Adrián Pascual was born and raised in Valladolid, Spain. He received his Bachelor degree in Forestry Engineering (2010) and his master’s degree (2012) both from the University of Valladolid. After two years working in Spain, he took off to Joensuu, Finland, where he is pursuing his PhD at the University of Eastern Finland (UEF). During the last three years, Adrián's work at the UEF includes the formulation of spatial optimization problems making use of remote sensing data to compose dynamic treatment units. The EFI SSV grant will take him to Lleida, Spain. Follow Adrían on Twitter: @AdPscual

Adrián Pascual (University of Eastern Finland) will be hosted by Sergio de Miguel (Deparment of Crop and Forest Science, University of Lleida).

The aim of the project is to optimise forest planning combining the production of timber and mushrooms including species-specific mushroom yield models based on forest attributes and climate-related information. For this purpose, we will make use of a time-series data from 1997 to 2017 in which mushroom yield is measured periodically from permanent plots established in different forest ecosystems located in Catalonia (north-eastern Spain). These new observations increase the geographical scope of previous research by including new forest ecosystems such as Aleppo pine ( Pinus halepensis) and mountain pine ( Pinus uncinata) forests in which the ecological dynamics and economic importance of mushroom yield and timber production might be substantially different as compared to other study areas in Scots pine ( Pinus sylvestris) and black pine ( Pinus nigra) forests which are likely to be more profitable in forestry.

To test this, we will make use of the aforesaid mushroom yield measurements and models together with existing stand-dynamics models developed based on National Forest Inventory (NFI) plots for the pine forest species located in Catalonia. Based on these two sources, we will develop optimal management instructions considering the joint production of timber and mushrooms and comparing the results to a scenario where timber production is maximised. Moreover, the provision of mushroom-based ecosystem services (i.e., total biomass, wild food and traded non-wood forest products) are strongly dependent on meteorological and climatic conditions. As a result, it might be possible to derive forest management instructions by integrating the meteorological uncertainty driving future mushroom productivity.

New scientific evidence has proved that harvesting activities can boost mushroom production under certain conditions and in certain ecosystems rather than reported in early studies (Bonet et al., 2012). In this regard, another contribution of the visit will be to evaluate the impact of thinning intensity and effects on optimal forest management as compared to previous research (Palahí et al., 2009).
