Shifts in bird ranges and conservation priorities in China under climate change

3.4 Conservation gaps for future priority areas Priority maps of birds based on range areas and the percentage changes for distribution range show the priority candidates for new protected areas (Fig 5; A and B show the random scenario, C and D show the NNRs masked scenario). The updated Zero Draft of post 2020 CBD Frame- work proposed a new target of 30% of territorial areas for biodiversity conservation [70], which we used to obtain the ranges of priority areas (shown in red, orange and yellow in of Fig 5). For RCP 2.6 in random scenario (Fig 5A), the top priorities included the 1) the Altai Moun- tains; 2) the Tianshan Mountains; 3) the Karakoram Mountains; 4) the southeastern Tibet basin; 5) the eastern Qilian Mountains; 6) the three-province border area of Qinghai, Gansu, and Sichuan; 7) the Qinling Mountains; 8) the Three Parallel Rivers areas; 9) central Yunnan mountains; 10) south Yunnan; 11) the Greater Khingan area; 12) the Songnen Plain; 13) the Fig 4. Richness maps and richness changes under different climate change scenarios for bird species in China. The figures arranged in three columns show “all species” group, “migratory” group, and “resident” group separately. A-C are the current richness maps; D-F are the richness changes under RCP 2.6; and G-I are the richness changes under RCP 8.5.
