The aims of the paper are to present a list of vascular plants of the Wzgórza Łomnickie Hills (the Sudety Mts., SW Poland) and to explain the nature and consequences of main antropogenic and biogeographic influences on local flora. The detailed field exploration yielded a list of 585 species. Supplemented by both published sources and observations after 1980, the total number of vascular plant species reached the number of 615. To understand the essence of anthropogenic transformations of the local flora I examined biological spectrum of life forms, distribution type and groups of synanthropic plant contributions. The analysis shows qualitative and quantitative changes of flora composition. Non-indigenous species constitute 18.70% of total. The proportion among life form groups has changed and is being influenced by different types of human activity. The comparision of the local floras within similar regions in the Sudety Mts. revealed transformations in the contribution of different taxonomic units. It is the effect of the presence of numerous alien plants (e.g. non-indigenous species respectively constitute 40.7% and 20% of Brassicaceae and Scrophulariaceae) as well as a particular type of land usage (ponds development has considerably increased the percentage of Cyperaceae).
