For the past few weeks, five planes have been spraying green, sticky hydromulch over 630 acres of the highest slopes burned during the blaze. Cheva Heck with the Forest Service says the material is almost like paper mache.
"The mulch is wet and it looks like clumps of wood and newspaper. You can actually see the little pieces of paper in it."
She says the mulch is delicate and can easily be damaged by people walking on it…so they’re asking hikers to avoid trails in the area at least until spring.
"This is a very costly treatment, it’s a state of the art treatment to try to stabilize the hillsides in the burn area and we’re really asking people to stay out to help the treatment be effective."
The aerial mulching is part of a nearly $3 million effort to address urgent post-fire needs following the blaze that destroyed 254 homes this past summer.
