Control, Biomass Reduction, and Restoration Approach
For more information, please click the Problem Solutions button on the left

 

Heavy Infestations in the Floodplain:
Control: Aerial herbicide, bio-control (if proven effective in SE CO), and root plow and rake.
Biomass: Mulch, controlled burn, or stack for wildlife (if land is to be used for agriculture). Stack and burn slash piles when conditions permit.
Restoration: Pole plantings of cottonwood and willow and tall-pot, deep planting of native shrubs and grass seed mixes for upland areas.

 

Light to Moderate Infestations in the Floodplain:
Control: Hand cut-stump control, mechanical extraction, or grab and cut-stump control for high priority areas. Bio-control (if proven effective in SE CO) for remaining tamarisk.
Biomass: Mulch for restoration or stack for wildlife. Stack and burn slash piles when conditions permit.
Restoration: Pole plantings of cottonwood and willow and tall-pot, deep planting of native shrubs and grass seed mixes for upland areas.

 

Along Highways 109 and 101:
Control: Mechanical removal with grab and cut-stump or extraction. Bio-control (if proven effective in SE CO) for remaining tamarisk.
Biomass: Mulching for revegetation.  Stack and burn slash piles when conditions permit. 
Restoration: Native shrubs and grass seed mixes.
