Pētījumu programmas otrajā etapā turpināts darbs pie mežsaimniecības ietekmes uz meža un saistīto ekosistēmu pakalpojumiem izpētes dažādos telpiskos un laika mērogos četrās aktivitātēs.
Activity 1. Assessment of landscape-level impact of forest management on the quality of regulating and provisioning forest ecosystem services. Sampling according to the sampling schedule has been continued in the model areas of Zalvite and Slitere – soil solution, groundwater, runoff. Repeated vegetation survey along 8 reconstructed ditches and forest roads was conducted. Mapping of forest ecosystem services in the model areas has been carried out, by developing new indicators and improving already developed ones. Sampling in the biomass removal objects has been continued for the 6th season – soil solution, groundwater, runoff, litter. Second survey of the young stand has been carried out in these objects.
Activity 2. Assessment of sustainably intensified forest management short- and long-term impact on the quality of provisioning, regulating and supporting forest ecosystem services. Repeated assessment of the development of Phlebiopsis gigantea on large logging residues has been carried out. Sampling of soil solution and precipitation has been continued in the objects of assessment of stump removal mid-term effects. Measurement of the young stand, survey of beetles and evaluation of root rot occurence has been carried out in these plots. Establishment and measurement of sample plots for the evaluation of stump removal long term effects and large scale logging was being continued.
Activity 3. Interaction between forest management and provisioning forest ecosystem services – accessibility and quality of non-wood forest products (NWFPs). Three surveys have been organized about the importance and use of non-wood forest products: inhabitants, hunter clubs and individual hunters. Assessment of the importance of forest for beekeeping has been performed. Analysis of non-wood forest products has been conducted on National forest inventory plots and on a regular basis (forest berries and mushrooms) – in special routes established in Northern Kurzeme and Vidusdaugava regions, as well as forest thinning plots.
Activity 4. Interaction between forest management and aesthetic and recreational forest ecosystem services. Survey of inhabitants about their recreational preferences in different seasons has been carried out, results about spring, summer and autumn preferences are included in the report. Assessment of visual quality of forest landscape with different degree of forest management impact has been carried out, both by landscape architect (professional opinion) and inhabitants (visual preferences).
