  1. Use vegetation removal together with mechanical disturbance to the soil

    A replicated, randomized, controlled study in 2004-2008 in Mediterranean Aleppo pine Pinus halepensis woodland in France (1) found that mechanical cutting of ground vegetation along with mechanical soil disturbance (scarification) increased Aleppo pine seedling density. Density (seedlings/m2) in plots with vegetation debris was higher in plots with one (2.8) or double scarification (1.2) than control plots (<0.1). Density in plots with no vegetation debris was highest in double scarification plots (2.8) and higher in one scarification (1.0) than control plots (0.1). Data were collected in January 2008 in 24 plots (14×14 m). There were four replicates of control, one scarification (vegetation cut, litter layer and top soil mechanically scratched in one direction) and double scarification (litter layer and top soil mechanically scratched in two directions) debris plots (vegetation debris scattered in the plot), and 12 plots with the same treatments but with vegetation debris removed. All plots were thinned in 2004 (from 410 to 210 trees/ha). Treatments were applied in 2005.

     

  2. Use prescribed fire: effects on young trees

    A replicated, randomized, controlled study in 2004-2008 in Mediterranean Aleppo pine Pinus halepensis woodland in France (Prévosto & Ripert 2008) found that prescribed burning increased Aleppo pine seedling density where woody debris was left but not where it was removed. Density of seedlings in plots with woody debris was higher when burned (2.1 seedlings/m2) than unburned plots (<0.1). Where woody debris had been removed, density was similar between treatments (unburned: 0.1; burned: 0.4). Data were collected in January 2008 in 16 plots (14 × 14 m): eight control plots with no fire and eight that had a prescribed fire in 2005. Four control and four burn plots had woody debris and four of each treatment plots had the woody debris manually removed. All plots were thinned in 2004 (from 410 to 210 trees/ha).
