Management of the Plant and Animal Gene Funds

Management of plant and fungi species is focussed on the protection of complete ecosystems and we are not planning any cultivation programmes for individual species, with the exception of certain forest tree species (see below). We must pay attention to endangered biotope types, such as water flows, wetlands and peatbogs. The continued occurrence of many species, especially non-vascular plants and fungi, depends on us leaving sufficient dead wood in the forest stands, as well as on increasing the proportion of deciduous trees. The thorough liquidation of invasive species (Eastern White Pine, Knotweeds, Touch-me-not Balsam) plays a key role in maintaining the populations of certain native species.

Management of selected animal species is based on similar principles, although in justified cases we also strengthen the populations of endangered species or reintroduce them to the area.

Labrador Tea (Ledum palustre) grows on damp, rocky ledges in the national park.

Targets for the national park are to:

• Maintain the populations of all native species with a minimum of human intervention,
• Reintroduce species which were driven to extinction by man, if it is feasible,
• Strengthen weak and vulnerable populations of endangered animal species, if it is feasible.

Management of plant and fungi species involves:

• Protection of complete ecosystems,
• Maintaining the existing natural ecosystems (water flows, wetlands and peatbog areas, invasive biotopes, talus and ravine forests, open talus, relict pinewoods, beechwoods),
• Thorough liquidation of invasive plant species (Eastern White Pine, Knotweeds, Touch-me-not Balsam).

Management of animal species involves:

• Protecting whole ecosystems,
• Maintaining the existing natural ecosystems,
• Monitoring rare and endangered species,
• Strengthening weak and vulnerable populations of endangered animal species (Atlantic Salmon),
• Reintroducing species which were driven to extinction by man (Hazel Grouse).

Management of the forest tree gene fund:

The native gene fund of forest tree species belongs to the natural riches which require our attention and protection. The protection of these natural forest tree gene resources is influenced by the following factors:

• The high level of mixing of the gene fund from various areas,
• Problems in determining what belongs to the native local gene fund,
• The extremely high representation of Norway Spruce, which is several times higher than that of deciduous trees and firs. This is a result of the long-term cultivation of these forests, which has led to a major reduction in the gene base of native species, as well as the import of a large quantity of foreign gene resources.

Activities in the field of managing the forest tree gene fund include:

• Protecting the native gene resources (cultivation from seeds, rescue planting, active reproduction),
• Supporting and reintroducing native tree species which are greatly under-represented in comparison with the potential natural representation,
• Research focussed on determining what belongs to the native gene fund of each tree species.

Management activities are especially focussed on the Silver Fir, Wych Elm and identifying the native gene fund for the Norway Spruce, Pendunculate Oak and Sessile Oak. Suitable Silver Fir trees in the national park have been chosen as sources of reproductive material. The cones are collected by tree climbers. Approximately 400kg of reproductive material was collected from 38 trees by climbers during 2 days in 2009.
