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

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.
