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). Choosing the best planting spot is critical and more important than exact spacing (Landis et al. 2010), 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). The risk of seedling mortality is not constant, but varies with tree species, planting density, tree age, and site conditions (Gadow and Kotze 2014). The decision on planting layout and density should, however, be project specific with aim to promote survival and reforestation success.
