Harkoning back to Lady Bird Johnson?EUR??,,????'???s beautification project, the environmental movement is extending into highways, as over a dozen states including Colorado, Nebraska, Oregon, Texas, Tennessee, South Carolina, Vermont and Washington State have increased their number of native plantings on their interstates. The vegetation includes switchgrass, asters, amonsia, thoroughwort, and Indiangrass. Over 5,000 species of wildflowers and grasses grow adjacent Texas roads. Nebraska has limited mowing on its right-of-ways which provides habitat for wildlife, and in times of drought the grasses provide hay for cattle.
There are numerous benefits to planting with natives, such as wildflowers or prairie landscaping. It is almost always more drought resistant and resilient. Most significantly, these plants do not necessitate mowing, saving the states tens of thousands of dollars every year and eliminating the environmental impact of the mowers.
However, the movement is facing considerable opposition. Many feel that native landscaping can be a fire hazard, might impede drainage, and can interrupt highway visibility. Most importantly, some people just don?EUR??,,????'???t find the vegetation attractive. Jeanette Carey, whose husband is a state representative in Delaware, said that many neighbors complained about native landscaping on highways. ?EUR??,,????'??There was nothing but weeds in the middle of the road. It should look like a lawn mowed,?EUR??,,????'?? Ms. Carey said. Another problem is that the states differ on the type of native seeds to be used.
The fight will continue, however, as one man?EUR??,,????'???s weed is another?EUR??,,????'???s drought-resistant wildflower.
