“…The definition of species richness is the number of species contained in a grid cell (Prendergast et al, 1993). Because the threshold of 5% is most commonly used, we identified hotspots of species richness based on the top 5% of grid cells with the highest species richness (Huang et al, 2014a; Zhao et al, 2016; Shrestha et al, 2018). The top 5% of the land area is equivalent to approximately 200 grid cells.…”

“…Therefore, we should focus on the importance and urgency of conservation and strengthen priority conservation planning. Protected areas play an important role in biodiversity conservation (Huang et al, 2014b;Zhang et al, 2017;Gao et al, 2021) and are the most direct and effective method used to protect species of NKPWPs and their habitats (Chen et al, 2009). The NNRs play key roles in in situ conservation efforts, protecting 44.7% of NKPWPs.…”

National key protected wild plants (NKPWPs) are species with important conservation value based on genetics, ecology, culture, and/or scientific research, which are also confronted with serious threats. However, their geographical distribution patterns and conservation status remain unclear. In this study, we compiled 1032 species of NKPWPs. We measured the diversity to identify hotspots of NKPWPs based on species richness, weighted range size rarity and a complementarity‐based analysis. Comparing the distribution and hotspots of NKPWPs with the coverage of Chinese nature reserves (NRs), we assessed conservation effectiveness and identified conservation gaps. The results identified 13 diversity hotspots; only 9.5% of them were covered by NRs with >30% of the grid cell area, and even 19.5% were not covered at all by NRs. Overall, 44.7% of NKPWPs were effectively protected by national NRs. Despite this success, 571 species in Yunnan, Guizhou, Sichuan, Chongqing, Guangxi, Guangdong, southern Hainan, Taiwan, and northern Xinjiang remain unprotected by NRs. The protected proportion of plants with first‐level protection was lower than that of plants with second‐level protection. The low overall proportion of protected hotspots indicates that the conservation outlook for NKPWPs is not optimistic. This study identifies priority conservation areas and conservation gaps and provides a scientific reference for the conservation of wild plants in China.

“…As a number of environmental factors directly affect the survival strategies of waterbirds and determine their habitat selection [12], an understanding of the relationship between these factors and habitat importance is fundamental for devising effective management strategies [13]. A further important conservation approach is to identify protection gap areas by overlaying the distributions of important habitats and protected areas using spatial analysis tools [14,15].…”

Wetlands are among the most important habitats of highly wetland-dependent waterbirds but are subject to ongoing habitat loss and degradation owing to intensified anthropogenic activities. The scarcity of human and natural resources makes effective habitat protection an important concern. Here, we aimed to investigate waterbird habitat protection methods for Anhui Province, China, a critical stopover and wintering area on the East Asian-Australasian Flyway that features rich wetland resources subject to significant habitat loss and degradation. We evaluated the status and importance of 306 wintering waterbird habitats and identified the key environmental influences and current protection gaps using the entropy weights method and generalized additive modeling. We found 73 important habitats for waterbirds in Anhui Province, which were classified into levels of importance (descending from I to V) according to the natural discontinuity method. Level I and Level II habitats were mainly located in the Yangtze River floodplain and Level IV habitats in the Huaihe River floodplain. The gap analysis showed that 42 important waterbird habitats had protection gaps, accounting for 57.53% of the total area. Waterbird habitat importance was significantly correlated with elevation, normalized vegetation index, lake area, and lake circumference but not with distance from roads or population density. The results of this study provide scientific information for waterbird habitat conservation planning, which is crucial for maintaining wetland ecosystem functions.

Research on vacancy analysis and spatial layout of protected natural areas has been carried out for many years around the world, but most of the research objects are land-type protected natural areas, while studies on Marine protected natural areas are relatively rare, and there are few cases to carry out integrated optimization research on spatial layout of protected natural areas. This study will take Changdao in Yantai, Shandong Province, China as an example, from the protection of how much? How representative? Where is it protected? Starting from the three problems, the vacancy analysis is carried out, and the integrated optimization research is carried out based on the existing spatial layout, aiming at the rescue protection, coordinated protection and forward-looking protection. The results show that the integrated and optimized Changdao protected area eliminates the protection vacancy, integrates the overlapping protected areas, optimizes the unreasonable protected space, alleviates the contradiction between protection and development, promotes the coordinated development of ecology and economy and society, and can provide a scientific reference for the integrated and optimized spatial layout of Marine protected areas.
