“…In the past two decades, new restoration approaches in the tropics have emphasized the establishment of highly functional plantation forests with native species in mixed stands. Recent studies suggest positive mixture effects on many ecosystem functions such as lower tree mortality, enhanced biomass productivity coupled with higher resource-use efficiency (including nutrients, water, and light) by trees, higher decomposition rates, reduced damage from pest or diseases, and better nutrient retention than the mono plantations (Forrester, Theiveyanathan, Collopy, & Marcar, 2010;Healy, Gotelli, & Potvin Partitioning, 2008;Hung, Herbohn, Lamb, & Nhan, 2011;Lawson & Michler, 2014;le Maire et al, 2013;Nichols, Bristow, & Vanclay, 2006;Puettmann & Tappeiner, 2014;Richards, Forrester, Bauhus, & Scherer-Lorenzen, 2010). Vietnam, China, and the Philippines encourage landholders to plant mixtures by their national reforestation programs (Lamb, Erskine, & Parrotta, 2005); in several countries, for smallholder and community forestry (mostly of native species) (Herbohn et al, 2014) there is often little comprehensive information.…”

In India, reforestation programs with native indigenous tree species are a recent activity. Information on experiences comparing mono-and mixed-species plantations is limited. This study aims to estimate growth, aboveground biomass, and carbon sequestration between the mixed-species plantation and mono-species plantation. The growth, survival, height, aboveground biomass, and carbon sequestration of 82 native mixed species plantations were compared with Casuarina equisetifolia an exotic species planted in this region after over a decade (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016). In the mixed species plantation, 7 species showed 100% survival rate and 19 species were not survived after over a decade intervals. While in the mono plantation, C. equisetifolia showed 92% of the survival rate. The growth rate of mixed species when compared to mono plantation, it showed highly significant differences (P < 0:05) values. Simple linear regression between annual girth increment and height produced very strong positive relations (R 2 0.759). The aboveground biomass estimated for the mixed native plantation was 8.007 tonnes and the mono plantation Casuarina had 5.585 tonnes. The total carbon stock estimated for the tree plantation in the two plots (both mixed native and mono) was 7.492 tonnes. A positive correlation was observed between the carbon stock and density of the top 10 species which contributed predominantly to the total carbon stock (rs = 0.773, p < 0.05). Plantation of C. equisetifolia seems to be well adapted and had more carbon stocking potential. On the other hand, mixed plantation with indigenous species would contribute more to sustainable management and they provide great shelters for many faunal communities and provide a greater range of ecological goods and ecosystem services than the mono plantations.

“…Si son bien diseñadas, las plantaciones mixtas pueden diversificar la producción, reducir los riesgos fitosanitarios, facilitar algunas prácticas de cultivo (poda y control de malezas), mejorar el paisaje (Gabriel et al, 2005;Hung et al, 2011) y elevar la calidad de la madera al reducir tanto las bifurcaciones como la cantidad de ramas gruesas, que la degradan (Hung et al, 2011). La asociación con especies fijadoras de nitrógeno presenta mayores crecimientos en relación a plantaciones puras (Forrester et al, 2011;Hung et al, 2011).…”

El proceso de diversificación forestal en Chile ha estimulado el interés por cultivos y modelos productivos no tradicionales, dentro de los cuales las plantaciones mixtas han mostrado utilidad para la realidad forestal al favorecer el crecimiento en altura y diámetro. Debido a la ductilidad de su madera, el roble europeo (Quercus robur L.) es altamente demandado en el mercado internacional. Este estudio determinó el efecto en el crecimiento y la calidad fustal del Q. robur de varias asociaciones establecidas y manejadas mediante silvicultura con apego a la naturaleza en el fundo Miraflores (Lanco, Región de los Ríos, Chile), haciendo un muestreo de 200 árboles futuro por asociación (una pura y nueve mezclas diferentes). Los resultados indican que la proporción de árboles futuro es mayor en las asociaciones mixtas respecto a la pura; y que el crecimiento en altura y diámetro en la situación pura es mayor que en las mezclas analizadas. No obstante, lo anterior, no se recomienda la plantación pura, pues este manejo provoca una importante penetración de luz, que favorece el desarrollo de características que descalifican la calidad de madera, como la aparición de brotes epicórmicos. Se concluyó que las asociaciones más favorables para el desarrollo de Quercus robur incluyen arce (Acer pseudoplatanus) y castaño (Castanea sativa), seguida de pino oregón (Pseudotsuga mensiezii) y castaño.

“…Different topics of management with tropical valuable-timber native species have been identified, including the need for sophistication of reforestation treatments, including the comparisons of mixtures with monocultures, paying attention to potential complementary effects when combining species with different shade tolerance (Hung, Herbohn, Lamb, & Nhan, 2011), the need to advance in understanding the ecosystem services and functions (Forrester, 2014;Hall, Ashton, Garen, & Jose, 2011), the balance between production and conservation roles of plantations (Lamb et al, 2005;Pryde, Holland, Watson, Turton, & Nimmo, 2015), the potential advantages that can be gained when cultivating species in carefully designed mixtures instead of monocultures (Kelty, 2006), which can lead to increases in growth rates and economic gains if proper ecological combining ability among species can be achieved (Menalled, Kelty, & Ewel, 1998), adding as well other ecological benefits (Piotto, 2008).…”

The North Humid Guatemalan Lowlands contains a significant diversity of tree species, incluiding some valuable-timber producers; these species are threatened by commercial overexploitation and habitat loss due to deforestation. The cultivation of these species in forest and agroforest plantations is a potentially viable optiontheir conservation and commercial harvesting, something that has been promoted with Government Incetemala during the past two decades. However, these species have not been widely planted, among othebecause knowledge on their ecological requirements and silviculture is scarce. A characterization of momixed plantations with 14 native valuable-timber species was made in the Humid Lowlands of Northeranalyzing for each species frequency of association and accompanying species, planted area, the main etures and growth rates. To gather information, we combined field observation and measurements with iliterature review. Based on our survey, main management challenges for cultivation of the species were described. Valuable-timber native trees could potentially be sustainably cultivated in the study zone in diffforest plantations and agroforestry schemes of coffee, cacao, cardamom and cattle; considering their suitdiversified systems, growth performance and farmer’s preferences, Swietenia macrophylla, Cedrela odordonnell-smithii, Calophyllum brasiliense and Cordia alliodora were the species with the higher potentiain plantations. However, several unsolved problems continue restricting the cultivation of these species itherefore, is essential a careful design and management.
