Keywords orchard meadows; vegetation; scattered settlements; management; syntaxonomy; diversity; Myjava hilly land; White Carpathians Introduction Traditional old orchards are one of the most valuable and endangered habitats of the European cultural landscape [1]. Te fruit tree and grassland undergrowth subsystems combine conditions of both forest and non-forest habitats and they are known for their high biodiversity [2–5]. Tey are important in maintaining old local fruit tree varieties Published by Polish Botanical Society 1 of 16 Žarnovičan et al. / Grassland communities of orchards in Western Carpathians (Slovakia) [6]. Te grassland undergrowth protects the soil against erosion and positively afects its physical and chemical properties [7–9]. Tis provides an excellent example of tradi- tional European agroforestry systems as well as olive orchards, wood pastures, dehesa and montado (cf. [10]), which were and are still used in Europe [11]. Nowadays, their importance is increasing in order to maintain biodiversity in the cultural landscape [10]. Orchard meadows form part of the landscape in most countries in Western, Central, and Eastern Europe. Although traditional orchards are ofen under-utilized compared to the past, they still thrive in Germany, Spain, France, England, Poland, Czech Republic, Slovenia, and Ukraine [6,12,13]. Tese persist despite the dramatic loss of traditional orchard meadow area during the second half of the twentieth century recorded in southwestern, southern, and eastern Germany [13–15], Switzerland [6], Austria [16,17], France [18], and Slovenia [19,20]. Here in Slovakia, Špulerová et al. [21] report that 70.25% of traditional orchard landscape is threatened by abandon- ment of traditional farming and this has now become one of the greatest threats to traditional orchards. Biodiversity in the European agricultural landscape has also been severely afected by agricultural intensifcation with ensuing landscape simplifcation and biodiversity loss [22–24]. Agricultural collectivization also played an essential role in former socialist countries, where small felds were merged into large blocks under uniform management. Tis had negative impact on orchards in the study area [1,25] where part of traditional orchards disappeared and some intensively managed large- scale apple and plum orchards were established in the 1970’s. Te fall of socialism in Eastern and Central Europe then caused decreased management intensity, and even its cessation in some areas [26]. Te Slovak orchard meadows have a specifc type of land use typical for regions with scattered settlement called “kopanice”, which are present throughout the Myjava hilly land and White Carpathians. Tis settlement type expanded from the second half of the sixteenth century in poorly accessible forested areas [27]. While the main function of traditional orchards was fruit production in the past, today it is their nature that is highly valued rather than economic importance because they serve as biodiversity hotspots and contribute significantly to cultural landscape diversity [12,28]. The small-scale orchards with 0.5-hectare average area produced mostly plums and apples with fewer pears, cherries, common walnuts, and rarely, even true service trees. Te undergrowth was used for grazing and producing hay and some orchards were used to grow vegetables and grain. Traditional management usually included biannual mow- ing and 1–3 head of cattle, sheep, or goat grazing per orchard. Tree litter was removed annually, usually in spring, and although orchards were fertilized with manure and slurry, chemical spraying of trees was rare [29]. Te frequency and intensity of traditional orchard management has decreased in Slovakia over the last 25 years [21,29] as in other European countries [6,12,30]. Tis trend threatens not only their functions but their very existence. Management of intensive orchards has also changed in the study area, and while most have been gradually abandoned following the 1989 sociopolitical changes, some are still in use. Because grassland diversity depends on long-term regular management [31–33], it is therefore necessary to maintain orchard meadow biological values by ensuring traditional management continuity and traditional ecological knowledge. Tis entails combining elements of theoretical knowledge and the practical experience and beliefs [34] which are eroding today. Maintaining traditional ecological knowledge is obliga- tory to protect countryside landscape efectively [35]. Te study of orchard meadow plant communities helps us understand the impact of various management regimes on their species composition. While phytosociological research of orchard meadows in Europe was mainly per- formed in Germany [36–39], some information on the occurrence of this habitat is also reported from other Central European countries [6,10–12] but phytosociological data is lacking or poorly accessible. In Slovakia, foristic and vegetation research of orchard meadows has only been partly carried out and historical data is relatively missing. Te most important papers focused directly on the study area orchard meadows were published by Ružičková [40] (50 relevés) and Labuda and Žarnovičan [1] (13 relevés). Te detailed research of subxerophilous and mesophilous grasslands of the White Carpathians dealt partly
