TL;DR: Wang et al. as discussed by the authors provided a concise overview of eucalypt plantations management and the role and importance of the plantations for society, and explained the importance and impacts of modern plantations management practices.
Abstract: The key issues facing eucalypt plantations in China have been long standing. Firstly they were caused by the low level of socio-economic development. Also, eucalypt plantation management by many commercial growers is not scientifically based; their silvicultural management is not well attuned to characteristics of these species. Although interpretation and analyses of operational problems for eucalypt plantation were published in national newspapers, magazines, or delivered in the conferences and other occasions, criticisms, misunderstandings and rumors of eucalypts are still given undeserved and inappropriate attention in popular media. As a result, the development and management of eucalypt plantations nowadays attracts considerable controversy. This article provided a concise overview of eucalypt plantation management and the role and importance of eucalypt plantations for society. It also explained the importance and impacts of modern eucalypt plantation management practices. Based on analyses of key challenges and problems facing eucalypt plantations, especially in regards to land-clearing and land preparation, we offer constructive suggestions on solutions and insights to help people understand eucalypt plantations and management of this resource.
TL;DR: In this paper, a study was conducted on the growth and biomass of six-year-old Eucalyptus urophylla plantations in Leizhou Forestry Bureau, which indicated that the tree height and diameter increased with the increasing of tree ages, but the increasing tendency of height became slowly,diameter variation had no big difference.
Abstract: Eucalyptus is an important fast-growing tree for fiber and played vital role in forestry development.The study was conducted on the growth and biomass of six-year-old E.urophylla plantation in Leizhou Forestry Bureau.The results indicated that the tree height and diameter increased with the increasing of tree ages,but the increasing tendency of height became slowly,diameter variation had no big difference.It was feasible to use the study results with good effects by the least square method to estimate the biomass of Eucalyptus urophylla by groups.Biomass obviously increased with the age becoming old and leave biomass increased quickly in the initial stage.The biomass of stem-wood and bark accumulated speedly after three years.In six years old plantations,its biomass of stem-wood was more than half of total biomass,and over 58% of the above-ground biomass.All these results would be taken as an important technical guidance for the cultivation of short-period fiber of E.urophylla.
TL;DR: The results of variance and genetic analysis including 93 E.urophylla clones showed that there were high significant differences in growth and form quality characters among clones.
Abstract: The results of variance and genetic analysis including 93 E.urophylla clones showed that there were high significant differences in growth and form quality characters among clones. Individual tree volume of 45 clones were more than that of all clones means. All characters showed middle to strong genetic coherence. There were close positive correlations among growth characters except ratio of height to DBH. Stem form showed certain independence. The equation was established by using select index method of multi-characters. Meanwhile,18 clones were selected with the rate of 19.355% by using the criterion which was larger than the total selection index average plus a selectoin index standard deviation.
TL;DR: There were 64 undergrowth species in common between the secondary forest and Eucalyptus plantations, indicating that species structure was different between these two forest types.
Abstract: This study investigated the diversity of undergrowth plants growing under secondary broadleaf forest and under Eucalyptus plantations in southern China. Under secondary forest 123 undergrowth species were found and these represented 52 families whilst in Eucalyptus plantations 102 undergrowth species were found these represented 49 families. There were 64 undergrowth species in common between the secondary forest and Eucalyptus plantations, indicating that species structure was different between these two forest types. Measures of diversity for the understory species including richness index, evenness index and diversity index for secondary forest were slightly higher than those for Eucalyptus plantations. Analyses of variance revealed significant differences between the understory plants of these two habitats. There were only three species in common between the top 10 species ranked by Importance Value in each of the two habitats. Even so, the diversity of undergrowth plants of Eucalyptus plantations was similar to secondary forest.
TL;DR: Leptocybe invasa Fisher La Salle is a kind of pest that severely damages on Eucalyptus spp. as discussed by the authors The current research status in China of this pest including biological property, regularity of outbreak and damage,investigation and collection,pest risk analysis,prevention and management were outlined.
