“…Both natural forests and mixed stands had better hydrological function than monospecific tree plantations (Liu et al 2003). Large amounts of nutrients were lost from fast-growing monoculture plantations through timber harvesting (Merino et al 2003(Merino et al , 2005. Proença et al (2010) reported that 28 plant species were observed in eucalypt plantation, while 52 and 33 were observed in oak forest and pine plantation, respectively.…”

Understory plant diversity assessment of Eucalyptus plantations over three vegetation types in Yunnan, China

et al. 2010

Biodiversity in managed plantations has become an important issue for longterm sustainability of ecosystems. The environmental effects of plantations comprised of fast-growing introduced trees have been vigorously debated. On one hand, monocultures have been said to exhaust resources, resulting in decreased biodiversity. Conversely, it has been stated that monocultures may favor regeneration of undergrowth plants from surrounding forests, increasing biodiversity. In order to clarify the effects of planting Eucalyptus trees on species composition, diversity, and functional type of understory vegetation in Yunnan province, a field trial was implemented to compare Eucalyptus plantations (EPs) with two other local current vegetation types (secondary evergreen forests (SEs), and abandoned farmlands (AFs)). Each vegetation type was sampled in each of three elevational ranges (low = 1,000-1,400 meters above sea level (masl), medium = 1,400-1,800 masl, and high = 1,800-2,200 masl). Sample sites within each elevational range had similar environmental characteristics (slope, aspect, etc.). Thus, we sampled three vegetation types at each of three sites at each of three elevations for a total of 27 plots. We calculated relative abundance and importance value of species and diversity indexes to evaluate differences among local current vegetation types and elevational ranges, employing multivariate ordination analyses and other methods such as Analyses of Variance (ANOVA) and Indicator Species Analysis. We found that fast growing introduced Eucalyptus plantations led to reduced plant diversity in the study area, and that rare or threatened species were recorded almost exclusively in the SE plots, being essentially absent from the EP and AF plots. The understory plant diversity did not correlate with the altitude gradient significantly. Eucalyptus plantations (EPs) have a simpler community structure than that of either secondary evergreen forests (SEs; similar to natural state) or abandoned farmlands (AFs). No variable significantly explained variation of the understory shrub layer, but soil moisture-holding capacity and overstory coverage were significant in explaining variation of the understory herb layer, suggesting that the study of soil physical properties is necessary for better understanding of their importance in Eucalyptus plantations and other local current vegetation types.

“…In additional studies carried out in commercial plantations, observed volume growth increases always higher than 38% relative to the unfertilized control two years after planting. The recommended doses at planting are summarized in Table 1, which also includes results reported by Merino et al [35] and Vega-Nieva et al [44] and the risk of fertilizer leaching in the rainier regions. Unsurprisingly, responses to mainly N and P were found in the soil with low organic matter content in SW Spain (Mediterranean climate, with rainfall between 450 and 950 mm year´1) [43].…”

“…The average nutrient concentrations in leaves of some Eucalyptus globulus plantations in Spain are shown in Table 2. Merino et al [35] found that foliar concentrations of N and micronutrients were satisfactory in all of the 44 E. globulus plantations aged 2-6 years assessed in northwest Spain. However, levels of P and Ca were low in most of the plantations, and levels of Mg and K were low in some plantations.…”

“…Although initial fertilization is considered necessary in Spain, a single dose is often only applied, and the effects may disappear within two years [35], well before canopy closure in temperate countries. In Brazil, forest plantations are repeatedly fertilized after establishment (although 100% of the phosphorus, which is rather immobile, can be applied in the first operation) until canopy closure (which occurs within one to two years, depending on the growth rate) [36].…”

Eucalyptus globulusLabill is the main exotic broadleaf species planted and managed for pulp and energy production in Spain, where it covers an area of more than 0.6 million ha. The climatic and soil conditions of the planting areas range from the predominantly acidic or fertile soils developed over limestone in Atlantic areas of the north and northwest of the Iberian Peninsula to the less weathered soils developed from slates, sandy deposits or limestone in the drier southwest. The widely varying conditions explain the large differences in proposed fertilizer prescriptions. This review paper provides an analysis of the proposed practices and prescriptions by considering trial results and the need to develop site specific prescriptions for seedling standards and fertilization at planting establishment. Analysis of nutritional studies and of nutrient balances over a whole rotation is presented in order to provide basic information for defining maintenance fertilization, identified as the main bottleneck for sustainable wood production in these stands. Different fertilization practices are used by non industrial owners and Spanish pulp companies, with the last one applying a more intense management relying in more fertilization. A complete consideration of nutrition-related operation and decisions is shown to be essential for maintaining potential productivity, reduce biotic and abiotic damages and reduce mineral fertilization needs.

“…In Spain, tree biomass equations for this species have been fitted in Galicia (Balboa-Murias et al, 2006), along with general models for the country as a whole (Montero et al, 2005). In addition, other studies have been conducted that relate biomass production of radiata pine with soil properties or nutrient accumulation (Rey et al, 2001;Merino et al, 2003). Recently, BalboaMurias et al (2006) carried out a study of the temporal variations and distribution of carbon storage in radiata pine and maritime pine pure stands under different silvicultural management.…”

Aim of the study: The aim of this study was to develop a model for above-ground biomass estimation for Pinus radiata D. Don in Asturias.Area of study: Asturias (NE of Spain). Material and methods: Different models were fitted for the different above-ground components and weighted regression was used to correct heteroscedasticity. Finally, all the models were refitted simultaneously by use of Nonlinear Seemingly Unrelated Regressions (NSUR) to ensure the additivity of biomass equations.Research highlights: A system of four biomass equations (wood, bark, crown and total biomass) was develop, such that the sum of the estimations of the three biomass components is equal to the estimate of total biomass. Total and stem biomass equations explained more than 92% of observed variability, while crown and bark biomass equations explained 77% and 89% respectively.
