Planting Layout and Density
Irregular planting pattern can complicate silviculture operations, but it can promote seedling survival and provide a close surrogate to successful natural regeneration that provides a more natural appearance of a landscape (Ivetić and Devetaković 2016[1]). Choosing the best planting spot is critical and more important than exact spacing (Landis et al. 2010[2]), because initial seedling performance is related to microsite performance. On sites with harsh conditions, planting in groups on deeper soil is recommended, regardless of adopted regular planting pattern (Stilinović 1991[3]). The risk of seedling mortality is not constant, but varies with tree species, planting density, tree age, and site conditions (Gadow and Kotze 2014[4]). The decision on planting layout and density should, however, be project specific with aim to promote survival and reforestation success.
