Nature Needs Half…but which half?

Mapping forest biodiversity signficance
Stuart Butchart, BirdLife International
Manages the World Database on Key Biodiversity Areas – information on 15,000 of the most important sites for nature on the planet
Manages the IUCN Red List– information on the extinction risk of 80,000 species
Manages the World Database on Protected Areas– information on 200,000 protected areas
Developed the PREDICTS model- Based on a global database of terrestrial species' responses to human pressures
Developed work on revised ecoregions and their protection status, & landscape priorities for charismatic species (tiger and apes)
Global Forest Watch Biodiversity
Why integrate tree cover & loss with other biodiversity datasets?
Reassessed the status of 11,000 forest-dependent vertebrates
Quantified threats to the largest biodiversity site network in the world

Richness of species with small distributions
Each cell scored for its aggregate contribution to the distributions of all species occurring in the cell

Biodiversity importance of remaining forest (2012)
Biodiversity importance of remaining forest (2012)
Biodiversity importance of lost forest (2000-2012)
Biodiversity importance of lost forest (2000-2012)
Methods• Bird, mammal and amphibian forest species ranges from BirdLife & IUCN
• Refined ranges by altitudinal limits
• Calculated areas of tree cover in each species range for 2000 and 2012
• Weighted each range as inverse of area of tree cover
• Summed weighted species ranges to create importance layers for 2000 and 2012
• Mapped remaining tree cover in 2012 using importance layer for 2012
• Mapped tree cover loss 2000-2012 using importance layer for 2000
• In future, add other taxonomic groups (e.g. reptiles, conifers, cycads, rattans,
gingers, monarchs and swallowtails by 2020)
What does it tell you?• Which areas of forest loss represent the most significant losses of forest biodiversity
(in terms of their aggregate contributions to species distributions)
• Which areas of remaining forest are the most significant for biodiversity (in terms of
their contributions to species distributions)
How might it be used?• Filtering GLAD alerts
• Informing land-use planning decisions
• Prioritising protected area expansion
• Targeting investments in forest conservation
• Screening potential business operations

Short-term goals:
Refine modelsRefine mapsExtend to global area
Biodiversity Intactness
What does it tell you?• How native species assemblages are impacted by:
• forest change (including regeneration) • the use of cleared areas of forest (i.e. is the area used for
agriculture, urbanisation etc.)• other human pressures (e.g. the introduction of roads)
• Where we can find areas of: intact biodiversity, recovery, and dramatic degradation
How might it be used?• Gathering statistics (at regional to national levels) on progress
towards retaining biodiversity*• Advise land-use planners and businesses on:
• the consequences of development to biodiversity• where development would be most harmful to biodiversity
• Advise protected-area planners on hotspots of intactness• Filtering GLAD alerts
* for instance, the BII was already used as an indicator in the 2016 UK State of Nature Report

• Who could use these data? How do we reach them?• What can these data be used to accomplish?• What will be the main challenges we will face?• Other than a map, how can we display data so it is best understood? How do we best
communicate these data and insights?• In an ideal world, what would GFWB look like in one year? Five years? Ten years?
