BILBI indicators portal

The BILBI indicators portal is an interface where users can explore CSIRO's biodiversity indicators for any signatory countries of the United Nations Convention on Biological Diversity (CBD), plus USA. CSIRO’s global biodiversity indicators (BHI, BERI and PARC) enable governments and organisations to plan and track progress towards biodiversity goals. These indicators are all recognised as component indicators in the CBD Kunming-Montreal Global Biodiversity Framework and provide high-resolution coverage of a large proportion of Earth’s biodiversity across the entire land surface of the planet.\n\nThe Biodiversity Habitat Index (BHI) represents the proportion of biodiversity retained within a given area (such as a country or an ecoregion) in relation to the degree of habitat loss, degradation and fragmentation experienced.\n\nThe Bioclimatic Ecosystem Resilience Index (BERI) measures the capacity of landscapes to retain species diversity in the face of climate change, as a function of the area, connectivity and integrity of natural ecosystems across those landscapes.\n\nThe Protected Area Representativeness and Connectedness Indices (PARC) represent the diversity of biological communities within a protected area system, as well as how connected protected areas are within the broader landscape.\n\nThis portal provides a country-level overview of CSIRO's biodiversity indices with a link to download indicator values for countries as well as biomes within countries. More information can be found at https://research.csiro.au/macroecologicalmodelling/bilbi .\nLineage: There are 3 indicators available via this interface: BHI, BERI, and PARC. All of these indicators are derived using CSIRO's BILBI biodiversity modeling infrastructure (Biogeographic modelling Infrastructure for Large-scale Biodiversity Indicators). BILBI operates on a global 30-second grid and integrates terrain-adjusted climate data from WorldClim (www.WorldClim.org, v1) and soil data from SoilGrids (www.SoilGrids.org, v1), alongside biodiversity records for more than 400,000 plant, vertebrate and invertebrate species from the Global Biodiversity Information Facility (GBIF). Spatial biodiversity models are generated using generalized dissimilarity modelling for each WWF biome/realm combination.\n\nFor BHI and BERI, habitat condition is assessed using downscaled Land Use Harmonisation surfaces, which combine land cover data from the ESA Land Cover Climate Change Initiative (www.esa-landcover-cci.org/) and coefficients from the PREDICTS database (www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html).\n\nThe PARC-representativeness Indicator additionally incorporates protected area data from the World Database on Protected Areas (www.iucn.org/theme/protected-areas/our-work/world-database-protected-areas).

BILBI指标门户（BILBI Indicators Portal）是一款用户界面，支持用户查询澳大利亚联邦科学与工业研究组织（CSIRO）针对《生物多样性公约》（Convention on Biological Diversity, CBD）所有签约国及美国的生物多样性指标。CSIRO的全球生物多样性指标（BHI、BERI与PARC）可助力各国政府与相关机构规划并追踪生物多样性目标的实现进度。上述指标均被纳入《昆明-蒙特利尔全球生物多样性框架》（Kunming-Montreal Global Biodiversity Framework）的组成指标范畴，可高分辨率覆盖全球陆地表面绝大多数区域的生物多样性。

生物多样性栖息地指数（BHI, Biodiversity Habitat Index）用于表征给定区域（如国家或生态区）内保留的生物多样性比例，该比例与该区域经历的栖息地丧失、退化及破碎化程度直接相关。

生物气候生态系统韧性指数（BERI, Bioclimatic Ecosystem Resilience Index）以相关景观内自然生态系统的面积、连通性与完整性为依据，衡量景观在气候变化背景下保留物种多样性的能力。

保护区代表性与连通性指数（PARC, Protected Area Representativeness and Connectedness Indices）既表征保护区系统内生物群落的多样性水平，也反映保护区在更广泛景观中的连通程度。

该门户提供CSIRO生物多样性指数的国家级概览，并附带下载链接，支持下载各国及各国境内生物群区的指标数值。更多信息可访问https://research.csiro.au/macroecologicalmodelling/bilbi。

指标谱系：本界面共提供三类指标：BHI、BERI与PARC。所有指标均基于CSIRO开发的BILBI大型生物多样性指标生物地理建模基础设施（Biogeographic modelling Infrastructure for Large-scale Biodiversity Indicators）生成。BILBI基于全球30秒分辨率网格运行，整合了来自WorldClim（www.WorldClim.org，v1）的地形校正气候数据、SoilGrids（www.SoilGrids.org，v1）的土壤数据，以及来自全球生物多样性信息设施（GBIF, Global Biodiversity Information Facility）的超40万种植物、脊椎动物与无脊椎动物物种的生物多样性记录。空间生物多样性模型采用广义相异性建模（generalized dissimilarity modelling），针对世界自然基金会（WWF）的每个生物群区/生物群系组合分别生成。

针对BHI与BERI，栖息地状况评估采用降尺度后的土地利用协调化表面数据，该数据集整合了欧洲空间局土地覆盖气候变化倡议（ESA Land Cover Climate Change Initiative, www.esa-landcover-cci.org/）的土地覆盖数据，以及PREDICTS数据库（www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html）的相关系数。

PARC-代表性指标额外纳入了世界保护区数据库（www.iucn.org/theme/protected-areas/our-work/world-database-protected-areas）的保护区数据。
