Can anyone help with information about dragonflies on Hvar?

Dragonfly Dragonfly Steve Jones

Steve from Dol has sent us the following query by email on 23rd September 2016:

'Do you know much about dragonflies on the Island?

Over the Summer I have seen several and I know Norman nearby has also seen similar.

While I know a few of the more obvious ones I am puzzled, one thing I do know is that they like water in which to lay. The dragonfly life cycle is for the most part spent underwater and they only emerge as what we see towards the end of their life and to mate.

I am puzzled as to where they can possibly lay eggs, I only know one source of water down near the airfield and I don’t believe from there they would travel up to Dol. I often think they could be laying in the numerous wells/water storage places in the field but most are covered and I don’t know how they would emerge. One species described to me was the Golden Ringed Dragonfly and this as I read likes fast flowing water so I even more at a loss.

I was down near the airfield yesterday and several of just two species that I could tell were flying the one species tended to be flying joined to his mate, there were several of these

Didn’t know whether or not you can shed any light on this for me? I know of someone in the UK who specialises in Dragonflies, I may email him and see what comes of it.'

Eco Hvar's reply, 23rd September 2016:

Yes, actually there are many more sources of water than you'd think, off the beaten tracks, but also in the fields.

A lot of the enclosed wells have open basin on top,which can be home to all sorts of insects, including water snakes. Unless the fields around the wells have been doused in herbicide of course. There was a superb little water snake in the open part of the well by my field one year. It would curl itself round and round very lazily, right up to the time the basin went dry. I was afraid 'my' snake had died, lying there quietly, but it then discreetly disappeared, re-appearing a cuple of times in the grass above the well, presumably looking forward to the winter rains which would replenish its basking place. 

Talking about herbicide, did you see that the sale of Cidokor/Roundup is to be banned from October 1st, together with 12 other glyphosate-based herbicides? Good as far as it goes, but it still leaves 12 other glyphosate herbicides on the market!

We''ll look forward to hearing the results of your dragonfly investigations. A good place to see them is in the environs of Humac, where there are some lovely natural pools where the horses and some hunting dogs drink and butterflies abound, as there are no poisoned fields in the vicinity.

  • Spike in fossil fuel use a result of global gas crisis triggered by Russia’s invasion of Ukraine

    The world’s coal use is expected to reach a fresh high of 8.7bn tonnes this year, and remain at near-record levels for years as a result of a global gas crisis triggered by Russia’s invasion of Ukraine.

    There has been record production and trade of coal and power generation from coal since Russia’s full-scale invasion of Ukraine inflated global gas market prices, according to the International Energy Agency (IEA).

  • Climate-vulnerable pair add weight to proposed treaty seeking transition from coal, oil and gas in equitable way

    Pakistan and the Bahamas have joined a growing bloc of climate-vulnerable countries seeking to broker a global pact to phase out fossil fuels in an equitable way, the Guardian can reveal.

    The Bahamas is the 15th nation to fully endorse the proposed fossil-fuel non-proliferation treaty, which would provide a binding global roadmap to explicitly halt expansion of coal, oil and gas in a fair way – with wealthy nations responsible for the highest emissions transitioning first and fastest.

  • Trade can help protect species – and real skins are often more sustainable than synthetic alternatives, say conservationists

    Conservation experts have criticised a decision by London fashion week to ban exotic animal skins from its 2025 shows as “ridiculous”, warning that it is ill-informed and could harm the protection of many snakes, crocodiles and reptile species.

    Last month, the British Fashion Council’s deputy director for policy and engagement, David Leigh-Pemberton, told parliament that next year’s fashion shows would prohibit the use of skins from alligators, snakes and other animals. In a statement, the council said the ban was part of a wider range of standards to promote sustainable practices in the fashion industry.

  • Southill, Bedfordshire: On a ringing session of seed-eating farmland birds, I see up close the subtle beauty of the yellowhammer

    We’ve just released a second blitz of tits, when we notice that the mist net along the field edge has caught a sunbeam. The cold orange light that spilt over the horizon at dawn and pooled above the fields is long gone; the teasel, knapweed and bristly oxtongue seedheads are no longer haloed with hoarfrost. Instead, they’re drawing ground-feeding birds down to forage among the wild grasses and flowers.

    The fallow fields around us are part of an ambitious project to restore ecosystems across more than 1,500 acres of the Southill Estate. The plan includes creating new ponds, allowing land to revert to native scrub, and planting woodland for coppicing. Today’s visit is one of a series of winter ringing sessions to monitor the birds flocking to the fields. I’ve tagged along with my dad (a licensed ringer) and Suzy (a trainee). Their primary aim is to record seed-eating farmland species, many of which – such as greenfinch and corn bunting – are on the UK red list. And we’re in luck. Linnets lurk in the scrub and tinklings of goldfinches pass overhead.

  • Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear

    They are easy to install, and knock chunks off electricity bills. It may not be Romeo and Juliet, but Spain’s balcony scene is heating up as the country embraces what has hitherto been a mainly German love affair with DIY plug-in solar panels.

    Panels have already been installed on about 1.5m German balconies, where they are so popular the term Balkonkraftwerk (balcony power plant) has been coined.

  • In 2019, scientists published a climate-friendly food plan. I’ve long wondered: could it work for most Americans?

    As a fossil fuels and climate reporter, most of my journalism focuses on the need to radically overhaul the energy system. But the food sector also needs a makeover, as it creates between a quarter and a third of all greenhouse gas emissions.

    When scientists came up with a new climate-friendly food plan in 2019 and published their findings in the medical journal the Lancet, I read with interest. The guidelines called for more vegetables, legumes and whole grains, which seemed doable to me. The authors even allowed for meat and dairy consumption, albeit in small quantities. Both are major drivers of the climate crisis: the United Nations estimates that meat and dairy produce more than 11% of all global greenhouse gas emissions, and some experts put the figure at up to 19.6%.

  • Restoring age-old land rights has enabled 300 villagers to build a profitable business and halt the exodus to the city

    It’s late morning and the sound of axes clacking against wood echoes through Pachgaon’s bamboo forest in the central Indian state of Maharashtra. A huge depot, larger than a cricket stadium,is full of bamboo branches, stacked neatly by size in different sections. Nearby is a small, windowless office painted in the colours of the forest – a record-keeper of Pachgaon’s turnaround from abject poverty to relative wealth in just over a decade.

    Pachgaon’s rags-to-riches story follows the implementation of two longstanding Indian laws that restored to the local adivasi (tribal) community its traditional ownership rights over the forest, which they lost to rulers and colonisers several generations ago.

  • By rejecting traditional grazing and maintaining trees and wildlife habitats alongside pasture, farmers are turning their land carbon positive. But will it be enough?

    On a humid dawn in Colombia’s livestock capital, Michael Robbin rides across one of his farm’s pastures, where tall green stalks brush his horse’s belly. When he bought the land outside Montería in 2020 he divided it into 125 smaller fields. His neighbours called him crazy at first.

    “That’s not how it’s done in this area,” he acknowledges. “Everybody was looking at me like I was from outer space.”

    MARA NORTH CONSERVANCY, Kenya — Under a fading sun, Kenya’s Maasai Mara came alive.

    A land cruiser passed through a wide-open savanna, where a pride of lions stirred from a day-long slumber. Steps away, elephants treaded single-file through tall grass, while giraffes peered from a thicket of acacia trees. But just over a ridge was a sight most safari-goers might not expect — dozens of herders guiding cattle into an enclosure for the night. The herders were swathed in vibrant red blankets carrying long wooden staffs, their beaded jewelry jingling softly.

    Maasai Mara is the northern reach of a massive, connected ecosystem beginning in neighboring Tanzania’s world-famous Serengeti. Unlike most parks, typically managed by local or national governments, these lands are protected under a wildlife conservancy — a unique type of protected area managed directly by the Indigenous People who own the land.

    Conservancies allow the people that live near national parks or reserves to combine their properties into large, protected areas for wildlife. These landowners can then earn income by leasing that land for safaris, lodges and other tourism activities. Communities in Maasai Mara have created 24 conservancies, protecting a total of 180,000 hectares (450,000 acres) — effectively doubling the total area of habitat for wildlife in the region, beyond the boundaries of nearby Maasai Mara National Reserve.

    “It's significant income for families that have few other economic opportunities — around US$ 350 a month on average for a family. In Kenya, that's the equivalent of a graduate salary coming out of university,” said Elijah Toirai, Conservation International’s community engagement lead in Africa.

    But elsewhere in Africa, the conservancy model has remained far out of reach.

    “Conservancies have the potential to lift pastoral communities out of poverty in many African landscapes. But starting a conservancy requires significant funding — money they simply don't have,” said Bjorn Stauch, senior vice president of Conservation International’s nature finance division.

    Upfront costs can include mapping out land boundaries, removing fences that prevent the movement of wildlife, eradicating invasive species that crowd out native grasses, creating firebreaks to prevent runaway wildfires, as well building infrastructure like roads and drainage ditches that are essential for successful safaris. Once established, conservancies need to develop management plans that guide their specified land use for the future.

    Conservation International wanted to find a way for local communities to start conservancies and strengthen existing ones. Over the next three years, the organization aims to invest millions of dollars in new and emerging conservancies across Southern and East Africa. The funds will be provided as loans, which the conservancies will repay through tourism leases. This financing will jumpstart new conservancies and reinforce those already in place. The approach builds on an initial model that has proven highly effective and popular with local communities.

    “We’re always looking for creative new ways to pay for conservation efforts that last,” Stauch said. “This is really a durable financing mechanism that puts money directly in the pockets of those who live closest to nature — giving them a leg up. And it’s been proven to work in the direst circumstances imaginable.”

    Creativity from crisis

    In 2020, the entire conservancy model almost collapsed overnight.

    “No one thought that the world could stop in 24 hours,” said Kelvin Alie, senior vice president and acting Africa lead for Conservation International. “But then came the pandemic, and suddenly Kenya is shutting its doors on March 23, 2020. And in the Mara, this steady and very well-rounded model based on safari tourism came to a screeching halt.”

    Tourism operators, who generate the income to pay landowners' leases, found themselves without revenue. Communities faced a difficult choice: replace the lost income by fencing off their lands for grazing, converting it to agriculture, or selling to developers — each of which would have had drastic consequences for the Maasai Mara’s people and wildlife.

    “But then the nature finance team at Conservation International — these crazy guys — came up with a wild idea,” Alie said. “In just six months they put this entirely new funding model together: loaning money at an affordable rate to the conservancies so that they can continue to pay staff and wildlife rangers.”

    Conservation International and the Maasai Mara Wildlife Conservancies Association launched the African Conservancies Fund — a rescue package to offset lost revenues for approximately 3,000 people in the area who rely on tourism income. Between December 2020 and December 2022, the fund provided more than US$ 2 million in affordable loans to four conservancies managing 70,000 hectares (170,000 acres).

    The loans enabled families in the Maasai Mara to continue receiving income from their lands to pay for health care, home repairs, school fees and more. And because tourism revenues — not government funding — support wildlife protection in conservancies, this replacement funding ensured wildlife patrols continued normally, with rangers working full time.

    Born out of this emergency, we discovered a new way to do conservation.

    Elijah Toirai

    “The catastrophe of COVID-19 was total for us,” said Benard Leperes, a landowner with Mara North Conservancy and a conservation expert at Maasai Mara Wildlife Conservancies Association. “Without Conservation International and the fund, this landscape would have not been secured; the conservancies would have disintegrated as people were forced to sell their land to convert it to agriculture.”

    But it was communities themselves that proved the model might be replicable after the pandemic ended.

    “The conservancies had until 2023 before the first payment was due,” Toirai said. “But as soon as tourism resumed in mid-2021, the communities started paying back the loans. Today, the loans are being repaid way ahead of schedule.”

    “Born out of this emergency, we discovered a new way to do conservation.”

    A new era for conservation

    The high plateaus overlooking the Maasai Mara are home to the very last giant pangolins in Kenya.

    These mammals, armored with distinctive interlocking scales, are highly endangered because of illegal wildlife trade. In Kenya, threats from poaching, deforestation and electric fences meant to deter elephants from crops have caused the species to nearly disappear. Today, scientists believe there could be as few as 30 giant pangolins left in Kenya.

    Conservancies could be crucial to bringing them back. Conservation International has identified opportunities to provide transformative funding for conservancies in this area — a sprawling grassland northwest of Maasai Mara that is the very last pangolin stronghold in the country. The fund will help communities better protect an existing 10,000-hectare (25,000-acre) conservancy and bring an additional 5,000 hectares under protection. It provides a safety net, ensuring a steady income for the communities as the work of expanding the conservancy begins. With a stable income, communities can start work to restore the savanna and remove electric fences that have killed pangolins. And as wildlife move back into the ecosystem, the grasslands will begin to recover.

    In addition to expanding conservancies around Maasai Mara, Conservation International has identified other critical ecosystems where community conservancies can help lift people out poverty, while providing new habitats for wildlife. Conservation International has ambitious plans to restore a critical and highly degraded savanna between Amboseli and Tsavo National Parks in southern Kenya, as well as a swath of savanna outside Kruger National Park in South Africa.

    Many of the new and emerging community conservancies have been carefully chosen as key wildlife corridors that would be threatened by overgrazing livestock.

    When the first Maasai Mara conservancies were established in 2009, cattle grazing was prohibited within their boundaries. When poorly managed, cattle can wear grasses down to their roots, triggering topsoil erosion and the loss of nutrients, microbes and biodiversity vital for soil health. It was also believed that tourists would be put off by the sight of livestock mingling with wildlife.

    Cattle are closely monitored in the Maasai Mara to prevent overgrazing.

    However, over the years, landowners objected, lamenting the loss of cultural ties to cattle and herding. “That was when we changed tactics,” said Raphael Kereto, the grazing manager for Mara North Conservancy.

    Beginning in 2018, Mara North and other conservancies in the region started adopting livestock grazing practices to restore the savanna. Landowners agreed to periodically move livestock between different pastures, allowing grazed lands to recover and regrow,  mimicking the traditional methods pastoralists have used on these lands for hundreds, if not thousands, of years.

    “Initially, there was a worry that maybe herbivores and other wildlife will run away from cattle,” said Kereto. “But we have seen the exact opposite — the wildlife all follow where cattle are grazing. This is because we have a lot of grass, and all the animals follow where there is a lot of grass. We even saw a cheetah with a cub that spent all her time rotating with wildlife.”

    “It's amazing — when we move cattle, the cheetah comes with it.”

    The loans issued by the fund — now called the African Conservancies Facility — will enhance rotational grazing systems, which are practiced differently in each conservancy, by incorporating best practices and lessons from the organization’s Herding for Health program in southern Africa.

    For landowners like Dickson Kaelo, who was among the pioneers to propose the conservancy model in Kenya, the return of cattle to the ecosystem has restored a natural order.

    “I always wanted to understand how it was that there was so much more wildlife in the conservancies than in Maasai Mara National Reserve,” said Kaelo, who heads the Kenya Wildlife Conservancy Association, based in Nairobi.

    “I went to the communities and asked them this question. They told me savannas were created by elephants, fire and Maasai and cattle, and excluding any one of those is not good for the health of the system. So, I believe in the conservancies — I know that every single month, people go to the bank and they have some money, they haven't lost their culture because they still are cattle keepers, and the land is much healthier, with more grass, more wildlife, and the trees have not been cut.

    “For me, it’s something really beautiful.”
