GEO BON Coordinates Collection, management, distribution Facilitates New products and services Scope Ecosystems, Species, Genes, Ecosystem services 1. How is biodiversity changing? Why is it changing? What are the impacts? 2. 3. 6
GEO BON Example Products Trends in ecosystem services Trends in species abundance CC impact on compositional diversity CC impact on PA representativeness Indicators on the state of biodiversity What information is needed to create those products? 1. How is biodiversity changing? Why is it changing? What are the impacts? 2. 3. 7
Essential Biodiversity Variables Key variables needed to Create those products Answer those questions Primary measurements Derived variables 1. How is biodiversity changing? Why is it changing? What are the impacts? 2. 3. 8
Why are EBVs Essential? Provide inputs to products Provide guidance to Observation System What to observe 1. How is biodiversity changing? Why is it changing? What are the impacts? 2. 3. 9
Connection to Decadal Survey Both provide guidance to the Observation System Differ in scope Decadal Survey: NASA observations EBVs: All data sources, organization- neutral 1. How is biodiversity changing? Why is it changing? What are the impacts? 2. 3. 10
