  • Supplying Sawmills with Native Species from Ecological Restoration in Southeastern Brazil: Analysis of Potential Original Article

    Abstract in English:

    Abstract The objective of this work was to evaluate the potential of native species used in ecological restoration in Brazil (Peltophorum dubium - canafístula, Hymenaea courbaril - jatobá, Jacaranda cuspidifolia - jacarandá, and Enterolobium contortisiliquum - timboril) as raw material for the supply of sawmills. Due to the difficulties in sampling trees of native species, four trees per species were collected, at age of 12 years, in a legal reserve area. The sampled trees were evaluated as being quite characteristic of trees of the same genetic material. The trees’ diameter was measured, the percentage of bark and the taper were measured, and the lumber yield of each species was calculated. The boards were air-dried. Based on the DBH, timboril had the greatest potential for biomass production, but its wood quality was unsatisfactory. To supply raw material for sawmills, in addition to jatobá, we suggest investing in plantations of canafístula and jacarandá.
  • Comparing Reliability of FHM and ISA Methods in Assessing Old and Large Dipterocarp Trees Health Original Article – Conservation Of Nature

    Abstract in English:

    Abstract Forest Health Monitoring (FHM) and International Society of Arboriculture (ISA) methods are used for individual tree health assessment. However, comparing the reliability of both methods in assessing large and old tree health has yet to be evaluated. This study aims to determine reliability of two methods in evaluating the health condition of old (>100 years old) and large Dipterocarp trees in Bogor Botanic Garden (BBG), Indonesia. The parameters observed were growth, morphometry, and tree health of 44 trees. The results showed that, overall, the two methods demonstrated quite similar in assessing the health condition of targeted trees. Visual tree damage domination by conks, fruiting bodies, and other indicators of advanced decay, open wounds, and termite gallery. The average risk rating of three parts of the tree (branches/crown, trunk, roots) is low to moderate. The two approaches could be used simultaneously or separately according to the purpose of the assessment.
