Biosilva: conservation of biodiversity and forest management. Ecology and conservation of forest bats

Since 2001 the Department of Biodiversity of the CTFC has been working with the Servei de Protecció de Fauna, Flora i Animals de Companyia de la Generalitat de Catalunya (Service for the Protection of Flora and Fauna of the Catalan government) in studies of conservation threatened wildlife and forest management.

These studies are part of one of the basic lines of the Service on forests, biodiversity and environmental conservation.

In Europe live 34 species of bats; 28 of them breed or wintering in Catalonia (Flaquer et al. 2010). In recent decades there has been a decline in European populations of certain species (Dann 1980; Roero 1982; Gaisler et al., 1982). Until 17 species are considered threatened (endangered or vulnerable) in Catalonia. 8 of them live in forest habitats., such as Nyctalus lasiopterus and Nyctalus noctula. Part of this dynamic must be attributed to human activity caused the disappearance or alteration of diurnal roosting sites, taken by the decrease in the use of insecticides and alteration of habitats. It also is a good indicator of the conservation status of habitats. This also makes them very vulnerable to forestry activities.

Therefore, is importance to improve the applied research on the biology and ecology of the forest bats, in order to establish criteria for appropriate management and conservation tools.

The main objectives of this program are:

  1. to obtain the information necessary for the conservation of endangered species of wildlife and improve biodiversity in relation to forest management and other uses territory;
  2. aims to provide technical guidance to managers for the sustainable management of natural and model how to respond to biological diversity in future planning scenarios. The results can be translated in all cases in a series of practical manuals and guidelines aimed at managers and competent authorities on biodiversity and natural environment in order to improve the conservation status of wildlife in an integrated forest management in different forest habitats of Catalonia.

Main results:

  • Research of Endangered Species of forest bats: it has been sampled more than 300 tree cavities in different localities, and it has been localized colonies of  Nyctalus leisleri, Nyctalus noctula and Nyctalus lasiopterus.
  • Characterization of cavities used by Noctules
  • Use of boxes for bats
  • Marking bats

The results can be translated in all cases in a series of practical manuals and guidelines aimed at managers and competent authorities on biodiversity and natural environment, with the aim of improving the conservation status of wildlife and integrated with forest management in differentforest habitats in Catalonia.
