Removing cattails is an important part of the restoration process as they slow stream flow and promote the existence of exotic crayfish.  These crayfish, among other exotic species, eat and compete with the endangered Ash Meadows Amargosa pupfish.  Overgrown cattails and reeds will be cut along Crystal Springs outflow stream channel.  Warning: you WILL get wet.  Most places the water is knee-deep.  However, in some places may be up to four feet deep.  All participants should be comfortable swimming or wading in water.
