- Taxonomy, Distribution, and Conservation Status of Wild Guanaco Populations
Recent genome-scale results for wild and domestic SACs confirm the existence of two subspecies in both wild SAC genera: L g guanicoe and L g cacsilensis, and V v vicugna and V v mensalis (Fan et al 2020)
- Vicuña - GECS (Grupo Especialista en Camélidos Sudamericanos)
Since European settlement and the introduction of domestic herbivores, the total population has declined drastically At present, the total population is around 600,000 individuals (10% or less of the population existing 100 years ago) and has lost 60% of its original range
- #GUANACONECTA EN – guanaconecta. com
In the last two hundred years, it’s estimated that the guanaco population decreased from 10-30 million individuals to approximately 2 5 million Up to 90% of its original populations may have disappeared or been drastically reduced

Persecuted for their competition with livestock, guanacos are largely relegated to the driest lands that are not suitable for livestock While historical populations were widely migratory, most current groups are small and sedentary, confined by fences, livestock, and hunting
- Guanaco - Wild Expedition
Historically widespread, guanaco populations have been reduced due to hunting and habitat loss, but they remain relatively abundant in national parks and protected areas In addition to their mainland distribution, a small number of guanacos are present on the Falkland Islands
- Historical Perspective and Current Understanding of the Ecology . . .
In this chapter we compile, summarize, and analyze previously reported information on the social structure, behavior, population dynamics and genetics that provides a full and nuanced summary of our current understanding of the historical and modern biogeographic status of the guanaco in the Chilean Patagonia
- CSIRO PUBLISHING | Wildlife Research
Although the guanaco was abundant and widely distributed in the past, currently its density and distribution range are substantially reduced, inhabiting mainly Southern Patagonia in small isolated groups
- Modeling the Abundance and Spatial Distribution of the Guanaco
In this chapter, we review the different modeling tools employed to assess the status of guanaco populations throughout Argentinean and Chilean Patagonia, highlighting their advances, advantages, and limitations
