“…As well as the difference in slope of the terrain is a plausible cause, the local topographic variation among forest types in this altitudinal gradient (see Alves et al, 2010) might be a factor controlling light availability and ultimately, tree height. Montane and submontane forest are located in steeper terrains when compared to the other forest types, so that the vertical distribution of light is expected to be more asymmetric than in flat areas .…”

“…These soils have in common a high sand content, with low pH, low phosphorus concentration, low sum of bases and high aluminum saturation. The density of trees, palms and tree ferns with DBH ≥ 4.8 cm ranged from 1467 up to 1885 stems ha -1 (average of 1,626 stems ha -1 ) in the restinga forest, 1,170 up to 1,298 stems ha -1 (average of 1,230 stems ha -1 ) in the lowland forest, 1,517 up to 1,926 stems ha -1 (average of 1,727 stems ha -1 ) in the submontane forest and 1,454 up to 1,834 stems ha -1 (average of 1,723 stems ha -1 ) in the montane forest Alves et al (2010) andSousa Neto et al (2010). Hereafter we will refer to these forest types by the altitudes of occurrence.…”

“…Using the database generated by Alves et al (2010), we randomly selected 268 trees stratified by altitude of occurrence and by DBH class to perform tree height measurements. The DBH classes were: < 10 cm, 10-30 cm, 30-50 cm and ≥ 50 cm.…”

Site-specific height-diameter models may be used to improve biomass estimates for forest inventories where only diameter at breast height (DBH) measurements are available. In this study, we fit height-diameter models for vegetation types of a tropical Atlantic forest using field measurements of height across plots along an altitudinal gradient. To fit height-diameter models, we sampled trees by DBH class and measured tree height within 13 one-hectare permanent plots established at four altitude classes. To select the best model we tested the performance of 11 height-diameter models using the Akaike Information Criterion (AIC). The Weibull and ChapmanRichards height-diameter models performed better than other models, and regional site-specific models performed better than the general model. In addition, there is a slight variation of heightdiameter relationships across the altitudinal gradient and an extensive difference in the stature between the Atlantic and Amazon forests. The results showed the effect of altitude on tree height estimates and emphasize the need for altitude-specific models that produce more accurate results than a general model that encompasses all altitudes. To improve biomass estimation, the development of regional height-diameter models that estimate tree height using a subset of randomly sampled trees presents an approach to supplement surveys where only diameter has been measured.

“…In general, montane forests have higher density of individuals, lower diversity of species and families and, vascular and avascular epiphytic, compared with other tropical forests at lower altitudes (HAMILTON et al, 1995;LIEBERMAN et al, 1996). Alves et al (2010) found an increase of aboveground biomass along of altitudinal gradient in the Ombrophilous Dense Atlantic Forest, as well as litter accumulation and carbon and nitrogen stocks, both above and below ground . In the montane forests, the environmental conditions are imposed by higher altitude belts and theirs species could be more sensitive to current changes in the global climate, suggesting an evidence of biodiversity loss a near future TABARELLI, 2000).…”

ABSTRAT Projects involving floristic-phytosociological surveys are becoming increasingly frequent and is a very important tool to access the biodiversity, status of succession, biomass and carbon storage, guiding conservation and management strategies. These studies are particularly important in Atlantic Forest, which is considered a hotspot in terms of biodiversity, endemism and impacts. São Paulo State lost more than 80% of original forest and, nowadays, remains only isolated patches with a variety stage of succession and history of use. The aim of this study was to characterize the structure, composition and biomass of the woody plant community in a Montane Ombrophilous Dense Forest, Serra do Mar State Park. All trees with DBH ≥ 4.8 cm were sampled in 1 ha plot area, totaling 1,704 individuals belonging to 38 botanical families and 143 species. The highest species richness was found in the Myrtaceae and Lauraceae families, and the greatest value of abundance and Importance (IV) was observed in the Arecaceae and Euphorbiaceae. The Shannon index (H’) was 3.7 nats.ind.-1 and the Pielou’s evenness index (J) 0.7, characterizing a very diverse community with heterogeneous distribution of individuals by species. The aboveground biomass was 166.3 Mg.ha-1, similar to others studies in Atlantic forests. The forest composition, biomass and the history of land use indicate a middle secondary stage of regeneration, but evolving to a more mature condition.
