The paper thinks, the main characteristics of the non-observed forestry economy are producibility, the coexistence of illegality and legality, the coexistence of invisibility and publicity, the limiting of accounting technique and so on; the main reasons for the non-observed forestry economy in that it has the common factors of general non-observed economy as well as the special factors in forestry; according to the characteristics of forestry industry and the availability of data, the method of balance between supply and demand, the method of adjusting census' data, the method of using matter's quantity and the method of freight traffic are proposed as some applicable methods on estimating the non-observed forestry economy. In case, the scale of non-observed forestry economy is estimated with the method of balance between supply and demand and the method of adjusting census' data. At last, the paper gives advice on the solutions of nonnegligible non-observed forestry economy in fact.
