Station Description:

General Description:

Site is situated at territory of the Central Forest Biosphere State Reserve (founded in 1931).

The experimental site is located in the Central Forest Reserve (CFR) at Fedorovskoye, near the town of Nelidovo (Tver region), about 300 km WNW of Moscow in European Russia.

The eddy tower is mounted in a 150 year old forests spruce forest of Sphagnum-Vaccinium myrtillus type. This is a widespread forest type in northern, central and southern taiga, but is mostly limited to the middle and lower parts of soft slopes and shallow depressions with peaty podzolic gley soils, very weak surface runoff, and high ground water level. These stands are typically characterised by simple vertical structure and long-lasting periods of flooding by temporary perched water, low oxygen content (0.1-3.2 mg l-1) of ground water, poor soil aeration, low soil nitrogen content (0.5-9.9 kg ha-1), and acidic reaction to the depth of >100cm (pH H2O ranges to 3.53-3.83 in the 0-40 cm soil layer) (Karpov, 1973; 1983). The main stock of soil carbon is concentrated in peat horizon and has been estimated for the measurement site at 197 tC ha-1 (Schulze et al., 2002). The soil root layer is 0-20cm. The low shrub-grass layer is dominated by Vaccinium myrtillus and V.vitis-idaea and the moss layer is typical with Sphagnum girgensohnii and S. magellanicum. Within the ground layer Pleurozium schreberi, Hylocomium splensens and Polytrichum commune occur as well (Abrajko, 1973). The stand is approximately 27 m high, consisting of about 86% Picea abies trees and about 14% Betula spp. with a total live tree density of 565 ha-1 in 2000 (Vygodskaya et al., 2002) Above ground woody biomass is approximately 63 tC ha-1 (Schulze et al., 2002) with a projected leaf area index of about 3.5 (Schulze et al., 1999).

The measurement tower is situated in a shallow depression. The territory around the tower is rather heterogeneous. The dominant spruce stand is limited in extent and within 200-300 m from the tower there are birch and aspen forests as well as windfall of different ages. A comprehensive footprint analysis of the area around the tower, taking into account the heterogeneous nature of the vegetation beyond the spruce stand has been made by Sogachev et al. (2002). They suggested that typically around 80% of the measured flux originates from within a 200 m radius during the day, with the effective footprint being somewhat larger at night.

The forest tower is situated is a depression which consists of peat 1 m thick light dust-loam located under 50-80 cm of peat.
