A Malaysian tree climber, Jami, shares their extraordinary experience of climbing the world's tallest tropical tree, a 100.8-meter yellow meranti in Borneo's rainforest. Growing up around logging camps, Jami developed a passion for conservation while working with the South East Asia Rainforest Research Partnership in the Danum Valley. Jami's journey into tree climbing began when they saw colleagues measuring tree heights and monitoring wildlife from the canopy. Despite an initial fear of heights, Jami was determined to challenge themselves and contribute to conservation research. The climb, which took over two hours, was a slow and meticulous process. Jami had to carefully assess the tree's branches for strength and watch out for potential dangers like snakes, scorpions, and insects. At one point, Jami was attacked by bees and received over 100 stings. Upon reaching 70 meters, Jami's fear subsided, and they began to appreciate the wider landscape. The view from the top was breathtaking, with the rainforest's canopy resembling the sea and clouds peeking over the forest. Jami measured the tree's final height using a pole and confirmed it to be 100.8 meters tall. Jami emphasizes the importance of preserving the world's forests, stating that every tree tells a unique story about our history. For Jami, the experience of climbing the tallest tropical tree was a reminder of the serenity and beauty of nature, and they hope to inspire others to join conservation efforts.

The arrival of spring brings a cherished Easter tradition for many – a pilgrimage to witness the breathtaking bloom of pasqueflowers in the Chiltern Hills. Every year, as the days lengthen and the landscape awakens, enthusiasts make their way to the sunny slopes of Church Hill, where approximately 60,000 of these delicate flowers emerge.The pasqueflower, named from the Middle English 'paschal' meaning 'of Easter', is a rare sight in today's landscape. Its felty flower buds, surrounded by plumes of white-haired bracts, push through the shallow soil, and the undersides of the petal-like sepals feel warm and soft to the touch. As the flowers unfurl, they reveal hosts of golden anthers, creating a stunning mosaic of green, white, and violet across the hillside.However, the pasqueflower's presence is a conservation success story. Once found in 130 locations in 1750, changes in grassland management and ploughing have reduced its numbers drastically, leaving only 18 sites, with five locations containing 99.3% of the country's remaining plants. Church Hill, now a local nature reserve and site of special scientific interest, holds over a third of the UK's pasqueflowers, a plant classified as 'vulnerable' on the Great Britain Red List.The sight of these flowers is not just a natural wonder but also a testament to conservation efforts. The hope is that this precious site will continue to protect Hertfordshire's county flower for generations to come, allowing sundry folk to enjoy the beauty of nature rather than commemorating the past.

The UK's swift population has been declining at an alarming rate, with a 68% decline recorded between 1995 and 2023. This has led to a significant decrease in the number of swifts in the country's skies, with many conservationists working to protect these birds.Swifts are known for their impressive endurance, flying 14,000 miles annually from sub-Saharan Africa to nest in the UK and back again. They are a beloved species, providing a heart-soaring display of beauty with their long swooping wings and pale throats.Why do they need to be saved?The reasons for the decline are complex, but it's likely that the loss of nesting sites is a contributing factor. Changes in building management and renovation practices over the past 100 years have made it harder for swifts to find the holes and nooks they need to nest. Additionally, insect populations are believed to have declined, which can impact the swifts' food supply.How can you help?There are several ways to help protect swifts, including:Become a nest detective: Use the RSPB Swift Mapper app and website to record sightings of nesting swifts and help conservation groups focus their efforts.Install swift bricks: Fit small structures into building walls to provide a forever nest for swifts.Install swift boxes: Build or purchase inexpensive nest boxes and install them under eaves at a minimum of five meters high.Protect insects: Plant flowers, nectar, fruit, and berries to support insect life and bird life.Get involved in local swift conservation: Contact a swift group or local RSPB group to get involved in conservation efforts.By taking these steps, individuals can help make a difference in the conservation of swifts and protect these amazing birds for future generations.

The UK's food self-sufficiency has been on a downward trend, falling from 78% in 1984 to 62% in 2024. This decline is largely attributed to the loss of farmland to non-farming uses such as buildings, roads, and conservation schemes. To address this issue, experts suggest that increasing food production on UK farms is crucial. However, promoting a more plant-based diet, while beneficial for health and environmental reasons, may not necessarily use fewer resources than traditional livestock farming. Beef cattle and sheep are often raised on extensively managed grasslands and mountain heath, which account for 38% of the UK's land area. This land receives minimal fertilizer and chemicals, and the animals are primarily fed on grazed and conserved grass. To improve food security, individuals can make a difference by making informed choices when shopping and cooking. Opting for local, organic, animal-friendly, and fairtrade products can contribute to a more sustainable food system. Additionally, growing one's own food, using seasonal products, and supporting local ventures can also help. Experts emphasize that it is essential to utilize the UK's existing food production resources efficiently, rather than wasting them on unsustainable practices. By adopting a more sustainable approach to food production and consumption, the UK can work towards a more secure food future.

An active oil spill in the Gulf of Mexico has spread across seven nature reserves, covering an area of more than 600km (373 miles). The spill, which originated from an unidentified vessel and two natural sources, has had devastating effects on local wildlife and ecosystems.Mexican authorities have confirmed that the spill has killed sea turtles, a manatee, and various fish species. Additionally, reports from communities in the area indicate that approximately 17 reefs have been damaged. Oceana, an international organization focused on ocean conservation, highlighted these findings, emphasizing the severity of the environmental impact.The sources of the spill have been identified as a vessel docked off the coast of Coatzacoalcos in Veracruz, a geological site known as a 'chapopotera' 8km from the Coatzacoalcos port, and another natural leak site in the Bay of Campeche. The Navy Secretary, Admiral Raymundo Morales, confirmed that the spill point remains active, with a greater flow of contaminants observed in the last month.Environmental organizations, including Greenpeace Mexico, have denounced the alleged inaction by state authorities, calling for faster communication and mitigation of the damage. The Gulf of Mexico has been treated as a 'sacrifice zone for the oil industry,' according to Greenpeace, which urged the government to design and implement effective protocols to prevent and respond to environmental risks associated with oil activities.At least six species, including sea turtles, birds, and fish, have been contaminated so far. The incident has also raised concerns about the potential impact on oysters in the connected Mecoacan lagoon and the fishermen harvesting them, particularly after an explosion occurred at the Olmeca refinery on March 17, resulting in five fatalities.

Malaysian Prime Minister Anwar Ibrahim revealed in a televised address that Iran's President Masoud Pezeshkian has allowed Malaysian vessels to pass through the Strait of Hormuz with 'early clearance'. This development comes as the global energy market faces significant disruptions due to the ongoing conflict between Iran, the United States, and Israel.Anwar expressed gratitude to Pezeshkian for the clearance, which will enable Malaysian oil tankers and their crews to continue their journey home. While he did not specify the number of vessels cleared or the conditions for safe passage, he emphasized that Malaysia is working to secure the release of its ships and personnel.The Strait of Hormuz is a vital waterway, facilitating about one-fifth of global oil and liquefied natural gas (LNG) supplies. Iran has claimed the right to control the strait and has been responsible for several attacks on commercial vessels in the region. Despite Iran's assertion that the strait is open to non-aligned ships, there have been reports of Iranian authorities demanding tolls of up to $2 million for safe passage.Malaysia, a net energy exporter and one of the world's top LNG suppliers, imports nearly 70% of its crude oil from the Gulf region. Anwar noted that while Malaysia is better positioned than other nations due to its state-run oil and gas company Petronas, the country will still face impacts from the energy supply disruptions. To mitigate these effects, the government plans to implement fuel conservation measures, including reducing subsidized petrol quotas and encouraging civil servants to work from home.Anwar warned that food, fertilizer, and oil prices are likely to rise due to the disruptions. He emphasized that Malaysia is taking steps to address these challenges, adding that some countries are experiencing far worse impacts than Malaysia.

Oil prices have climbed higher amid fading hopes of deescalation in the Iran war following Tehran’s denial that talks with the United States are under way.Futures for Brent crude, the international benchmark, rose nearly 2 percent on Thursday to top $104 per barrel after Tehran dismissed reports of direct negotiations with US President Donald Trump’s administration.The rise comes after oil prices eased on Wednesday following reports that Trump had shared a 15-point plan for ending the war with Iran.Iranian Foreign Minister Abbas Araghchi said in an interview with state media aired on Wednesday that Tehran was not engaged in direct talks with Washington and has “no intention of negotiating for now”.White House Press Secretary Karoline Leavitt warned on Wednesday that Iran would be “hit harder” than ever before if Tehran did not accept military defeat.Iran’s effective closure of the Strait of Hormuz, a conduit for one-fifth of global oil supplies, and its attacks on energy facilities across the Middle East have prompted a surge in energy prices worldwide.Oil prices are up more than 40 percent compared with before the US and Israel launched strikes on Iran on February 28, prompting numerous countries to implement fuel rationing and other energy conservation measures.Market-watchers say prices are likely to rise further until shipping is free to traverse the strait, despite efforts by countries to bolster supply by tapping emergency stockpiles in coordination with the International Energy Agency.While Tehran has repeatedly claimed that the strait is open to ships that are not aligned with its enemies, daily transits have all but collapsed since the start of the conflict.Four vessels were tracked transiting the waterway via their automatic identification systems on Tuesday, down from an average of 120 daily transits before the conflict, according to maritime intelligence firm Windward.

In a groundbreaking experiment conducted in Colorado's Rocky Mountain meadows, scientists heated a patch of land by 2C for 29 years. The results are alarming: the area transformed from a lush, diverse grassland into a desert-like scrubland dominated by sagebrush. This 'shrubification' process, driven by rising temperatures, threatens the very existence of alpine grasslands worldwide.The experiment, conducted at the Rocky Mountain Biological Laboratory, involved warming five plots of 30 sq meters each by 2C using electric infrared radiators. The results showed a 150% increase in shrubs in warmed plots compared to those without heating. The surface soil dried by up to 20%, and shallow-rooted plants became stressed, leading to the extinction of some wildflowers.The implications extend far beyond Colorado. Alpine grasslands, which host 50% of European flora on just 3% of land, are particularly vulnerable. As temperatures rise, these ecosystems are likely to be irrevocably changed, leading to a loss of biodiversity. The phenomenon of 'shrubification' is not limited to mountain environments; it's also observed in Arctic landscapes, where shrub cover expanded by 2.2% each decade between 1984 and 2020.Conservation ecologists warn that while shrubs and trees bring benefits like shelter and carbon sequestration, their rapid expansion in cold environments is a symptom of climate change. The speed and scale of these changes are concerning, with potential knock-on impacts on the carbon cycle and ecosystem balance.As Lara Souza, lead researcher, notes, 'It's like flowers on steroids.' However, this vision of abundance is tinged with sadness at the prospect of irreversible changes to fragile landscapes. The future of these ecosystems, and many others like them, hangs in the balance as global temperatures continue to rise.

The Gran Chaco forest in Argentina, spanning across parts of Argentina, Bolivia, Paraguay, and Brazil, is facing a critical threat from deforestation. Small farmers, enticed by the promise of quick money from selling timber, often contribute to this environmental degradation. However, a collaborative effort between conservationists, NGOs, and international organizations is underway to support small-scale landowners and Indigenous communities in establishing alternative income sources. This initiative aims to enable them to resist the pressures of agribusiness and the timber market. Jorge Luna, a 55-year-old farmer, has taken a significant step towards preserving his 40-hectare land in Chaco province. He rejected an offer to cut down the trees and instead embarked on a second career as a forest tourist guide with Fundación Rewilding Argentina, a non-profit organization working to restore parts of the Gran Chaco forest. Luna now rents out a small campsite to visitors and takes tourists on kayak tours along the Bermejito River. "At first, you didn’t give the plants value. It was a lack of knowledge of what they meant. Now, every leaf that sprouts has an added value," he says. Created in 2010 by Tompkins Conservation, Rewilding aims to protect vast tracts of territory and create economic opportunities for local communities while preserving the biosphere. The organization worked with 15 other organizations to convince the government of Chaco province to turn 128,000 hectares into the El Impenetrable national park, officially designated in 2014. Since then, Rewilding has established a network to support a budding tourism industry. It offers riverside glamping stays while promoting local and ancestral knowledge as possible sources of income. Women have returned to weaving and artisanal production, as well as providing home-cooked meals for visitors. According to Greenpeace, Argentina lost nearly 7 million hectares of native forest between 1998 and 2024, with most of it in the Gran Chaco. An estimated almost 120,000 hectares of forest were lost in northern Argentina in 2024, a 10% increase from the previous year. The primary causes of forest loss are the expansion of agriculture, mainly for intensive cattle ranching and genetically modified soya, and forest fires. The Gran Chaco forest also feeds the timber industry, particularly with the quebracho tree, which produces a tannin used in leather products, and carob trees. Environmental lawyers warn that the Gran Chaco could disappear within two decades if deforestation continues at its current pace. "The Chaco does not receive the same attention as the Amazon – few people even know it exists," says Enrique Viale, an Argentine environmental lawyer and activist. For conservation efforts to succeed, projects must be co-designed with the community, ensuring their long-term objectives are considered. Community empowerment, equal distribution of benefits, and capacity building are crucial factors. Mabel Figueroa, a local weaver, has resumed her craft since the national park opened, selling scarves, blankets, and ponchos to tourists. She raises sheep and dyes their wool with tree bark and forest plants, reviving an ancestral tradition.
