Habitat[ edit ] The Chacoan peccary is confined to hot, dry areas. A few scattered giant trees are found, but the majority of the vegetation is thorny scrub vegetation. The Chacoan peccary has developed adaptations such as well-developed sinuses to combat dry, dusty conditions. Their feet are also small, which allows maneuverability among spiny plants.

Sexual Maturity: Minimum breeding age is thought to be 3 years. Most births occur between September and November. During midday, they retire to the shadows of trees and bushes to rest. Chacoan peccaries frequently use dust baths and wallows. The distance vision and olfactory senses are well developed, although this peccary is not especially shy or wary.
When frightened, Chacoan peccaries flee, raising the long hairs on their back and spraying secretions from their dorsal gland, presumably to keep the group together in the dense brush via odor. These secretions are rubbed against group members, and are also used as territorial markers. The population density is calculated to be 9.
Family group: Solitary or in groups of animals of all ages and sexes. Diet: Cacti, roots, seed pods. Main Predators: Puma, jaguar. Remarks The largest peccary species, the Chacoan pronounced "cha-KOE-in" peccary was first described by Rusconi in Surprisingly, this description was made from fossil remains and the peccary assumed extinct, until when Dr. Ralph Wetzel, on an expedition to the Gran Chaco, discovered three types of peccary recognized by the natives: the collared and white-lipped peccaries and a larger third species.
Known locally as the tagua, this peccary is thought to be the most ancient, due to its small mental capacity and lack of adaptability. Literature Cited Nowak, R. Schmidt, C. Edited by S.

Freely accessible to everyone, over half a million people every month, from over countries, used Arkive to learn and discover the wonders of the natural world. Since Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Despite appeals for support, just 85 of our 5. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development. For many years, and in an attempt to keep Arkive online for years to come, Wildscreen investigated the possibility of transferring custodianship of the website to another environmental charity or institution but due to legal issues and the cost of doing so, we were unable to secure any support.
61. Chacoan Peccary
Each survival blueprint is compiled by an EDGE fellow working on the species with input from collaborators and stakeholders. Vision years Ensure viable populations of Catagonus wagneri in the Chaco eco-region, maintaining ecological integrity and environmental connectivity throughout its distribution, within a framework of sustainable development that addresses the needs and visions of local communities, valuing the species as emblem. Goal years The natural habitat of the species will be conserved and will be connected for populations to interchange individuals and existing populations are conserved. Objectives Give proper value to the Chaco ecosystems, ecosystem services and resources Critical The existing legal regulations are improved, regionally appropriate and applicable. There are no wild dogs High There is an updated record of individuals of Chacoan peccary in captivity with adequate control and inspection actions High Eradication of illegal hunting of the Chacoan peccary High There is no Chacoan peccary mortality associated with accidents or trampling High There is biological information on the species from captive breeding programs High There is a standardized system of monitoring the species and studies of habitat selection and occupation High There is a database of publications of about the Chacoan peccary High There is information available on the socio-economic value of the species and the different perceptions of different cultures on it High There is a standardized protocol for telemetry studies High Research appears on the agendas of National Research Institutions CONICET, CONACIT, Universities, government agencies of science, etc.
