The Bílá Lhota Park NNM exists to protect the arboretum around the former chateau in the village of Bílá Lhota, in the Olomoucký kraj – Olomouc Region. The monument was declared in 1969 and covers an area of 2.41ha.
The park in Bílá Lhota belongs to the geomorphological unit of the Zábřežská vrchovina Hilly Country and the Bouzovská vrchovina subunit. The park lies at elevations of 287-297 metres above sea level. The geological basement of this territory is built of rocks of the Lower Carboniferous Period. The soil covering is of deep or very deep loamy Cambisols.
The park contains a dendrological collection of exceptional significance, most of which was planted in the period up to the middle of the 20th century. Since 1969 the arboretum has been regularly planted with new tree species. At present we can find around 300 tree species in the park, including their sub-species, cultivars and varieties.
The original chateau park was founded around the year 1700, when it was dominated by domestic tree species. The present appearance of the park is especially due to Quido Riedl, who worked to build up the tree collection here between 1926 and 1940. To form the core of the park he used English oaks (Quercus robur), red oak (Quercus rubra), red-leaved beech (Fagus sylvatica “Atropurpurea”) and common beech (Fagus sylvatica). The core trees among the conifers are common yew in the form of seven varying cultivars (Taxus baccata). The cypress order (Cupressaceae) is well represented and the collection also includes valuable spruces (Picea sp.div.) and firs (Abies sp.div.).
Other interesting tree species in the park include Japanese yew (Taxus cuspidata), swamp cypress (Taxodium distichum), eastern hemlock (Tsuga canadensis “Pendula”), a unique bush-sized cultivar of the white cedar (Thuja occidentalis “Umbraculifera”) and the Siberian dwarf pine Pinus pumila. Among the more notable deciduous trees in the arboretum we can mention the Lebanon oak (Quercus libani), umbrella magnolia (Magnolia tripelata), Chinese necklace poplar (Populus lasiocarpa), Chinese cork tree (Phellodendron chinensis) and the Chinese angelica tree (Aralia chinensis). The arboretum also contains collections of witch-hazels (Hamamelis sp.div.), beeches (Fagus sp.div.), Japanese maples (Acer sp.div.), rowans (Sorbus sp.div.) and decorative apple trees (Malus sp.div.).
The herb layer has never been the subject of a detailed inventory, but the park contains large numbers of grasses, ferns, perennials etc. We can see large carpets of snowdrops (Galanthus nivalis) in the park in early spring, as well as spring snowflakes (Leucojum vernum), hepatica (Hepatica nobilis), lily of the valley (Convallaria majalis) and meadow saffron (Colchicum autumnale). The beautiful growths of ostrich ferns (Matteucia struthiopteris) will also catch our eye when we visit the park.
The only fauna group which has been researched is the birds. Between 1998 and 2000 a total of 57 bird species were recorded here, of which 47 are also nesting species.
