“…This can be a source of error that needs to be considered. On the other hand, the strong, linear relationship between the DBH and H of MB agrees with the results by previous studies for other tree species, which indicate that DBH is also used as a reliable crown trait for H estimations [11,55,88,89], and using both DBH and H as independent variables to estimate LA cannot significantly improve, or even reduce, the accuracy of estimations [13,90,91]. Therefore, DBH is a better predictive variable for the allometry of LA of MB crowns.…”

Both leaf area (LA) and leaf angle distribution are the most important eco-physiological measures of tree crowns. However, there are limited published investigations on the two parameters of Moso bamboo (Phyllostachys edulis (Carrière) J. Houz., abbreviated as MB). The aim of this study was to develop allometric equations for predicting crown LA of MB by taking the diameter at breast height (DBH) and tree height (H) as predictors and to investigate the leaf angle distribution of a MB crown based on direct leaf angle measurements. Data were destructively sampled from 29 MB crowns including DBH, H, biomass and the area of sampled leaves, biomass of total crown leaves, and leaf angles. The results indicate that (1) the specific leaf area (SLA) of a MB crown decreases from the bottom to the top; (2) the vertical LA distribution of MB crowns follow a “Muffin top” shape; (3) the LA of MB crowns show large variations, from 7.42 to 74.38 m2; (4) both DBH and H are good predictors in allometry-based LA estimations for a MB crown; (5) linear, exponential, and logarithmic regressions show similar capabilities for the LA estimations; (6) leaf angle distributions from the top to the bottom of a MB crown can be considered as invariant; and (7) the leaf angle distribution of a MB crown is close to the planophile case. The results provide an important tool to estimate the LA of MB on the standing scale based on DBH or H measurements, provide useful prior knowledge for extracting leaf area indexes of MB canopies from remote sensing-based observations, and, therefore, will potentially serve as a crucial reference for calculating carbon balances and other ecological studies of MB forests.

“…The Nf can be easily measured in some palm species, and has been often used for estimating their biomass component and leaf area as a part of combined predictor of D 2 HNf [11,16]. Although CD was also a direct measure of foliage size as well as Nf, the CD showed the worst fitting for the variables examined alone.…”

“…This is due to a lack of allometric equations specific to palms (e.g., [9,10]). Few studies focus on palm above-ground biomass [9,[11][12][13] and there is only a single study for below-ground biomass estimation [12]. The palm species shows unique plant architecture and anatomical characteristics.…”

Allometric models to estimate biomass components such as stem mass Ms, foliage mass Ml, root mass Mr and aboveground mass Ma, were developed for the palm species Euterpe precatoria Mart., which is the most abundant tree species in the Amazon. We harvested twenty palms including above-and below-ground parts in an old growth Amazonian forest in Brazil. The diameter at breast height D ranged from 3.9-12.7 cm, and the stem height H ranged from 2.3-16.4 m. The D, diameter at ground basis D0, crown diameter CD, H, stem specific gravity ρ, and number of fronds Nf were considered as independent variables and incorporated into a power function model. 451 stem tissue. The average root/shoot ratio was estimated as 0.29 which was higher than that reported for the non-palm tree species in the Amazon. Comparisons of several models to estimate Ma of different palm species, suggested that the variations of the D-H relationship and ρ should be considered to develop allometric models for estimating biomass in palm species. In particular the ρ largely varied depending on individual size, which should be important to consider, when developing the allometric models for palms.

“…(2013), developed for palm species in the Amazon, was used in this study for estimating the biomass of palm species: where D is the DBH (cm) and a and b are the model parameters to be estimated. This equation has also shown high levels of certainty when used in individuals of the Areaceae family (Avalos & Sylvester, 2010; Goodman et al., 2013). Because no studies reporting the wood density for the tree species sampled in Belize was found, we used wood density values reported of studies in Central America (Chudnoff, 1984; Reyes et al., 1992; Zhu & Waller, 2003) and south of Mexico (Urias, 1996).…”

A challenge in community ecology is the development of ecosystem baselines, allowing the assessment of the variation in the ecological dynamics through different temporal and spatial scales. To our best knowledge, no studies have been carried out in seasonal evergreen forests of Belize to establish a baseline for future monitoring. Hence, a floristic study of the woody plant species diversity and composition was carried out at the Billy Barquedier National Park (BBNP) to develop an ecosystemic baseline for the assessment of the originally implemented conservation strategies. A thorough floristic survey was performed from May to August 2015 in 42 rectangular plots (500 m 2) randomly allocated along the 100 to 500 m elevation gradient of the BBNP. Species richness, diversity, composition, and aboveground biomass were assessed. Likewise, information of a series of indicators on protection and risk situation (e.g., IUCN Red List of threatened species, CITES categories), and restoration for each relevant species are also provided. The BBNP is an important forest with 67 woody species distributed in 30 plant families. Terminalia amazona and Corozo palm Attalea cohune are the most important species in the reserve, in terms of abundance, frequency, and biomass. A clear trend between biodiversity metrics, elevation, and aboveground biomass was noted. This study contributes to understand relevant ecological topics as well as provides key elements for the management and conservation of the BBNP area and Belize.
