Conclusions & Implications

Shoulder (erosion) is the largest portion in the PPA
The PPA does not include topographical linkages, except summits
Lowland topography has to be reconsidered….
![Page 24: Russia China - IAIA20...North Korea Russia Japan South Korea (8/24) Key Ecological Linkage: 백두대간Protected area (PPA) 0 150 300 Kilometers China North Korea Russia Japan South](https://reader033.vdocuments.site/reader033/viewer/2022043023/5f3f37caea751f7ac51e6903/html5/thumbnails/24.jpg)
(24/24)
Extend the PPA to include the topographical linkages…
Include topographical linkages to conserve biodiversity in the forests
Support the sustainability of forest ecosystem from climate change
