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.

1 Once you can see the root and shoot, plant the seeds on their sides in the growing medium of your choice. 2  Make a small hole ready for them rather than forcing them in with your fingers. 3  Plant them about half an inch (1.25cm) deep, cover them gently with the growing medium and give them water, but not too much.any growers like to soak their seeds in plain tap water for 12 hours before planting. This is useful for two reasons: 1  Viable seeds tend to sink and non-viable seeds tend to float. 2  The pre-soaking softens the outer hull and makes germination easier.
