How progress the implementation of demonstration pilot actions

... in Catalunya

Within the framework of the activity 2.4 of the SUDOE-CERES project, forestry actions have been carried out during this summer-autumn of 2020 in two demonstration pilot sites at stand scale (hillside of a massif) in an area of about 90 ha in the Ports Natural Park and 300 ha in the Capçaleres del Ter Natural Park.

The common objective of both was to improve the connectivity and ecological integrity of the key elements of maturity and naturalness by integrating different types of silvicultural treatments for a target group of species. For the optimization of the actions, Marxan with Zones was used, a software that implements a methodology to support decision-making on how and where it is more efficient to implement sylvicultural actions with multiple benefits for biodiversity, the continuity of habitats and connectivity. for a set of umbrella, threatened and / or protected species. The silvicultural treatment carried out consisted of generating dead wood of different sizes on the ground and standing, increasing maturity, tree heterogeneity and generating small gaps.

In Capçaleres Natural Park, the treatment has improved the habitat and connectivity for the breeding, food and shelter of capercaillie (Tetrao urogallus), the black woodpecker (Dryocopus martius), the boreal owl (Aegolius funereus), the Eurasian treecreeper (Certhia familiaris), species of arboreal bats such as barbastela (Barbastella barbastellus) and for a set of saproxylic beetles.

In Ports Natural Park, the treatment has improved the habitat and connectivity for a set of saproxylic beetles with different dispersal capacities and wood requirements such as Ergates faber and Tragosoma depsarium, improve the growth conditions of accompanying tree species, generating gaps to improve the pasture for roe deer (Capreolus capreolus) and protected flora species such as Centaurea podospermifolia, Pyrola chloranta and Orthilia secunda and, finally,improve the habitat conditions for barbastela (Barbastella barbastellus).
