A site comparison study in 1978-1984 in dry tropical forest in Brazil (De-Souza Gomes Guarino & Scariot 2012) found that logging increased the survival of newly planted local tree seedlings. Tree seedling survival was the higher in heavily (64%) than in intermediately logged plots (50%), and the lowest in unlogged plots (41%). Forty seedlings of each of three tree species: Amburana cearensis, Cedrela ﬁssilis, and Sterculia striata were planted in each of three forest fragments (115-212 ha): heavily logged (in 1997), intermediately logged (in 1996) and unlogged. Mortality was determined one year after planting. Seeds were collected at the study site between June and July and were grown in a greenhouse until planted back in December 2002.
