A decision regarding the boundary of this study was made to study the transport of all materials harvested in Ravalli County to wherever they were processed.
The geographic boundary of this study encompassed 510 contiguous census tracts covering 89% of the total land area in Dallas County.
As discussed previously other energy sources like fuel for transportation are not considered within the boundaries of this study.
In addition, the boundaries of this study (trees of southern Africa) moderated the size of the families and orders.
Since the children in our study showed valgus angulation, the reversal of knee angles from physiological varus to valgus occurs before two years of age and therefore outside the boundaries of this study.
Further research will have to show whether this is specific to the boundary conditions of this study or a general phenomenon.
The fourth boundary of this case study was the post-implementation phase.
Therefore, we defined α has ±60° angle offset for a main direction boundary of a UE in this study; the moving path within the range of 120° angle (±α degree based on P1P2) totally is determined as the same direction of P1P2.
However, the invincible use of post code boundaries in our study did not always reflect the actual neighbourhood boundary, which may be a limitation of this study if adjacent neighbourhoods were contrasting [ 30, 31].
Previous applications of the KDI measured disturbance to urban areas as delineated by geo-political boundaries while this study used a physical boundary of a small karst catchment.
It measured the percentage of tree mortality within a 15-mile radius around the census designated place boundary of each study community.
