“…However, to our knowledge, there are no quantitative models describing relationships between densities and habitat parameters for this species. In our study area, both woodpecker species reached very high densities in both pre-outbreak and outbreak periods compared to other forest stands (Michalek and Miettinen 2003;Pasinelli 2003;Kosiński and Winiecki 2005;Wesołowski et al 2015). This suggests that the availability of suitable nest sites does not limit the abundance of either woodpecker species in mature riverine forests.…”

“…Taken together, these studies suggest that the amount of standing dead wood does not affect the abundance of great spotted and middle spotted woodpeckers, irrespective of the spatial scale. On a habitat and landscape scale, middle spotted woodpecker abundance (and density) increases along with the growing number of large living trees and the share of old growth stands (Kosiński and Winiecki 2005;Stachura-Skierczyńska and Kosiński 2016). The most likely mechanism that permits Study period-outbreak 9 Dbh -0.…”

Standing dead trees may be a limited resource for woodpeckers in managed forests, especially for species that rely on dead wood for their nest or roost cavity, and as foraging sites. Effective conservation strategies for woodpeckers require a detailed knowledge of species' responses to dead wood availability. To investigate the importance of standing dead wood (snags) for the abundance and nest-site use of the great spotted woodpecker Dendrocopos major and middle spotted woodpecker Leiopicus medius in mature riverine forests, we compared the responses of birds between two periods-before mass mortality, and during a pulse in standing dead trees. The density of standing dead trees available for cavity excavation by the great spotted woodpecker and the middle spotted woodpecker increased significantly during the study period: 37-fold and 4-fold, respectively. Temporal trends in the abundance of both woodpecker species from 2000 to 2015 were not significant. Great spotted woodpeckers were significantly more likely to use dead trees and places with wounds in species other than oak and ash during the outbreak period than in the pre-outbreak period. Middle spotted woodpeckers were significantly less likely to excavate cavities in tree species other than oak and ash in the outbreak period, but dead trees were more likely selected. An interspecific comparison suggests that the probability of a nest-hole having been excavated by a middle spotted woodpecker increased with a nest-hole sited in ash, in a dead tree, in a limb/branch, and decreased with 123Biodivers Conserv (2018) 27:123-145 https://doi.org/10.1007/s10531-017-1425-6 a nest-hole in a closed forest. These findings suggest that woodpecker species, especially weak excavators, may benefit from an increase in dead wood availability leading to nest niche shifts into more favorable substrates for cavity excavation. However, a strong increase in dead wood availability does not modify the general pattern of niche partitioning between great spotted and middle spotted woodpeckers. Conservation plans for the specialized middle spotted woodpecker must consider the preference for dead and decaying trees. The decreasing number of large ashes and oaks, and the lack of natural regeneration of the latter species, may negatively affect the middle spotted woodpecker in the future.

“…In addition, the species has a positive population growth across Europe (Table 4). This is a deciduous forest specialist traditionally preferring older oak stands (Kosiński & Winiecki 2005, Müller et al 2009). The absence of sufficiently large areas of suitable breeding habitat has been identified as the main cause of the species' disappearance from Sweden (Holmbring & Pettersson 1983).…”

There is presently great concern about local, regional and global loss of species. We examined those breeding species and subspecies (“species”) of birds that either established themselves or went extinct in Sweden in 1850–2009. In this period Sweden got 38 new and lost twelve breeding bird species. The average (and surprisingly steady) rate of colonization was 2.4 species per decade, which was three times higher than the rate of extinction of 0.75 species per decade. We also predict future establishments and extinctions until year 2050, based on Species Distribution Modelling and recent information from neighbouring countries. We find it probable that eleven new species will join the Swedish avifauna until 2050 and possible that another nine species will do so. The predicted rate of probable establishment is 2.9 species per decade. We identified seven species/subspecies to be at risk of extinction by 2050. The future in Sweden for several of these species is probably dependent on the success or failure of ongoing conservation programs. There seems to be no immediate threat of establishment of alien species.

“…LF, formerly called as Stare Budy (Kosiński and Winiecki 2005;Kosiński and Hybsz 2006), is an isolated forest area of 643.5 ha (630.8 ha of forest area). It is a part of the largest concentration of old oak forests (mainly Quercetea roboripetreae, locally Calamagrostis arundinaceae-Quercetum petraeae) in Poland (Krahl-Urban 1941, 1943Kasprowicz 2010).…”

Analysis of ecological time series allows to assess the relative contribution of density-dependent and density-independent factors influencing the regulation of the population of a species. In this study, we investigated whether the annual fluctuation in the population of Middle Spotted Woodpeckers Dendrocoptes medius can be attributed to the direct or delayed densitydependent regulation or to the density-independent factors such as weather conditions during the preceding winter and previous breeding season and/or disturbance in the habitat associated with sanitary felling and salvage logging of trees. This study was conducted in the Czeszewo Forest Reserve, which protects the remnants of semi-natural flood-plain forest, and in the Łówkowiec Forest, which is a managed oak-dominated stand, during 19 seasons (2001-2019). Time series diagnostic revealed that the growth rate of population of Middle Spotted Woodpecker in protected semi-natural riverine forest and in managed oak forest was determined by first-order negative feedback, suggesting an important role of direct density-dependent mortality in the regulation of an equilibrium in population size. The effect of density-dependent process varied between study sites, being lower in riverine forest, where population size has increased distinctly in recent years. In both study areas, we detected strong positive effects of wind chill temperature during the preceding winter on population growth rates. We did not find evidence for the assumption that the increase in population growth rate is affected by weather conditions in the previous breeding season and by the disturbance in the habitat associated with sanitary felling and salvage logging of trees. Our results suggest that Middle Spotted Woodpeckers can benefit from global climate warming by an enhanced rate of winter survival or an increase in the accessibility of food, e.g., insects and other arthropods. The lack of time-lag significant correlations between population fluctuations suggests local habitat conditions, e.g., forest management, can modify inter-annual variability in time series of the Middle Spotted Woodpecker.
