Revitalization of habitats

Particular management interventions will be implemented on the basis of mapping of Minuartia smejkalii distribution and habitat quality not to destroy plant bunches. The critical phase of the life cycle will be assessed to aim management interventions to this critical phase to enhance the success of their impact on plant fitness. On each site several permanent plots will be marked for evaluation of project impact on habitat quality and vitality of particular populations.

Management interventions will be very intensive and they will require subsequent regular interventions such as mowing, grazing and removing of self-seeding trees. These interventions will not enhance soil erosion above the natural erosion of serpentine rocks.

By clicking on   particular actions you can follow the progress in their implementation and look at photos.

1.1 Suppression of competitively strong plants

a) Mowing: Mowing will be introduced in parts of Želivka SCI that have not been mowed regularly and there are extensive monodominant stands of grasses (Calamagrostis epigejos and C.arundinacea). Mowing will be carried out 2 times a year, i.e. before the seeds ripening and before the end of the growing season.

b) Manual removal of expansive plants: On parts inaccessible to machinery competitors will be removed manualy. Removed plants will be mainly (Vincetoxicum hirundinaria) , mosses, bunches of Sarothamus scoparius,  expansive grasses.

c) Grazing: After obtaining permission, grazing will be introduced on part of the Želivka SCI.  Before grazing, this part will be mown to remove biomass.

d) Supression of Calamagrostis epigejos by sowing of Rhinanthus alectorolophus. Rhinanthus is hemi-parasitic plant species, which parazities on species from family Poaceae and thus decrease their growth. If Rhinanthus has not suitable host plant, it disapears from locality. 

1.2 Removal of humus layer

M. smejkalii is bound to serpentine substrate, so accumulation of humus layer or changing soil chemistry leads to its suppression. For this reason, on selected sites with high humus layer or acidic litter, mechanical removal of this layer will be done.

1.3 Suppression of negative effect of forest management
As a result of forestry and natural regeneration of vegetation, dense forests of pine, spruce and other trees occurs on some parts of both sites. These dense parts will be thinned during this project. Some of the felled trees will be left in place for the development of insects on both SCI areas.

1.4 Reduction of intensive grazing
On one part of Želivka SCI almost all individuals of M.smejkalii were devastated by grazing by large herbivores (deer, hare, moufloms), leading to great reduction of produced seeds. Because of steep and rocky terrain, it is not possible to install fences on each rock. Most of grazed plants occurs on the border of locality, which neighbor with agriculture forest and are not too steep. For this reason, we will fence only these parts, which are easy accessible for animal.

1.5 Building of barrier for cars entry in a part of Želivka SCI for vandalism removal
Part of Želivka SCI is threatened by illegal dump because of its close proximity to the asphalt forest road and easy access of locals. To prevent the entry of cars to this place, a barrier with a lock bolt will be installed here. Simultaneously with the construction of the barrier, we will focus on enhancement of awareness between locals.
