Use patch retention harvesting instead of clearcutting
A controlled before-and-after study in May-June 1999-2001 in bottomland hardwood forest in South Carolina, USA (Harrison & Kilgo 2004), found that a small increase in species richness in the short-term in an area with patch-retention harvesting and a control area, whilst richness decreased in an area with clearcutting (patch retention area: 21 species in 1999, 15 in 2000, 25 in 2001; clear cut area: 25, nine, five; control area: 18 in 1999 and 30 in 2001). Species lost from the clearcut plot were mostly forest specialists. Estimated bird density in the patch-retention area fell from c.3.5 pairs/ha in 1999 to 17 in 2000, recovering to around 34 in 2001. In the clear-cut area, it fell from 3.3 pairs/ha before harvest to around three in 2000 and 14 in 2001. Densities in the control remained relatively constant (c.3.2 pairs/ha). Estimated bird density in the patch-retention area fell from 3.5 pairs/ha in 1999 to 1.7 in 2000, recovering to around 3.4 in 2001. In the clear-cut area, it fell from 3.3 pairs/ha before harvest to around 0.3 in 2000 and 1.4 in 2001. Densities in the control remained relatively constant (3.2 pairs/ha).
