Broadcast over three consecutive days from iconic locations across North America – varied ecosystems ranging from the Rockies to the Everglades, from inner-city parks to remote wilderness preserves - this special live event celebrates spring as a time of renewed energy and awakening in the natural world.

Breeding and the greening of the landscape are tied to another major spectacle of spring: the mass movements of animals as they take advantage of spring’s bounty. Meet the scientists who track the journeys of animals such as butterflies, birds, bison and bats over vast distances, from winter refuge to spring nesting grounds.

Learn how plants and animals depend on each other to survive. See first-hand how climate change can break those connections, altering the timing of weather and plant growth, and disrupting the delicate relationships between plants and pollinators such as moths, bees and butterflies.
