Native and Endangered Timber Tree Species in Homegardens of Northeast and Northcentral Viet Nam

Homegardens are receiving increasing attention for in-situ plant genetic conservation in biodiversity conservation programs. To inform authorities and conservation stakeholders, we investigated the diversity and provenance type of tree species in 120 homegardens in Northeast and Northcentral Viet Nam. The study showed that ten of sixteen recorded timber trees are native to the country, including one (Aquilaria crassna) classified as ‘critically endangered, two ‘endagered’ (Erythrophleum fordii and Parashorea chinensis), and one ‘vulnerable’ (Dalbergia tonkinensis), according to the global Red List of threatened tree species. The study provides evidence for the potential role of homegardens as plant genetic source and in-situ conservation, and we recommend that the Government of Viet Nam recognizes this opportunity through support programs for diversification and domestication of native tree species for homegardens.

家庭庭园（homegardens）作为原位植物遗传保护的载体，在生物多样性保护项目中的关注度与日俱增。为向主管部门及保护利益相关方提供决策依据，本研究对越南东北部及中北部地区的120处家庭庭园开展调查，分析其中树木物种的多样性与种源类型。研究结果显示，本次调查记录的16种用材树种中，有10种为越南本土原产树种；依据全球濒危树木物种红色名录，其中1种（Aquilaria crassna）被列为极危物种，2种（Erythrophleum fordii与Parashorea chinensis）被列为濒危物种，1种（Dalbergia tonkinensis）被列为易危物种。本研究为家庭庭园作为植物遗传资源库与原位保护载体的潜在作用提供了实证支持，并建议越南政府通过相关扶持项目，推动本土树种在家庭庭园中的多样化种植与归化培育，以把握这一保护契机。
