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.

Sow the seeds for your aster plants as early in the season as possible, but make sure to plant after the last frost. Aster seeds normally germinate in about 10 to 14 days. Make sure not to cover the seeds with too much soil.tep 2: Prepare the Soil. Before sowing your aster flower seeds, you will need to prepare the soil. Add compost and animal manure to the soil and turn it. If you do not have animal manure available, purchase a quality super phosphate nutrient additive from your local nursery or home improvement store.
