Experience from other countries shows that major gains in forest productivity can result from incremental or intensive silviculture combined with improvements to tree species.
Current activities, such as navigation channel dredging, hydroelectric power production, agriculture, and silviculture , will not be stopped by the listing of the sturgeon.
Central to their beliefs was the idea that small farmers and trees did not mix, that agriculture and silviculture did not mix.
Five sites each occurred within forested landscapes disturbed by agriculture and those disturbed by silviculture .
Although adjacent to dense forests altered by silviculture , vegetation in the swale resembles that of boggy pine savannas or flatwoods.
Wells then offers a series of journalistic ‘field trips’ that recount interviews and tours of the forest taken with the forest manager, a silviculturist , an environmental activist, and the forest's recreation planner.
Most silviculturists plant 1000 seedlings per hectare at $1.25 per seedling for a cost of $1250.
Generally, these silvicultural openings are less than 2 hectares in size.
The solution was to separate agrarian and silvicultural production.
Scale is key to the success, says a San Juan district silviculturist .
