XVI International Botanical Congess

The effects of oil products and fires on growth dynamics of two types of primary vegetation Tamarisetum and Phragmitetum in accident area are examined using methods of mapping and monitoring. On soil heavy flooded by oil products Salicornia europea appears in low tier on second year, Tamarix bushes grow normally. On soil slightly flooded by oil products and heavy fired of Phragmites australis plants and initial grassy cover recover up to 100%. On first lot in two years Solcornia europea grows thin and Aeluropus littoralis appears evevywhere together with some others annual halophyls. The portion of perential cereal creepes increases (phytomasse 20-30 %), initial grassy cover recovers gradually. In second case Phragmitetum recovers at once, but more sparsely.
