title: Raw data from: Relative impact of native and non-native plants on endangered species in a major European city

description: The data set forms the basis for the evaluation of the causes of
 endangerment of plants of particular conservation concern in Berlin,
 Germany. The data set is the basis for the manuscript 'Relative
 impact of native and non-native plants on endangered species in a major
 European city', published in Journal of Applied Ecology. The causes
 of threat were recorded and assessed by experts during field surveys.
 Because populations can be subject to various threats, several threats can
 be assigned to a single population. The population is clearly identified
 by the population ID. Because the original data set was collected as part
 of the Berlin Flora Protection Programme, the data fields ‘Threat’ and
 ‘Threat_annotation’ are in German.

 Description of the data and file structure The data set forms the basis
 for the evaluation of the causes of endangerment of plants of particular
 conservation concern in Berlin, Germany. The original data set was
 collected as part of the Berlin Flora Protection by the 'Stiftung
 Naturschutz Berlin'. ### Files and variables #### File:
 Raw_data_Relative_impact_of_native_and_non-native_plants_on_endangered_species.xlsx **Description:**  The causes of threat for all mapped populations of target species of the Berlin Flora protection scheme were recorded and assessed by experts during field surveys for an individual population. Because populations can be subject to various threats, several threats can be assigned to a single population. The population is clearly identified by the population ID. The datafield 'Threat' lists a threat category that was assigned to a threatened plant population by experts during field surveys. ##### Variables * Population_ID\ indicates a unique population of a threatened plant species * Species_ID\ a unique ID for plant species according to the German database on plant species 'FloraWeb' - https://www.floraweb.de/ * Genus\ indicates the genus of the threatened plant species * Species\ indicates the species suffix of the threatened plant species * Sensu\ taxonomic information on minor taxa and species groups * Author\ indicates the first author of a scientific plant name * Threat_ID\ an ID for each threat category * Threat:\ a threat category that was assigned to a threatened plant population by experts during field surveys * Biotop_ID\ an ID for a biotope category of the Berlin classification scheme for biotopes * Biotope\ the main biotope category of the Berlin classification scheme of the respective Biotope_ID * Missing values\ Missing values are indicated by blank cells ## Code/software Microsoft Excel or other spreadsheet-software that can read .xlsx files ## Access information Other publicly accessible locations of the data: * no publicly accessible locations Data was derived from the following sources: * no publicly accessible sources
