Since the 1800s, brocket deer have been an important source of meat and income for subsistence and professional hunters in the Peruvian Amazon. Today, local people continue to hunt brocket deer for subsistence meat and for sale in local meat markets. Although brocket deer are not hunted as frequently as peccaries, they make a significant contribution to rural household economies. This study assessed the sustainability of hunting of brocket deer by local communities in the Tamshiyacu Tahuayo Communal Reserve (TTCR), northeastern Peru. We analyzed data from 1991 to 1999 using density comparisons, hunting pressures, an age structure model, and a harvest model comparing results between heavily hunted, slightly hunted, and non-hunted sites. The four approaches agreed that brocket deer are harvested sustainably. The sustainability of brocket deer hunting will depend on the continued presence of other valuable wildlife species (e.g. peccaries and large rodents), which are more preferred due to their ease of hunting and higher rates of encounters. Gross productivity indicates that brocket deer are showing resilience in the form of density dependent reproductive adjustments in the TTCR, but they may still be vulnerable to overhunting. Consequently, current levels of harvesting may be continued until further ecological and biological information on the species' population trends assist in defining more reliable sustainable offtake levels. © 2003 Elsevier Ltd.
