Red Lists of the Hungarian dendroflora were compiled two: in 1989 and in 2003. They have also been provided with information about the threat levels of the Hungarian dendrotaxa and the endangering factors as well. The threat levels and categories were determined on the background of the recommendations by the IUCN. During the last fifteen years, 50 species of the dendroflora have become endangered; on the contrary, the levels of threat of 5 taxa have increased, and only one species could have been cancelled from the Red List. At present, there are 86 endangered tree and shrub species in Hungary. There are 21 stress factors endangering the Hungarian dendrotaxa, from which the proportion of habitat endangering factors is 76.8% and factors directly endangering the plants make 23.2%. This paper presents the whole list of the currently endangered species with the level of threat and the sources of danger, and a list of species possibly endangered in the near future. These lists provide an opportunity to follow the changing levels of threat in the future.
