Aerial Hydromulching Questions and Answers
What is hydromulch?
The hydromulch consists of wood mulch, recycled paper, water and a tackifier, which is guar gum based and binds the ingredients together. Green dye helps the pilots monitor application, but the hydromulch will turn gray after a few days on the ground.
How does hydromulching help the burned area recover?
The hydromulch hardens a few days after application and binds to the soil on the hillside to minimize soil movement. The mixture traps moisture and creates an environment in which seeds can sprout. Eventually, the new vegetation takes over its natural role in stabilizing the soil.
