Fence to prevent grazing after tree planting

A replicated, controlled study in 2001-2002 in eucalypt forest in Australia (Parsons et al. 2006) found that kangaroo exclusion increased planted seedlings biomass and survival rate. Seedling biomass (excluded 41; control: 27 g dry mass/plot) and survival (excluded: 13/18 plants; control: 10/18 plants) were higher in exclusion plots. Data were collected in winter 2002 in 16 replicates (each planted with a different species) of four exclusion (2.1 m fence in May-June 2001) and four control plots (1.3 × 1.3 m). Each plot was planted with nine plants in August 2001, at each of two rehabilitated bauxite-mine sites.
Use different planting or seeding methods

A replicated, controlled study in 2001-2002 in eucalypt forest in Australia (Parsons et al. 2006) found no effect of planting density on planted seedlings biomass and survival rate. Seedling weight (low density 34.2; high density: 34.5 g dry mass/plot) and survival (leaving plant/18 plants) (low density 11.3; high density: 11.4) were similar between treatments. Data were collected in winter 2002 in 16 replicates (each planted with a different species) of eight plots: four planted at low-density (with nine plants) and four at high-density (0.5 and 0.1 m between plants respectively) in August 2001, at each of two rehabilitated bauxite-mine sites.
