it's made of . . . ?

For a few weeks now, I've noticed that some of the burned swatches of Griffith Park, which I pass on my commute, have had some sort of bright green colored stuff spread on them. Last week I actually witnessed a helicopter dumping a load of green onto a slope. Just after dumping, the helicopter seemed to stand straight up on its nose for a moment -- from the sudden unbalancing? -- which I hadn't seen a helicopter do before. I was relieved to see it quickly right itself and putter off westward.

I wonder what the green stuff is. Something to attempt erosion control for the rainy season, I'm guessing, maybe like this.

The green material you refer to is generically called Hydromulch. It is a product manufactured to be a seed-bed to support seed by acting like a soil covering that typically protects seedlings from UV Rays, birds, and drying out. In the past, the only materials available for use in hydromulches were recycled paper and wood (wood being best), but now cotton gin waste is used. Gin waste acts as a fertilizer and is the best choice amoung these materials. For more info see this link
