References on weeds associated with logging and other activities

The spread of exotic weeds is one of the uncounted costs of human disturbance whether the result of logging in the name of stewardship logging, salvage logging (post fire logging) or forest thinning, as well as other abuses like livestock grazing, ORV use, and sprawl. Almost no government agencies consider the real cost of invasive species spread when they approve these activities and in the long run the cost of in terms of ecosystem modification and control of exotics often vastly exceeds any benefits that are derived from logging, grazing or new subdivisions. All of you are involved in these issues to some degree or another and might find this annotated reference review I just came across by NRDC of some use or interest. www.nrdc.org/land/forests/roads/chap4.asp
