“…Even though the habitat categorisation was broad, our results clearly indicate that there are several habitats other than grasslands harbouring butterflies. Similarly, Berg et al (2011) demonstrated that several typically overlooked habitats in forest-dominated landscapes can have at least as high numbers of butterfly species as semi-natural grasslands. Thus, it is evident that systematically placed transects throughout the country can be an important consideration in order to reduce bias in habitat coverage.…”

Nature Conservation 14: 41-62. doi:10.3897/natureconservation.14.7497 AbstractButterfly monitoring schemes are recording programs initiated to monitor nationwide butterfly abundance and distribution patterns, often with help from volunteers. The method generates high-resolution data, but may be associated with a degree of habitat sampling bias if volunteers prefer to survey areas perceived to be high-quality butterfly habitats. This can result in habitats becoming underrepresented in the data set, leading to less information about the butterfly populations there. In the present study, we investigate the possibility of applying a spatial design used by the Swedish Bird Survey for nationwide, gridbased sampling, with a goal to get butterfly monitoring data covering a representative sample of different habitats. We surveyed four 2×2 km sampling squares, split into 100 m segments, in the southernmost region of Sweden (Scania) and four in the northernmost region (Norrbotten). The grid-based transects were compared with volunteer-selected transects in a GIS analysis using a refined Swedish version of CO-RINE land cover data to see how well these two transect designs represent true habitat coverage. A total of 53 km transect was monitored, resulting in 490 individuals and 29 different species recorded. We found that transect cover correlated significantly with overall land cover using both monitoring methods, though standardised transects outperformed volunteer-selected transects in habitat representation in Scania, but not in Norrbotten. Butterflies were found to aggregate significantly in specific habitats, but with contrasting results for the two geographically different regions. Grasslands in both regions generated a high number of recorded butterflies, although so did clear-cut and residential areas in Norrbotten as well. The

“…For example, the density of plant species commonly exceeds 40 species/m 2 [41,42]. In addition to plants, these grasslands are hotspots for many different taxa [43], including fungi [44] and butterflies [45]. Large broad-leaved trees in semi-open woodlands are hotspots for epiphytic lichens [46] and insects [47].…”

“…(2) Road verges and other constructed linear grassland landscape elements, if properly managed, may harbor plant species otherwise dependent on semi-natural grasslands and grassland-forest mosaics [99] and enhance the dispersal of these species [84]. Such linear grasslands have also been found favorable for butterflies [45,100]. However, road verges are also favorable for several invasive plants, for example lupines (Lupinus polyphyllus).…”

Conceptual advances in niche construction theory provide new perspectives and a tool-box for studies of human-environment interactions mediating what is termed anthropogenic biomes. This theory is useful also for studies on how anthropogenic biomes are perceived and valued. This paper addresses these topics using an example: "old cultural landscapes" in Scandinavia, i.e., landscapes formed by a long, dynamic and continuously changing history of management. Today, remnant habitats of this management history, such as wooded pastures and meadows, are the focus of conservation programs, due to their rich biodiversity and cultural and aesthetic values. After a review of historical niche construction processes, the paper examines current niche construction affecting these old cultural landscapes. Features produced by historical niche construction, e.g., landscape composition and species richness, are in the modern society reinterpreted to become values associated with beauty and heritage and species' intrinsic values. These non-utilitarian motivators now become drivers of new niche construction dynamics, manifested as conservation programs. The paper also examines the possibility to maintain and create new habitats, potentially associated with values emanating from historical landscapes, but in transformed and urbanized landscapes.

“…As a corollary, the 'optimal' management appears highly group-specific, and for conserving cross-taxonomic species richness, diversifying management regimes has hence repeatedly been recommended (e.g. Baur et al 2006;Berg et al 2011;Sjödin et al 2008).…”

“…Saarinen and Jantunen 2005;D'Aniello et al 2011). These partly contradictory findings may result from differences in mowing dates and frequencies or from variation in the response of individual butterfly species to different management regimes (Berg et al 2011;Bubová et al 2015). One might hence assume that, like in the case of crosstaxon diversity, the best way to maximize butterfly species richness in a large grassland ecosystem should be a diversification of management regimes (Botham et al 2015).…”
