In Iceland, in July, the landscape in many places is carpeted in blue. The fields of lupines (Lupinus nootkatensis) are almost impossibly beautiful*, and lupines are adored by tourists and by many Icelanders, too. But they’re not an Icelandic plant; they’re introduced and invasive. Thereby hangs a tale, and a conundrum for conservation biology.
I normally despise invasive species, as most ecologists do, but I have a lot of trouble hating lupines. Again and again I find myself smiling at a field of blue, and then catching myself with a start as I remember that they aren’t supposed to be here. I’ve had this reaction in Iceland, in New Zealand, and in my home of eastern Canada (and here’s a nice piece from Amy Parachnowitsch admitting to the same reaction in Sweden).
These beautiful lupines make obvious a serious problem in our efforts at nature conservation. It’s not a problem with conservation biology (which is the science of how to effect conservation, once we’ve decided to). It’s a problem of motivating conservation, and I think a deep philosophical one. That problem: why should we conserve natural ecosystems in the first place? Continue reading
