Infosylva forestry news clippings No. 09/2018 FAO - Publications - 1 week ago
With the objective of making forest concessions a more transparent, responsible and inclusive way to sustainably manage forests in the tropics, FAO has recently released the first voluntary guidelines for forest concessions in the tropics. At the the 13th session of the UN Forum on Forests, where the guidelines were launched, Eva Müller, Director of FAO's Forestry Policy and Resources Division, highlighted the multiple socio-economic and environmental benefits concessions can have if well managed,...
Contemporary forest planning has tasked managers with developing goals associated with resistance and resilience. In practice, silviculturists use forest structure and tree species composition to characterize goals and desired future conditions, write prescriptions, and monitor outcomes associated with resistance and resilience. Although rarely discussed in the exploding literature relating to forest resistance and resilience, silvicultural regeneration methods are important and underutilized tools...
Focusing on the underlying ecological mechanisms of dominant species regeneration in forest gaps at a landscape scale can provide detailed understanding for gap-based forest management. The individual effects of forest gaps or elevation on the regeneration of Abies faxoniana Rehd. et Wils. are well known, although elucidating how gap characteristics and elevation concurrently influence regeneration remains an important challenge. In this paper, we present an explorative study using structural equation...
Despite evidence that cocoa agroforests are composed of different types of associated plants leading to varieties of structures, few studies ... The post Profiling Carbon Storage/Stocks of Cocoa Agroforests in the Forest Landscape of Southern Cameroon appeared first on Center for International Forestry Research .
There are increasing calls in Africa for ‘sustainable intensification’ of agriculture with the aim of increasing productivity whilst minimizing the ... The post Retaining forests within agricultural landscapes as a pathway to sustainable intensification: Evidence from Southern Ethiopia appeared first on Center for International Forestry Research .
The conspecificity of Finnish and western Canadian isolates of the decay fungus Chondrostereum purpureum was investigated by several approaches, including the assessment of genetic variability, mating and progeny analysis, and the analysis of selected phenotypic traits. Eight second-generation single spore strains per fungal isolate pairing were investigated with specific genetic markers developed for both Finnish and Canadian parental isolates. Tests of link age disequilibrium were used to analyze...
National forest inventories (NFI) provide estimates of forest resources at the national and regional level but are also increasingly used as basis for mapping forest resources based on remotely sensed data. Such maps procure local estimates of forest resources but may also improve precision of national and regional estimates. Supported by a countrywide airborne laser scanning (circa 2014) and a national land-use map (circa 2014), direct (DI), model-assisted (MA), and model calibrated (MC) estimates...
Land cover 2.0 CFS - Publications - 1 week ago
Interest in knowing more about the Earth’s land cover and how it has changed over time motivated the mission and sensor design of early terrestrial remote sensing systems. Rapid developments in computer hardware and software in the last four decades have greatly increased the capacity for satellite data acquisition, downlink, dissemination, and end user science and applications. In 1992, Townshend reviewed the state of land cover mapping using Earth observation data at a pivotal point in time and...
The Colombian Andes foothills have seen an expansion of forest disturbance since the 1950s. While understanding the drivers of disturbance is important for quantifying the implications of land use change on regional biodiversity, methods for attributing disturbance to specific drivers of change at a high temporal and spatial resolution are still lacking in the Andes region, in part due to persistent cloud cover. Using 20 years of Landsat images (1996–2015) covering Picachos National Park in the...
Effective sustainable forest management for broad areas needs consistent country-wide forest inventory data. A stand-level inventory is appropriate as a minimum unit for local and regional forest management. South Korea currently produces a forest type map that contains only four categorical parameters. Stand height is a crucial forest attribute for understanding forest ecosystems that is currently missing and should be included in future forest type maps. Estimation of forest stand height is challenging...
