  • [PDF] Global variation in woodpecker species richness

    Location Global. Methods We used spatial and non-spatial regressions to test for relationships between broad-scale woodpecker species richness and predictor variables describing current and deep-time availability of trees, current climate, Quaternary climate change, human impact, topographical heterogeneity and biogeographical region.

  • Availability of tree cavities in a sal forest of Nepal

    Abstract: Tree cavities are important structural elements of forest ecosystem that host numerous birds, mammals and other cavity-dependent organisms. Pattern of cavity distribution in temperate and boreal forests are relatively well studied, yet little is known about cavities in tropical and subtropical forests. We compared cavity availability in relation to tree condition (living tree and

  • Woodpecker cavity establishment in managed forests

    Sampling methods. Woodpecker-made tree cavities were identified during the inventory of TreMs in two groups of living trees. The tree groups were defined by current forest management schemes employed by forest managers in the study area to set aside trees from harvesting: 1) selection of up to 15 living large trees ha– 1 meant to serve, at present or in the future, as habitat trees (sensu

    Aug 06, 2017 · Aim. Globally, many bird species nest in tree cavities that are either excavated or formed through decay or damage processes. We assembled an overview of all tree‐cavity nesters (excavators and non‐excavators) in the world, analysed their geographic distribution and listed the conservation status of all species.

  • The conservation value of tree decay processes as a key

    Jun 01, 2017 · During three breeding seasons (2010–2013), we studied the cavity-nesting bird community in temperate rainforests of Chile. We found the highest reported proportion of tree cavity nesters (n = 29 species; 57%) compared to non-cavity-using birds for any forest system. Four species were excavators and 25 were secondary cavity nesters (SCNs).

Yet, the ecological relationships of cavity-nesting birds (CNBs), the main components of forest bird communities in this area, remain unknown. We examined the importance of ecological factors in 90 study plots during the breeding season to predict the probability distribution and habitat suitability of primary
