“…Our study showed that the SWV of dipterocarp species was similar (p > 0.05). Our result was consistent with other studies reporting no correlation between different species with SWV (Ishiguri et al 2007;2011;Makino et al 2012;Karlinasari et al 2018). The SWV of heavy-hardwood dipterocarp species (e.g.…”

“…The forest production of lowland dipterocarp forests is managed through selective cutting (Appanah 1998;Dawkins and Philip 1998;MOF 2009;Putz et al 2012). The cutting cycle is 25-30 years (MOF 2009), and it generally allows the cutting of all commercial tree species with a minimum diameter breast height (DBH) of >50 cm (MOF 2009;Finkeldey 2011). However, selective cutting can damage more than 50% of trees in the stand and affect the structure, species composition, and production of a logged-over area (Pinard and Putz 1996;Huth and Ditzer 2001;Kartawinata et al 2001;Sist et al 2003).…”

The selection of species for enrichment planting that involves native species in a secondary lowland dipterocarps forest as one of the tropical rainforest types should be conducted to maintain the sustainable management of tropical rainforests. The research of species trial of dipterocarp species was planted under a randomized complete block design with four replications. The following parameters were examined: survival rate, diameter breast height (DBH), pilodyn penetration (PP), and stress wave velocity (SWV). The survival rate (F ¼ 1.72; p ¼ 0.047), DBH (F ¼ 6.67, p < 0.0001), and pilodyn penetration (F ¼ 14.19; p < 0.001) significantly differed at 12.5 years after planting. The survival rate of Shorea leprosula was the highest (85%) of all the species, and the survival rate of other species, namely, S. macrophylla, S. ovalis, S. johorensis, S. scaberima, and S. parvifolia, was more than 70%. The best growth of DBH parameter was observed in S. platyclados. The DBH growth of S. platyclados 12.5 years after planting were 27.62 cm (mean annual diameter increment [MADI] ¼ 2.2 cm/year). The species whose growth in DBH was similar to those of S. platyclados were S. leprosula, S. parvivolia, and S. ovalis. However, stress wave velocity (SWV) was not significantly different among dipterocarp species (F ¼ 1.26; p ¼ 0.234). Pilodyn penetration (PP) was significantly correlated with DBH (Pearson's correlations ¼ 0.306; p < 0.001), whereas stress wave velocity was not significantly correlated with DBH and PP (p > 0.05), and their Pearson's correlations were 0.043 and À0.012, respectively. These results suggested that each dipterocarp species varied in terms of their growth and wood properties. Thus, choosing the species for enrichment planting in secondary tropical rainforests depends on the characteristics of each species and the desired final product of forest management.

“…However, even though valuable natives have different constraints that limit their use in plantations, there is a growing interest in Guatemala to increase their use, several of the landowners of sites visited during this research, are eager to continue testing different schemes for their cultivation. A critical issue that arises is the need for exploration and assessment for ex-situ conservation of diversified and phenotypically desirable materials for these species, as a key component for their long-term conservation and utilization, as suggested by different authors (Finkeldey, 2011;Finkeldey & Hattemer, 2007).…”

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.
