Tiny Fish: Big Deal:
Researchers on the Oregon coast study the role that forage fish play in the food chain. Sometimes called “bait fish”, sardines, anchovies, smelt and other small fish are vitally important in sustaining larger species – including sea birds, salmon, and marine mammals like sea lions. Humans also catch forage fish, mainly for animal feed, and there’s growing concern that large-scale commercial harvesting of forage fish comes at the expense of other marine life, potentially with catastrophic results.

Wild Olympics: Spectacular Olympic National Park is the centerpiece of the verdant Olympic Peninsula in northwest Washington State, right up against the Canadian border. There’s now a bill in Congress that would add more protection to the forests and watersheds around the park, and we explore why there’s wide support for the proposal among the people living there.

Biofuel from Cornfield Residue: In another report on emerging second-generation biofuels, we travel to Iowa where farmers are discovering there’s growing demand for the residue in their cornfields – stalks, leaves, husks and cobs – left on the ground after the corn is harvested, That residue, called “corn stover”, is biomass that can also be converted into ethanol.

Fire Ants: Everybody wants to eradicate biting, invasive fire ants, but scientists say they can learn a great deal by studying the social structure of these insects. New research shows that the widespread success of fire ants has been assisted when humans disturb natural areas with roads and development.Tiny Fish: Big Deal, Wild Olympics, Biofuel from Cornfield Residue, Fire Ants

A farmer in southwestern Iowa has a mission to develop his farm as an example to others, using no-till seeding, multi-crop and pasture rotation, minimal fertilizing, and runoff filtering to keep the nutrients in his soil and prevent runoff. The backlog of deferred maintenance in national parks is a growing problem that needs Congress to act: we see the need for urgent maintenance and repairs at the Grand Canyon, the National Mall, and the Martin Luther King, Jr. Historic Site in Atlanta.

Private landowners in Pennsylvania work with government support to provide critical forest habitat for threatened populations of bats. Along the Meramec River near St. Louis, residents try to break the costly cycle of flooding, cleaning up and re-building by adopting more natural solutions to flood mitigation. Managing forest plantations in Florida, landowners use prescribed fires to reintroduce a natural process that results in healthier ecosystems for wildlife as well as better forest and ranching operations.
