The objective of this study was to determine the effect of (i) pasture type, (ii) leucaena stand age
(0-40 years) and (iii) profile depth (0-1.0 m) on the amount (t [ha.sup.-1]) and origin ([C.sub.3]- or [C.sub.4]-C) of fLF-C using stable [sup.13]C isotopes.

In these ecosystems differences in stand age
are associated with variation in species-specific regeneration rates but little change in the suite of species present.
Generally, forest stand development has a strong relationship with carbon pools of forest ecosystem because tree growth rate of forest ecosystem mostly varies with stand age
Invasive shrub distribution varies with distance to roads and stand age
in eastern deciduous forests in Indiana, USA.
(2006) reported that microhabitat and stand age
of sand have effects on soil seed viability and seedling development.
Thirdly, it is difficult to estimate stand age
in forest inventories of large scale.
Two different stand age
groups were formed (5 to 7 years and 8 to 12 years), each with approximately the same number of sample plots, based on statistical tests that showed differences in key attributes, including density, diameter, and volume.

 focused on the ant population ratio in natural forests and oil palm plantations, but she had not yet discussed how changes in ant communities in line with the development of peat land with different palm stand age
. While Bruhl and Eltz,  studied the loss of forest ant species on oil palm plantations in Sabah, Malaysia.
The trajectory of a let-grow forest -- one that is not harvested but left to grow -- is based on the observed rate of live tree carbon by stand age
. It illustrates a slowing growth rate of net aboveground carbon sequestration as the forest ages.
