Way Kambas NP is divided into 3 sub-sections.  When SIES first started its reforestation projects in Bungur sub-section (constituting 30% of Way Kambas NP - 300 sq km), the area was severely degraded from regular burning over many years and mostly imperata grass of minimal ecological value. 
Historically it provided a healthy tiger habitat with forest, swamps and rivers, supporting a large population of Sambar deer and other prey species. Way Pegadungan provides a river boundary, protecting both humans and tigers. Intense protection is needed on this side of the Park as it has been subject to ongoing fire-setting, illegal buffalo grazing and deer poaching.
