Thin trees within forests: effects on young trees
A replicated, randomized, controlled study in 2000-2005 in temperate forest in California, USA (Moghaddas, York & Stephens 2008) found no effect of thinning followed by mulching on conifer or California black oak Quercus kelloggii seedling densities. The combined density (trees/m2) of conifer and oak seedlings (thinned: 2.8; unthinned: 1.5) and the density of oaks (thinned: 0.40; unthinned: 0.45) were similar between treatments. Data were collected in 2006 in 10 sets of four plots (1 m2) in each of three thinned (trees >25 cm DBH removed in 2001, followed by mulching of the remaining trees) and three unthinned treatment units (14-29 ha).

Use prescribed fire: effects on young trees
A replicated, randomized, controlled study in 2000-2005 in temperate forest in California, USA (Moghaddas, York & Stephens 2008) found that prescribed fire increased conifer seedling and decreased oak seedling densities. Combined conifer and California black oak Quercus kelloggii seedling density was higher in burned (14.0/m2) than unburned plots (1.5/m2) while density of California black oak was higher in unburned plots (burned: 0.10; unburned: 0.45/m2). Data were collected in 2006 in 10 sets of four plots (1 m2) in each of three unburned control and three burned (October-November 2002) treatment units (14-29 ha).
