In Defense of Plants

 "In Defense of Plants" is the title of a fairly new blog site that has come to my attention.  It is written by Matt Candeias. The blog postings are thoughtful, informative, and always interesting.  The photography is excellent.  It is very encouraging to see members of the newest generation of thinking adults (what do we call them - millennials?) take a passionate and informed interest in plants.  Hopefully Matt will maintain this effort for many decades to come.  I'm putting it on my favorites list, and I hope you will too.
The following excerpts are from an article Matt did for the online magazine "The Wildernist,"  edited by John Jacobi:
"Towards the end of my undergraduate career I took a job restoring abandoned quarries throughout western New York. The goal was to take possibly the most destructive form of land use and attempt to coax something resembling a habitat out of it.
My favorite project took place in an old sand pit way out in the country. Spending time there was rewarding enough, as the surrounding wilderness was already beginning to reclaim what humans had taken from it. We were attempting to reintroduce an endangered butterfly to part of its former range, and to do so, we needed to establish a robust population of its host plant. The butterfly in question is the Karner blue (Lycaeides melissa samuelis) and its host plant the blue lupine (Lupinus perennis). Karner blue caterpillars feed on nothing else.
The Karner Butterfly
Following the end of the Pleistocene, L. perennis took advantage of the well-drained soils left in the wake of the retreating glacial ice sheets and spread from coastal New England all the way to Minnesota. It specializes on nutrient poor, sandy soils. In fact, these plants were once thought to be bad for the land, robbing it of life and vitality. As such, they were maligned. The generic name “Lupinus” has its roots in another Latin word and was given to these plants because early botanists associated them with another creature that haunted their nightmares and left the land impoverished—the wolf (Canis lupis). As with the misappropriated hatred towards the wolf, the idea that Lupine was bad for the land was far from true. Being a legume, it is able to fix atmospheric nitrogen, thus bringing life to barren soils. But, as is human nature, facts never seem to trump emotions, and L. perennis has seen a 90% decrease in its numbers in the wild. With it went the Karner blue butterfly."
".... plants have this amazing ability to absorb energy from our sun and turn it into food, a fact that with the exception of deep sea thermal vents, every organism on this planet relies on in one form or another. They have been at it for a long time too. The botanical world is full of survivors. Far from being boring and nonreactive, plants are living, breathing organisms capable of some amazing biological feats, which include chemical warfare that the UN would seriously frown upon. They have been at this whole survival game for much longer than any of our ancestors have. Each species has its own story, its own ecology, and its own way of interacting with the world around it. Plants aren’t here for us. We are here because of them. Everything is. We define entire ecosystems by the types of plants that grow there. We simply cannot understand the living world without first considering the flora that shaped it."
