Organization and implementation of the long-term monitoring, has always been an advantage of science parks. In the Polistovsky Reserve, this program is executed according to the current capabilities and adapted to the Reserve. In monitoring the ecosystem it is quite sufficient to carry out systematic studies of individual biological objects and factors of influence. This monitoring involves the examination of changes in the composition and structure of biocenoses, as well as changes in the number and placement of individual species of plants and animals.
The main objects of monitoring in the Polistovsky Reserve are groups of species of plants and animals, reflecting the general state of the ecosystems of the specially protected natural territory. Currently, systematic long-term observations include the following biotic parameters of wetland ecosystems:
- monitoring of raised bog vegetation;
- monitoring of succession in areas disturbed by fire;
- yield of cranberries as well as other berries, mushrooms and nuts;
- monitoring of populations of small rodents and insectivores;
- winter route recording of hunting species (WRR);
- monitoring of bird communities in forest and wetland ecosystems;
- Monitoring of zooplankton in reservoirs and streams of the Reserve and surrounding areas.
In addition, there is a monitoring of abiotic components of ecosystems, mainly a hydrological one:
- monitoring of wetland water level fluctuations;
- monitoring of the depth of freezing and thawing of the raised bog system;
- monitoring of snow cover.
Monitoring results show that natural complexes of the Polistovsky Reserve are in a stable good condition. Observed minor fluctuations in wetland vegetation are associated with differences in year weather conditions. In forest coenoses one can observe successions - replacement of primary small-leaved forests by primary boreal and spruce-deciduous forests. The population dynamics of mammals and birds is low; it is a reflection of natural processes in populations occurring in the region.
