  Capybara (Hydrochaeris hydrochaeris) is the largest living rodent, widely distributed in South America, with a considerable potential as an economic resource. There are large populations in the region of Esteros del Ibera that could be exploited in a sustainable manner and contribute positively to the development of the region. Such exploitation requires to be done responsibly and following a specially designed management plan. In the particular case of wildlife management, a sustainable exploitation of a given species requires knowledge of its dynamics, its density in the area, and its vital rates, as well as understanding how the natural environment will respond to the proposed manipulation. It is also important to determine which environmental variables lead the population dynamics in each region. A mathematical model is a very convenient tool for analyzing possible strategies. This work presents a matrix population model structured in five stages. Sensitivity and elasticity analyses of the model provide an understanding of the effects of differentiated class-dependent survival and growth probabilities on the life cycle. A harvest term has been included in the model with the purpose of evaluating the sustainability of a given exploitation scenario or comparing different harvest strategies. The different strategies depend on the exploitation pattern, the exploitation intensity, and the season in which the harvest takes place. The purpose is to formulate a simple tool that can be understood by a manager without specific training. Hence, the software interface was specially designed for a user with elementary knowledge of vital parameters of the species.
