The estuaries of the Southeast — from the Chesapeake Bay to the Texas Laguna Madre, across more than 30,000 miles of tidal shoreline — are among the most productive ecosystems on Earth, the nursery for most of the region's coastal fish and shellfish. This synthesis covers the inshore-saltwater system: the marsh-grass detrital engine that feeds it, the three kinds of estuary, the marsh-mangrove-seagrass-oyster habitats, the keystone species, and the threats reshaping the coast

The American black bear is one of the Southeast's quietest conservation successes — recovered from early-1900s remnants to a regional population now estimated above 55,000, from the southern Appalachians to the Okefenokee and Big Cypress. This synthesis covers the ecology: the island-population structure and its recolonization, the mast-driven seasonal cycle and denning gradient, the large-landscape habitat and corridor needs, and the recovery-and-conflict arc at the suburban

Invasive species are remaking the Southeastern outdoors — but the honest 2026 picture separates the genuinely destructive from the over-hyped. This field report covers the worst current invaders, from Burmese pythons and jumping silver carp to lionfish, feral hogs, hydrilla and the bald-eagle disease it carries, and the forest pests warming trout streams — with the current outlook and how each is hurting the environment, the operators, and the tourism economy.

The Mississippi Flyway handles an estimated 40 percent of North America's duck and goose migration -- more waterfowl than any other flyway on the continent. This synthesis covers flyway structure from the prairie pothole breeding grounds through the Gulf Coast wintering grounds, the four food systems of the MAV, Louisiana's 2,000-square-mile coastal land loss, and the climate-driven migration shift redistributing birds northward.

The southeastern United States is one of the most biologically rich temperate regions on Earth -- holding roughly 550 freshwater fish species, the highest salamander diversity of any region in the world, and a convergence of ecoregions that has no parallel in the Northern Hemisphere.
