Non-Timber Forest Products - Science topic

In our research area, when we are going to evaluate forest products produced and sold around the world, we usually use FAOSTAT. Are there other databases (in addition to FAOSTAT) that bring this information?

I want to understand if the extraction of NTFPs is considered as forest degradation or it is a way to even help conserve the forest since it may reduce the pressure on timber exploitation.

Methods used to measure NTF products

Type of data should be used

How to evaluate the linkage between forest regeneration and food security?

Any companies like fsc or similar to rainforest alliance

Dykstra (2002) says tropical native forests yield only about 30 m3/ha of timber, that is, about 10 trees/ha of many different species. And in parts of Africa it could be only about a tree per 10 ha. Compare that to temperate conifer forests which yield 500 m3/ha, so the costs of tropical forest exploitation (roads, skids, mapping, cutting of vines) amount to about 50 times more than in temperate forests. The Reduced Impact Logging (RIL) seems an oxymoron in the case of tropical native forests. In trials at Kalimantan concessions of Alas Kusuma Group (Suparma et al 2002), they found that it will be viable only if the regulators make it mandatory for the whole country, at a premium price for such timber. Currently, they get the work done through quantity based incentives with little supervision. RIL requires a total revamping of the system. My suggestion is that we apply a moratorium on road building and commercial logging in tropical native forests (allow only community-based, controlled, non-timber forest product exploitation) until such time air lifting of tropical timber becomes economically viable.

Is this method was applying in Horticulture or Agro-forestry systems ? Is this have any connection with physiological stress or evolution ?

What design of molecular techniques says about  the functional quality of a plant? Say for example if the plant is a timber yielding by its economics?

Can any one share the 10 Year Statistical Economical figures which support the communities and nation to build up this natural resource a new livelihood options and income in future?

According to my observation, 100 billet with diameter range 30-40cm can only get 50% recovery rate. The other 20% will be reuse as another type of plywood. While the other 30% were wasted. 

Different plants have different colonization history based on its economics.How rattan (family-Palmacea or Aracacea)  colonization connected with the historical era?

I am looking for researchers, engineers, scholars in Europe interested in partnering on a COST-ACTION around research topics on bamboo (Standardisation, LCA, Climate change, Markets, Biological engineering, etc).

In the provisioning forest ecosystem services the classifications used such as Timber and NTFPs, Woody and non woody products, Direct use values and indirect use values etc. For example; I have market values for the Timber (construction wood), house use furniture (chairs, tables, cupboards etc), fire/fuel wood, medicinal plants, thatching materials, and packing materials. How I should classify these forest products as Timber and NTFPs to avoid double counting? Which classification method for the provisioning  services of forest is valid and updated ?

I'm looking for an issue which develop

Apart from life cycle analysis.

If the harvesting rate is above the sustainable rate (ability to regenerating), the amount of next harvest season would be declined. To know the rate of sustainability , first we may need to know the total stock of those specific resources and its regenerating period. So, how we can measure the stock of those natural capital? or on a specific example of a Non-timber forest product? 

Hi, wondering if anybody can point me in the direction of some reliable non-wood-forest-product yield data in the temperate zone.

Specifically the production of Cherries (Prunus avium and domesticated cultivars), Walnuts (Juglans regia but also J. nigra etc.), Chestnuts (Castanea sativa, cultivars and related species) and finally Sorbus berries (Sorbus domestica, S.torminalis & S. aucuparia).

In the best case data on a 'per tree' basis relating yield to basic tree parameters (DBH/crown volume etc.) would be fantastic. More realistic would be values per hectare given a certain stocking density, prescribed management and information about the mean tree (as above DBH/crown parameters etc.). Furthermore, data covering a number of years would go a short way to negate fluctuating production due to external influence.

Can anyone help?

Much Appreciated

Have you seen any recent publications: such as modification of thinning/ harvesting regimes for the production of a certain NWFP species? Likewise, yield models for tree products (cherries walnuts etc.) any experience? I'd be interested to hear of anything from this growing research field, especially from experiences gained in Europe. Thanks

Model forests are one of the new topics that arise to assure forest sustainability, and so there are a lot of pilots in the Mediterranean basin dealing with non-timber products. The main objective was to integrate human impact on forests through timber harvesting which indeed break the forest ecosystem, and as a result CO2 sinks was decreased and global changes in climate takes place. What is your opinion about this subject?
