Our roads and highways cross your lands. Highway corridors connect us all for our commerce, recreational travel, workday commute, and more. The mobility and safety provided by U.S. highways is a proud accomplishment of the Federal Highway Administration and its State and local partners. The same highways that move people and products are blamed for moving invasive species. Some research supports this claim. Because of increased commerce, human habits, well-traveled tires, wind gusts and runoff, we intuitively know that weed seeds move to and from highway corridors with added speed. Over the years, highway managers discovered that their own construction and maintenance activities unwittingly exacerbated the spread of invasives. Consequently, Best Management Plans (BMP) were adopted nationwide. But what happens on the other side of the right-of-way fence is outside roadside managers' control. Private landowners and public land managers control or rail to control invasive plants on their side of the fence. The weed seed source does not always originate on the highway side. Weeds move both directions. Working with our neighbors through increased awareness and partnerships has become a sign of the times. A resources diminish, and weed populations escalate, no land manager has any other choice. When Executive Order 13112 was signed in 1999, all federal agencies and others developing federally-funded projects were asked to cooperate and coordinate on the invasive plant issue.
