Waitrose removed fresh, chilled, and frozen mackerel from all its UK stores. Tinned mackerel will follow once existing stock runs out. The decision came after governments failed to reduce mackerel catches to sustainable levels recommended by scientists.

Mackerel stocks in the North-east Atlantic have declined significantly, plummeting 75% over the past decade due to overfishing. Conservationists have welcomed this decision and urged other supermarkets to follow suit.

Jake Pickering from Waitrose stated, “By suspending sourcing of mackerel at Waitrose, we are reinforcing our ethical and sustainable business commitments.” He emphasized the need to tackle overfishing and protect ocean health.

Waitrose plans to introduce 100% MSC-certified frozen sardines as a sustainable alternative. This aligns with the Sustainable Seafood Coalition codes of conduct.

The fishing industry faces pressure as mackerel stocks continue to decline. Four coastal states decided on a 48% cut in mackerel catches, but many believe more action is necessary.

No timeline has been shared for when Waitrose might resume sourcing mackerel. However, they aim to maintain relationships with their suppliers during this period.

Charles Clover, a conservationist, remarked, “This crisis has been ignored for too long. We hope that this action by Waitrose sends it to the top of the political agenda.”

Woody, a specially trained red fox labrador, has made significant contributions to wildlife conservation on Rathlin Island, Northern Ireland. His efforts have led to the successful elimination of ferrets that were threatening local seabird populations. As a result of Woody’s work, the island is now ferret-free, and experts anticipate a rise in seabird populations in the coming months.

In a separate wildlife incident, a capybara named Samba has escaped from a zoo in Suffolk. Capybaras, known as the largest rodents in the world, are typically found in South America. Samba was last seen near the River Itchen before swimming away, prompting a search effort that includes a specialist dog unit to locate her.

A spokesperson from the zoo commented on the search for Samba, stating, “The team remained determined to do everything we can to bring Samba home safely.” They also noted that the search area has been narrowed down, allowing for better deployment of thermal drones to assist in locating the capybara.

In the realm of transportation and logistics, dynamic testing of trains on the Tren Maya line in Mexico commenced in late February. This line is expected to open for freight operations by late 2026, marking a significant development in the region’s infrastructure.

However, the train operator ŽRS is facing challenges, with a reported 60% drop in freight revenues due to the suspension of iron ore deliveries. In response, Uzbekistan’s President announced a $100 million allocation for the production of 1,350 wagons to bolster freight capabilities.

Additionally, the Hupac Group has ordered two CZ Loko EffiShunter 1000 locomotives for use at intermodal terminals, further enhancing logistics operations in the area. Olli Pohjanvirta, CEO of Nurminen Logistics, emphasized the importance of combining dedicated block trains with flexible part-load shipments to provide reliable and efficient transport solutions.

As the situation develops, observers are keenly watching how these conservation efforts and logistical advancements will unfold in the coming months.

The large tortoiseshell butterfly is now a resident species in the UK after being declared extinct in the last century. This remarkable development marks a significant milestone in conservation efforts, particularly for Butterfly Conservation, which has classified the species as resident for the first time in its 58-year history.

Sighting Locations and Population Growth

Recent sightings of the large tortoiseshell have been reported in woodlands across several regions, including Kent, Sussex, Hampshire, Dorset, Cornwall, and the Isle of Wight. With the return of this species, Britain’s native butterfly count has increased to 60, highlighting a positive trend in biodiversity.

Historical Context and Factors for Return

The large tortoiseshell butterfly last flourished in Britain during the 1940s but was considered extinct by the 1960s, primarily due to factors such as Dutch elm disease. The species is believed to have returned due to population rises in the Netherlands and France, alongside climate change, which may have created more favorable conditions for its survival and reproduction.

Breeding and Lifecycle

Caterpillars of the large tortoiseshell have been found feeding in the wild since 2020, confirming that the butterfly is breeding again in Britain. The caterpillars primarily feed on elm, willow, aspen, and poplar. The adult butterflies hibernate during the winter months and emerge in spring to mate and lay eggs, with the offspring expected to take flight during midsummer.

Public Involvement and Future Monitoring

Butterfly Conservation is actively encouraging the public to log sightings of the large tortoiseshell using the iRecord app, which will aid in monitoring the population and distribution of this species. Richard Fox from Butterfly Conservation stated, “The signs are really positive, which is lovely,” emphasizing the importance of public engagement in conservation efforts.

Ongoing Uncertainties

Despite the encouraging signs, details remain unconfirmed regarding whether the large tortoiseshell will become widespread across multiple landscapes in the UK. Richard Fox noted, “We’re still in that zone of uncertainty at the moment, but there are exciting signs,” indicating that while the situation is hopeful, further observation is necessary.

The classification of the large tortoiseshell butterfly as a resident species is a significant achievement for conservationists and a testament to the resilience of nature. As efforts continue to monitor and support this species, the future looks promising for the large tortoiseshell in the UK.
