Invasive plant species and their threat to biodiversity

The problem of the uncontrolled spread alien plant species matured in world second half 20th century, and recent decades it has become main threat to biological diversity various regions world. Prevention Invasions is a new urgent task field nature protection, which determines relevance study. purpose study determine predict distribution area invasive plants, based on use following methods: comparative morphological-ecological-geographical, route using determinants atlases plants Ukraine, method structural analysis. It established that characteristic features are very high tolerance habitat climatic conditions, rate reproduction, simple effective by wind, water, animals, rapid growth, contributes displacement slow-growing other absence natural enemies restrictions. A particular danger biodiversity Ukraine species: Sosnowsky’s Hogweed (Heracleum sosnowskyi), Canadian Goldenrod (Solidago canadensis L), American maple (Acer negundo L.), Red Oak (Quercus rubra), Common Ragweed (Ambrosia artemisiifolia Milkweed (Asclepias syriaca Silver Berry (Elaeagnus angustifolia), pokeweed (Phytolacca Americana), Ecballium (Ecballium elaterium), Sandbur (Cenchrus pauciflorus Benth), Wall Barley (Hordeum murinum Jerusalem Artichoke (Helianthus tuberosus), etc. results an important scientific practical basis for developing national regional strategies controlling
