1 Towards a global map of Roadless Areas

2 OUTLINE Institution Topic Study Area Data Buffer Tools

3 INSTITUTION CEEB - Centre for Econics and Ecosystem Management ROADLESS AREA INITIATIVE SCB - Policy Committee of the Europe Section of the Society of Conservation Biology 1

4 ROADS Threat to Biodiversity and ecosystems Direct impacts Habitat fragmentation and isolation alteration of sites dust + salt heavy metal pollution noise animal mortality caused by vehicle collision Indirect impacts restrict gene flow reduce landscape connectivity alter species behaviour change species composition ROADLESS Conserving native biodiversity and ecosystem services Cost efficient and effective way to protect biodiversity 2

5 STUDY AREA 3

6 DATA OpenStreetMap (OSM) Data Purchased by Geofabrik on Nov. 14 th 2013 Only roads in.shp file format Road categories Road categories Description Major roads motorways/ freeways, important roads, primary roads, secondary and tertiary roads Minor roads smaller local roads, roads in residential areas, streets were pedestrians have priority and pedestrian streets Link Roads that connect from one road to another of the same or lower category Small roads service roads buildings, parking lots, for agricultural use, in forest, often gravel roads Paths (unsuitable for cars) path for horse riding, cycling, and footpath unspecified path Other unknown type of roads 4

8 BUFFER 1 KM For all road categories a 1 km buffer was created (no distinction has been made) General global overview 5

9 ArcMap Tool 6

10 ArcMap Tool Continent Roads + Buffer Roadless Area Patches 7

11 DISCUSSION Data limitations Incomplete Might be false Ground truthing was not conducted Software limitations Large datasets Shapefile size limit GDB Simplification of data Helmholtz Centre for Environmental Research UFZ in Leipzig Multiple Arc Map Threads High capacity computers / Servers 11

12 OUTLOOK Finishing the global analysis Ground truthing of OSM Data Evaluation of Roadless Areas Datasets on deforestation, biomes 12
