Organization of monitoring of plant cover during the development of deposits of precious metals using the example of objects of the Malmyzh ore field

Using the example of the Malmyzhskoe porphyry copper ore deposit, a system for monitoring the state of plant cover during mining and related subsoil development activities has been developed. The purpose of monitoring is to obtain objective information about the dynamics of species diversity, plant communities, populations of valuable, rare and endangered plant species, to identify trends in these dynamics for the timely development and implementation of measures aimed at eliminating or mitigating problems that arise during the operation of the facility. By the beginning of the development of the field, the indigenous forest formations of the territory had already been largely disturbed as a result of logging and fires and were especially vulnerable to various types of impacts. This determines the relevance of the ongoing monitoring studies organized in this territory. The proposed system of monitoring bioindicator objects includes several levels: coenotic (at the community level); species diversity (at the level of partial floras); species (at the level of local populations of bioindicator plants); information (databases and geographic information systems). On the territory of the deposit facilities, diversity was identified and the current state of plant communities, cenopopulations of rare and endangered plant species was assessed, and their monitoring was organized. Information and geoinformation databases have been developed.
