In more recent times the process of controlled burning of the heather has taken place. The heather is burnt after 15 years of its life cycle before it becomes mature and allows colonisation of the area by other plants. The ash adds to the soil fertility and the new growth that results increase the productivity of the ecosystem and provides the sheep with a more nutritious diet than is provided by the elder heather. This controlled burning maintains a plant community which is not the climatic climax of the area, and is therefore a plagioclimax.[citation needed]
