Lichen through the looking glass

I’ve recently started noticing lichen. Now I can’t stop noticing it; it’s everywhere, living on, and in multiple surfaces. Walking around Bristol it’s on the harbour walls, the loch gates, on holiday it’s on the rocks of the cliffs and hanging from trees. Lichen covers around 8% of the planet’s surface area, and so could be argued that it’s one of the most successful collaborations in the natural world.  When you do start noticing, you want to keep noticing, and get in closer with a little hand lens, a looking glass.

Tipping Point; the fire in the garden.

Fire has become a terrifying normality for many people around the world; a natural inclination for us here in the UK is to watch from afar and be thankful it isn’t happening to us. We all do it, look at the hurricanes, tornados, and fires with a furrowing of our brows and concern but deep down the safety for ourselves is at our core. In Tipping Point, an installation by Luke Jerram in early October this year, visitors were plunged into the reality of communities abroad by creating a simulation of a forest fire right here in the Botanic Garden.

And we owe it all to leaves.

In summer a breeze will work its way through the boughs of a tree and the resulting sound is one of the constants in our lives, a white noise of leaves dancing on their stems. Right now, in autumn the leaves are at our feet, or swirling around corners, collecting at the foot of a tree, or at the base of a wall. Leaves stimulate all of our senses; we calm down merely by touching a leaf due to our innate evolutionary programming, and the sight of them emerging in Spring is enough to quicken our heartbeat. When we give leaves a bit of thought, it’s a wonder every tree and shrub doesn’t have a group of people staring up at them in awe. (more…)

Survival of the… ?

‘Survival of the fittest’ is a phrase used to describe the natural world; the spoils are to be won and the strongest live on. Life is more complicated than this, and there are many lives that endure through building partnerships and being good neighbours. New discoveries are being made all the time about the adaptations that organisms make to survive. Many of these discoveries are in the plant world; our understanding of reciprocal relationships between plants, animals and fungi is growing all the time and perhaps the natural world is more companionable than we originally thought. There are brutal elements, but all the while connections are being made, trades agreed, and reciprocal back scratching develops, aka ecological mutualism.
