Achieving the 30x30 goal, as it is known, requires much more than declaring more national parks
The U.S. covers a vast array of ecosystems, from Alaska’s Arctic tundra to Florida’s tropical swamps, with prairies, snow-capped peaks and deserts in between. Like the rest of the planet, humans are putting those ecosystems under enormous strain as we convert land to agriculture and urban development, release myriad pollutants and burn fossil fuels that spew heat-trapping greenhouse gases.
To make sure conservation plans capture disparate ecosystems, lots of data must be gathered to reveal which tracts are already being protected and where the gaps are. To that end, the Biden administration is working on the American Conservation and Stewardship Atlas, which will be “the first comprehensive nationwide snapshot of what lands and waters in America are currently protected,” O’Shea says. An initial version of the atlas is scheduled for release by the end of the year.
Though a higher percentage of U.S. ocean area is protected, compared with land, most of it is far out in the central Pacific ocean—in particular, in Papahānaumokuākea Marine National Monument. Many more types of ocean ecosystem protections are needed around a much broader swath of the country’s seas, says Lisa Suatoni, deputy director of NRDC’s oceans program.
That connectivity can take several forms, and they do not need to have the same level of protection, Stein says. An example is formal wildlife corridors, such as one breaking ground this week in Los Angeles County. It will allow the mountain lions of the Santa Monica Mountains, which have been cut off genetically from other populations, to mix.
