Blog: Home is where the habitat is
The San Francisco Estuary (estuary) is sometimes called the most invaded estuary in the world, and for good reason. Through many avenues, hundreds, if not thousands, of species have been introduced to San Francisco Bay, the Delta, and their rivers. Some introductions were byproducts of human activity and include organisms that “hitchhiked” on the bottom of boats or as stowaways in ballast water carried by international shipping vessels. Others were deliberate and undertaken either legally by the government or illicitly by individuals for biocontrol, fisheries, or disposal of unwanted pets.
