Figure 8.9 The Central American population of C. odorata exhibits considerable variation
in leaf phenology. The provenances are arranged in order of mean annual rainfall
that occurs in their native regions. The data was collected at the onset of the Spring rains
in March, J992.

tion of provenances optimally matched
with the agronomic calendar of understory
crops. Ideally, the period of leaf
fall should coincide with the flowering
and fruiting of commonly cultivated
understory crops to minimize light
competition. Long-term considerations
for provenance selection should include
wood quality, insect resistance (particularly
to Hypsipyla grandella), leaf phenology,
and wind resistance. Growing
C. odm'ata with a mix of tree species
aids in controlling pest and disease
problems and fits into the traditional
methods of silviculture already practiced
by the Haitian farmer. As site conditions
across the country become more
degraded, a shift to hardier provenances
may be required to sustain the productivity
of the species (Fig. 8.10).
