Project summary

The aim of the Project is elaboartion of methods for restoration of the plant cover under intensive recreation using a new system of compounds-regulators of plant growth and development and a complex assessment of the state of the environment.

The qualitative assessment of status of natural ecosystems under anthropogenic influence is specified by the need of correct determination of their state for economic substantiation of real and potential losses and realization of monitoring the restoration dynamics of disturbed plant communities. Presently, elaboration of effective methods for reclamation of damaged biosystems is a topical problem, especially for the regions where the reestablishment of the plant cover is related to great difficulties because of specific natural conditions. In this connection, search for and elaboration of effective, low-cost and ecologically safe technologies for restoration of disturbed territories are the major conditions of solving this problem.

Within the Project, the previous experience in phytocenology along with the currrent advances of ecotoxicology will be used for the further improvement of generalized assessment of the state of plant comminities developing under anthropogenic impact.

The determination of the damage caused to plant communities is suggested to be performed by the elaborated formalized index – Integral index of safety of phytocenoses (IIPhS) that is an ecologically significant index characterizing changes in the environment over a definite area.

One of the important current problems is elaboration of effective, low-cost and safe methods for reclamation of damaged ecosystems. The suggested new system of compounds-regulators of plant growth and development "Pra-Nature LIVE!" meets these requirements.

"Pra-Nature LIVE!" is a principally new system of compounds stimulating the growth and development of plants. The composition of the new system "Pra-Nature LIVE!" is based on available, permissible, and widely applied in USA, EC, Japan, and Russia components (food products and microelement fertilizers). Compounds of the "Pra-Nature LIVE!" systems are solid “carriers” covered with microelements, whose proportion is carefully selected. The essence of the "Pra-Nature LIVE!" compounds is their catalytic action for a cascade of biochemical and physiological processes related to the growth and development of plants independently of their taxonomic position. At the same time, these components are not sources of plant nutrition, but they promote plant nutrition due to the active consumption of the necessary nutrients from the environment.

The use of the principally new approach to the reestablishment of the plant and soil covers promotes realization of the natural potential of plants without touching upon gene material. So, the maintenance of the natural mechanism of optimizing the viability of plants leads to the fact that plant systems become more resistant to changes in the environment: drastic changes in temperature and moisture regimes, effects of pests and etc.

Within the testing of the proposed system of compounds, the unique results on the restoration of natural plant communities have been obtained. It was impossible to get them using traditional methods. For instance, the major characteristics of gramineous and coniferous species growth in the laboratory experiments were the following: seed germination increased by 150 and 180%, respectively; biomass increased by 180 and 200%, respectively (photo illustrated the preliminary tests are given in Section Additional Information).

There is a good reason to believe that the use of the new system of compounds-regulators of plant growth and development under application of low-cost technologies will provide an accelerated restoration of tRASsformed natural communities up to their initial state. As a result, the use of the new group of compounds in disturbed sites is the most prospective trend in solution of the problem of reestablishing components of plant comminities (in the necessary proportion) and entire plant community.

The functioning of plant communities in relation with other environmental components determines a need for studying ecologo-cenotic relationships. Therefore, we plan to investigate soil algosinusia and micro- and mesofauna of soils, which are reliable indicators of the state of the environmental conditions.

Two kinds of experiments – laboratory and microfield – are planned to verify the elaborated system of plant growth and development. A purpose of such complex works under laboratory and field conditions is to reveal relationships between the applied doses of compounds-regulators and their chemical and biological effects on the environment - soil and ground plant covers under natural conditions of functioning a complex system of biogeocenosis.

The following tasks are suggested to be solved:

· To investigate complex biological activity of compounds-regulators and their new working forms;

· To elaborate methods of complex assessment of state of ecosystems damaged to various degree under recreation;

· To estimate effects of compounds-regulators on monocultures of wild plant species in laboratory;

· To estimate effects of compounds-regulators on the plant growth and restoration of plant communities;

· To elaborate a complex of measures for using methods of assessment and restoration of vegetation in regions of intensive recreation including biotopes sensitive to anthropogenic loads and especially protected areas (ESP).

The team of scientists within the Project includes specialists from the Institute of Ecology and Evolution, Russian Academy of Science (Moscow) (IPEE RAS), the State Scientific Center of the Russian Federation, State Research Institute of Chemistry and Technology of Element-Organic Compounds (SSC RF SRICTEOC) (Moscow), spetialists from the Center of Forest Ecology and Productivity (CEPF), Russian Academy of Sciences (Moscow)will also take part in this work.

The implementation of the given Project will contribute significantly to the solution of the problems of the ISTC directed to the re-orientation of scientists and engineers working before in the defence sphere. It will be promote solution of some global ecological and social problems. The changes in scientific interests and utilization of scientific and creative potentialities of Russian specialists in the interests of the international scientific comunity will promote solution of the national and international problems related to the elaboration of highly effective technologies of plant protection against deseases and antropogenic press.

Foreign collaborators may take part in the performance of this Project: participate in the discussion of the plan of the Project and ways of its implementation, in exchanging information in the course of work on this Project, in joint symposia and workshops
