Facilitation or competition occurs among plant species when one alter ameliorates the environment for another needs same sources of species. The objective this study was to determine facilitative competitive effect on Bromus variegatus, Festuca ovina, Koeleria cristata growing with isolated, Medicago papillosa, Astragalus microcephalus, Thymus parviflorus, and Hypericum scabrum, arranged in com...

Vegetation recovery in severely disturbed alpine ecosystems can be accelerated through active restoration measures. This study evaluated the short-term effects of two treatments, planting propagated native Salix (willow) shrubs three different densities (1, 2.5, and 4 plants/m2) seeding grass Festuca ovina (sheep fescue), a heathland. We natural vegetation (i.e. cover, vascular plant species ri...

Stored seeds deteriorate over time and must be regenerated to ensure that the benefits of ex situ conservation are realized. Prediction of seed longevity is based on the seed viability equation. This equation has four constants which are species specific. The aim of this project is the estimation of these constants and prediction of regeneration frequency for Elytrigia elongata, Dactylis glomer...

Due to the decreasing trend of rangelands, many native species are vulnerable and even at risk of extinction. Therefore, seed preservation and propagation of native species of rangelands and recognition of the characteristics of grazing, drought tolerance and their production potential are very beneficial. In this study, the five species of Festuca ovina, Festuca rubra, Br...
