The IUCN Red List of Threatened Species is an extinction risk assessment tool that has guided species conservation over the last five decades. However, as wildlife scientists and conservationists, we argue that its influence on the global conservation agenda can hinder effective species conservation efforts. Here, we review the limitations of the Red List and its misuse in priority setting, which can overlook local and regional contexts. This can result in improper allocation of conservation resources, especially in the Global South, where financial resources are limited. In particular, funds directed towards red-listed species may fail to address a broader range of conservation priorities. We also contend that extinction risk is insufficient for guiding conservation efforts and recommend broadening conservation planning and decision-making beyond reliance on the Red List. Thus, for a more inclusive and decentralized approach, we summarize guidelines for guiding species conservation at appropriate ecological, spatial, and taxonomic scales. Finally, we encourage more collaborative efforts and stakeholder engagement for the setting of conservation priorities and efficient funding allocation.

Despite decades of field study, very little is known about the molecular ecology of gibbons, particularly as it relates to their ability to disperse across degraded and fragmentary landscapes. The critically endangered western black crested gibbon (Nomascus concolor) has been reduced to a small, fragmented population with about 1300 individuals. In the largest population genetic study of free‐ranging gibbons to date, we sampled 47 of these gibbons from 13 sites in China and generated 15 polymorphic autosomal microsatellite markers. We identify three population clusters of N. concolor in Yunnan centered in 1) the Wuliang and Ailao Mountains, 2) the Yongde Daxueshan Mountains, and 3) an isolated remnant near the border with Vietnam. Within the Wuliang Mountains, we identified four subclusters, three of which are bounded by high‐altitude rhododendron forest, and one that is isolated from the main population by ~2 km of degraded forest and pasture. Least‐cost path analysis and isolation by resistance modeling demonstrates that the population genetic distances among gibbons in Wuliangshan National Nature Reserve are significantly correlated with geographic paths that avoid use of high‐altitude rhododendron forest in favor of evergreen broadleaf forest. Although these gibbons have likely undergone reductions in heterozygosity from recent consanguineous mating, we suggest that their active avoidance of inbreeding on the population level maintains higher than expected levels of genetic diversity. This research provides new insights into how gibbons interact with heterogeneous environments and expands our understanding of their molecular ecology and conservation genetics.

Hylobates moloch (Audebert, 1797), the Javan or silvery gibbon, is a pair-living small ape which is exclusively found in the western and central regions of the Indonesian island of Java. It represents the southernmost occurring species of the genus Hylobates and inhabits the canopy of tropical rainforests. It is foremost characterized by its long silvery-gray fur in combination with a lack of duet songs in mated pairs. Hylobates moloch is threatened by habitat loss as well as the illegal wildlife trade and is listed as “Endangered” (EN) by the IUCN Red List of Threatened Species.
