multipurpose tree species research for small farms: strategies ... - part

supporting research.
The eastern part of Indonesia should be declared a
priority zone, particularly in the semi-arid areas of
Nusa Tenggara Barat and Nusa Tenggara Timur
province. Results of studies in these areas can be
compared with findings ia similar ecosystems of
Asia. Studies should also be carried out in the
humid areas of Indonesia.
Sampling Method
The stratified random sampling method is
recommended in the selection of respondents.
Stratification can be applied on the basis of the
extent of land ownership, because land is still the
principal source of income for villagers.
The number of respondents should be
determined based on a preliminary sample, to
predetermine the level of the allowable sampling
error. To achieve uniformity, the level of the
predetermined sampling error should be the same
at all study locations, and for cross-cultural studies.
Length of Research
Research in the field should be carried out for
at least three months. This should be distributed
during the transition of seasons from wet to dry
and vice versa, to record the a:ctivities and
conditions in the study village and for comparison
with the previous season. This plan allows enough
time to become familiar with the locale and the
people, to study the households in general, and
observe the level of end uses of tree products by
villagers.
Quantification of Data
To study the level and end uses of MPTS,
quantitative measurements may be necessary.
Research instruments need to be designed so that
quantitative data on the level of tree product use
can be collected. Conclusions can then be drawn
about the level of dependency of households on the
available trees, and correlated to the number of
trees that should be planted in the homcgarden to
meet household needs sustainably.
Inventory of Tree Potential
Data on tree potential in the village is necessary
to crosschcck the outcome of the interviews. The
data can also be used to evaluate whether the level
of tree potential can supply the needs of all the
villagers, and whether the existing trees can reach
the level of the theoretical potential.

Herbarium
For dominant or preferred species in the study
villages, herbarium material should be prepared
and kept for the srke of accuracy in recognizing
the snecies.
