Why do the trees in 343 Guilty Spark have big green blobs?

I think it has some thing to do with the flood


Hello, I am The Moniter of this instillation....

I think that the Flood testing facility is in the swamp, the structure you meet 343 Guilty Spark was the top of The Library, and the other building was the testing facility, the place wher the Flood started from I think. I is very likly that the glowing trees are from the testing. the flood also glow when the are shot, try it on a dead one. Also if you find a dead Elite with its mouth open look inside, it glows.
