Asian carp have big appetites and can leap out of the water when startled. They were brought to the United States from their native Asian habitats to control algae growth on fish farms. Find out what happened when some of these big, jumping fish escaped and made their way up the Mississippi River.
Gray squirrels are known for their bushy tails and hoarding habits. These North American natives were imported to parts of Europe and South Africa as pets, but quickly went from pets to unwanted pests. Learn more about the problems caused by invasive gray squirrels and what can be done to solve them.
American mink have beautiful, thick, glossy fur. At one time, many were exported to other countries where farmers raised them for their fur. Find out what happened to native species when fur went out of fashion and many minks were released into the wild.
Emerald Ash Borers have shiny green bodies and an appetite for ash trees. This native Asian insect hitchhiked to North America and has killed millions of ash trees. Learn more about the emerald ash borer and what is being done to try to stop its spread.
Cane toads are known for their warty skin and poison glands. They were brought to Australia and other places to help control pests that were harming crops. Learn more about how the cane toad has gone from being farmer's friend to an unwanted pest.
Honeybees are known for their familiar buzzing and honey production. Learn how an experiment meant to increase honey production created aggressive Africanized honeybees that have taken over territory and caused big problems for beekeepers, farmers, and anyone unlucky enough to disturb them.
The Florida panther once roamed as far west as Louisiana and as far north as Tennessee. Today, these cats are found in just four counties in southern Florida. How did the Florida panther become one of the most endangered animals in the world? Read this book to find out how hunting and other human activities brought the Florida panther to the brink of extinction. Learn what is being done to help it get on the road to recovery.
The grizzly bear once roamed much of western North America. In the early 1800s, as many as 50,000 grizzly bears lived in the West. As settlers pushed westward, the bears lost much of their habitat. Fewer than 1,000 grizzlies remained in the lower 48 U.S. states when the bear was listed as endangered. Read this book to learn how grizzly bears came close to extinction and find out what is being done to increase their numbers and insure their survival.
The bald eagle is known to people around the world as a symbol of the United States. In the early 1800s, as many as 100,000 bald eagles lived in the United States. By the 1960s, the familiar bird of prey was nearly extinct. What happened? Read this book to find out how human activity brought the handsome eagle close to extinction. Discover how human efforts helped it fight back and once again become a familiar sight in North American skies.
The California condor is the largest bird in North America. Scientists have found condor fossils that are nearly 100,000 years old. As more people settled in the American west, however, condors lost much of their habitat to human development. By 1982, fewer than 25 California condors lived in the wild. Read this book to find out more about California condors, how they came close to extinction, and what people are doing do help make sure condors stay on the road to recovery.

When we think of wild animals, we don't immediately associate them with the cities we live in. But a closer look soon reveals that we share our urban environment with a great many untamed creatures. Heavily illustrated and full of entertaining and informative facts, City Critters examines how and why so many wild animals choose to live in places that, on first glance at least, seem contrary to their needs. How do those deer, raccoons, squirrels, skunks, coyotes, crows, gulls and geese-not to mention the alligators, eagles, otters and snakes-manage to survive in the big city? What special skills do city critters have that many of their wilderness cousins lack? Why have they developed these skills? And what are our responsibilities in ensuring that these animals can continue to share our city lives?
The Sea Wolves sets out to disprove the notion of "the Big Bad Wolf," especially as it is applied to coastal wolvesa unique strain of wolf that lives in the rainforest along the Pacific coast of Canada. Genetically distinct from their inland cousins and from wolves in any other part of the world, coastal wolves can swim like otters and fish like the bears with whom they share the rainforest. Smaller than the gray wolves that live on the other side of the Coast Mountains, these wolves are highly social and fiercely intelligent creatures. Living in the isolated wilderness of the Great Bear Rainforest, coastal wolves have also enjoyed a unique relationship with man. The First Nations people, who have shared their territory for thousands of years, do not see them as a nuisance species but instead have long offered the wolf a place of respect and admiration within their culture. Illustrated with almost one hundred of Ian McAllister's magnificent photographs, The Sea Wolves presents a strong case for the importance of preserving the Great Bear Rainforest for the wolves, the bears and the other unique creatures that live there.
Extensively illustrated with Ian McAllister's magnificent photographs, The Salmon Bears explores the delicate balance that exists between the grizzly, black and spirit bears and their natural environment, the last great wilderness along the central coast of British Columbia. Key to this relationship are the salmon that are born in the rivers each spring, who then go out to sea as juveniles and return as adults to spawn and die, completing a cycle of life that ensures the survival of not only their own species but also virtually every other plant and animal in the rainforest. In clear language suitable for young readers, the authors describe the day-to-day activities that define the lives of these bears through the four seasons. But this is also very much the story of the Great Bear Rainforesta vast tract of land that stretches from the northern tip of Vancouver Island to the Alaska border and contains some of the largest stands of old-growth forest left on the West Coast. The Salmon Bears focuses on the interconnectedness of all life in the rainforest and makes a strong case for the importance of protecting this vital ecological resource.
