Spiders of the National Nature Park Dvorichanskyi (Northeastern Ukraine)

The database includes records of 211 spider species in 25 families collected in the "Dvorichanskyi" National Nature Park and its vicinity. The park was created for the conservation of chalk grasslands and the landscape complexity of northeastern Ukraine. It hosts chalky hills at various stages of grassland succession, gullies with shrubs and steppe-like meadows, floodplain meadows, and an oak forest on the right high riverbank; a floodplain forest and a narrow strip of wetlands neighbor the park. The sandy river terrace is planted with pine trees. Chalky hills stretch along the Oskil river making a mosaic of specific calcareous vegetation. Natural habitats are surrounded by agricultural lands. Additional records representing new species of spiders registered in the study area was added on 17 January 2023.本数据库收录了在"德沃里昌斯基国家自然公园（Dvorichanskyi National Nature Park）"及其周边区域采集的25科211种蜘蛛的记录。该公园设立初衷为保护乌克兰东北部的白垩草原及其景观复杂性。园区内涵盖处于不同草原演替阶段的白垩质丘陵、生长灌丛与类草原草甸的沟壑、泛滥平原草甸，以及右侧高河岸地带的橡树林；公园毗邻一片泛滥平原森林与狭长湿地带。沙质河阶地种植有松林。白垩质丘陵沿奥斯基尔河（Oskil River）延伸，形成了独具特色的石灰质植被镶嵌群落。原生栖息地被农田环绕。本数据集于2023年1月17日补充了在该研究区域内新记录到的蜘蛛新种相关数据。
