THE NATURE INVENTORY IN ROMUVAARA (KUHMO TOWN, NORTH-EAST
FINLAND) IN 1997
ABSTRACT

The aim of the project is to carry out the basic information for environmental impact
assessment, which started in 1997. The main goal of the project is to mitigate or prevent
the harmful impacts of the construction and maintenance of final repository of the
nuclear waste for the nature values and recreational use in the study area.

The study area cover 17,75 km2 forests and mires. The botanical and ecological
inventories consist of combination of systematic grid mapping and identification and
location the small areas with conservation value. The research included systematic
inventories of vascular plants, biotopes and selected environmental factors. Some
information concerning, mosses, lichens, polypores and recreational profits were also
obtained.

Various applications of reserve selection algorithms were used as a tool for analysing
the data base. As a result of the analysis, every grid unit was calssified according to the
importance for biodiversity in level of the study area. After that, ecological priority areas
were identified. The selected areas represent the highest diversity of vascular plants and
biotopes in the study area. The key biotopes and other areas with high conservation
value were demarcated.

The landscape of the Romuvaara area is characterized by commercial pine forests, partly
drainaged bogs and swamps. Eskers, herb-rich and temporary flooded brook corridors,
lakes and ponds, nutrient rich springs as well as mires are also common. The cultural
landscapes virtually absend, except the forest road network.

No populations of nationally endangered species were found in the study area. Of the
provincially threatened species, two vascular plants in need for monitoring were
detected. Moreover, numerous rare or otherwise notable vascular plants, mosses and
polypores were observed. Particularly the flora of nutrient rich wetlands is rich. Many
small areas with high conservation value were identified and located, expecially nutrient
rich swamps and sprins or brook corridors. Five larger areas with high biological value
were formed as a result of the combination of the small areas. The most important larger
area includes the Särkkä esker and the wetlands in its vicinity.
