In order to reduce hazards caused by flash, heat, blast, noise, ground shock and fragments, an isolated area with good road access is ideal.

Vegetation: Possible non-regeneration of high forest; Possible extinction or depletion of whole species; Genetic erosion as a result of selective cutting of superior trees; Undesirable secondary forest growth; Influx of persistent weeds; Possible mechanical damage and “isolation shock” killing seed trees; Possible damage to adjacent and cut forest by machinery, wind throw, fires, illegal felling, sedimentation, hydrologic changes and intensified shifting cultivation; Possible effects on regeneration by changes in the populations of animals that act as pollinators or seed vectors.
