−
EFIMOD uses soil and stand-level inputs from forest inventory database. Each record such databases contains the description of one forest compartment. There is the data characterizing the forest compartment as a whole as well as the data on individual forest elements. Forest inventory data are: stand composition, dominant tree species in overstorey, relative stand density, stand growing stock, yield class (designating site productivity), and forest site class (denoting environmental conditions). Characteristics of separate forest element are: age, average height and average stem diameter at breast height (DBH), number of trees per hectare. Also the characteristics of soil organic matter pool are needed: the stocks of soil organic matter and nitrogen in different soil layers.
+
The system uses stand-level inputs from forest inventory database, the pools of soil organic matter and nitrogen in different soil layers, and climatic and hydrological data. Detailed list of input parameters you may find at [http://ecomodelling.ru/index.php/en/models/ EFIMOD-DLES webpage].

Ecological Modelling 138 (1-3): 289-308.</ref> of soil organic matter (SOM) and nitrogen mineralisation and humification is based on a classic concept of ‘humus type’ (Humusform) as a succession stage of SOM decomposition marked by different groups of soil micro-organisms and fauna inherent to forest soils. It has the following processes: (i) full mineralisation of every compartment, (ii) processes of organic debris transformation to humified matter by three different complexes of reducer organisms that are responsible for the formation of the three main humus forms. It calculates the transformation (humification and mineralisation) of litter and SOM compartments, the gross carbon dioxide flow from the soil due to SOM mineralisation and the nitrogen available for plant growth. The rate of litter and SOM mineralisation and humification is dependent on the litter quality, soil temperature and moisture, and on some soil parameters.

The main specific feature of this model is that it calculates the processes of SOM transformation separately for organic layer (forest floor, peat) and mineral topsoil. The other important peculiarity of the model is the use of the results of laboratory experiments on the decomposition of different organic debris in controlled conditions as the experimental data for the model compilation obtained from published and authors’ own data<ref> Chertov O.G. 1985.  Simulation model of forest litter and floor mineralization and humification.  J.

A comparison of the performance of nine soil organic matter models using datasets from seven long-term experiments. Geoderma 81 (1/2): 153-225.</ref>. To run the ROMUL model the following input data are necessary: the amount of litter input with an unlimited number of cohorts (which are characterised by their specific nitrogen and ash content), initial SOM pools, and climate data, air temperature, soil temperature at the 20 cm depth, forest floor moisture and soil moisture. The output parameters of the model include data on all residual litter cohorts, all SOM and nitrogen pools, and some flow parameters: gross carbon dioxide and available mineral nitrogen production from all litter and SOM pools. A special climate generator [[#Climate models|SCLISS]] was compiled to produce time series of soil temperature and moisture from standard monthly meteorological data on air temperature and precipitation.

The model uses monthly average data on air, litter and soil temperature, precipitation, litter and mineral soil moisture. Air temperature and precipitation are usually measured at numerous meteorological stations, soil and litter data are seldom measured and, moreover, these data are mostly a result of scientific forest studies. Therefore, the procedure of simulating the necessary monthly meteorological input data is an important sub-model of the whole ecosystem model and should be linked with the soil organic matter model. One tried to develop a simple statistical model for the simulations of these data.

ADDITIONAL INFORMATION (needs to be migrated using the "edit with form" link)

Scope of the system

The tool provides information to assess forest/soil natural development, forest/land-use management, and different scenarios of external impacts.

System origin

It was developed by a researchers’ team in the Institute of Physico-Chemical and Biological Problems in Soil Science (Pushchino, Russia) and Biological Institute of Sankt-Petersburg State University with support of European Forest Institute (Joensuu, Finland) and Joensuu University (Joensuu, Finland). First prototype was implemented in 1996 being not a commercial product and based on earlier models by O.Chertov. The tool has been applied in Russia, Finland, Sweden, Canada, the Netherlands, Bulgaria, Czech Republic, and in several international projects (three projects in INTAS EU Program, FP5 EU-Programme Project CT98-4124 “Relationships Between Recent Changes of Growth and Nutrition of Norway Spruce, Scots Pine, and European Beech Forests in Europe (RECOGNITION)”, FP6 EU Programme INCO - 013388 “Impacts and risks from anthrpogenic disturbances on soils, carbon dynamics and vegetation in podzolic ecosystems (OMRISK)” and other projects. It has been implemented also for several applications in frame of the National Program of Russian Academy of Sciences “Change of Environment and Climate”.

Application of EFIMOD

Support for specific issues

The system is designed to take into account timber harvest effects, dynamics of ecosystem and forest understorey biodiversivity, climate change effects, landscape analysis methods, nitrogen deposition effects, and fires.

Support for specific thematic areas of a problem type

  • Silvicultural
  • Conservation
  • Restoration
  • Development choices / land use zoning
  • Sustainability impact assessment (SIA)

Capability to support decision making phases

In current version, the GUI helps the user to compare dynamics of ecosystem parameters (e.g. growing stock, stand and soil carbon and nitrogen pools, biodiversity ranks etc.) at different scenarios of forest management and other external impacts.

CommonGIS

Data and data models

Typical spatial extent of application

The application can be used on regional, forest-enterprise, and forest stand scale.

Forest data input

The system uses stand-level inputs from forest inventory database, the pools of soil organic matter and nitrogen in different soil layers, and climatic and hydrological data. Detailed list of input parameters you may find at EFIMOD-DLES webpage.

Type of information input from user (via GUI)

User may define the scenario of forest ecosystem development via specifying various management options, such as different types of cuttings, plantings etc.; external impacts, such as fires, climate change, different levels of nitrogen deposition. For biodiversity assessment, regional phytosociological data is required.

Models

Forest model

Flowchart of EFIMOD model

The modelling tool of forest ecosystem EFIMOD [1][2][3] is an individual-based spatially explicit simulator of tree-soil system that calculates parameters of carbon balance and standard forest inventory characteristics: NPP, Rh, soil available nitrogen, tree and stand biomass by tree compartments, soil organic matter (SOM) and N pools, stand density, height, DBH, growing stock and some other parameters. It includes soil model ROMUL as an important component[4] that is driven by soil water, temperature and SOM parameters. The statistical generator of soil climate SCLISS was compiled to run ROMUL. The EFIMOD allows for a calculation the effect of silvicultural operations and forest fires. Now it is linked with a system of plant biodiversity assessment BioCalc.

Soil model

Flowchart of ROMUL model

The ROMUL model[5][6] of soil organic matter (SOM) and nitrogen mineralisation and humification calculates the transformation of litter and SOM compartments, the gross carbon dioxide flow from the soil due to SOM mineralisation and the nitrogen available for plant growth. The rate of litter and SOM mineralisation and humification is dependent on the litter quality, soil temperature and moisture, and on some soil parameters. The model validation and sensitivity analyses had been performed using a set of published laboratory and field experiments[7][8][9].

Climate model

A soil climate generator SCLISS[10] is used in the model for two purposes: (1) as a method of evaluation of soil temperature and moisture using measured standard meteorological long-term data; (2) statistical simulation (generation) of realisations of long-term series of necessary input climate data with known statistical properties. The model uses monthly average data on air, litter and soil temperature, precipitation, litter and mineral soil moisture.

Model of biodiversity

A model BioCalc (BIOdiversity CALCulator) forecasts dynamics of ecosystem and species understorey diversity of each forest unit along the EFIMOD simulation outputs on a base of standard forest inventory data linked with the results of detailed phytosociological research [11].

More detailed description of models you may find at EFIMOD-DLES webpage.
