•Spanish Forest National Inventory + in detail inventory•Data available per diameter class:
–Stem volume o. and u. bark–Firewood volume–Stem weight–Crown weight–Leaves/needles weight
Estimating the resources’ availability
How much is it there, in the forests? Standing volume estimation
![Page 6: Fostering bioenergy from forests in Catalonia](https://reader034.vdocuments.mx/reader034/viewer/2022052617/54669347b4af9f3f3f8b5349/html5/thumbnails/6.jpg)

Growth values from the Spanish Forest Inventory:-Annual increment of volume o. and u. bark-Basic wood density of the species
Estimating the resources’ availability
How much are the forests growing? Which is the maximum potential?

-The ideal curve: combinate growth and exploitation periodicity (15-20 years) to estimate the annual sustainable potential-The wood overload at forest sites must be extracted, but this will mean more extractions at the beginning (risk of overestimation)
