Progress of gene
conservation of Norway spruce (Picea abies Karst.) in Poland
The progress in realisation of
gene conservation of Spruce ( Picea abies Karst.) in Poland was
presented step by step at the EUFORGEN meetings in Stara Leśna
(Slovakia) and in Hyytiala (Finland). Information presented
below refer only to the last one and a half year, that is why the
progress in realisation of this programme is not so high.
Implementing our genetic
diversity conservation programme of the forest tree species for the
State Forest, we put attention on the forests belong to the National
Parks. It is only one additional gene base which can be used for
these purposes. Third important group of the Polish forests belong
to the private peoples. But as we know private forests are the least
valuable group for the gene conservation works.
To the National Parks
belong only ca. 2% of the forest land in Poland. But in fact they
are covered the most interesting and valuable parts of natural
ranges of different species (also Spruce). As famous populations,
represented for example in IUFRO 1972 experiment, as Tarnawa
Zwierzyniec Lubelski, Zwierzyniec Białowieski, Orawa and other, are
located in different National Parks. Many times was emphasised, that
for full conservation of genetic resources of Spruce, these
populations have to be included into gene conservation. The
scientists from the National Park initiate works in that field. The
„Programme of genes conservation" existing for the State
Forests was adapted for the National Parks conditions, but general
ideas and methods chosen for gene conservation of forest trees
species are the same.
For estimation the threats and
priority of action special method of classifications on the level of
genotypes, populations, species and communities was prepared.
Main modification of the
programme of gene conservation is connected with existing regulation
refer to protected area in Poland, particularly in the strict
protected areas:
- In the strict protected
areas of the National Parks only in situ conservation can be used
for gene conservation.
- This method is useful for
populations and communities living in areas where dynamic stability
exist. In situations where is lack of balance and where it is
not passable to undertake any action only ex situ conservation of
genotypes, populations, species and communities is possible.
- It will be possible to
collect the materials for ex situ conservation in strict protected
areas.
-If it would be possible ex
situ conservation will be realised in partly protected areas of the
National Parks or in State Forests.
- Ex situ conservation in Gene
Bank will be realised as an additional method of protection.
In spite of many
publications, TV and radio programmes only a small number of
specialists fully understand and accept necessity of actions in
conservation of forest genetic resources. This fact strongly limited
the scale of networks because of lack of formal regulation (special
law for gene conservation) and of course lack of money for
realisation prepared programmes an practical works in the field. To
improve this situation Forest Gene Bank from 1996 has started wide
understand ecological education. During last two years more than
3000 persons have participated in many kinds of courses, meetings,
international symposiums. Also a lot of individual peoples visited.
Gene Bank. In this year some students carried out studies for their
master thesis. (Information from Gene Bank Rapport).
Two years ago Forest Service
has started to preparing computer information system (SILP). In that
system more than 150 information relating to each plot will be
available in computer database. This system also enable us to add
new data which bring up to date the information about each plot. For
using this system for gene conservation purposes we add descriptors
proposed in Technical guidelines prepared for Spruce (Picea abies
Karst.). Only for estimation localisation in the State Forests it
will be used forest division (regional forest district, forest
district, forestry). Geographical localisation will bee estimated
additionally using GPS system. But State Forests also start to
preparing numerical forest maps. It means that using these maps and
additional equipment it will be possible to estimate geographical
position with bigger precision and can be use also for single
genotypes.
The field works in gene
conservation of spruce are presented in Tab. 1, 2 and 3). They are
concentrated manly on choosing the new populations in State Forests
and National Parks. Collection of seeds for long term storage in
Gene Bank wasn’t dane because of lack of crop in last two years.
