A critically endangered species’ extent of occurrence is less than 100 square kilometers (39 square miles). A critically endangered species’ area of occupancy is estimated to be less than 10 square kilometers (4 square miles). I bought this for my nephew who has a form of dyslexia. He is into conservation and all things animals, and I hoped it would delight him. It has! He doesn't waste words but this was a message I received. For each of the 20 endangered species she talks to an expert - whether that be researcher, conservationist, indigenous person to add insight. The definitions of the three threatened categories (vulnerable, endangered, and critically endangered) are based on five criteria: population reduction rate, geographic range, population size, population restrictions, and probability of extinction. Hexham Book Group's meets on the second Tuesday of the month at 7.30pm in Scott's Café at the Forum Cinema, Hexham.

Least concern is the lowest level of conservation. A species of least concern is one that has a widespread and abundant population. Human beings are a species of least concern, along with most domestic animals, such as dogs and cats. Many wild animals, such as pigeons and houseflies, are also classified as least concern. There are plenty of species left to cover – I’m looking forward to the next volume already. And I keep daydreaming about camels. Joyful and heartbreaking, an inspiring celebration of some of our planet's most endangered species and those who champion them' - Dave Goulson, author of Silent Earth This is a must read for all children & young people. Beautifully written - Megan explains in the intro she is dyslexic & struggled reading books when she was at school. She has written this book in a very readable way. With twenty percent of the earth's species facing extinction by 2030, this striking atlas brings up to date the data on those that have been lost already, those that are threatened, and those that are surviving today. Vividly illustrated with full-color maps and detailed graphics, The Atlas of Endangered Species catalogs the inhabitants of a wide variety of ecosystems, including forests, mangroves, and coral reefs. It examines the major threats to biodiversity, from loss of habitat to hunting, and describes the steps being taken toward conservation.Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms. This can happen in a number of different ways.

The Ethiopian banana frog ( Afrixalus enseticola) is a small frog native to high- altitude areas of southern Ethiopia. It is a vulnerable species because its area of occupancy is less than 2,000 square kilometers (772 square miles). The extent and quality of its forest habitat are in decline. Threats to this habitat include forest clearance, mostly for housing and agriculture. A near threatened species is one that is likely to qualify for a threatened category in the near future. An Atlas of Endangered Species: stories from the brink of extinction – and the fight for survival by Megan McCubbin is published by Two Roads. We meet those who are engaged in preventing these species from being driven to extinction and hear their stories of success and sometimes of frustration. The interviews were carried out by Zoom (a phrase that wouldn’t have meant much to me a few years ago) as the research was done over the covid period. This is a good model – does the author pull it off? She does. Probability of extinction in the wild is at least 50 percent within 10 years or three generations, whichever is longer.

Species with fewer than 10,000 mature individuals are vulnerable. The species is also vulnerable if that population declines by at least 10 percent within 10 years or three generations, whichever is longer. Habitat loss from development in the 20th century is the main reason the tree went extinct in the wild. A single specimen survived at the Royal Botanical Garden in Peradeniya, Sri Lanka, until 1990, when that, too, was lost. The International Union for Conservation of Nature (IUCN) keeps a “Red List of Threatened Species.” The Red List de fines the severity and specific causes of a species’ threat of extinction. The Red List has seven levels of conservation: least concern, near threatened, vulnerable, endangered, critically endangered, extinct in the wild, and extinct. Each category represents a different threat level. Probability of extinction in the wild is at least 20 percent within 20 years or five generations, whichever is longer. Population restriction is a combination of population and area of occupancy. A species is vulnerable if it is restricted to less than 1,000 mature individuals or an area of occupancy of less than 20 square kilometers (8 square miles).

The Sri Lankan legume tree ( Crudia zeylanica), native only to the island of Sri Lanka in the Indian Ocean, was a giant species of legume. Peas and peanuts are smaller types of legumes. There are currently 41,415 listed endangered species, and over 16,000 of them are threatened with extinction.Many species of violets, native to tropical jungles in South America and Africa, are near threatened, for instance. They have healthy populations, but their rain forest habitat is disappearing at a fast pace. People are cutting down huge areas of rain forest for development and timber. Many violet species are likely to become threatened.

The snaggletooth shark ( Hemipristis elongatus) is found in the tropical, coastal waters of the Indian and Pacific Oceans. Its area of occupancy is enormous, from southeast Africa to the Philippines, and from China to Australia. The Cuban macaw ( Ara tricolor) was a tropical parrot native to Cuba and a small Cuban island, Isla de la Juventud. Hunting and collecting the birds for pets led to the bird’s extinction. The last specimen of the Cuban macaw was collected in 1864. A species is extinct when there is no reasonable doubt that the last remaining individual of that species has died.Joyful and heartbreaking, an inspiring celebration of some of our planet’s most endangered species and those who champion them’– Dave Goulson, author of Silent Earth Hexham Book Festival is a Not For Profit CIC and delivers an annual festival that takes place in and around Hexham each year. When a species is classified as endangered, governments and international organizations can work to protect it. Laws may limit hunting and destruction of the species’ habitat. Individuals and organizations that break these laws may face huge fines. Because of such actions, many species have recovered from their endangered status. Three species vanish every hour. Our incredible world is at risk, and we all have a part to play in saving it.
