TR-07 RECLAMATION PLAN work. It requires both a high density weed population and a suitable habitat for the control organism to survive the winter. If conditions are proper, this approach is definitely preferred to spraying vast areas with herbicide and probably killing large numbers of other plant species that should not be killed because they serve a vital role in the ecosystem. Biological control will rarely destabilize an ecosystem, but herbicide control often creates large holes in the ecosystem that are sometimes filled by species that are no more desirable than the weeds or, in some cases, even more problematic than the noxious weeds that needed to be controlled.) 4. Weed Control Goals: The highest priority weeds are those species that are uncommon or rare on the site. On affected lands, the common,well established noxious weeds (such as Leafy Spurge) has a lower priority. The spurge is there to stay, but the new entries must be stopped before they become like the spurge. New Noxious Weed Introductions - Complete Eradication is mandatory Other species already present(applies to affected land only): Leafy Spurge - Population reduction to 75% or more of the initial population. Canada Thistle - Prevention and eradication of new colonies on affected lands. Knapweed - Eradication. Tumbleweeds - Control only if the population threatens revegetation success. New Entries - Eradication. REQUIREMENT 28: No grazing, other than by native animal species, will occur on land being revegetated until such time as it is determined that grazing may occur without causing damage to the new vegetation. (TR-07 Note: A new grazing lessee will now be instituting grazing using a highly managed approach. Overgrazing of reclaimed areas may not be such a severe hazard as it was previously, so this requirement may not actually be necessary.) Discussion: Rule 3.1.10(4) of the Minerals Rules and Regulations of The Colorado Mined Land Reclamation Board for the Extraction of Construction Materials states that"The Board or Office, in consultation with the Landowner and the local Soil Conservation District, if any, shall determine when grazing may start."This control can be implemented by means of electric fencing,barbed wire fencing, or simply keeping cattle, sheep, goats, horses or other domestic livestock from utilizing the reclaimed land. The operator, the grazing lessee, if any, and the landowner will cooperate fully with each other to insure that grazing does not occur until it is determined that it can occur. (For maps see Exhibit F: Plans for all upland and lowland areas no longer in the lease have been deleted as a part of TR-07. Exhibit F now includes only lands in the new lease.)
