A summary
of the conclusions of the species inventory reports of the Malahvia-area
Translated and summarised by the authors of this report
Inventory
of the Beetle species of the Malahvia area, Suomussalmi
Harri Lappalainen

Research Centre of the Friendship Park
28.10.1999
Extracts:
Thirteen
nationally threatened insect species, including ten beetle species,
were found in the area studied during the field inventory season of
1999. In addition, 20 rare or quite rare beetle species of at least
30 frequency points (Silfverberg 1992 index), and one rare Scots pine-occupying
Haradus - species were found. Out of the threatened species
one is classified as Vulnerable (VU) and twelve as Near threatened
(NT).
It is
evident that the entire observed area of Malahvia sustains and supports
a rich array of species.
The most
serious threat to the biodiversity of the Malahvia area is fragmentation
of habitats brought on by logging. Even soft logging methods accelerate
the unfavourable process.
It is
reasonable to say that Malahvia is nationally a very important forest
area. The threatened species and biodiversity of insects found in
the area can only be sustained, if the fragmentation of the forest
continues no further.
The
Bird species of eastern Kainuu and their protection
Ari Rajasärkkä
Forest and Park Service 1999
One of
the methods to assess the [biological] value of a research site is
to compare the number of hole nesting birds to the total number of
bird species. In natural environments that have no artificial nests
for birds the number of hole nesting birds is a useful indicator of
how close to a natural state the forest is. This method placed Malahvia
at the very top of the list of important forest areas of the eastern
Kainuu region.
The results
of the research show that 11 examination areas in eastern Kainuu fulfil
the international Important Bird Area -criteria (IBA). Malahvia is
one of these, and first in order of importance.
Ten biomic
boreal species were found in the Malahvia area, out of which nine
on the transect line. This result is the cause of Malahvia’s top placement.
The Malahvia
area fulfills the IBA -criteria although the research area and bird
sample size are exceptionally small. This provides further proof of
Malahvia’s status as an exceptionally important bird area.
Inventory
of the Lichen species of the Malahvia area
Report
28.10.1999
Mr. Sampsa Lommi
Kainuu Regional Environmental Centre
Research Centre of the Friendship Park
Extract:
Two occurrences
of the nationally threatened lichen Evernia divaricata (NT)
were found at a distance of approximately two kilometres from each
other. The occurrence of the species at the Jäkäläaho site is exceptionally
abundant. Both occurrences are located in the vicinity of a natural
state stream. In order to preserve the species at these sites the
humidity and tree stock conditions must remain unchanged.
Inventory
of the Butterfly species of the Malahvia area
Forest
and Park Service
Kainuu Regional Environmental Centre
Mr. Reima Leinonen, 1999
Extracts:
The species
found represent typical old-growth forest species.
Judging
by the butterfly species found in the area Malahvia it is an inseparable
part of the Green Belt. To ensure the existence of old-growth forest
species it is important that the area is not logged.
