Abstract

The occurrence of woodpeckers in European forests depends on many forest stand characteristics. During the study conducted in 2013 in the agricultural landscape of SE Poland (in an extremely deforested area with a 5% share of forest area), the habitat requirements of Middle Spotted Woodpecker Dendrocoptes medius, Great Spotted Woodpecker Dendrocopos major and Syrian Woodpecker Dendrocopos syriacus were described. For this purpose, the degree of occupation by individual species of 73 forest patches was assessed over an area of 355 km2. To determine the habitat requirements of the woodpecker species, a set of 7 parameters characterizing the studied forests and their surroundings were determined, viz. forest patch area, average age of the tree stand, etc.). Generally, the Syrian Woodpecker inhabited small forest patches surrounded by a significantly larger proportion (2.3–5.6%) of orchards, compared to forests uninhabited by this species. The most important factors that positively influenced the occurrence of the Middle and Great Spotted Woodpeckers were the forest patch size, average age of the forest patch stand, and area of forest stands aged older than 80 years. The Great Spotted Woodpecker preferred forest patches with an area exceeding 15 ha, but the Middle Spotted Woodpecker occurred only in forest patches over 42 ha. Such minimum forest patch areas should be considered essential for protecting the two mentioned species in a heavily deforested landscape. Small-sized forest patches should also be protected, enabling refuge for the Syrian Woodpecker. Keywords: bird conservation strategy, forest management, habitat selection, primary cavity nesters, rural landscape, woods, woodpeckers, SE Poland

波兰东南部农业景观中三种共存啄木鸟对森林特征的要求

啄木鸟在欧洲森林中的出现取决于许多林分特征。在2013年对波兰东南部农业景观进行的研究中（在一个森林面积占5%的极度砍伐地区），描述了中斑啄木鸟Dendrocoptes medius、大斑啄木树Dendrocopos major和叙利亚啄木鸟Dendrocopos syracus的栖息地需求。为此，对355个面积内73个森林斑块的单个物种的占用程度进行了评估 km2。为了确定啄木鸟物种的栖息地需求，确定了一组表征所研究森林及其周围环境的7个参数，即森林斑块面积、林分的平均年龄等。一般来说，叙利亚啄木鸟居住在被明显更大比例（2.3-5.6%）果园包围的小森林斑块中，与该物种无人居住的森林相比。对中斑和大斑啄木鸟发生有积极影响的最重要因素是斑块大小、斑块林分的平均年龄和年龄超过80岁的林分面积。斑点啄木鸟喜欢面积超过15的森林斑块 哈，但中斑啄木鸟只出现在42岁以上的森林里 哈这种最小的森林斑块面积应被视为在严重砍伐的景观中保护上述两个物种的必要条件。小型林地也应得到保护，为叙利亚啄木鸟提供庇护。关键词：鸟类保护战略、森林管理、栖息地选择、原生穴巢鸟、乡村景观、树林、啄木鸟、波兰东南部

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
