While standard forest inventories, in which closed forest areas are
the major target objects, are well developed with respect to potential
sampling design options, there are many open questions when it comes
to the inclusion of other woody resources like small patches and
groups of trees or scattered trees outside the forest (TOF).
In the arid and ecologically vulnerable region of western China,
the tree resources outside the forest exert a significant function
in anti-desertification, and also in disaster prevention in general.
However, these tree resources are - as of yet - not integrated into
the forest inventories nor in the general forest management carried
out in this region.
Basic research is, therefore, required to develop adapted sampling
and response design options to allow efficient information procurement.
This is a Sino-German research project funded by DFG (Deutsche
Forschungsgemeinschaft) and NFSC (National Science Foundation of China).
