ArticleJournal articleTree diversity, stand structure and community composition of tropical forests in Dalma Wildlife Sanctuary of Jharkhand, India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Species diversity and density of trees were assessed in forests of Dalma Wildlife Sanctuary of Jharkhand comprising mostly of tropical deciduous forests. We compared tree community characteristics like stem density, basal area, diversity index, Beta(β diversity), Girth class, Canopy height class and species composition of tree species in all three zones ( Altitude between 199 -603m) in the study area. A total of 41 tree species of 25 families, 71 genera, and 95 species were recorded. Gramineae (10) family is most represented followed by Euphorbiaceae(6). It was noticed that the tree density varied from 30.64 to 62.51. The maximum basal area contributed by Terminalia belerica(1.323 m2ha-1) followed by Albezzia stipulate(1.145 m2ha-1). Shannon Weiner index (H’) ranged from 3.073 to 3.997 and species richness index ranged from 1.05 to 1.20. Beta diversity of tree species varied from 2.32 to 3.80. The highest number of tree species was occurred in girth class of 61 – 80 cm in all three zones. At present the biodiversity of these forests are under threat due to the anthropogenic and illegal interference of outside people for cutting of furniture tree species. The present study will help us to understand the patterns of tree species composition and diversity in the Dalma Wildlife Sanctuary, of India.

No results found.Bush encroachment is a serious land degradation phenomenon affecting up to 45 million hectares of Namibian land and has severe negative consequences on key ecosystem services, threatening biodiversity, water resources and the livelihoods of communities and farmers who depend on the land. It has led to decreased biodiversity, degradation of the functions and structures of ecological ecosystems, lowering the grasslands’ carrying capacity, displacement of wildlife, as well as impacting groundwater recharge. Encroachers include species such as Senegalia erubescens, S. fleckii, Vachellia nilotica, V. luederitzii, V. reficiens, Colophospermum mopane, Rhigozum trichotomum, Terminalia prunioides, T. sericea, S. mellifera, and Dichrostachys cinerea.
The Forest Stewardship Council (FSC) is an international organisation promoting responsible forest management. FSC has been certifying forest management in savanna woodland and timber products produced such as charcoal in Namibia for 19 years, and has seen a rapid increase in forest management certification over the last 3 years. The poster will highlight the enabling conditions which contributed to the growth of approximately 1.5 million hectares (841%) of responsibly managed restoration efforts on FSC certified land in Namibia. This will include information on the FSC forest stewardship standard for Namibia developed by Namibian experts and stakeholders. The standard is focused on restoration of degraded forests and effective after-care measures and improved working conditions for workers. Information will also include supply chain integrity in charcoal supply chains from Namibia to European markets; biodiversity conservation via ecosystem services certification, development and implementation of user friendly technology to assist farmers with sustainable forest management practices and knowledge transfer; and how the use of materials developed by partners have assisted with best practices and local capacity development.

ArticleJournal articleThe influence of over-mature, degraded Nothofagus forests with strong anthropic disturbance on the quality of an andisol and Its gradual recovery with silvopasture in southwestern South America

No results found.The increasing demand for timber and non-timber products from native forests in Chile and the cattle grazing has augmented the rate of degradation of these ecosystems. This process results in the need to know which of the dynamic variables are involved in its regulation. Soil quality indicators like soil organic carbon (SOC), soil microbial respiration (SMR), microbial biomass carbon (MBC), potential net N mineralization (N-min), and nitrification (N-NO), soil aggregates, and light fraction (LF), were evaluated at two different depths of the soil in Nothofagus obliqua (deciduous) and mixed N. dombeyi - N. obliqua (evergreen-deciduous) forests, where a 30- ha silvopastoral trial was established, after this evaluation, in early 2016. The SOC, SMR, MBC, N-min and N-NO were significantly higher in the N. obliqua forest than the mixed forest, 8%, 17%, 17%, 40%, 20%, respectively (p<0.05). The dry weight in soil fractions did not present differences between forest types. C and N contents in the LF (labile, un-decomposed organic matter of plant origin) were higher in the deciduous forest, 9% and 20%, respectively (p<0.05). Our results suggest that soil quality was favored by the quality of organic matter in the site dominated by deciduous species, which translates into more favorable conditions for the activity of microorganisms, nitrogen dynamic, and C and N content in the light faction. The intrinsic characteristics of the plant residues associated with higher rates of decomposition, can stimulate the activity of the biota and especially the soil microorganisms, which would lead to higher values of the different indicators evaluated. This novel silvopastoral system will likely help restore the most degraded sites through improvement of the soil quality. This kind of information allows obtaining knowledge of the forest areas and their sustainability, mainly for the planning of long-term, durable silvopastoral practices.

Book (series)Technical bookMediterranean coastal lagoons: sustainable management and interactions among aquaculture, capture fisheries and the environment 2015
Also available in:
No results found.The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons’ ecolog ical features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons’ environment. -
