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.

When planting asparagus, it is possible to grow it from seed but it will take three years before you can have your first meal...and that would be taking patience to extreme levels-so it makes more sense growing asparagus plants from established crowns and reduce the waiting period to two years.pace the crowns about 40cm(16) apart in the trenches on 5cm(2) high mounds of rotted compost or manure. These mounds are created only below each asparagus crown and the roots fanned out across them.
