Retaining natural vegetation to safeguard biodiversity and humanity
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and seminatural (e.g., low intensity or sustainable human use) forests, woodlands, and ...
