The dataset includes records of earthworm species found on the territory of Krasnokutsk community. Krasnokutsk territorial commune (hromada) is located in the north-west of Kharkiv region. The natural complexes of the territory are represented by oak forests on the right banks and pine forests on the left banks of the rivers, floodplains, steppe beams, marshy alder trees. A significant part of the Krasnokutsk territorial commune consists of agricultural landscapes. The floodplains of the Merla and Merchyk rivers (the Dnipro river basin) were subjected to land reclamation in the 1970s, which radically changed the hydrological regime and affected on species of flora and fauna. In the pine forests there is the largest complex of forest peat bogs and lakes in the Kharkiv region.
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 8 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.

|Study Area Description||Krasnokutsk territorial commune (hromada) is located in the north-west of Kharkiv region. The natural complexes of the territory are represented by oak forests on the right banks and pine forests on the left banks of the rivers, floodplains, steppe beams, marshy alder trees. A significant part of the Krasnokutsk territorial commune consists of agricultural landscapes.

In the pine forests there is the largest complex of forest peat bogs and lakes in the Kharkiv region.|
|Design Description||The data presented in the dataset were collected during field research on the territory of Slobozhanskyi National Nature Park. The project steps were as follows: estimate the amount of data to be processed and their condition; contact other scientists with the offer of cooperation and publication of data of their authorship; digitize the data of field diaries; collect data from all local computers; divide the data into occurrence and sampling-event; format the data in a table according to the category; edit data sent by other researchers and add them to the general database.|
The personnel involved in the project:
Soil samples were taken with a size of 25x25 cm and a depth of 30 cm. The soil was viewed on a polyethylene film and the found earthworms were taken into a container with formalin. Samples were taken in three landforms (flat elevated area, slope and bottom of the ravine) on a transect at a distance of 5 meters from each other. Identification of earthworms was carried out in laboratory conditions. The database of field work results has been reformatted according to Darwin Core Archives standards. Exact sampling coordinates were not determined. We georeferenced them based on Google Satellite images (decimal latitude/decimal longitude as the centroid of the terrain point, followed by UncertaintyInMeters coordinates as the distance from the centroid to the farthest terrain point).
|Study Extent||Samples were taken in three landforms in the oak forest - flat elevated area, slope and bottom of the ravine|
Method step description:
- Field data collection: soil sampling on transects in flat elevated area, slope and bottom of the ravine; sorting earthworms and taking into a container with formalin
- Laboratory research: determination of morphological features and species identification of earthworms
- Database creation: reformatting thematic databases according to Darwin Core Archives standards
- Georeferencing based on Google Satellite images
- Data checking and cleaning in OpenRefine
