It will depend on the kind of forest formation and composition. I could not get your point exactly . Are you talking about total above ground biomass or lopping / pruning of wood from the forest for fire energy ?

My research area is Bangladesh, so if I can get any reference regarding that region will be fine. I want to know is there any reference regarding fuelwood harvesting. It can be Above ground biomass or any study pointing directly to the amount of fuelwood. 

I have one paper uploaded in RG regarding utilisation of domestic fuel wood and its supply system however , it is basically from trees on agricultural fields and extra territorial collection from village boundary . We do not have any forest in Thar desert . If it could be any help to you , please down load from RG .Regards .

Fuel wood per ha depends on many factors like : species (fast, medium or slow growing); planting geometry ( close or wide ); Site factor (Climate, soil and topography).

In the northern lowlands of Guatemala, people collect fuelwood from so-called fallow (“resting”) swidden plots, so the impact of the collection is low.  There are several references that may help illuminate consumption, albeit not directly related to your question. I’m sure there are more up-to-date reports, perhaps from CATIE in Turrialba.

[1] Wiseman, F. W. 1978 Agriculture and Ecology of the Lake Region of Peten, Guatemala. PhD dissertation. Tucson: University of Arizona. (He reports on fuelwood use/supply for one of the towns located on the shores of Lake Peten Itza -good report and refers to usage before propane gas became so popular in the town, called, San Benito.)

[2] Mathewson, Kent 1984. Irrigation Horticulture in Highland Guatemala.  As I recall, he discusses fuelwood consumption in Panachel on pages 100-101.

[3] Jones, Jeffrey R. 1984.  The Central American energy problem: Anthropological perspectives on fuelwood supply and production. Culture and Agriculture # 22: 6-9.  Deals with all five CA countries at the national level. Good bibliography.

In 5 year old Eucalyptus grandis plantations in Paraguay, south America, we harvest up to 150 tons of fuelwood by thinning operations. In E.camaldulensis plantations volume per hectare at the same age is around 80 tons (E.camaldulensis is also much denser, 700 vs 400 kg/m3). This is in areas with up to 1800 mm rain and deep fertile soils. E.grandis together with E.urophylla are the fastest growing species in plantations down here. This is just an example for specific management and site conditions.

There is no straight forward answer to this question. It depends on many factors as rightly mentioned by Uthappa. So the answer cannot be generalized as shown by Claus Brehm.

As pointed by Rahman and Uthappa the wood harvested depends on various ecological and even socio-cultural factors. For instance, what one may consider as not being fuelwood (e.g. roots or below ground biomass), in one region, may be considered as good wood elsewhere. Generally in Kenyan highlands a hectare of E. grandis can produce about 170 tonnes from thinnings. And this is besides root biomass.

Fuel wood production will depend on woody species composition in a forest , the population structure of forest forming woody species , architecture of different  woody species , their basal area etc., etc. It will also vary from one  forest type to other.In plantations it will vary with tree species geometry and tree structural traits as mentioned by Dr. Uthappa.You can not generalise from one ha how much wood can be harvested.I do not think any one can give you any estimate.in this context.I sincerely request to learned fellows to stop the debate in this context.Do not take it otherwise.

Firstly fuel wood or energy crops are usually a fast growing tree species. Second site specific biomass difference also significantly influence. Moreover variety of tree is from hybrid or native stand is also work. Afterall management practices adopted for raising is also considerable point. In nutshell, it is a hard task to enumerate the biomass without measurement of a particular tree species at a specific site and specific environmental condition. Thus above mentioned points you may take in consideration for any rough assumptions. 

The amount of fuelwood that can be harvested from a forest depends on various factors, and you simply cannot use any empirical value unless it is developed by extensive field studies of the similar forest condition as of your study area. In Nepal the official guideline for the community forests to calculate the amount of fuelwood is “Community Forestry Resource Inventory Guideline”, this guideline describes in detail about the procedure to calculate the sustainable supply of the fuelwood from the community forest, which is based on the calculations that determines the Annual Allowable Harvest (AAH). Since this inventory guideline is made for the forests in Nepal (which is mostly a mountainous country) this might not be applicable as is in your case, however you can definitely take some guidance from it. 

I don’t know which paper you’re talking about, but this value is way too high for sustainable fuelwood harvest. What I would suggest for your situation is, if your study area is a vast forest area and more or less homogenous representing the same geographic and climatic conditions then you can simply carry out an inventory in a representative area of the forest and use that data to calculate the amount of fuelwood based on some control factor, that can be the quality of forest based on regeneration capacity and current timber stock.
