Figure 15. Field sampling of land types in Khe Tran (total sample size 11 plots)<br />
village area was prone to flooding, this area was affected as well. Plantations have<br />
also experienced <strong>for</strong>est fires, especially in 1983.<br />
Most of the secondary <strong>for</strong>ests of the area have experienced disturbance rather<br />
recently. One plot (Plot 3) was established in <strong>for</strong>est that had experienced many<br />
fires in the period between 1980 and 1995, and in 1983 a big storm had caused<br />
many trees to fall. Earlier this area had also been used <strong>for</strong> shifting cultivation,<br />
and the <strong>for</strong>est was evaluated to be young, not more than 10 years old. The second<br />
secondary <strong>for</strong>est plot (Plot 9) was in older <strong>for</strong>est (40 years old) with clearly less<br />
disturbance, although it bore some marks of illegal logging. A third plot (Plot 11)<br />
was established at a site that had seen some fires in 1983, but the age of the <strong>for</strong>est<br />
was relatively high (40 years) and it was mainly used as a source of firewood and<br />
scrap metal.<br />
Two plots were established in gardens with more than 10 years of cultivation<br />
history after having been natural <strong>for</strong>ests—one a pepper garden and the other a<br />
jackfruit garden with riparian bamboo patches. Both areas had flooded in 1983<br />
and the riparian area had burned. The jackfruit garden had been a small bamboo<br />
plantation from 1986 to 1995, and be<strong>for</strong>e that it was a mixed banana, pineapple and<br />
cassava garden. Cassava and pineapple were still cultivated next to the jackfruit<br />
garden, which was presently not intensively managed and thus in close to natural<br />
condition with the main trees being jackfruits. In the pepper garden there had been<br />
cassava and sweet potato cultivation between 1996 and 2002 and natural <strong>for</strong>est<br />
be<strong>for</strong>e that. The rice field was a young fallow between the first harvests at the time<br />
of the survey. This area has also been cultivated with peanuts.
