Selective logging, the targeted harvesting of timber trees in a single cutting cycle, is globally rising in extent and intensity. Short-term impacts of selective logging on tropical forests have been widely investigated, but long-term effects on temporal dynamics of forest structure and composition are largely unknown.n accord with the first prediction (Fig. 1), plots in the logged category had a higher intercept for stem turnover rate than plots in the unlogged category (Î²Ì1 Table 1), indicating that stem turnover rate was higher in logged than unlogged forest 31 years after the selective logging event (Fig. 3 A).

1 Asparagus is planted in early spring as soon as the soil can be worked. 2  The plant is grown from âcrownsâ (1-year-old plants). 3  Eliminate all weeds from the bed, digging it over and working in a 2- to 4-inch layer of compost, manure or soil mix.4  Dig trenches of about 6 inches wide and 6 to 12 inches deep.ou can transplant asparagus crowns when they are dormant and the ground is workable. Fall is a good time; early spring is also a possibility. Be careful when digging so as not to damage the rootsâdig about 8 to 12 inches out from the outer edge of a clump of dead foliage, in a wide circle.
