还迫切需要在全球范围内推广监测计划以及能力建设、数据收集计划设计、质量控制和统计分析方面的发展。在不久的将来可能提供的大多数指标将基于现有的数据库和监测计划。然而，由于生物多样性最丰富的地区往往是资源最缺乏的地区，目前的数据库和监测通常不具有充分代表性，并且没有涵盖足够广泛的系统组成部分。对其他现有数据（如果分散）的荟萃分析为快速填补一些空白提供了相当大的空间（20）。另一种可能性是使用遥感来测量当前和回顾性的生物群落的范围和状况。这种方法已经很成熟，可用于测量全球森林变化 (21)。
There are also immediate needs for global extension of monitoring programs and developments in capacity building, design of data collection programs, quality control, and statistical analyses. Most indicators likely to be available in the near future will be based on existing databases and monitoring schemes. However, as the areas richest in biological diversity are often those most lacking resources, current databases and monitoring are usually not fully representative and do not cover a wide enough range of system components. Meta-analyses of other existing, if scattered, data offer considerable scope for plugging some gaps quickly (20). Another possibility is the use of remote sensing to measure both currently and retrospectively the extent and condition of biomes. This approach is already well developed for measuring changes globally in forests (21).
