Collected dataCollected data
On terrestrial and inland water areas that were or are formally protected since the 1900th
The database includes: - name of a PA - national designation to a particular category - location (northern, middle or southern boreal forests) - size (in ha) - year of designation - year of conversion of a PA to other type of PA or unprotected
area - IUCN management category Identified a total of 17 086 PAs

ResultsResults
The total PA in Europe’s boreal forest increased steadily from the 1900th to the 2010th
However, there was considerable variation in dynamics among different decades and northern, middle and southern boreal forests
During eight decades out of ten the main growth in the total area of PAs took place in the northern boreal forest
ResultsResults Strict nature reserves (I) and national parks (II)
were the main categories of PAs’ during the first four decades
Their area proportion sharply declined in the 1960s The current ‘set’ of PA categories was established in
the 1970s The area proportions for current PAs’ management
categories have been relatively stable since the 1990s

ResultsResultsThe median size of PA: 124 ha in Russia 64 ha in Sweden 48 ha in Norway 10 ha in Finland
ConclusionsConclusions
The existing PAs shows a poor representativity among the northern, middle and southern boreal forests since the beginning of 20th century.
As a result, by the end of 2010 the area proportion of PAs was 10.8% of the total boreal forest area in Europe with 17.2% of the total area of northern, 7.9% of the middle and 8.7% of the southern boreal forests.
ConclusionsConclusions The uneven representativity of PAs in Europe’s boreal biome
and each country that was maintained during almost the entire century has been and is a big challenge for boreal biodiversity conservation today
Another challenge: the vast majority of boreal PAs are small in size, with the smallest areas in the southern boreal forest
The area proportion of protection is an important indicator for conservation efforts; however, it does not necessarily mean that PA networks are in place in terms of providing functional habitat networks for different ecosystems, or for ecological sustainability.
