This page is outdated and refers to the period of February 2021 to
February 2022! Due to the Russian war against Ukraine and the suspension of the
Russian partner, we had to adjust our project plan.
The current status of the work plan can be found here .
This project aims at a consistent assessment of the potential future role of Norway spruce in the three model regions. To achieve our goal, we hypothesize:
- that current trends in growth and productivity, and in mortality and regeneration of Norway spruce in Western Ukraine and Southwest Germany are indicative of a non-sustainable development
- that gains in Norway spruce growth and productivity in the boreal forests of Northwest Russia can partially compensate for losses in the other regions.
We developed our research plan along three data streams: forest inventory data, forest growth data, and satellite data (see figure above). The three data streams are closely interlinked through the forest growth simulator EFISCEN.
Working packages (WP)
The project workload is split into several working packages. Besides an administrative base working package, there are seven working packages with different foci.
WP 1: Forest inventory data base
Development of the common template for all project partners for data collection and conducting of data collection which includes information about Norway spruce forest for the agreed regions in Western Ukraine (administrative units: Lviv, Ivano-Frankivs’k, Chernivtsi, Sakarpatska), Northwest Russia (administrative units: Leningrad region, Novgorod region, Pskov region) and Southwest Germany (administrative unit: Baden-Württemberg) in respect of area, growing stock, productivity, distribution of the area and growing stock over age classes (e.g., young, middle aged, premature, mature and over mature), increment (total and mean), allowable and real cuttings as well as damaging factors (incl. mortality). The official forest statistics will be used as the main source of information to guarantee the data quality and respective references. The collected data will serve as the data basis to implement and run the EFISCEN model for scenario modeling of Norway spruce forest development in the future.
WP 2: Growth data base
Selection of sample sites according to different age groups of Norway spruce (age classes: less than 40 years; 41-80 years and more than 80). Additionally, the sample sites will be stratified according to (i) altitude, (ii) slope aspects, (iii) forest site types, (iv) types of geographical positions, for all model regions in Western Ukraine, Northwest Russia and Southwest Germany. Increment cores will be taken from sample trees. Tree-ring width will be measured on increment cores using the existing measurement stations at partner institutions. Growth data will be quality checked and cross-dated according to the principles applied in dendroecological and growth and yield studies. The growth data will be preprocessed to same conditions for the compilation of the common growth database.
WP 3: Satellite data base
Collection of satellite images from different sensors (MODIS, Landsat and Sentinel-2) according to areas of interests of different regions of investigation (Western Ukraine, Northwest Russia and Southwest Germany). All available satellite data from the beginning of surveying (for example for Landsat from the 1980s, MODIS from 2000 and Sentinel-2 from 2015) without cloud cover (less than 10%) within 5-years periods will be collected. For these images pre-processing algorithms (atmospheric corrections, stacking images, etc.) and database will be developed. For the images NDVI-indexes will be calculated for detecting relations with growth data. For all three model regions the dynamics of coniferous wood cover will be estimated in 5-year periods.
WP 4: GIS data base
Development of the structure of specialized multilayer GIS database with the aim to combine and analyze the remote sensing (satellite images) and ground true (tree rings) georeferenced data on Norway spruce for the agreed areas in Western Ukraine, Northwest Russia and Southwest Germany. Retrospective analysis of Norway spruce tree growth on North-South gradient for Northwest Russia and elevation above sea level incl. temperature gradient for Western Ukraine and Southwest Germany.
WP 5: Growth simulation
So far EFISCEN has not been used for the assessment of forest development and timber supply based on National Forest Inventory (NFI) data in Baden-Württemberg. The model will be run using the most recent NFI data from 2012. This data as well as those from Western Ukraine and Northwest Russia has to be prepared and specified according to the requirements of EFISCEN. A major task will be to fit the growth functions for Norway spruce. Different scenarios will be developed. The results obtained for the Baden-Württemberg region will be compared with the projections made by the German WEHAM-model for validation. The results of the EFISCEN results for the three regions will be analyzed and interpreted jointly.

WP 6: Synthesis
Based on the results from the forest growth simulation, the implications of the different scenarios on ecosystem services provided by the forests, like provisioning and regulating services, but also social and supporting services will be discussed. We will use published functional relationships between ecosystem structures (as provided by the scenario modelling) and ecosystem functions to derive a synthesis assessment.
WP 7: Outreach
The planned outreach activities aim at transferring the newly generated information and scientific knowledge into forest-based land-use planning in order to guide decision makers on strategic, tactical and operational levels. This will be achieved through the active participation of actors in the dissemination of project results, including
- preparation of scientific material/publications based on the data and ideas developed and obtained during the projects’ lifetime
- development of teaching materials for the students on bachelor, master and PhD levels, such as thematic modules in the courses on sustainable forest management
- using of project outcomes in refreshing teaching
- reporting of the project results at scientific conferences, seminars, workshops, summer schools etc. as well as present-ing them in mass media and for interested target groups such as forest authorities, forest managers, representatives of forest business, NGOs in nature protection etc., and
- through the development of this project website and issue of thematic leaflets.
