Ba Na Nature Reserve 1996 5.2 Results 5.2.1 Forest tree survey Transect diagrams for the five transects studied are shown in Appendix 2. A summary of the data collected in the five forest survey sites is given in Table 1, below.Table 2 shows the relative abundance and stocking densities of trees of different families. In addition to the families shown in Table 2, several families were represented by very few individuals in the transects studied. These families included Aquifoliaceae, Arecaceae, Dilleniaceae, Fabaceae, Myrsinaceae, Proteaceae, Sabiaceae, Samydaceae, Simaroubaceae, and Staphyllaceae. Table 1.
