9.4 Site level restoration strategies
9.4.1 Restoration of degraded primary forest
Degraded primary forest in Dagan demonstration area was formed from repeated
use of primary forest, mainly at the peak of hills in the southern and southeastern
areas. Analysis of characteristics showed that Degraded primary forests
still retain the main characteristics of the original forest, such as species composition,
soil structure and stand structure, capacity of natural reg<strong>en</strong>eration,
and an important function of ecological protection, so a basic managem<strong>en</strong>t
principle of forest restoration is to remove the causes for further disturbance
and degradation, and promote restoration through natural succession.
It is the key to id<strong>en</strong>tify the forest stands or sites to be protected, which
should have seed, wildlings or seed sources in neighborhood to <strong>en</strong>sure the
success of natural restoration. The community of degraded primary forest had
a stratified unev<strong>en</strong> -age structure, composed by arbor storey, shrub storey and
grass storey, and the canopy d<strong>en</strong>sity was is 1. O. There are many valuable n­
ative trees with better stem form such as Dalbergia odorifera, Hopea exalata,
Vatica mangachapoi and Litchi chin<strong>en</strong>sis in arbor storey. Shrub storey and
grass storey in forest stands have rich species and valuable tree saplings and
