Assessments of forest biodiversity - the diversity within forest species, between species and of forest ecosystems - are essential if forest resources are to be effectively conserved and sustainably managed (Hunter, 1999). Assessments are needed to provide information necessary to support biodiversity-related decision-making in forest policy and management. However, assessment of forest biodiversity presents a number of challenges. First, because of the complexity of biodiversity, information about it needs to be assembled and expressed based on simplified variables, typically in the form of indicators (Noss, 1990, 1999). Second, since decisions relating to forests are made at a variety of scales, biodiversity data and indicators need to be aggregated across different scales for monitoring and reporting purposes (Noss, 1990; Turner, 1995).Resource Type: Journal Papers
REDD+, as discussed by the United Nations Framework Convention on Climate Change, is a mechanism to incentivise Reducing Emissions from Deforestation and forest Degradation, as well as the conservation of forest carbon stocks, sustainable management of forests and the enhancement of forest carbon stocks. Actions under REDD+ can potentially provide biodiversity benefits, but there is also a need to avoid any risks of environmental harms from REDD+. A new report, launched in Kinshasa on 5 July 2012, presents selected results of spatial analyses to explore potential biodiversity benefits and risks from REDD+ in the Democratic Republic of the Congo. The report is the output of a collaboration between the DRC’s Direction des Inventaires et Aménagement Forestiers (DIAF) of the Ministère de l'Environnement, Conservation de la Nature et Tourisme, the Observatoire Satellital des Forêts d’Afrique Centrale (OSFAC) and the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), with support from the UN-REDD Programme.Resource Type: Reports
At the 9th meeting of the SBSTTA of the CBD a recommendation was made to begin testing of five biodiversity indicators in order to measure progress towards the 2010 target. This paper considers one of these indicators for Pan-Europe. The basic principle of the index is to calculate the average trend in abundance of a set of ecosystem-representative species. The index is considered to be generic, i.e. applicable to all ecosystem types including forests. It can produce both headline messages for high-level policy and communication, and detailed information for in-depth analysis. This paper describes the conceptual framework of the index and explores the data availability for the index in Pan-Europe.Resource Type: Journal Papers
This review focuses on woody bamboos with the highest diversity recorded in the Asia-Pacific region where bamboos play a major role in ecosystem dynamics in many forests.
The genetic diversity of the remaining forest bamboos, of which many are highly susceptible to deforestation, is of great concern and an accurate information base is required as a foundation for policy and management decisions affecting bamboo. A programme to strengthen the Red List assessments of bamboo species status is also needed, one that prioritizes the assessment of species with the smallest estimated geographical ranges and least remaining habitat.Resource Type: Journal Papers
The forests of eastern Tanzania are a globally important biodiversity hotspot. In this study 361 eastern Tanzanian restricted range forest tree taxa were assessed. Of these taxa, 223 occurred in the Eastern Arc, 150 in Coastal forests, 17 in Northern forests and 21 in the Lake Nyasa forests. The majority of the taxa had restricted elevational ranges with 76.3 occurring in no more than two 200 m elevational bands out of a total potential elevation range of 3000 m. The majority of the taxa occupied a small area in the eastern Tanzanian forests, with 201 taxa being only found at a few sites. In determining priority areas for conservation, selection of taxon definitions can have important effects. For example, tree size varies with elevation, so if only large trees are used then site selection will be biased towards particular areas.Resource Type: Journal Papers
Tropical trees in the genus Aquilaria Lam. are the principal source of gaharu, one of the most valuable forest products traded internationally. Although these species are the focus of increasing conservation concern, information on their status and distribution is lacking. Information from herbarium accessions, a national forest inventory (NFI), field surveys and gaharu traders was used to assess the distribution of Aquilaria species in Indonesia, indicating population concentrations in Sumatra and eastern Kalimantan.
Given current deforestation rates, these data suggest that all Aquilaria species in Indonesia classify as Vulnerable according to the IUCN Red List criteria.Resource Type: Journal Papers
To maintain the greatest resilience of Amazonian biodiversity to climate change as modelled by HADCM2GSa1, highest priority should be given to strengthening and extending protected areas in western Amazonia that encompass lowland and montane forests.Resource Type: Journal Papers
Although trade in non-timber forest products (NTFPs) has been widely promoted as an approach to rural development, recent research has indicated that NTFP commercialisation is often not successful. Analysis of the factors influencing success of NTFP commercialisation has been hindered by the lack of an appropriate analytical approach for comparison of case studies. We tested and further developed a methodology recently developed by CIFOR, by examining 16 NTFP case studies in two workshops held in Mexico and Bolivia involving a variety of stakeholders involved in NTFP commercialisation.Resource Type: Journal Papers
Virtually all of the tropical dry forests that remain are currently exposed to a variety of different threats, largely resulting from human activity. Taking their high biodiversity value into consideration, this indicates that tropical dry forests should be accorded high conservation priority. The results presented here could be used to identify which forest areas should be accorded highest priority for conservation action. In particular, the expansion of the global protected area network, particularly in Mesoamerica, should be given urgent consideration.Resource Type: Journal Papers
Fagus grandifolia var. mexicana (Mexican beech) is limited to about 10 populations (2-35 ha) in the Sierra Madre Oriental, Mexico. The objectives were to assess the current status and distribution of beech by surveying five sites. Species richness varied between three to 27 tree species in the canopy, and from nine to 29 species in the understorey. Basal area of trees greater than or equal to 5 cm dbh varied between 27.87 and 70.98 m2 ha-1, and density from 370 to 1290 individual ha-1. Beech represented 22-99.6 of total basal area, and 6.8-83.3 of total density. Beech dominance varied from monodominant to codominance with Carpinus caroliniana, Quercus spp., Liquidambar styraciflua, Magnolia schiedeana, and Podocarpus spp. Beech total population size ranged from 180 to 6300 trees with a total of less than 1300 individuals in four sites. Anthropogenic disturbance remains a major threat to these forests. It is uncertain whether Mexican beech will be able to survive without conservation efforts.Resource Type: Journal Papers
