Take a look at what exactly the Army Natural Resources Program is doing. http://manoa.hawaii.edu/hpicesu/dpw.htm. They not only work on Army lands, but on State, BWS lands as well to protect forest Habitats and prevent endangered plants, tree snails, insects and birds from going extinct. The military has a very negative track record but this project is moving forward and has since the 90's. I have noticed our native forests rapidly disappearing (the silent invasion that's going on behind everyone's backyard that nobody realizes) on Oahu due to feral pigs, goats and invasive weeds all over the island. What other major land owners are restoring forest? Kamehameha Schools (Kalihi/Punaluu)? nope. State land? barely: only a few Natural Area Reserves. Morman Church(Laie)? nope. BWS? nope. Of course it would be beneficial if the military would go elsewhere altogether, not just "downsizing", but for now these conservation programs and partnerships are doing great work in my opinion
