Woody plants in the Zlatý kůň territory

First woody plants began to spread within the territory of Zlatý kůň after the last Ice Age ended, that is, in last 10 000 years. The territory was by a patchwork of dry bright groves with little isles of steppes covered. In the Middle Ages began it to deforest, which continues till these days. A natural forest cover can be found today only on the northern hillside of Zlatý kůň. European hornbeam (Carpinus betulus), sessile oak (Quercus petraea) and European beech (Fagus sylvatica) prevail here. With the removal of the original cover of woody plants an opportunity for other species of woody plants, which could begin to spread here, opened in the territory of Zlatý kůň. The task of contemporary conservationists is it to regulate the development of the wood plants composition in such way that the biodiversity of the territory does not decline. The original plant species which were until recently especially by pasture repressed pervade into the broadleaf thermophilic lawns. These woody plants – blackthorn (Prunus spinosa), common dogwood (Cornus sanguinea) and dog rose (Rosa canina), are today as a threat for many rare steppe herbs species seen, which cannot survive under the brush. They belong to the kind of transient biotope between steppe lawn and wood, that is to the forest-steppe type: whitebeam (Sorbus aria), common cotoneaster (Cotoneaster integerrimus), common hawthorn (Crataegus monogyna) or european cornel (Cornus mas). Common juniper (Juniperus communis), which is today here and there scattered on the steppe lawns, is a witness to earlier overgrazing.
At least welcome are here geographically unoriginal woody plants which pervade spontaneously or were here planted out in the past with a good intention. In the national natural monument Zlatý kůň are these especially the black locust (Robinia pseudacacia), originally from North America, and the European black pine (Pinus nigra) whose homeland is southern Europe. Such species are able to replace the original composition of plant formation and completely change the face of the landscape. These species are then as so called invasive species marked.
