Abstract
This paper reviews the causes of declining wild tiger populations. These populations have been rapidly declining in the last 100 years and of eight subspecies of tigers, only five are left. As an umbrella species, they are an important factor within their ecosystems, but poaching, prey depletion, and loss of habitat are pushing wild tigers towards extinction. There is little research on the consequences of allowing wild tigers to go extinct in terms of trophic cascade.

Introduction
In the last century, the population size of wild tigers has dropped (Wikramanayake et al, 2011), and tigers may soon go extinct altogether. Research has shown that poaching, prey depletion, and loss of habitat are causing tiger populations to decrease. In this paper I provide an overview of the current status of wild tigers, the reasons for decreasing tiger populations, and conclude with a suggestion for future research that will lead to a better understanding of the consequences of wild tiger extinction.

Status and Decline of Wild Tiger Populations
Wild tiger populations can be found in Bangladesh, Bhutan, Cambodia, China, Indonesia, Laos, Malaysia, Myanmar, Nepal, Russia, Thailand and Vietnam. Of the eight original subspecies, three, the Bali, South Chinese, and Javan tigers, have gone extinct in the last 80 years. Dasgupta et al (2014) developed a resource-allocation model…
