One of the challenges to this is that we don’t have a common definition and way of monitoring, reporting, or verifying/enforcing any regulation because how we measure biodiversity varies from place to place. Traditionally, biodiversity has been measured by different biology specialists (botanists, ornithologists, mamologists, hermatologists, etc) all using their domain expertise and a concept called key stone species as indicators for true biodiversity. The truth is that biodiversity as a definition varies across scales - there is biodiversity within a population, across populations, and across species.
Second, it has taken us 20+ years to begin to make progress on carbon markets so that we can start to value carbon sequestration as a service with monetary value such that companies can converse and trade in it to show how they optimize against that metric. At present, we don’t even have a robust global map of biodiversity agreed upon across regions and specializations.
