2 Agenda Introduction Background
Ecosystem Structure WG objectives, plans Open discussion and wrap up

3 Introduction Roll call Meeting goals
Put Ecosystem Structure EBVs into context Discuss WG objectives and approach Initiate discussion of EBVs WikimediaCommons

4 GEO BON Organization

5 Criteria for EBVs Able to capture critical scales and dimensions of biodiversity Biological A state variable (in general) Sensitive to change Technically feasible, economically viable and sustainable in time Ecosystem agnostic (to the degree possible)

8 EBV Context

9 “Traditional EBVs” EBV class EBV candidate Co-ancestry
Genetic composition Co-ancestry Allelic diversity Breed and variety diversity Species populations Species distribution Population abundance Population structure Species traits Phenology Body mass Demographic traits Physiological traits Community composition Taxonomic diversity Species interactions Ecosystem function Net primary productivity Secondary productivity Nutrient retention Ecosystem structure Habitat structure Ecosystem extent, fragmentation Ecosystem composition

10 Working Group Objectives
Identify Ecosystem Structure EBVs Identify their attributes Define each attribute Lay out observation requirements (Science/Applications Traceability Matrix?) Convey to CEOS Summarize in publication Facilitate operationalization… Processing, utilization…

11 Allegory of Virtue (Andrea Andreani, 1585):
Approach Develop strawman, circulate Discuss via and (web) meetings Revise Iterate and converge Allegory of Virtue (Andrea Andreani, 1585): Virtue being harassed by Error, Ignorance, and Opinion

12 Draft Timeline… 1 July: EBVs and attributes identified and annotated
30 September: Attributes defined and observations identified 31 December: observation requirements (as traceability matrix?) ….. Workflows Operationalization

13 Example: Species Traits
Kissling et al 2018

14 Draft Updated EBV List…
Attributes Horizontal Structure Ecosystem extent Fragmentation Canopy cover (aka Plant Area Index—area of canopy projected onto the ground) Heterogeneity Vertical Structure Height Canopy profile (some measure of…) Complexity (e.g., Foliage Height Diversity) Other (A wastebin?) Above ground biomass Deadwood Leaf area index Composition by functional type
