Background The dataset presented in the current study contains information regarding alien vascularplant species found in the Middle Volga Region (South-East of the European part ofRussia). The dataset overall includes 413 species belonging to 247 genera and 67families. The described dataset is based on the data published during floristic studies from1851 to 2019. The dataset does not include alien vascular plant species that havepresently disappeared from the territory of the region. It contains a total of 7,782 records ofoccurrences, extracted from the Salix system of information and analytics, developed in theInstitute of Ecology of the Volga River Basin of the Russian Academy of Sciences.New informationA total of 7,782 records were published on the occurrence of alien vascular plants in theMiddle Volga Region. Each entry includes information regarding the place of occurrence ofthe alien plant species, the year of occurrence, the person who recorded the alien plantand who identified it, status of the species (introduced or invasive), link to the herbarium,which contains the specimen and the literary source. If it were impossible to establish thenames of the persons who collected the samples and (or) their identification in theidentifiedBy and recordedBy fields, the names of the authors of the publication given in theassociatedReferences field were entered. The presented dataset supplements theinformation on the distribution of alien plant species in the whole European part of Russiaand specifies the places of their findings in the Middle Volga Region © Senator S et al.

Background Data on the species diversity and distribution of pteridophytes (lycophytes and ferns) in the Urals and adjacent areas are presented. The dataset includes 13,742 observations of two classes Lycopodiopsida and Polypodiopsida. In total, the dataset contains information on 16 families, 28 generas, 65 species, four subspecies and nine interspecies hybrids. All records are for lycophytes and ferns collected over 170 years between 1853 and 2021. The dataset presented is based on herbarium specimens, published data and field research conducted by the authors. This dataset is the first and important step towards generalising information on the current diversity and geographical distribution of pteridophytes in the Urals and adjacent areas. © Melnikov D et al.
