Earthworm communities (Oligochaeta: Lumbricidae) in old-growth and young forests of protected areas of the Kaluga Oblast (European Russia)

Description

This dataset represents data of earthworms surveys collected in 2 protected areas (Kaluzhskiye Zaseki Nature Reserve and Ugra National Park) in Kaluga Oblast, Russia. Earthworms were sampled by digging-out and hand-sorting (by layers) of the soil samples of 25 * 25 cm and a depth of c. 35 cm in different locations (sampling plots). Some locations were investigated once, some several times within one year or several years. Due to such sampling design the dataset includes 3 types of events: (1) the survey (soil samples collected in the location during one sampling period), (2) soil sample (part of the survey, one sample of 25 * 25 cm and a depth of c. 35 cm collected during the survey), including empty samples, and (3) soil sample layer (part of the soil sample). Occurrence data provide 6673 earthworms occurrences in soil sample layers with life stage (juvenile, adult, or subadult), and biomass for each individual, as well as 271 earthworms occurrences in the survey with density for each survey.

Geographic Coverages

Kaluga Oblast is situated in the central part of the East European Plain. The climate is moderately continental with distinct seasons: warm and humid summers and cold winters with stable snow-cover (4-5 months). The mean annual precipitation of 600 mm and the mean annual temperature is about +4°C . The total area covered by forests is around 1,380,000 ha (46% of the oblast territory). Agricultural lands occupied an area of 1,350,000 ha (44% of the territory). Earthworms were sampled from two nature protected areas: "Kaluzhskiye Zaseki" Nature Reserve. The Reserve was established in 1992 due to the presence of unique old-growth broad-leaved forests that were mostly undisturbed by cutting and ploughing. The total area of the Reserve is 185 km2. The Reserve consists of two separate parts, 12 km apart. Sampling plots were located in both clusters. The oldest patches of broad-leaved forests are remains of defence line against the raid of nomads and was under state protection for centuries. Ugra National Park was established in 1997 to protect typical landscapes of Central Russia and became a UNESCO biosphere reserve in 2002. The National Park consists of seven clusters grouped into three areas with a total area of 986,245 sq km. This study was conducted in the Zhizdra cluster.
