“…We collected presence records for elephants within the SYR population during the past 2 decades, which we subdivided into 2000-2010 and 2011-2020. Records from the earlier period included published data collected between 2000 and 2010 (Feng and Zhang 2005;Zhang 2006;Wang et al 2007;Lin et al 2008Lin et al , 2011Lin et al , 2014Yang and Zhang 2012), while the presence data from the later period was derived from post-2010 published records (Zong et al 2014, Li et al 2017, Bai et al 2018, genetic capture-mark-recapture sampling, and motion-sensitive camera surveys. We spent 4 months from December 2015 to March 2016 searching for fresh years according to equipment, manpower, and funding.…”

“…We chose the camera locations by following trails used by elephants and placed cameras at sites with abundant signs of elephants (footprints, feces, scrubs, feeding sites, or sleeping signs), and (as far as possible) distant from human activity in areas with gentle slopes, ranging in altitude from 600 m to 1,700 m. We retrieved images at monthly intervals. Further details of camera deployment are provided by Bai et al (2018) and Yang et al (2018). We did not include elephant-presence locations extracted from human-elephant conflict incidents, such as those available in Chen et al (2016), because we intended to model the extent of suitable natural habitat without the bias introduced by a high proportion of occurrence points in cropland where temporary food resources lure elephants (Lin et al 2015).…”

“…The southern boundary of SYR abuts with Lao PDR, formerly allowing some of these elephants to move between China and Lao PDR (Yang et al 2018). Shangyong Reserve also provides habitat for the Indochinese leopard ( Panthera pardus delacouri ), clouded leopard ( Neofelis nebulosa ), and dhole ( Cuon alpinus ; Bai et al 2018).…”

Conservation interventions for threatened species must be based on accurate assessments of the effects of anthropogenic pressures on habitat suitability. We used multiscale multivariable species‐distribution modeling to evaluate habitat suitability for an Asian elephant (Elephas maximus) population in Shangyong Reserve, Yunnan Province, southwestern China. We investigated the scales at which measurements of environmental variables best reflected elephant habitat selection, and examined whether these responses changed over 2 decades (2000–2010 and 2011–2020) in response to 20 environmental variables, including 14 variables reflecting landscape fragmentation, the extent of buildings, and transport infrastructure. Elephant presence was sensitive to the scale of each variable, and the effects differed among variables within and between decades. More than half of the variables influenced elephant presence at coarse scales of 8 or 16 km, including 12 variables reflecting anthropogenic pressures in 2000–2010 and 10 in 2011–2020. Overall, multivariate models with variables at their optimal scales had higher discrimination than models at uniformly fine scales of 1 km or 2 km. The extent of suitable habitat for elephants declined by 24% over 2 decades. Less than half of elephant habitat was located within Shangyong Reserve (49% in 2000–2010, 40% in 2011–2020), indicating the importance of managing suitable habitat beyond reserve boundaries. Roads and buildings reduced the probability of elephant presence, with effects that extended beyond their immediate footprint. We advocate that infrastructure be planned with buffers, ≥8 km wide, between roads or buildings and core elephant habitat. Multiscale multivariable species‐distribution modeling should be employed to ensure that all suitable habitat for the remaining fragmented elephant populations in Yunnan is identified, mapped, and protected.

“…Nevertheless, this represents the first confirmed record of the species in China in 45 years. Other recent reports of sun bears in China (Zhou et al 2017, Bai et al 2018 were misidentifications of Asiatic black bears. Sun bears were thought to be extirpated in Bangladesh, with the exception of a few vagrants from neighboring countries (Islam et al 2013), until confirmed records (dead animals and camera-trap photos) were obtained in the Chittagong Hill Tracts during 2014-2016, including a female and cub (Anwarul Islam, WildTeam, personal communication 2015;Creative Conservation Alliance 2016;Hasan Rahman, personal communication, 2017).…”

“…From 1972 to 1990, humans and elephants frequently made contact [12]. From 1991 to 1995, the conflict between humans and elephants intensified [13]. From 1996 to 2005, Asian elephants were strictly protected, but serious accidents also occurred [14].…”

The population development of Asian elephants (Elephas maximus) has been greatly affected by the intensification of human activities. In this study, development of the Asian elephant population under the influence of human disturbance was analyzed logically, with expansion of the rubber forest area as the main influencing factor. The ecological–economic model of Asian elephant population development was constructed using the logical analysis method, the population growth model and the integrated environmental–economic control model. The results are as follows: (1) Theoretically, the ecological–economic model could be applied to the analysis of wildlife conservation and regulation and management policies; (2) The data show that in 2016, the intrinsic growth rate of Asian elephants in Xishuangbanna was 0.0216 head/day, which has a strong proliferation capacity, meaning the population will continue to grow under natural conditions. However, at present, the population development of Asian elephants has been negatively affected by human interference, which has reduced the population growth rate of Asian elephants to 0.0193 head/day, and this impact has a tendency to intensify; (3) From 2004 to 2016, the investment rate of Asian elephants increased by 0.182, while the anti-interference protection rate of Asian elephants decreased by 0.227. The overall development trend of Asian elephants was from equilibrium point one (golden age) to equilibrium point two (dark age).
