Because Lanzarote is so dry plants take a long time to establish themselves in the landscape after the eruptions. The first colonist is white lichen. This in turn attracts tiny bugs and then birds that feed on them. The nitrates in the bird poo allow coloured lichens to develop. Lizards are also attracted and their droppings can contain seeds making a perfect package to germinate when rain arrives. It is a wonderful and inspiring testament to the tenacity of nature in the most challenging of conditions.
