    Grönlands växtvärld2012In: Svensk Botanisk Tidskrift, ISSN 0039-646X, Vol. 106, no 1, p. 11-23Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    Flora, vegetation and land-use history of Greenland are briefly described. The species-poor flora is Arctic. Thirteen endemic taxa may have survived the glacial period on Greenland.

    The latitudinal vegetation zones extend from High Arctic deserts to Low Arctic heaths with erect shrubs. A small area in the SW is Subarctic with elfin forests and meadows. A corresponding altitudinal zonation is also described.

    Greenland was colonised 1000 years ago by both Inuits and Norse settlers. The latter practised animal husbandry in the Subarctic SW. Hay-making was extensive on fertilized and irrigated fields. Extensive deforestation and land degradation took place, until the Norse population disappeared in the 15th century. It is argued that the decreasing population on Iceland during late medieval times made it possible for the Greenlandic Norse to move there. Modern sheep holdings have again caused land degradation. Notes on small-scale forest plantation and on ethnobotany are given.

    Remnant habitats for grassland species in an abandoned Swedish agricultural landscape2010In: Applied Vegetation Science, ISSN 1402-2001, E-ISSN 1654-109X, Vol. 13, no 3, p. 305-314Article in journal (Refereed)
    Abstract [en]

    Questions: Which factors influence the persistence of vascular grassland plants in long-abandoned (at least 50 yr) arable fields and meadows? What might be the implications of current levels of species richness on abandoned arable fields and meadows for future restoration?

    Location: Forested highlands of Kilsbergen, south central Sweden.

    Methods: The abundance of all vascular plant species was investigated in three habitat types: former arable fields, hay meadows and outlands (pastures) at 27 farms, abandoned for either approximately 50 yr or 90 yr. Time since abandonment, tree cover, soil depth, degree of soil podsol development, size of the infield area and two measures of connectivity were used as predictors for species richness and species composition.

    Results: Former outland had denser tree cover, fewer species and fewer grassland species than former arable fields and hay meadows, irrespective of time since abandonment. Former hay meadows and arable fields with a longer time since abandonment were less rich in species, more wooded and had greater podsolization than meadows and fields abandoned at a later stage. Species richness was higher in hay meadows and arable fields at farms with larger infield area and deeper soils compared with farms with smaller infield area and shallower soils. The greatest richness of species and most open habitat were former arable fields at larger farms abandoned 50 yr before the study. Former arable fields had the highest number of grassland species.

    Conclusion: After 50 yr of abandonment, former arable fields were the most important remnant habitats for grassland species and may be a more promising target for restoration than formerly managed grasslands.

    "They Followed The Power Of The Plant'': Historical Sami Harvest And Traditional Ecological Knowledge (Tek) Of Angelica Archangelica In Northern Fennoscandia2016In: Journal of Ethnobiology, ISSN 0278-0771, E-ISSN 2162-4496, Vol. 36, no 3, p. 617-636Article in journal (Refereed)
    Abstract [en]

    Native Sami people in northern Fennoscandia have used a wide range of native plant species for food and medicines throughout history. Plants and plant use are deeply embedded in the Sami traditions and subsistence in northern ecosystems. The overall aim of this study was to gain understanding of the Sami people's interaction with the herb Angelica archangelica in historical times and investigate if this use went beyond a pure opportunistic harvest of wild plants to include management of plants. To analyze this question, we combined studies of ethnographic information, an experimental field study, and discussions with a Sami woman with extended knowledge of Sami plant use. We suggest that the Sami people had a profound understanding of the complexity of the plant life-cycle. They dispersed seeds to favored areas and used harvest techniques intended not to deplete plant populations. The harvest experiment shows that it is possible to prolong the plant's life span by repeatedly harvesting infertile plants. A cross-disciplinary approach is needed to expand understanding of past plant use. Our results place overall Sami subsistence practices in a new light, as being cared for, managed, and sustainable.

    Planetary Stewardship in an Urbanizing World: Beyond City Limits2012In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 41, no 8, p. 787-794Article in journal (Refereed)
    Abstract [en]

    Cities are rapidly increasing in importance as a major factor shaping the Earth system, and therefore, must take corresponding responsibility. With currently over half the world's population, cities are supported by resources originating from primarily rural regions often located around the world far distant from the urban loci of use. The sustainability of a city can no longer be considered in isolation from the sustainability of human and natural resources it uses from proximal or distant regions, or the combined resource use and impacts of cities globally. The world's multiple and complex environmental and social challenges require interconnected solutions and coordinated governance approaches to planetary stewardship. We suggest that a key component of planetary stewardship is a global system of cities that develop sustainable processes and policies in concert with its non-urban areas. The potential for cities to cooperate as a system and with rural connectivity could increase their capacity to effect change and foster stewardship at the planetary scale and also increase their resource security.

    Mowing for biodiversity: grass trimmer and knife mower perform equally well2014In: Biodiversity and Conservation, ISSN 0960-3115, E-ISSN 1572-9710, Vol. 23, no 12, p. 3073-3089Article in journal (Refereed)
    Abstract [en]

    Mowing of semi-natural grasslands is an important management method to maintain the conservation value and species-richness of this habitat. Mowing using cutting instruments, e.g. sickle bar mowers, is thought to be superior by practitioners compared with other mechanical instruments that tears off the plant material, e.g. grass trimmers. However, almost no studies exist that supports this assumption. We analysed a 12-year field trial in a semi-natural grassland in south-eastern Sweden, with the aim of determining which mowing technique best maintains the conservation value of semi-natural grasslands. Two mowing techniques were compared: mowing using a hand-pushed sickle bar mower (a type of knife mower), or mowing using a grass trimmer at a 5-cm or 0-cm cutting height. The odds that a recorded species belongs to a group of indicator species were calculated for sample plots, and odds ratios were calculated contrasting treatments. Three types of indicator species classification systems were used: (i) indicators of management for species richness, (ii) indicators of excess nitrogen and (iii) indicators of lack of management. The odds ratios were calculated for years 1-5, 7 and 12 of the trial. In addition, Principal Response Curve analysis was performed to analyse the change in vegetation composition over time and ANOVA for plant species richness in plots. The results showed that over time there were no differences in the odds of finding indicators of any of the three types, for any of the mowing techniques. Furthermore, there were no apparent change in vegetation composition and only a small effect on richness. These results suggest that mowing using a sickle bar mower or a grass trimmer had the same effect on the floristic composition of grasslands, and both techniques can be recommended for use in semi-natural grasslands.
