Background: The use of tree species’ functional traits is a promising approach in forest restoration. However, some traits may change during ontogeny. Questions: Does intraspecific variation in functional traits occur between sapling and adult stages? Do groups of species can be delimited based on functional traits regardless of their ontogenetic stage? Study sites and dates: Cloud forest restoration, Veracruz, Mexico, 2016. Methods: Saplings and adults of eight native tree species in different age plantations were measured for leaf area (LA), specific leaf area (SLA), stomatal density (SD), foliar nutrient content (C, N, P) and relative growth rate (RGR). Wood density (WD) was measured for adults. Data were analyzed using linear mixed models and principal component analysis (PCA). Results: Overall, SLA was higher in saplings than in adults. A few species showed intraspecific variation for LA (three species), SD (three) and foliar N content (one). Species with high WD (Quercus spp.) and intermediate WD (e.g. Liquidambar styraciflua) tended to have lower LA and SLA, and higher SD. Species with low WD (e.g. Heliocarpus donnellsmithii) had high SLA, RGR, and N content. PCA highlighted that saplings and adults of a same species were close to each other within the ordination space.  Conclusions: Intraspecific variation between saplings and adults was small for most traits (except SLA) in comparison to differences across species. Therefore species trait values (measured in individuals of any age) could be a useful tool to characterize groups of species during the forest restoration trajectory.

Background and Objectives: The stable stand structure of mixed plantations is the basis of giving full play to forest ecological function and benefit. However, the monocultural Eucalyptus plantations with large-scale and successive planting that caused ecological problems such as reduced species diversity and loss of soil nutrients have presented to be unstable and vulnerable, especially in typhoon-prone areas. The objective of this study was to evaluate the nonspatial structure difference and the stand stability of pure and mixed-Eucalyptus forests, to find out the best mixed pattern of Eucalyptus forests with the most stability in typhoon-prone areas. Materials and Methods: In this study, we randomly investigated eight plots of 30 m × 30 m in pure and mixed-Eucalyptus (Eucalyptus urophylla S. T. Blake × E. grandis W. Hill) plantations of different tree species (Neolamarckia cadamba (Roxb.) Bosser, Acacia mangium Willd., and Pinus elliottii var. Elliottii Engelm. × P. caribaea Morelet) on growth status, characterized and compared the distribution of nonspatial structure of the monoculture and mixtures, and evaluated the stand quality and stability from eight indexes of the nonspatial structure, including preservation rate, stand density, height, diameter, stem form, degree of stem inclination, tree-species composition, and age structure. Results: Eucalyptus surviving in the mixed plantation of Eucalyptus and A. mangium (EA) and in the mixed plantation of Eucalyptus and P. elliottii × P. caribaea (EP) were 5.0% and 7.6% greater than those in pure Eucalyptus plantation (EE), respectively, while only the stand preservation rate of EA was greater (+2.9%) than that of the pure Eucalyptus plantation. The proportions of all mixtures in the height class greater than 7 m were fewer than that of EE. The proportions of EA and mixed plantation of Eucalyptus and N. cadamba (EN) in the diameter class greater than 7 m were 10.6% and 7.8%, respectively, more than that of EE. EN had the highest ratio of branching visibly (41.0%), EA had the highest ratio of inclined stems (8.1%), and EP had the most straight and complete stem form (68.7%). The stand stability of the mixed plantation of Eucalyptus and A. mangium presented to be optimal, as its subordinate function value (0.76) and state value (ω = 0.61) of real stand were the largest. Conclusions: A. mangium is a superior tree species to mix with Eucalyptus for a more stable stand structure in the early growth stage to approach an evident and immense stability and resistance, which is of great significance for the forest restoration of Eucalyptus in response to extreme climate and forest management.
