Australian tree species selection in China AgEcon
McKenney, Daniel W..
The Australian Centre for International Agricultural Research (ACIAR), through collaborative projects with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the Chinese Academy of Forestry (CAF), has been involved in tree species selection trials in southern China since 1984. The trials were aimed at identifying fast-growing species of Eucalyptus, Acacia and Casuarina. The Chinese have been planting Australian tree species for more than 100 years, but before the ACIAR project there had been little progress in determining which species and provenances would be best for the local climate and soils. This paper presents an assessment of the economic impact of research undertaken under two ACIAR-supported projects....

Reptiles in Monterey pine plantations of the Coastal Range of Central Chile RChHN
Uribe,Sandra V; Estades,Cristián F.
BACKGROUND: In Chile, most of the timber industry depends on Monterey pine (Pinus radíala (D. Don.)) plantations, which now cover more than 1.5 million ha. In spite of the intensive management of these plantations, they are home to a large number of wildlife species. One of the least known groups in this type of environment are reptiles. For this reason, we conducted a study on the distribution and abundance of reptiles at plantations of different ages in seven sites in the Coastal Range of Central Chile. RESULTS: From seven species that could be potentially found in the study region, a total of five species were recorded, with Liolaemus lemniscatus (Gravenhorst) being the most abundant (with up to 160 ind*ha-1). Detectability of species was similar in...

Growth and survival over ten years of Brazil-nut trees planted in three anthropogenic habitats in northern Amazonia Acta Amazonica
SCOLES,Ricardo; GRIBEL,Rogério.
ABSTRACT We examined the growth and survival of Brazil-nut trees, Bertholletia excelsa (Lecythidaceae) under different environmental conditions and levels of canopy openness within experimental plantations in the Trombetas River valley, in northern Brazil. We planted 144 seedlings in three anthropogenic habitats with different levels of sunlight exposition: crop field (100% canopy opening), shrub fallow (20-80% canopy opening) and Brazil-nut forest (< 10% canopy opening). We measured plant height and diameter annually and recorded mortality and resprouting over ten years. The performance of B. excelsa differed significantly among habitats, with the highest growth rate observed at the highest level of canopy openness (crop field). Survival was highest in...

Establishing Acacia salicina under dry Mediterranean conditions: The effects of nursery fertilization and tree shelters on a mid-term experiment with saline irrigation Ciencia e Investigación Agraria
Oliet,Juan A; Planelles,Rosa; Artero,Francisco; Domingo-Santos,Juan M.
The restoration of dry lands in the Mediterranean is a challenging task because harsh abiotic conditions hamper the counteraction of feed-back degradation processes. Active restoration through planting must be performed to deter this process. In this study, we tested the influence of mineral nutrition in the nursery (two formulations of controlled release fertilizer at two rates each) and tree protection after planting (by using tube shelters) on the nine-year performance of Acacia salicina irrigated with low-quality (saline) water. The overall survival at the end of the study period was 58.2%, with the electrical conductivity of the soil saturation extract reaching 5.4 dSm-1 after nine years. The survival and growth (in height) were greater for seedlings...
