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

 

Light Infestations:
Control: Mechanical extraction or grab and cut-stump control for high priority areas. Hand cut-stump control work around valuable vegetation and in inaccessible areas. Bio-control for remaining tamarisk.
Biomass: Mulch for revegetation or stack for wildlife. Stack and burn slash piles when conditions permit.
Restoration: Pole plantings of cottonwood and willow along channel edges and tall-pot, deep planting of native shrubs and grass seed mixes for upland areas.

Moderate to Heavy Infestations:
Control: Mechanical mulching for high priority areas. Hand cut-stump control work around valuable vegetation and in inaccessible areas. Bio-control (if proven effective in SE CO) for remaining tamarisk.
BiomassV: Mulching or stack and burn slash piles when conditions permit.
Restoration: Pole plantings of cottonwood and willow along channel edges and tall-pot, deep planting of native shrubs and grass seed mixes for upland areas.


Main-stem – Moderate Infestations, Broader Floodplain:
Control: Mechanical mulching for high priority areas. Bio-control (if proven effective in SE CO) for remaining tamarisk.
Biomass: Mulching.  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, Spotty Infestations along the Tributaries:
Control: Hand cut-stump removal where appropriate around valuable vegetation. Bio-control for remaining tamarisk (if proven effective in SE CO).
Biomass: Stacking for wildlife.
Restoration: Natural revegetation
