About 20 months after the last update (December 30, 2021), I again visited the same location and checked on the pace of expansion of the Imperata cylindrica cluster.
The cogon grass cluster had been expanding at a rate of 0.6 meters per month to one side, and during the last check, it had moved 6 meters to the west (left) of a green optic cable marker (see pic below).
When I visited yesterday, the cluster had expanded laterally another 6 meters before encountering a large low lying tree (see pic below).

The cogon ramets had crowded to the right of the crown of the low lying tree, but has not yet been able to bridge the shadow gap and cross to the other side.
However, I found isolated ramets huddling under the tree's shadow, with the one furthest west about 3 meters in from the crown edge. In addition, the cogon cluster is at the same time growing around the tree from behind. The result of these two activities means that sooner or later, the cogon will make its way to the unshadowed west side of the tree. at which point it should again commence its rapid lateral movement.
