Re-establishment rate of reindeer lichen species following conventional disc trenching and HuMinMix soil preparation in Pinus-lichen clear-cut stands: a survey study in northern Sweden

Effect of stump size and timing of stump harvesting on ground disturbance and root breakage diameter

“…These are far higher proportions than those reportedly caused by mounding (14-21%; Roturier and Bergsten 2006), which is the most common method of preparing soil for spruce stands (Rantala et al 2008;Hallongren et al 2014). However, similar proportions are reportedly disturbed by disc trenching Roturier et al 2011). The percentages of ground disturbed in the present study after stump harvesting and mounding were 59-61%.…”

“…It is therefore interesting to compare ground disturbance after stump harvesting to that after various possible kinds of soil preparation, including mounding, which is the most commonly used soil preparation method after stump harvesting in Finland (Rantala et al 2010;Hallongren et al 2014). For example, 14-21% of the total area is disturbed after mounding and 40-60% after disc trenching (Roturier and Bergsten 2006;Roturier et al 2011).…”

The decreasing availability of reindeer forage in boreal forests during snow cover periods: A Sámi pastoral landscape perspective in Sweden

“…In particular, the problem of the reduced availability of forage during snow cover periods could be more comprehensibly understood and addressed if sustainable land use planning at local, regional and even national levels adopted the Sámi pastoral landscape perspectives of RHCs, and focussed on incorporating the multiple ecological scales identified in the two aforementioned overlapping ecological dynamics into decision-making processes. The academic literature has already put forward many concrete suggestions on how lichen habitat formation and sustenance could be promoted at the scale of forest stands (increasing rotation time, reducing soil disturbance, leaving larger groups of trees, considering efficient dispersal distances, more vigorous early thinning, lichen transplantation) and at the landscape scale (preserving large continuous old-growth forest and increasing the area and connectivity of non-use forest areas) (Kivinen et al 2010 ; Roturier et al 2011 ; Korosuo et al 2014 ; Horstkotte et al 2016 ; St John et al 2016 ).…”

Abundance and accessibility of forage for reindeer in forests of Northern Sweden: Impacts of landscape and winter climate regime

“…This can reduce lichen cover and biomass by up to 70%, even 15 years after soil preparation has taken place (Roturier et al, 2011), although the severity of these impacts vary (Roturier & Bergsten, 2006). Earlier studies have shown that alternative forestry methods involving less soil disturbance, such as winter harvesting or using gentler forms of scarification compared to the conventional disc trenching, can significantly reduce both the loss of lichen and increase its rate of recovery from disturbance (Coxson & Marsh, 2001; Roturier et al, 2011). Equally, thinning or partial cutting of stands can be beneficial, as it requires use of smaller machines due to limited room to maneuver in the remaining forest, creating less disturbance and encouraging lichen growth on the remaining trees (Korosuo, 2014; Stevenson, 1986; Waterhouse et al, 2011).…”

“…other beneficial methods such as winter felling or alternative scarification methods have been mentioned earlier (Coxson & Marsh, 2001;Roturier et al, 2011). There is then potential to reconcile some of these differences in ways that benefit reindeer and incur little cost to the forestry industry (Bostedt et al, 2003;Sandström et al, 2006).…”
