Woodpecker species, inhabiting the rocky and grassy hills of South Africa, and the Andean flicker is another. The Swiss Ornithological Institute has set up a monitoring program to record breeding populations of woodland birds. This has shown that deadwood is an important habitat requirement for the black woodpecker, great spotted woodpecker, middle spotted woodpecker, lesser spotted woodpecker, European green woodpecker and Eurasian three-toed woodpecker.

During this period, the amount of deadwood in the forest increased and the range of the white-backed woodpecker enlarged as it extended
