The main goal of the research in the Tallinn Botanic Garden is to study the diversity of the plant kingdom, the distribution of plant species, as well as biology and ecology.
Field of Research:
Reproductive biology and restoration ecology of endangered plant species
The scope of the research covers species biology, ecology, reproductive biology and restoration ecology of endangered plant species in Estonia and beyond, both in and outside their natural habitats. The study aims to develop methods for propagation of endangered species, improvement of the conditions of their natural populations and artificial establishment of populations in areas where appropriate habitat conditions are available. Within the scope of conservation oriented research, establishment of plant population and community based ex-situ conservation collections of endangered species of Estonia at Tallinn Botanic Garden has been started.
The research is focused on different aspects of urban biodiversity. The aim is to conduct biodiversity studies and provide new approaches to maintain and increase biodiversity within Estonian capital Tallinn. Research on possibilities of artificial establishments of populations of protected species and communities within urban landscape enables to develop and test appropriate methodologies and thereby gather specific knowledge. Planned activities meet the objectives foreseen in the strategy “Tallinn 2030”: “protecting biodiversity, increasing the species diversity and environmental stability of the urban landscape and increasing the resistance of ecosystems to the impacts of human activity.”
Biomonitoring of air pollution
The topic “Use of mosses as biomonitors of atmospheric deposition of trace elements” is one of the sub-programmes of the Estonian national environmental monitoring programme as well a part of the cooperation programme of 32 European countries on surveying the concentration of heavy metals in European mosses. The European programme for cooperation in biomonitoring is a part of the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops under the UN Convention on Long-Range Transboundary Air Pollution. The use of bioindicators is a suitable method for the detection of long-term load of airborne pollution with heavy metals. The Estonian moss survey provides data on concentrations of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), lead (Pb), zinc (Zn) and vanadium (V) in naturally growing mosses since 1994, since 2005 also for the nitrogen (N) and since 2010 also for the aluminium (Al), arsenic (As), mercury (Hg) and titanium (Ti).
