A survey of the rare relict fern Botrychium lunaria (L.) Sw was conducted in one of the recently created specially protected natural areas (SPNA) in the Murmansk Region – the natural park “Rybachy and Sredny Peninsulas”. 6 cenopopulations were identified in various parts of the park. It has been shown that this species will grow in a variety of conditions both with respect to the totality of the intensity of the action of abiotic factors and with respect to the composition of the phytocenosis. It is shown that while the vitality of individuals varies within rather narrow limits and only in two cenopopulations is below 1, the density of individuals differs significantly. The results of the survey showed that when monitoring the condition of the cenopopulations of the moon-fern, it is necessary to use a set of parameters.

The paper presents a brief overview of the current state of involvement in processing of low-gradede-posits of sulfide copper-nickel oresandmining waste of non-ferrous metallurgy. Examples of foreign and Russian experience are given. A possible method for geotechnological processing of substandard sulfide ore material containing non-ferrous metals and iron is presented on the examples of objects in the Mur-mansk region. The problem of fixing dusty surfaces of the tailing dump is considered. An assessment of the possibilities of chemical coagulation for wastewater treatment is given.
