Changes in the Ecological Parameters of Mixed Forests of Sal (Shorea robusta Gaertn.) Are a Function of Distance from the Human Settlements

Figure 4

Density (stems ha−1) of Shorea robusta (categorized as groups under saplings, poles, and trees) plotted against the distance from the village boundary lines. (a) Janajagaran BZCF, (b) Musharni Mai BZCF, (c) Radha Krishna BZCF, and (d) Parsa Wildlife Reserve. Solid lines in the figure indicate the density of the trees. Salmon colored dotted lines show the density of poles, and purple colored dotted lines show the density of saplings. The vertical lines are standard error bars. The horizontal lines are the reference density lines for the maximum number of mature trees (85 stems ha−1) that 1 ha plot can withstand.
