  Preventing the introduction of noxious and invasive species—commonly known as weeds—is the first line of defense against their establishment.  The UFO applies Integrated Weed Management (IWM) principles and Early Detection/Rapid Response strategies to curtail damage to ecosystems by noxious weeds.

IWM utilizes a combination of control strategies which will hopefully result in the most effective control of target noxious species.  IWM methods include cultural practices, the use of biological, physical, mechanical, and manual treatments, and the selective use of herbicides.  Following the use of control measures, monitoring is conducted to determine which treatments are working, and on which species.
  Early detection and rapid response efforts increase the likelihood that invasions will be addressed successfully while populations are still localized and population levels are not beyond that which can be contained and eradicated.  Once populations are widely established, all that might be possible is the partial mitigation of negative impacts.  In addition, the costs associated with such efforts are typically far less than those of long-term invasive species management programs.

Surveying for noxious species is important and is focused on high-priority targets, such as high-risk locations, high-value resources, important pathways, and populations and species of specific concern.  More remote backcountry areas are also surveyed and monitored, although at longer intervals.
  AUTHORIZATIONS
BLM authorizations granting land use to private entities (such as rights-of-way and oil and gas permitting) always include specific stipulations that place the responsibility for weed management on the holder/proponent of the permitted activity.

CHEMICAL TREATMENTS
Weeds can be controlled through various levels of treatment.  Should chemical methods (herbicide treatments) be selected, the BLM requires both prior approval to conduct chemical weed treatments and follow-up recording of the actual application of the herbicide(s).  Contact the BLM UFO Weed Coordinator directly for additional guidance should biological control methods be proposed.
