Amphibians are a group of cold-blooded vertebrates which includes the frogs, toads, newts, salamanders and the lesser-known, worm-like caecilians. Most amphibians spend part of their life in water as aquatic larvae and part on land as terrestrial adults, but some species live permanently in water or permanently on land.

In all, there are over 6,000 amphibian species, and amphibians inhabit all continents except Antarctica, living in habitats ranging from rainforests to deserts. However, amphibians have undergone dramatic declines across the world and are currently facing an extinction crisis. Urgent conservation action is now needed to prevent many species from becoming extinct.

Amphibian crisis

Almost half of all amphibian species are thought to be declining, and a third are at risk of extinction, making this the most threatened group of animals on the planet. Around 165 species are thought to have gone extinct in recent times, and many more are likely to be lost in our lifetime.

A staggering 500 species are facing threats that cannot be dealt with quickly enough to prevent their extinction, so are in desperate need of ex-situ conservation measures such as captive breeding.

Threats to amphibians

Amphibians face a variety of threats, including habitat loss, climate change, invasive species, and collection for food and the pet trade. With their thin, permeable skins, amphibians are also particularly sensitive to pollution.

However, one of the greatest threats to amphibians is the lethal fungal disease chytridiomycosis, which has contributed to the rapid disappearance of many amphibian species across the world. The spread of this deadly disease may be exacerbated by climate change.

Why conserve amphibians?

Amphibians play a key role in the food chain, both as predators and as prey for many other animals. They also help to control pests, benefitting human agriculture and reducing the spread of insect-borne diseases. As they are particularly sensitive to environmental changes, amphibians are also important indicators of the overall health of the environment.

In many cultures, amphibians are cherished as signs of life and good luck, and some amphibians are eaten as food. In addition, many amphibian species have substances in their skin that can have important medical uses.

As well as benefitting humans and ecosystems, amphibians are a fascinating group of animals in their own right, with many intriguing physical and behavioural adaptations.

Amphibian conservation

A range of conservation measures are underway to try and combat the crisis facing amphibians. These include habitat protection, education and awareness campaigns, and captive breeding of threatened species. An action plan is also in place to coordinate global conservation efforts for amphibian species.

In 2010, the IUCN SSC Amphibian Specialist Group (ASG) and Conservation International (CI) launched a global search for amphibian species which have been ‘lost’ to science. Named the ‘Search for Lost Frogs’, this has resulted in numerous expeditions and the rediscovery of some species previously feared extinct, including the Hula painted frog and the Rio Pescado stubfoot toad. However, many more species remain missing, underlining the desperate situation that many amphibians are facing.

The Hula painted frog was believed to be extinct, but was rediscovered by scientists in 2011

Efforts are underway to breed some amphibians in captivity until they can safely be released back into the wild. Unfortunately, the global zoo community is only able to manage around ten percent of threatened amphibian species at best, and more work still needs to be done to safeguard these vitally important but highly threatened species.

Although it may not feel like it with all the cold weather we’ve been having recently, here in the UK we are well into spring and heading towards summer. As the temperatures begin to creep up, now is the perfect time to get out and about and start exploring the diverse range of habitats the UK has to offer. Being an island, the UK boasts over 6,000 kilometres of shoreline, and heading down to the seaside is a popular pastime for people of all ages. It is said that in the UK you are never more than about 70 miles from the sea, so why not make a day of it and visit one of the beautiful sandy beaches that our coastline has to offer?

While sandy shores may not seem an obvious place to find wildlife, a wealth of invertebrate and fish species live below the sand, buried out of sight. If you are lucky, you may also spot seals hauled out on the beach, or shorebirds foraging for prey in the sand or among the debris of the strandline. Visitors to beaches such as Studland on Dorset’s Jurassic Coast could be treated to an even rarer sight, as sand lizards can be spotted here in the dunes and heathland which border the beach.

Certain beaches are renowned for their bird life, such as Titchwell Marsh on the north Norfolk coast. Here you can see curlew sandpipers, avocets, redshank and many other waders, particularly in the summer and autumn. Looking further north, Balranald on the Outer Hebrides is another haven for a number of bird species, inlcuding  little terns which can be spotted fishing along the shore.

Of course, part of the fun of heading to the beach is spotting signs of invertebrate life, and I’m sure that like me, many of you spent hours of your childhood searching for shells and other treasures. If you fancy re-living your youth, or you’d like to introduce the next generation to the wonders that wash ashore, make sure you take along a copy of our beach treasure hunt activity next time you visit the seaside; a PDF version can be downloaded here.

Coastal sand dunes are typically formed as the wind blows sand into drifts which get trapped around plants such as marram grass, the roots of which help to hold the dune together. These dunes are a great place to find other plant life too, including species such as sea holly, sea spurge, centaury and prickly saltwort.

Why not take a look at our new UK sandy shore feature page for more information and inspiration, and start planning your next trip to the beach? We’ve got details of the species you might encounter, ideas and tips on choosing where to visit and even suggestions about how you can get involved and help to protect and preserve our coastline.

Atlantic forest canopy

The Atlantic forest now covers only 8% of its historical range

Despite being one of the most diverse and biologically rich forests in the world, the Atlantic forest in South America is unfortunately also one of the most threatened. Only about eight percent of its original cover remains and its total area has been dramatically reduced to just less than 100,000 square kilometres. If we flip this figure; compared to the Amazon which has lost around 20% of its forest, the Atlantic forest, or Mata Atlântica as it is also known, has seen a staggering 92% decline. To make matters worse, what remains of the forest is severely fragmented and only two percent is still considered to be primary, or pristine, forest.

Only 2% of the Atlantic forest is now considered to be primary forest

The Atlantic forest extends along Brazil’s eastern coast, into Paraguay and northeast Argentina. It is home to thousands of species that are not found anywhere else in the world; for example, no fewer than 8,000 of the total 20,000 or more plant species are totally unique to the Atlantic forest, including over half of the forest’s trees. Examples include the Endangered Pau brasil and the Vulnerable Brazilian rosewood tree. But it’s not just the plants: there are many mammals, birds, reptiles, amphibians, fish and invertebrates that are found exclusively in the Atlantic forest. As more of the forest is degraded and fragmented by deforestation, these species are increasingly at risk of extinction.

Deforestation in the Atlantic forest is a result of human settlement, dating back centuries to when Europeans arrived in South America and began to clear forest to make way for timber and cattle ranches, as well as to grow crops such as sugarcane, coffee and cocoa. In more recent years land use has shifted towards soy cultivation and pine, tobacco and eucalyptus plantations. The spread of invasive species and the ever-looming presence of climate change are also playing their part, providing competition for food and resources, and decreasing the resiliency of species to changes in their environment.

Of the 100,000 remaining square kilometres, only approximately 23,800 square kilometres are under protection; less than 2% of the forest’s historic range. There are, however, also a range of conservation initiatives working to protect and restore parts of the Atlantic forest.

One such reforestation project by The Nature Conservancy began in 2008 with the ambitious aim of planting one billion trees in Brazil’s Atlantic forest within seven years. If successful, the ‘Plant a Billion Trees’ project will repopulate 2.5 million acres of land, increasing the forest’s significance as a carbon sink that will potentially be able to remove four million tonnes of carbon from the atmosphere each year. As numbers currently stand, 12,574,689 trees have been planted, with one tree planted per dollar donated. Despite being far from the target, this level of reforestation is still significant.

The Nature Conservancy are not alone in their bid to reforest areas of the Atlantic forest. The Alstom Foundation’s project aims to promote long-term sustainability in the remaining forest, and to reconnect fragmented areas which will help to support wildlife. Its target is to restore 15 million hectares of degraded lands by the year 2040, amounting to 12 percent of the forest’s original ecosystem.

While we could go ahead and list every project working to reforest areas of the Atlantic forest, the important message to take from this is why these collective efforts are significant. Many species are on the verge of being lost from the Mata Atlântica, including the jaguar, lowland tapir and giant anteater, and many more species will continue to decline if further action is not taken. Large numbers of these species occur nowhere else in the world, and they require large areas of connected forest to survive and reproduce.

With climate change on the tip of everyone’s tongue, restoration in this forest could serve to provide a much-needed carbon sink, able to remove and store huge amounts of carbon from the atmosphere. Reforestation projects are also able to help local communities to build their knowledge of soil use, conservation and land management, enabling them to protect their land in the future and encouraging them to undertake their own forest restoration, thereby continuing reforestation efforts in the long-term.

It’s National Wildlife Week in America and a perfect excuse for us to comb the ARKive collection for species in support of this year’s theme, ‘Branching Out for Wildlife’ – celebrating trees and their importance to wildlife and people.

Trees are essential for species survival around the world. They provide vital habitat for species in nearly every category from mushrooms to mammals and everything in between. Their leaves clean the air we breathe and their wood provides invaluable ecosystem services to humans. Basically, we just couldn’t survive without them!

We thought we’d showcase some of our favorite images on ARKive featuring species ‘branching out’ in their own ways. Take a look; you might be surprised at some of the species on our list!

Ring-tailed clinger

You may have spotted a Northern raccoon scampering around the forest floor but this species is actually right at home climbing in and around the limbs of trees. For a more classic image of raccoons and trees, take a look at these cuties.

ARKive's common garter snake species profile

Did you know that some snakes could climb trees? Snakes like this red-sided garter snake are able to slither their way up trunks and limbs to avoid predators or, in this case, to escape from a pining male suitor.

Fir-climbing feline

ARKive's Canada lynx species profile

You’ve probably heard the story of the little house kitty that got stuck up in the tree, right? Well, the far distant cousin of the house cat, the Canada lynx, has no problem ambling up and around the trees in its native habitat. On the ground, these cats rely on fallen trees, among other shrubbery, for cozy bedding.

Pine tree pecker

ARKive's pileated woodpecker species profile

No collection of tree-dwelling species would be complete without a woodpecker which uses its powerful beak to ‘peck’ holes into tree trunks to create a home. Woodpeckers like this pileated woodpecker are especially important to the woodland ecosystems since vacated woodpecker homes provide essential shelter for other species such as owls, bats and swifts.

Branching bear

ARKive's brown bear species profile

While the large claws of the brown bear are better suited for digging rather than tree climbing, it certainly doesn’t stop this opportunistic feeder from climbing up a trunk or two for a meal.

Can you think of other American species that require trees to live? Why not do some exploring around the Wisconsin’s Northwoods or the Eastern deciduous forest of the US. Shout out your favorite species in the comments below and include a link to the species on ARKive so we can learn together!

What do you get when you combine art supplies, ARKive’s amazing collection of endangered species imagery and fact files and creative young minds?  A unique, one of a kind learning experience called the ARKive School Museum which transforms classrooms and schools into a natural history museum all about endangered species.

The ARKive School Museum is an innovative and engaging educational experience which encourages students to get creative. By discovering fascinating biological facts about endangered species, designing and creating fun, interactive exhibits, and hosting unique, hands-on activities in their own ‘museum’, students improve their scientific literacy and develop cross-discipline skills that they can apply to an ever-changing global society.

Designed for students from 5-14 years of age, the ARKive School Museum begins with them diving into the world of conservation and learning how species become endangered. Then, by choosing a species to learn about further, students use ARKive as a scientific research tool to discover biological information and interesting facts that can be transformed into an interactive exhibit to inform the wider school community about the species and issues.  With optional museum-focused extension activities, students can explore the world of museum curation for additional exhibit tips and tricks.

An ARKive School Museum culminates with a ‘grand opening’, where students lead visitors through the interactive exhibits they have designed. Students engage and amaze visitors as they showcase the results of their hard work and communicate their findings about endangered species to fellow students, parents and their local school communities.

The ARKive team worked with classrooms in Virgina, USA, to pilot the ARKive School Museum program and we were consistently amazed by the creativity of the students. From constructing pitch black naked mole rat tunnels from cardboard boxes that challenged museum visitors to experience living underground and without vision to designing a measurement exhibit using string to illustrate the length of saltwater crocodiles (the largest living reptile) and other species, there seemed to be no end to what the students could dream up! One of the teachers we worked with said it best,

“We see students being transformed from just acquiring knowledge to discovering that learning has a purpose – the sharing of knowledge”. – Bailey’s Elementary School for the Arts and Sciences, Virginia, USA

We couldn’t agree more! To create an ARKive School Museum in your school or classroom, start by visiting ARKive Education today. Then, select the guiding materials that fit your students’ ages, learning styles and needs.
