Moss occurrences of the Great Vasyugan Bog system

Study Extent

The dataset includes the author's materials from 4 key sites in the adjacent territories of the Novosibirsk and Tomsk regions: 1) vicinity Targach lake - [N 5615-5617 - 08132-08134 E, altitude about 150 m above sea level] - the site is located in the axial part of the mire system near its southwestern tip. 2) north of the village of Nadezhdinka - [N 5652-5655 – 07823-07828 E, 130 m above sea level] - in the axial part of the mire system, in its central part - in the sources of the rivers Malaya and Bolshaya Icha and the Chuzik river (Parabel district) 3) north of Uzas Settlement - [N 5707-5712 – 07653-07656 E, 128 m above sea level] - in the axial part of the mire system,in its northwestern third - in the in the basins of the rivers Cheka, Chertala and Bol.Petryaka. 4) east of the village of Kop-Cordon – [N 5622- 5624 07930-07954 E, 135-150 m above sea level] Severnoye Distr., Novosibirsk region, on the territory of the Vasyugansky Nature Reserv. And some points on southern periphery, in Severnoye and Kyshtovka districts of Novosibirsk region were also investigated. The surveyed sites are located near the border of the bioclimatic zones of the southern taiga and the subtaiga.

Sampling

In most cases bryological investigations were in parallel with the geobotanical relevés of the plots; moss samples were collected on each type of substrate. Rock outcrops and habitats along crooks were the objects of special attention. Standard methods of moss collection have been used. Preserved samples are in NSK.

Quality Control

The data were collected and identified by reseachers from the Central Siberian Botanical Gagden of the Siberian Branch of the Russian Academy of Sciences.

Method steps

1. The source materials are stored in two personal databases. Geobotanical and bryological materials are stored in the IBIS (Zverev, 2007). Herbarium label data can be found in the Excell table (partially available on the website). The materials were brought together in the Excell table and revised; the names and contents of the fields were aligned with Darwin Core (Wieczorek et al. 2012) and include the following: “occurrenceID”, “taxonID”, “scientificName”, “taxonRank”, “kingdom”, “family”, “genus”, “acceptedNameUsage”, “country”, “countryCode”, “stateProvince”, “county”, “verbatimLocality”, “habitat”, “locationRemarks”, “fieldNotes” (extended field description of habitat, in Russian), “verbatimElevation”, “decimalLatitude”, “decimalLongitude”, “coordinateUncertaintyInMeters”, “day”, “month”, “year”, “identifiedBy”, “recordedBy”, “basisOfRecord”, “collectionCode”, “catalogNumber” (number of a specimen in herbarium NSK), “datasetName”.

The Great Vasyugan Bog is a huge branched peat-mire system occupying the central part of the Ob-Irtysh interfluve. The BVB is considered the largest mire system in the world, its area reaches 50 thousand square kilometers with a length more than 450 km from the sources of the river Yagylyakh to the sources of the Shegarka River.
