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.

To keep your asparagus bed productive, don't be greedy. The first year after planting, you can harvest a few spears from each plant. Pick for about two weeks and then stop so the fronds can unfold and begin feeding the root system. Harvest for three weeks the next year, and four to six weeks after that.Pick too much, and your plants will not be able to develop the strong root system and energy reserves they'll need to produce an abundant crop of spears the following season.
