Research into Species of Cedrela and Swietenia in Honduras including Observations on Damage by Hypsipyla sp.

摘要

Preliminary results are presented for species of Cedrela and Swietenia, based on field observations and recent trials of CONSEFORH (Conservation and Silviculture of Honduran Dry Forest Species) in two experimental stations located in the central and southern dry zones of Honduras. These results include the initial effects of Hypsipyla sp. on C. odorata L. and S. humilis Zuccarini. Recent observations suggest the effectso fHypsipyla sp. on C. odorata L. and S. humilis Zuccarini. Recent observations suggest the presence of Hypsipyla sp. in a breeding seedling orchard of S. humilis. Recent attacks in a seed orchard of C. odorata and an enrichment planting of S. humilis in the central dry zone of Honduras are described. The distribution and conservation status of species of Cedrela and Swietenia in Honduras are briefly described. Species of these genera are valuable sources of sawn timber and round wood for rural people living in the dry zones of Honduras and have a long history of use of their durable timber. However, forest clearance and dysgenic selective harvesting have reduced and degraded the remaining natural stands. Current research and conservation activities are described. 'Conservation through use' by means of rural forestry programs with non-government organisations is currently perceived to be the most effective strategy for long-term conservation of these species. The paper concludes with an outline of future research opportunities and how the results will be used for Cedrela and Swietenia genera within Honduras.
