Biodiversity is one of the most important aspects of the environment. It maintains the balance of the environment. But nowadays is this balance very often disrupted with many negative influences of human activities. In the first steps of revitalization or remediation of disrupted environment, plants with specific characteristics (tolerance and hyperaccumulation ability), play important roles. Therefore the knowledge of molecular, biochemical and physiological aspects of these plant abilities is inevitable. Through this plant potential it is possible to revive the environment with its biodiversity. Sustainable environment with the biodiversity of organisms can be considered as one of the most important aspects of the healthy life. Biodiversity is also one of the main activities of the Center of Excellence for Protection and Use of Landscape and Biodiversity of the Operational Programme Research and Development financed by the European Regional Development Fund. The list of suitable plants for phytoremediation with their characteristics, behaviour in contaminated milieu, and possible cultivation will be integrated to the databasis of workplaces of other partners resulting in complex information system aimed on studies of the biodiversity in the Center of Excellence.
