  1. Remove woody debris after timber harvest

    A controlled study in 2007-2009 in Piñon-juniper woodland in Utah, USA (Ross, Castle & Barger 2012) found that shredding woody debris (mulching) increased understory vegetation cover. Cover of understory plants was higher in mulched (66%) than control plots (4%). Two treatment sites (0.4-0.9 km2) were established in 2007: mulching (using a tractor with an attached brush-cutter) and control (untreated). Data were collected in 2009 along ten transects (35 m) in each site.

     

  2. Thin trees within forests: effects on understory plants

    A controlled study in 2007-2009 in Piñon-juniper woodland in Utah, USA (Ross, Castle & Barger 2012) found that thinning increased understory vegetation cover. Cover of understory plants was higher in the two thinning treatments (piled and burned: 16%; woody debris: 21%) than control plots (4%). Three treatment sites (0.4-1 km2): piled and burned (trees manually cut with debris placed in discrete piles that were later burned), woody debris (trees manually removed and debris scattered across the site) and control (untreated) were established in 2007. Data were collected in 2009 along 10 transects (35 m) in each site.
