Distribution and habitat of the Middle Spotted Woodpecker (Dendrocopos medius) in Belgium.
A survey of the distribution of the Middle Spotted Woodpecker in Belgium was undertaken by the Centrale Ornithologique Aves. The number of occupied breeding territories is estimated at between 530 and 650. The tendancies of geographic and numbers progression have been ascertained. Three approaches to habitat confirm the restrictive character of the Middle Spotted Woodpecker, confined to large oak trees with a preference for stands with a relatively high trophic level. The ageing of oakwoods generally and mortality are suggested as being decisive for bird's present expansion. Attention is drawn, however, to the probability of a future decline, not only because of the high rate of dying oaks but also because of a lack of young oak stands, and the phenomenon of splitting op going hand in hand with a possible reduction of habitats. A few lines outline research for better definition and the underpining of conservation measures
