Ideas for highway corridors

The Federal Highway Administration is seeking input about how to prioritize research on highway corridors and the environment (e.g vegetation, wildlife, wetlands, endangered species, brown fields, and water quality).

If you have any ideas, send them a comment.

They are interested in comments on big ideas, not proposals, before AUGUST 24, 2007.

I think we need to know more about how corridors of native plants along highways affects bees and other pollinators, including threatened insects. Also, does planting hardy native plants save money by reducing mowing and weeding costs? Do native plantings make driving a more pleasurable experience?

I’m also curious about the effect of planting native plants in highway corridors near native remnant prairies. On one hand, larger plant populations might improve the survival of plants and animal in the remnants by increasing the habitat area and expanding pollinator populations. On the other hand, planting non-local seed sources next to a prairie remnant might introduce genes into the local remnants that might reduce plant performance (growth, disease resistance, etc) and possibly hasten the demise of a plant population in the native remnant.
