Revitalization of habitats

Particular management interventions are 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 was assessed to aim management interventions to this critical phase to enhance the success of their impact on plant fitness.

1.1 Suppression of competitively strong plants

a) Mowing: Mowing was introduced in parts of Želivka SCI to suppress dominant grasses (Calamagrostis epigejos and C.arundinacea). Mowing is carried out 2 times a year, on the area 3 ha. Additional 4 ha are mowed as a substitutive managament for grazing

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

c) Grazing: After obtaining permission, grazing will be introduced on part of the Želivka SCI.  

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 is 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 are thinned during this project. Some of the felled trees are 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. To supress this intensive grazing, selected rocks were fenced.  

1.5 Building of barrier for cars entry in a part of Želivka SCI for vandalism removal
Part of Želivka SCI was 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 was installed here.
