Matschie's tree kangaroo (Dendrolagus matschiei), New Guinea pademelon (Thylogale browni), and small dorcopsis (Dorcopsulus vanheurni) are sympatric macropodid taxa, of conservation concern, that inhabit the Yopno-Urawa-Som (YUS) Conservation Area on the Huon Peninsula, Papua New Guinea. We sequenced three partial mitochondrial DNA (mtDNA) genes from the three taxa to (i) investigate network structure; and (ii) identify conservation units within the YUS Conservation Area. All three taxa displayed a similar pattern in the spatial distribution of their mtDNA haplotypes and the Urawa and Som rivers on the Huon may have acted as a barrier to maternal gene flow. Matschie's tree kangaroo and New Guinea pademelon within the YUS Conservation Area should be managed as single conservation units because mtDNA nucleotides were not fixed for a given geographic area. However, two distinct conservation units were identified for small dorcopsis from the two different mountain ranges within the YUS Conservation Area.
马氏树袋鼠（Dendrolagus matschiei）、新几内亚林袋鼠（Thylogale browni）和小多氏袋貂（Dorcopsulus vanheurni）是同域分布的有袋类动物分类群，受到保护关注，它们栖息在巴布亚新几内亚胡昂半岛的约普诺 - 乌拉瓦 - 索姆（YUS）保护区。我们对这三个分类群的三个线粒体DNA（mtDNA）部分基因进行了测序，以（i）研究网络结构；以及（ii）确定YUS保护区内的保护单元。所有这三个分类群在其mtDNA单倍型的空间分布上都呈现出相似的模式，胡昂半岛上的乌拉瓦河和索姆河可能对母系基因流动起到了屏障作用。由于mtDNA核苷酸在给定地理区域内并未固定，YUS保护区内的马氏树袋鼠和新几内亚林袋鼠应作为单一保护单元进行管理。然而，在YUS保护区内的两个不同山脉中，为小多氏袋貂确定了两个不同的保护单元。
