Upper Extent of Light Infestations:
Control: Hand cut-stump control work with bio-control (if proven effective in SE CO) for remaining tamarisk.
Biomass: Stack for wildlife where hand cut-stump control is used. Leave standing where bio-control (if proven effective in SE CO) is used. Stack and burn slash piles when conditions permit.
Restoration: Natural Restoration.
Lower, Heavy Infestations at Tributaries’ Confluence with the Purgatoire River:
Control: Mostly bio-control for tamarisk control with some hand cut-stump work around stands of valuable vegetation.
Biomass: Stack for wildlife where hand cut-stump work is performed. Leave standing following bio-control (if proven effective in SE CO). Stack and burn slash piles when conditions permit.
