From the La Junta Tribune-Democrat (Bette McFarren):
The object of the letter and the grant is to obtain an additional $18,000 in matching funds to continue the tamarisk eradication. The Colorado Forest Service has had good luck with Habitat, a herbicide that can be applied from the air, using a helicopter, or from an ATV. The herbicide takes 3 years to deplete all carbohydrates in the root system. Last year it became substantially more cost effective when the original patent ran out and other sources than the inventor could manufacture it. The cut-stumps method of application is less efficient in that it is extremely labor-intensive and does not leave the tree skeletons for wildlife habitat or beneficial recycling. Mulching and chipping are options to remove the remains of the tamarisk.
