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.

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…)

What is a Botanic Garden?

When I’m out and about outside work, and people ask what I do, and I tell them I work in a Botanic Garden, the most common next question is, what IS a Botanic Garden? I answer my stock response, a museum with living exhibits, but this reply just scratches the surface of what a Botanic Garden really is in the 21st century.

The more accurate answer to this question is that a Botanic Garden is many things, we are at our core a living museum, a curated collection of significant species; but surrounding this core are layers that create a life and vibrancy, each as important as each other. (more…)
