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).
It will pay off later. Before planting you should soak your asparagus crowns in water for about an hour, especially if you mail-ordered them like I did. While they are soaking, you can prepare the bed.Be sure to select a spot where the four foot tall asparagus ferns are not going to shade other plants.t will pay off later.

Taking three weeks to germinate and slow to get going, the asparagus seeds should be sown indoors 12 to 14 weeks before the target seedling set-out date, which should be after the danger of frost has passed. Sow seeds 1/4-inch deep using a sterile seeding mix in individual 2-inch cells.
