Opis:
Restoration is a well-known and commonly used active and/or passive protection procedure that is aimed at restoring the original habitat conditions. The choice of restoration methods is closely related to the properties and conditions in a given habitat. The scope of activities carried out as part of the restoration procedure is selected in such a way so as to intervene in the natural environment as little as possible and bring the best results. Such activities are commonly considered difficult to implement and burdened with significant costs, while their usefulness is low. However, practice shows that it is possible to undertake restoration activities at low costs and with positive effects that are visible in a relatively short time. The restoration of valuable hydrogenic habitats, such as the mountain fens of the Caltho-Alnetum community in the Babia Góra massif is a great example here. The performed restoration activities proved that with minimal intervention in the environment, with the use of natural local materials or the application of extensive forms of utilisation, the condition of these habitats was improved, the degradation processes were stopped and their natural functioning was restored.

Opis:
The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field.
