[en] Several studies have demonstrated the importance of forest structure on forest bird
species richness. The objective of the present study was to determine the importance
of forest structure on forest bird richness in Denmark. For this purpose three
components of the forests were taken into account; tree height, type (coniferous or
deciduous) and canopy cover. These three data sets were linked to data from a bird
census carried out by volunteers throughout Denmark and different statistical analyses
were performed. The results of the statistical analyses highlighted the importance of
canopy cover when considered within a 500 meters buffer zone. The statistical
analyses also showed that the percentage of forest is a significant factor explaining
the richness of forest birds. If a certain threshold of percentage of forest is reached,
then trees measuring over 17 meters are also considered as factors positively
influencing forest bird richness. At the species level, whether the forests are dominated
by conifers or deciduous trees does not affect richness, the key factor being the
proportion of forest. However, it is clear that other factors that were not taken into
account in the analyses conducted in this thesis are likely to influence forest bird
richness in Denmark. Another limitation of this study is that the data used in the
analyses are from different years and sources.
