, and his expertise increases year on year. In 2015 he explored the Dalmatian islands of Hvar and Brač as the guest of Eco Hvar, and introduced many to the magic of the often tiny treasures to be found in woodlands, fields, gardens and roadsides. He was able to show why it is so important to look after these protected plants, as they all too easily get overlooked when individuals and local authorities spray areas with herbicides, and as a result of thoughtless fly-tipping in the countryside. Mapping where the orchids are to be found plays a key role in their protection. Frank logs his orchid findings with care, resulting in detailed maps for the records. In his identifications and classifications, he uses the taxonomy from the standard work by the Belgian expert Pierre Delforge, 'Orchids of Europe, North Africa and the Middle East', published by Christopher Helm Publishers, 2006.
Over several years, Frank has generously been sharing his detailed findings with Prof.dr.sc. Toni Nikolić at the Department of Botany in the Biology Division of Zagreb's Science University, who is responsible for compiling the full listing of Croatia's plants, the Flora Croatica Database.
In 2016, Frank visited France and Croatia, by way of Slovenia. As he reports: "all still and as usual by hitch-hiking. On the way [to Croatia] I have visited and stayed overnight at Miran Ipavec's Autostoparski Muzej (Hitch-hiking Museum) in Bled, Slovenia. Miran is maybe the most experienced hitch-hiker, distance wise, in Slovenia.. I’ve again been able to do some very cool observations, especially Orchis ustulata and Cephalanthera damasonium (Burnt orchid and White helleborine) as they have never been reported from Pelješac before, and I am fairly confident indeed, that there are no official reports of those. The latter has recently been found by Croatian botanists for the first time on Mljet 2012 and Korčula 2013, I think this is quite remarkable..."
The Orchis ustulata (neotinea ustulata, burnt orchid, burnt-tip orchid) is fairly common across Europe, to which it is native, but is considered endangered in the United Kingdom, according to the Kew Royal Botanic Gardens. That said, Kew reports that there has been a significant decline in central Europe "due to habitat destruction as a result of building, quarrying and, in particular, more intense agricultural practices. Burnt-tip orchids can only survive in unfertilised, unploughed grassland due to their protracted underground growth period. In addition, where grazing is discontinued burnt-tip orchid is liable to decline because its small size means it cannot survive in long grass."
Besides the rare findings on Pelješac, Frank observed many more familiar orchids. However, a couple appeared in unusual colours, notably the orchis morio (pictured above), and the orchis italica (below).

New study reveals negative impact of climate change, human activity, acidification and deoxygenation on ocean and its creatures
The deep ocean and the creatures that live there are facing a desperate future due to food shortages and changing temperatures, according to research exploring the impact of climate change and human activity on the world’s seas.
The deep ocean plays a critical role in sustaining our fishing and removing carbon dioxide from the atmosphere, as well as being home to a huge array of creatures. But the new study reveals that food supplies at the seafloor in the deepest regions of the ocean could fall by up to 55% by 2100, starving the animals and microbes that exist there, while changes in temperature, pH and oxygen levels are also predicted to take their toll on fragile ecosystems.
Macquarie insists it is committed to renewable energy – but critics say it could invest in fossil fuels if its bid succeeds
The Australian investment bank on the verge of buying the UK’s publicly owned Green Investment Bank has launched a Westminster charm offensive after parliamentarians of all parties told Theresa May to halt the £2bn sale.
Green party co-leader Caroline Lucas, the Lib Dems’ Vince Cable and former Tory minister Lord Barker last month warned a sale to Macquarie would put the bank’s green purpose at risk and its most valuable assets, such as large windfarms, could be sold off.
Researchers will have to deal with attacks from a range of powerful foes in the coming years – and for many, it has already started
A little less than seven years ago, the climate scientist Michael Mann ambled into his office at Penn State University with a wedge of mail tucked under his arm. As he tore into one of the envelopes, which was hand-addressed to him, white powder tumbled from the folds of the letter. Mann recoiled from the grainy plume and rushed to the bathroom to scrub his hands.
Fortunately for Mann, the FBI confirmed the powder was cornstarch rather than anthrax. It was perhaps the nadir of the vituperation hurled at Mann by often anonymous critics who accuse him and others of fabricating or exaggerating the dangers of climate change.
Environmentalists hail ‘landmark moment’ as world’s biggest soft drinks company agrees to set up pilot scheme in Scotland
Coca-Cola has announced it supports testing a deposit return service for drinks cans and bottles, in a major coup for environment and anti-waste campaigners.
Executives told an event in Edinburgh on Tuesday evening they agreed with campaigners who were pressing the Scottish government to set up a bottle-return pilot scheme to cut waste and pollution and boost recycling.
Donald Trump is a deal maker, and there’s a great deal to be made on climate change
A month into his presidency, Donald Trump already has a minus-8 job approval rating (43% approve, 51% disapprove). Congress has a minus-50 approval rating, and the Republican Party has a minus-14 favorability rating. All are facing widespread protests, marches, and public resistance. Hundreds of concerned constituents have been showing up to town hall events held by Republican Congressmen, like this one with Tom McClintock (R-CA):

A sacred Tibetan lake, a crack in the Antarctic ice shelf and deforestation in Cambodia are among images captured by Nasa and the ESA this month
Yamzho Yumco (Sacred Swan) Lake is one of the three largest sacred lakes in Tibet. It is surrounded by snow-capped mountains and is highly crenellated with many bays and inlets. The lake is home to the Samding monastery which is headed by a female reincarnation, Samding Dorje Phagmo. The image covers an area of 49.8km by 60km. Aster images map and monitor the changing surface of our planet, such as glacial advances and retreats; potentially active volcanoes; crop stress; cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.
As renewable energy projects are rolled out in cities around the world, we spoke to companies and organisations working in the sector to find out what’s happening and what to expect. Here’s what they said.
