| Characterization of land types The edge of old growth primary forest is not easily reached by walking from the Khe Tran village. Some of the oldest patches of forest lie close to the mountain tops or on steep slopes reached only after more than one hour’s climb and walk. The only plot in mature secondary forest closest to the condition of primary forest was established in 60-to-70-year-old stands visited regularly, but not often, by villagers. Men and women come to this site to collect rattan, honey and metal. The forest was afforded protected status by the provincial government in 1983, and the earlier regular hunting for bear, ‘helmeted’ hornbills, elephants and porcupines was thus forbidden along with timber production activities. Shrub lands (or bare hills) are a rather heterogeneous land type category with areas that have a history of having been under sugar cane cultivation (Plot 2) but are now fallows waiting to be converted to production area. Villagers describe those barren areas without any clear function for villagers as being degraded or barren because of the impact of chemicals during the war time (Plot 8). 7.2. Specimen collection and identification A total of 754 plant specimens were collected from 11 plots (Figure 16). In addition to systematic plot sampling of trees and non-trees, the most abundant seedling, sapling, shrub and monocot species were also recorded and sampled separately. In the text all the categories of ‘abundant’ species refer to this separate census, if not otherwise stated. Table 19 shows the division of specimens in trees, non-trees and abundant species. In total 108 families comprising 260 genera and 439 species were recorded (Annex 3 provides the botanical names, families and local name of specimens collected within and outside the plots). The number of unidentified taxa remains high due to the technical difficulties in sampling as well as the high vascular plant richness of the area. The sampling was not exhaustive, and was not supposed to be so, as one of the main objectives of using MLA was to test the relevance of such a tool in the Vietnamese context. Nevertheless the sampling using 11 plots in total was considered rigorous and adequate for non-tree representativeness, since the curves of cumulating numbers of non-tree vascular plant species laid against cumulating numbers of random subplots are levelling out for most land types (Figure 17). There was surprisingly diverse under storey in the plantation forests and thus they could have been sampled with an additional plot. For trees this short inventory time did not enable as good sampling as for non-trees, but nevertheless the collected data can be used as a basis for recommendations and considerations of further inventories of the forests. For trees the accumulation curves show in most of the land types no levelling down, pointing to the need for more plots, which were unfeasible considering the time constraints.
