Building Green’s intrepid survey squad spent last weekend under the terraces at Madeira Drive. Armed with clipboards and Bob the Builder hats, we surveyed the extent and health of the green wall, and updated the list of plants and other wildlife found there.
The results are in. Ton up! We have now broken the 100 species barrier…104 species of plant to be exact…and found a number of other wildlife using the wall that we hadn’t seen before. We counted 117 trunks of 150 year old Japanese Spindle – not including the plants at Duke’s Mound further East, or those in the planters on the terrace itself.
This really strengthens the case to designate this wall a ‘local wildlife site’ in the Council’s forthcoming City Plan. It would be the only green wall site of importance for nature conservation in the UK, and deserves this recognition.
Here is the full list of species. Interesting finds include Japanese Holly Fern, shown below, Hoary Stock, and Holly Blue and Painted Lady butterflies.
Big thanks to our volunteers, and to the Council for the PPE and access.
