Description The Blue-throated Macaw (Ara glaucogularis) is an endemic and endangered bird species. It inhabits palm forest islands that are scattered over the savanna in Beni, Bolivia. The savannas of Beni are inundated each year, and these palm �islands� occur at places that are topographically a little higher. Centuries of intense cattle ranching, deforestation and burning has affected the savanna of northern Bolivia. To protect this ecosystem, its biodiversity and the macaw we need to understand what savanna conditions provide the highest biodiversity, palm and macaw abundances possible. There are a lot of conflicting views on the effects of cattle grazing and associated management practices, such as burning. Do they threaten the stability of the savanna ecosystem or not? What plant and animal species are affected by grazing and burning? Is it better to have a homogenous savanna of old age, or a mosaic of grass patches in different development stages? These questions can be addressed by using a �natural expriment�. In 2012 and 2014 several parts of the Barba Azul Nature Reserve have been burnt by fires created by surrounding farms, creating a variety of savanna age-classes.
