Avifauna along artificiel spruce (Picea abies) succession at the Plateau des Tailles (Southern Belgium).
Deceuninck, B. & Baguette, M.
This paper aims to analyse the avifauna living in the artificiel spruce succession and to comparate bird species living in spruce with those of deciduous forests. Fifty-eight bird species were recorded using a progressive sampling method (E.F.P.) in 15 spruce plantations of increasing age and two mixed beech-spruce forest. Species number was minimum in the youngest pure spruce plantation (8 species), and maximum in the multiple-aged stands as well as in the pure 37 yr spruce plantation (34 species). Youngest plantations recruited open habitat species; a fast change occured in the bushy stages (plantations from 3 to 15 yr). From stands of 31 yr, only 4 species living also in young stages were still found. Species composition is much less predictable between young stations than between older ones. A few species are typical of multiple-aged forests : Great Tit, Blue Tit and Nuthatch. The mixed 50 yr plantation was very similar to pure pruce plantation of the same age. A comparison was made between the species composition of the Vosgian beech succession studied by MULLER and those of the artificial spruce succession. It showed that young spruce stages were really net related to any other stages in both successions. Bushy stages are very similar in both successions. The avifauna of old stages diverge by (1) the arrival of coniferous forest specialsts in old spruce plantations, like Crested Tit, Goldcrest, Nutcracker, Pine Crossbill or Siskin and (2) the occurence in the beech succession of old broadleaved forest birds and (3) the scarcity of some species.
