The first common crane egg in the western United Kingdom in over 400 years has been laid at WWT Slimbridge Wetland Centre in Gloucestershire, England.

Common crane with eggs on nest

A round-the-clock guard has been set up to protect the egg from collectors, as despite egg collecting being illegal in the UK it is still practiced by an unscrupulous minority. Video cameras are in place to allow the public to view the nest, as well as to provide important footage for conservation scientists. Lucky visitors can also view the nest from the centre’s bird hides.

Reintroducing cranes

The common crane was once widespread across the UK, but became extinct in the region by the early 1600s as a result of hunting and the destruction of its wetland habitats. In the 1980s, a tiny group of birds began breeding in eastern England, but this population remains small.

Common cranes were once widespread in the UK, but were wiped out by hunting and the destruction of wetlands

In an attempt to re-establish breeding cranes across the UK, The Great Crane Project has been working to reintroduce common cranes to western England since 2010. Chicks have been reared in captivity before being reintroduced to the wild, and the oldest have now begun to reach maturity.

Although one pair of cranes from the project built a nest at the reintroduction site on the Somerset Levels, it was sadly abandoned. The pair of birds at Slimbridge are the first of the released birds to have laid an egg.

Absolutely momentous

This first egg is an exciting step forward in bringing back the common crane as a breeding species across the UK. Most cranes don’t usually breed successfully until they are five years old, so more breeding attempts are likely in the coming years.

Common crane eggs take around 28 to 31 days to hatch

According to Nigel Jarrett, Head of Conservation Breeding at WWT, “Cranes are an iconic part of British wildlife and one that was all but lost for centuries. There is a long way to go before cranes become widespread again, but it is absolutely momentous to see this egg laid at Slimbridge.”

“The parents of this egg were hand-reared here at Slimbridge and have thrived through their first three years on the wetlands of the Somerset Moors thanks to the help and support of the local community, particularly the farmers.”

The Great Crane Project aims to introduce around 100 resident birds by 2015 to help secure the future of this magnificent and iconic species.

Maidenhair tree (Ginkgo biloba)

Species: Maidenhair tree (Ginkgo biloba)

Status: Endangered (EN)

Interesting Fact: The maidenhair tree is known as a ‘living fossil’, as it is the only surviving member of a group of trees dating back to before the time of the dinosaurs.

A large tree with characteristically fan-shaped leaves, the maidenhair tree gets its common name from the resemblance of its leaves to those of maidenhair ferns (Adiantum species). Its leaves are greenish-yellow, but turn a beautiful golden yellow in autumn. The maidenhair tree takes 20 to 35 years to reach maturity, and can be very long lived, with the oldest recorded individual being an estimated 3,500 years old. Maidenhair trees are either male or female, with male trees producing pollen on catkin-like cones and females producing smelly, flesh-coated seeds. The maidenhair tree has been widely used in traditional medicine in China and Japan, and its nuts are edible if cooked. An extract of the plant’s leaves is now one of the most popular herbal remedies in the West, being used to treat a variety of ailments.

The maidenhair tree has been widely planted as an ornamental tree and for its medicinal properties. This species was traditionally grown in temple gardens in Japan and China, but is now popular worldwide. Unfortunately, its survival in the wild is less secure, mainly due to widespread deforestation. A few individuals are found on Mount Xitianmu in China, but it is not clear whether they are truly wild or are descended from temple garden trees. No specific conservation measures are currently in place for this unique tree, but its worldwide popularity means it is likely to persist in cultivation into the future.

This year Endangered Species Day is on the 17^th of May and here at ARKive to show our support we have decided to showcase some of the less well known endangered species.

Greater bamboo lemur 

Once widespread throughout Madagascar, the greater bamboo lemur is now restricted to just 1-4% of its historic range. The largest of the bamboo lemurs, this species was believed to be extinct for almost 50 years until it was rediscovered in 1972. The main threats to the greater bamboo lemur is habitat destruction by slash and burn agriculture, mining and illegal logging.  

Spoon-billed sandpiper

The spoon-billed sandpiper is a small, attractive bird with a distinctive spoon-shaped bill. As this species has very particular habitat requirements, only breeding in coastal areas with sand and sparse vegetation within six kilometres of the sea, habitat loss and alteration have greatly impacted upon it. Recent population surveys have shown that numbers of this species are declining rapidly. However, the Wildfowl and Wetlands Trust are taking action to save this species by setting up a conservation breeding programme to buy some time while the major problems are tackled.

Tonkin snub-nosed monkey 

Chinese giant salamander

Ploughshare tortoise 

Coco-de-mer

A giant of the plant world, the coco-de-mer is a palm species which produces the largest and heaviest seeds of any plant in the world. Endemic to the Seychelles, the Endangered coco-de-mer has already been lost from three of the Seychelles islands in its former range. The main threat to this plant species is the collection of its seeds, which has almost stopped all natural regeneration of population’s.

Saola

The saola is an unusual, long-horned bovid which was discovered as recently as 1992. The entire range of the saola is found in a narrow area of forest on the border between Vietnam and Laos. Classified as Critically Endangered, the saola is increasingly threatened as a result of hunting, as well as habitat loss and habitat fragmentation due to the development of infrastructure within its small range.   

Titicaca water frog

Endemic to Lake Titicaca, the Titicaca water frog is the largest truly aquatic frog and can weigh up to 1 kg. While its extremely loose skin gives it a bizarre appearance, the skin is very rich in capillaries, enabling the frog to remain underwater without having to surface for air. Unfortunately, the Titicaca water frog is under great threat as a result of over-collection for human consumption.

Estuarine pipefish

Believed to be extinct in the early 1990s until being rediscovered in 1995, the estuarine pipefish is still at risk of extinction. The loss of this pipefish from the majority of its former range is thought to be due to construction of upstream dams. These developments restrict the supply of fresh water which brings with it essential nutrients required by the phytoplankton upon which the food chain depends.

 These are just a few of the species which need our help – find out more about endangered species by visiting our Endangered Species topic page.

If you are a fan of ARKive, you’re a fan of wild animals. At Polar Bears International, we love all animals, but especially polar bears. In fact, we’re the champion for polar bears and are doing everything we can to help them. But we can’t do it without you. That’s why we initiated a Save Our Sea Ice (SOS!) campaign.

Mrs. McKiel’s 1st and 2nd grade students at Carpathia School in Winnipeg, Canada, created this bulletin board for the Save Our Sea (SOS!) campaign.

Polar Bears International’s SOS! campaign focuses attention on the urgent challenges polar bears face in a changing Arctic—with longer and longer ice-free periods threatening their survival—and the part each of us can play in stopping global warming, beginning with personal habits and expanding out to the community.

The campaign features a series of energy-saving efforts that begin each year on International Polar Bear Day, February 27th, and continue through the summer melt period. We’ve linked our challenges to earth awareness days, but you can launch any of these efforts at any time:

• International Polar Bear Day, February 27 – Celebrate polar bears with us by taking our Thermostat Challenge, adjusting your thermostat up or down by three degrees depending on the season. And then make every day a Polar Bear Day by switching to a programmable thermostat, insulating your home, or installing solar panels to save energy.
• Earth Hour, March 23 – Join us on Earth Hour by switching off the lights for one hour, at 8:30 p.m. local time, and make it a Polar Bear Hour by eating a cold, energy-saving meal. Then make every hour an Earth Hour through our Power Down Effort—at home, school, and in the office.
• Earth Day, April 22 – Celebrate Earth Day with us by turning off your engine for waits longer than thirty seconds when dropping off or picking up passengers at an Earth Day event. And then make every day an Earth Day by taking our No Idling Challenge and using our toolkit to set up No Idle Zones. Why? Because a surprising percentage of greenhouse gas emissions from cars, light trucks, and vans come from idling engines with no transportation benefit.
• Endangered Species Day, May 17 - Help polar bears and other endangered species every day by Sizing Up Your Pantry. Take stock of your pantry and think about your food choices, recognizing that fewer food miles, organic farming methods, and minimal processing and packaging have less impact on the planet—and can help reduce the greenhouse gas emissions that cause global warming.
• World Oceans Day, June 8 - Take action for polar bears and the sea ice they depend on every day with our Green House Grocery List. Begin by assessing your typical week’s grocery list to see how you measure up; then make adjustments where you can. Why? Because your food shopping habits can help reduce the greenhouse gas emissions that are causing the planet to warm and the sea ice to melt.

A polar bear family jumps from floe to floe in a melting Arctic. To save arctic sea ice, we must each do our part to reduce greenhouse gas emissions.

To save polar bear habitat, we need to embrace sustainable living as a society. A promising shift is underway in sectors including transportation, energy usage, and food production—all of which have an impact on greenhouse gas emissions. You can become part of the momentum for change by modifying your own habits and taking action in your community in support of greener choices—from bikes lanes to farmer’s markets—that make a low-carbon lifestyle easier.
