E‐mail :seni j a＠ lsinter .netKey words : grassland ,grassland management ,botanical compositionIntroduction Plant communities and their botanical composition are determined by environmental factors and management .Different climate , topography and extensive system management contribute to flora and fauna diversity of Bosnia andHerzegovina grasslands . Any changes in management or soil conditions ( within the same or different environments ) lead tochanges in botanical composition of the sward . That is why different plant communities and different botanical composition ofthe sward can be found in significantly small areas . Even cessation of grassland management for a few years causes increases intall grasses ,shrubs and woody plants species as well as disappearance of orchids from grasslands ( Fisher and Rahmann ,１９９７) .The aim of this study was to determine differences between botanical composition and species richness of the swards on one sideand various soil types on the other .Materials and methods We studied a grassland site in a hilly region (２５０m above the sea level) ,situated on a slope with differentsoil types as follows : (１ ) deep ,silt clay loam ,with pH of ５ .１ ; ( ２) shallow calcareous with pH of ７ .０ and ( ３) brown soil withpH of ６ .１ . This grassland site had been used many years before as arable land ,later as grassland and was then almostcompletely abandoned . The most representative plants on deep soils were Rubus f ruticosus and Rubus idaeus . Shallowcalcareous soils were covered by grasses ,shrubs and small trees ,while the grassland site on the brown soil consisted of grasscover and a lot of small orchard trees . During the summer and early autumn １９９８ shrubs and small trees were cleared . Aftercutting ,the grassland site with deep soil was sown whereby the two other parts were burned . During the following eight years(１９９９‐２００６) ,the whole grassland site ( ０ .２ ha ) was selectively defoliated . Botanical composition was recorded by Braun‐Blanquet method .Results Botanical composition of the grassland site indicates ( with the same management ) a decisive influence of soil type andsoil conditions on botanical structure of the sward related to water potential and pH . Due to better water capacity and low pH ,botanical composition of sward with deep ,silt clay loam soil ,contained many plants species which are characteristic of fields andmeadows ,like Stellaria media ,Glechoma hederacea , Taraxacum o f f icinale , Heracleum sphondy lium Festuca p ratensis ,Dacty lis glomerata ,Lolium italicum ,Lolium perenne , and very acid soils i .e .Dryop teris f ilix‐mas andPteridium aquilinum .Botanical composition of the second part consisted of plant species that grow on very dry and poor soils ,or poor calcareoussoils . Within these areas ,the most abundant species are Peucedanum coriaceum , andPeucedanum oreoselinum , but there arealso Sedum acre ,H ieracium p ilosella ,Carlina vulgaris ,H y pocheris radicata . Especially valuable species found on this partare orchids (Orchis p allens ,Orchis simia ,Orchis purpurea ,Ophrys ap i f era ,Ophrys insecti f era ,Ophrys sphecodes ,Orobanchegracilis ,Orobanche teucrii ) and some other rare and endangered plants coriaceum , Peucedanum oreoselinum , Thymusserpy llum ,Heracleum sphondy lium ,Festuca p ratensis ,Dacty lis glomerata ,T ri f olium p ratense and many other plant species .The most common species for the whole grassland site was Brachy podium sy lv aticum . Poor botanical composition at thebeginning became richer during the study period due to management . The most species were found in the third year ( ７６ ) andless (６３) in the first part of the study . The most grass and legume species were also found growing onthe brown soil with pHof ６ .１ .Conclusions With the same management and environmental conditions ,soil type with pH have a decisive effect on botanicalcomposition and species richnesss on grasslands . In general ,biodiversity and especially number of valuable species are increasedon neutral and calcareous soils .ReferencesAlibegovic‐Grbic ,S . ,Custovic ,H ( ２００２) Some measurement in changing botanical composition and increasing of biodiversity ongrasslands .
