This study compared the forage quality of Festulolium entries of festucoid (Hykor) and loloid attributes (Felopa and Norwegian candivars) with major cultivars of the parent species perennial ryegrass and meadow fescue, and with timothy. Forage NDF, iNDF, kdNDF and DDM were analysed at vegetative stage, early heading, heading and anthesis during spring growth (SG) and two subsequent regrowths over two production years at two locations in Norway. NDF and iNDF increased and kdNDF and DDM decreased with advancing maturity, mostly expressed in SG, with negative correlations between DDM and NDF and iNDF and ADL and strong positive correlations with kdNDF. In SG, across years and locations, the content of NDF at heading stage was 30% higher and iNDF 400% higher in stems than in leaves, while stem kdNDF was about 50% of that in leaves. In general, timothy cv. Grindstad and Festulolium cv. Hykor had the highest NDF and iNDF and the lowest kdNDF values. Loloid entries of Festulolium were quite similar to perennial ryegrass, although the tetraploid entry proved better than the others with respect to forage quality. Regarding nutritive value, the festucoid and loloid types of Festulolium should be considered separate groups. The effect of year was more pronounced than that of location, for which the ranking of entries was quite similar. Loloid Festulolium is prone to winter damage and, although it has higher nutritive value than the parent species, its use will depend on the conditions for winter survival.

Public participation in landscape planning and management has received increased attention acrossEurope since the European Landscape Convention (ELC) came into force in 2004. The ELC has now beenratified by many countries, which have been working on its implementation for up to several years. In thisarticle, we study experiences from public participation in five different planning processes in Norway,and we assess the methods used according to a set of evaluation criteria developed in a European context:Scope, Representativeness, Timing, Comfort and Convenience, and Influence. Subsequently we identifyten singular methods as being particularly effective in terms of contributing significantly to increasingscores of Scope, Representativeness, and Comfort and convenience, i.e. the criteria most influenced by themethods chosen. All ten methods identified contribute to increase scores on one or two evaluation crite-ria, which underlines the importance of combining different methods to achieve effective participationwithin the restricted framework of a concrete spatial planning process. In an international perspectiveit seems most fruitful to apply a set of both dominantly verbal methods as practiced in Norway andsomewhat more visual approaches used in other countries. This would also acknowledge basic differ-ences among theoretical understandings of landscape and follow a recent scientific development of theconcept of landscape.
