Understanding the possible changes of suitable habitats for wild animals in the context of climate change has important implications for creating relevant conservation policies in the future. Based on presence records of black muntjac (Muntiacus crinifrons), which were recorded from 1960s to current day, and nine species distribution models, we simulated black muntjac’s suitable habitat under the future climate scenarios. Future climate scenarios were derived from two greenhouse gas concentrations scenarios (RCP2.6 and RCP8.5), and two future time slices (2050s and 2080s). Results show that, by the 2050s and 2080s, under the scenario of RCP2.6, areas of the suitable habitat of black muntjac will decrease by 11.9% and 6.2%, respectively, while under the scenario of RCP8.5, they will decrease by 36.9% and 52.0%, respectively. Under the scenario of RCP2.6, the areas of ‘core’ landscape for the suitable habitat of black muntjac will decrease by 20.5% and 10.5%, while under the scenario of RCP8.5, they will decrease by 55.2% and 65.2%, respectively. Under the scenario of RCP2.6, the proportion of stable suitable habitat to the suitable habitat under baseline climate conditions are 75.1% and 84.2%, while under the scenario of RCP8.5, they are 48.3% and 35.8%, respectively. In general, using the scenario with RCP2.6, the effects of future climate change on suitable habitat of black muntjac are minimal. In contrast, under the scenario of RCP8.5, the future climate will have drastic effects on suitable habitat for black muntjac. In particular, the area of suitable habitat and its ‘core’ landscape will significantly decrease, and so will the proportion of stable suitable habitat to the suitable habitat under baseline climate conditions. Therefore, we propose to conserve suitable habitat for black muntjac in the border area of Zhejiang, Anhui, and Jiangxi provinces, and to build corridors to connect different nature reserves for black muntjac.
