Simple Summary The Malayan tiger, with less than 200 individuals in Malaysia, is in an intermediate population crash. Anthropogenic disturbances (poaching, roadkill, and human-tiger conflict), environmental perturbation (decreasing habitat quality), and infectious diseases have been identified as factors leading to impending extinction. Preliminary findings from stakeholders indicate Peninsular Malaysia has an existing Malayan Tiger conservation management programme. However, to enhance the protection and conservation of the Malayan Tiger, the authority should re-assess the existing legislation, regulation, and management plan, and realign them to prevent population decline. The critically endangered Malayan tiger (Panthera tigris jacksoni), with an estimated population of less than 200 individuals left in isolated rainforest habitats in Malaysia, is in an intermediate population crash leading to extinction in the next decade. The population has decreased significantly by illegal poaching, environmental perturbation, roadkill, and being captured during human-wildlife conflicts. Forty-five or more individuals were extracted from the wild (four animals captured due to conflict, one death due to canine distemper, one roadkilled, and 39 poached) in the 12 years between 2008-2019. The Malayan tigers are the first wildlife species to test positive for COVID-19 and are subject to the Canine Distemper Virus. These anthropogenic disturbances (poaching and human-tiger conflict) and environmental perturbation (decreasing habitat coverage and quality) have long been identified as impending extinction factors. Roadkill and infectious diseases have emerged recently as new confounding factors threatening Malayan tiger extinction in the near future. Peninsular Malaysia has an existing Malayan tiger conservation management plan; however, to enhance the protection and conservation of Malayan tigers from potential extinction, the authority should reassess the existing legislation, regulation, and management plan and realign them to prevent further population decline, and to better enable preparedness and readiness for the ongoing pandemic and future threats.
