A replicated, randomized, controlled, before-and-after study in 2004-2005 in subtropical forest in Brazil (Sampaio, Holl & Scariot 2007) found that sowing tree seeds increased the density and species richness of new trees. The increase in stem density (seeded: 2,000/ha; unseeded: 1,000) and number of species/plot (seeded: 3; unseeded: 0) was higher in seeded plots. Data were collected immediately before (January 2004) and one year after treatment (March 2005) in four replicates of adjacent unseeded control and seeded (ten tree species) plots (10 × 10 m).
