Learn about 12 keystone species around the world from elephants to wolves, honeybees to beavers. Keystone species are animals or plants that play a crucial role in different habitats and have a huge effect on the environment around them. Entire ecosystems can depend on a single species, and they act as a glue that holds the ecosystem together.? The book will introduce readers to keystone animals across all the five major biomes (aquatic, grassland, forest, desert, and tundra) with facts about wildlife, habitats, and modern conservation practices to protect these species.
