Swamp-originating meadows constituting indirect habitats between living peatlands and classical grasslands may be difficult to evaluate. An indiscriminate application of the Oświt (2000) method for their valorization does not fully reflect their value, because of flora which is different from flora found in living peatlands (in particular, the invasion of less hygrophilous flora). Based on the research carried out in the years 2005–2010 on eight swamp-originating meadow complexes, the scale was elaborated which enabled to more accurately valorize these habitat and floristically changed areas. The quantities of valorization values obtained by use of the author’s method rely on the occurrence frequency of a given species (a number of posts in a given area), taking into consideration moisture requirements (the moisture indicator). In the author’s method values were also given for species not taken into account by Oświt (2000). In addition, positive points were given for dying out species, and negative points for invasive species.

Extending the harvesting time allows the consumers to eat fresh strawberries from the spring to the autumn. It also creates the opportunity to increase profits for the growers. However, such production requires new technologies and appropriate cultivars. Studies on extending (delaying) of the fruit harvesting period of two Polish strawberry cultivars – ‘Grandarosa’ and ‘Pink Rosa’ – were conducted at the Research Institute of Horticulture in Skierniewice (Central Poland) in 2012–2013. The productivity, fruit ripening time and fruit quality of both cultivars were assessed in the open field conditions (three dates of delayed planting, frigo potted and bare-root plants) as well as in soilless cultivation in gutters under plastic canopies and in a high tunnel (delayed planting, frigo potted plants). ‘Elsanta’ was used as the reference cultivar. It was found that delayed planting of frigo plants resulted in extending the harvest time by roughly 10 weeks in field condition and up to 12 weeks in soilless cultivation under cover. Both Polish cultivars were suitable for the cultivation in the open field and under covers for the delayed harvest. In both types of cultivation the peak of harvesting was 8 to 12 days earlier in ‘Elsanta’ as compared to ‘Grandarosa’ and ‘Pink Rosa’. The overall productivity as well as average fruit weight and fruit firmness of both Polish cultivars were significantly higher in comparison with ‘Elsanta’. The production under covers was more effective than in the open field, where the high temperatures of soil and air prevailing after planting resulted in decrease of yield and fruit quality. Moreover, plants under covers did not suffer from the early autumn frosts and they were harvested in a longer period of time as compared to plants grown in the open field.
