Intact Forest Landscape Methodology and Definitions What is an Intact IFL Degradation Forest Land cape (IFL)? An unbroken expanse of natural ecosystems (both forests Fragmentation and non forests) within the zone of current global forest extent, IFL area may be divided into smaller forest fragments by roads and other infrastructure showing no signs of significant human activity and large enough that all native biodiversity, includingviable populations of wide-ranging species, could be maintained Tree Cover Loss > 2 k Gross forest cover loss can be caused by clear-cuts, agriculture clearing, selective logging, m settlement expansion, fires and mining > 500 km2 m k 0 1 > 2 1 LARGER THAN 500 KM 2 AT LEAST 10 KM WIDE AT THE BROADEST PLACE 3 AT LEAST 2 KM WIDE IN CORRIDORS OR APPENDAGES COMPONENTS OF FOREST LANDSCAPE INFRASTRUCTURE CORRIDORS FIRES NATURAL DISTURBANCES Infrastructure (e.g. roads, Small IFL appendages and Burned areas were Natural disturbances navigable rivers, pipelines, narrow corridors less than considered degradation (windstorms, insect infestation, NDS SHR LA U etc.) was buffered by 1 km 2 km in wide were c sidered only if they were connected diseases) were not considered S BL AS A and considered degraded degraded to infrastructure IFL degradation R N G D FOREST OPEN AND CLOSED Degradation Analysis Results S S P K M C A O R W S DEGRADED/ REMAINING FRAGMENTED NON MANAGED IFL FOREST FOREST FOREST L AK RS ES AND RIVE Source: P.
