A new series of Landsat images begins in 1990, where it shows the relatively undisturbed natural forest in the area that would become the national park. In following years.
Landsat imagery shows a loss of natural forest in the park area and surrounding forest logging concessions. The logged areas initially appear brown or red, but take on a green color as the palm plantations which replace the original forest mature.
Though the replanted areas appear similar to the natural forest in Landsat imagery, they no longer support the original diversity of animal species.

Safeguarding freshwater resources is crucial, and while scientists use a variety of ground-based techniques to gauge water quality, the Landsat program has provided water quality data from orbit for decades.
