Those two images are after the US took over. I have about 10 BDA images of it under construction by the japs, and during and after bombings. The dispersals were almost entirely covered with trees except the taxiways themselves until the B-24s and Naval bombardment made it look like those 2 images you posted

The trees in question were not jungle, however. It was a coconut plantation, so even rows of single trees.
