Lichens Quotes

“Time passes, and as the hot midday sun and cool mountain nights alternately bake and freeze the blackened landscape of Vesuvius, something remarkable happens. Gradually, the streams of cold lava are colonized by a lichen, stereocaulon vesuvianim. This lichen is so tiny that it is almost invisible to the naked eye, but as it grows, it turns the lava from black to silvery gray. Where the lichen has gone, other plants can follow- first mugwort, valerian, and Mediterranean scrub, but later ilex and birch trees, along with dozens of species of apricot. Meanwhile, the clinkers and ash that covered the landscape like so much grubby gray snow are slowly, inexorably, working their way into the fields and the vineyards, crumbling as they do so, adding their richness to the thick black soil, and an incomparable flavor to tomatoes, zucchini, eggplants, fruit and all the other produce which grows there.”

“Between the disappearance of the river and its re-emegence is like a desert river valley, clearly carved by water, with rounded stones in the bottom and steep sides, but no water running. Yet here there are elm trees, one of which is huge, with a magnificent trunk festooned with mosses, lichens, polypody ferns and fungi, a rich tapestry of rainforest life. Uniquely, it grows horizontally out of the rock, many metres up the sheer wall of the ravine, a completely implausible place for a tree to grow, hanging in complete defiance of the laws of physics. I stand beneath it, neck craned in awe, looking up into the lush green profusion of its living community. It is winter, so all this greenery isn't the tree's own leaves, but photosynthesising life using it as a climbing frame. Paradoxically, in this dry river valley, everything about its grand gathering of epiphytes declares it to be a rainforest tree. It is a perfect synbol of survival against the odds.”
