Thin trees within forests: effects on young trees Forest Conservation

A replicated, controlled study in 2000-2005 in temperate broadleaf forest in Ohio, USA (Lombardo & McCarthy 2008) found no effect of thinning on numbers of black oak Quercus velutina and chestnut oak Q. prinus acorns. The density (acorns/ha) of black oak (20,000-30,000) and chestnut oak (30,000-40,000) was similar between treatments. Data were collected in 2005 in nine thinned (thinning from below retaining 70% of tree basal area in 2000-2001) and nine unthinned plots (0.1 ha) at each of two sites.

 

Use prescribed fire: effects on young trees Forest Conservation

A replicated, controlled study in 2000-2005 in temperate broadleaf forest in Ohio, USA (Lombardo & McCarthy 2008) found no effect of prescribed fire on the number of chestnut oak Quercus prinus and black oak Quercus velutina acorns. Density was similar between treatments for both chestnut oak (burned: 300,000-350,000; unburned: 250,000-300,000 acorns/ha) and black oak (100,000-400,000 in both). Data were collected in 2005 in nine burned (prescribed fire in 2001 and 2005) and nine unburned plots (0.1 ha) in at each of two forest sites (40 ha).
