Doug Tallamy is one of my heroes. He is a visionary thinker with the ability to tie together disparate bits of information — research results, personal observations, known scientific facts — into powerful calls for action that guide us toward living within nature, rather than continuing to segregate ourselves from it.
He is also a stimulating speaker who fills the brain with ideas and the heart with hope.
Here’s a recent video of Professor Tallamy discussing, among other things, how we can create nature corridors where it wouldn’t interfere with human use of land, to restore and protect diminishing populations of plants and animals trapped in isolated fragments of habitat such as parks, preserves, and residential yards.
Many species of animals and plants cannot adapt as quickly as needed to the changes in our landscapes (due to human development) and our climate, so they run the risk of extinction. Humans can boost those populations by creating or preserving corridors that allow those species to move through human-dominated territory in order to find food and mates.
Tallamy suggests several types of land that aren’t suitable for human use and could become nature corridors : mountain ridgetops, land alongside rivers & streams, highway shoulders, and cuts for power lines.
He isn’t the only one thinking about this strategy. The U.S. federal government recently unveiled a proposed monarch butterfly corridor to be created down the middle of the country along Interstate 35. It would, of course, benefit other pollinators as well.
One key to creating successful nature corridors will be addressing their inevitable intersections with roads. The extremely new field of “road ecology” explores ways in which animals can coexist with roads. For example, wildlife bridges (many of them still conceptual at this point) can help larger and more earth-bound animals move safely across roads. Or, in the case of toads, under them.
