Project Data

We present the results of the first nationwide survey of alien plant species in Romania, conducted between 2019 and 2022, in the framework of a national project coordinated by the Ministry of Environment, Waters and Forests and University of Bucharest. The present database complements and updates the database published by Sirbu et. al in 2022, which included occurrence records published until 2019. The new database includes 98323 occurrence records for 396 alien plant species in 77 families, with most species belonging to the Asteraceae family. One alien plant species in our database, the black locust Robinia pseudoacacia, had more than 10000 occurrence records. The distribution database also includes information on newly reported invasive alien plant species of Union concern in Romania (i.e., the floating primrose-willow Ludwigia peploides) and documents the presence of plants in 44 additional families compared to Sirbu et al. in 2022. Each database entry includes information on species taxonomy, location, year, person who recorded and identified the alien plant, geographical coordinates, and taxon rank.

Title Invasive species management in Romania according to REGULATION (EU) 1143/2014 on the prevention and management of the introduction and spread of invasive alien species

Funding The Operational Programme for Large Infrastructure (POIM 2014+ 120008) Invasive species management in Romania according to REGULATION (EU) 1143/2014 on the prevention and management of the introduction and spread of invasive alien species
Study Area Description Romania, Europe
Design Description Two survey methods were used: low-intensity survey and high-intensity survey. For the low-intensity survey, the survey of alien plant species was carried out in randomly selected grids of 100 km2 to cover Romania's surface in a balanced manner. Botanists randomly selected transects that were 50 km long and up to 50 m in width crossing over five consecutive 100 km2 quadrats, with a sampling station at each 10 km (i.e., five sampling stations on each transect). In the case of high-intensity surveys, the survey was carried out in 100 m2 quadrats located in randomly selected areas in every county. Occurrence data were collected with a GPS and survey forms were completed alongside photos for habitat and species identification. Specimens posing difficulty in on-site identification were collected for further examination and identification in the lab. Database curation was carried out by experienced botanists and biogeographers (authors of the paper)

Sampling Methods

Two survey methods were used: low-intensity survey and high-intensity survey. For the low-intensity survey, the survey of alien plant species was carried out in randomly selected grids of 100 sqkm. Within these grids, botanists randomly selected transects that were 50 km long and up to 50 m in width, with a sampling station at each 10 km (i.e., five sampling stations on each transect). In the case of high-intensity surveys, the survey was carried out in 100 sqm sampling plots located in randomly preselected areas. Occurrence data were collected in survey forms alongside photos for habitat and species identification. Specimens posing difficulty in on-site identification were collected for further examination and identification in the lab. Database curation was carried out by experienced botanists and biogeographers (authors of the paper).

Study Extent Romania

Method step description:

  1. Information regarding the occurrence records of alien plant species included in the database was collected between 2019-2022. The species taxonomy considered in the present paper is based on GBIF Backbone Taxonomy. The data were transferred to ArcGIS Pro and visually inspected for errors. The analysis were performed in ArcGIS Pro.
