Translating area-based conservation pledges into efficient biodiversity protection outcomes

Cunningham et al. comment on the U.K.’s commitment to protect 30% of land by 2030, by identifying priority landscapes for expansion of the current protected area network in the UK using 445 priority species ranges across the country, under two baseline protection definitions to reach this conservation target. They find that expanding the protected area network by initially only including the strictest protected areas would yield much greater representation of threatened species, and propose new considerations for protected area commitments.
