Ambitious ecologist Kiala and her brother Toma journey to the Savannah Plains to capture the "voices" of the grasslands. With acoustic monitors, weather sensors, and curious hearts, they decode the whispers of wind, the stomp of elephant herds carving wildlife highways, and the dawn chorus of meadowlarks. When butterfly numbers fall, they champion wildflower rescues; as drought threatens, they invent rainwater catchments and rotational grazing games with local ranchers. At a vibrant conservation fair, their field recordings and maps ignite community action. Grassland Voices reveals how every rustle, chirp, and bloom tells a story—and teaches young readers to listen, learn, and protect Earth's vast prairies.
