“…For example, in the Sabana de Bogota (Colombia) the presence of Amerindians could be established from 12 500 yr BP (14 800 cal. yr BP) onward and possibly even before that time (Van der Hammen and Urrego, 1978). It is somewhat speculative, but it is possible that fires on the El Tiro mountain slopes originate from anthropogenic fires by hunting activities in the savanna or dry forest area of the dry Loja basin after 8000 cal.…”

In order to study the stability and dynamics of mountain rainforest and paramo ecosystems, including the biodiversity of these ecosystems, the Holocene and late Pleistocene climate and fire variability, and human impact in the southeastern Ecuadorian Andes, we present a high-resolution pollen record from El Tiro Pass (2810 m elevation), Podocarpus National Park. Palaeoenvironmental changes, investigated by pollen, spores and charcoal analysis, inferred from a 127 cm long core spanning the last ca. 21 000 cal. yr BP, indicate that grass-paramo was the main vegetation type at the El Tiro Pass during the late Pleistocene period. The grass-paramo was rich in Poaceae, Plantago rigida and Plantago australis, reflecting cold and moist climatic conditions. During the early Holocene, from 11 200 to 8900 cal. yr BP, subparamo and upper mountain rainforest vegetation expanded slightly, indicating a slow warming of climatic conditions during this period. From 8900 to 3300 cal. yr BP an upper mountain rainforest developed at the study site, indicated by an increase in Hedyosmun, Podocarpaceae, Myrsine and Ilex. This suggests a warmer climate than the present day at this elevation. The modern subparamo vegetation became established since 3300 cal. yr BP at El Tiro Pass. Fires, probably anthropogenic origin, were very rare during the late Pleistocene but became frequent after 8000 cal. yr BP.

“…Relatively high lake levels, on the other hand, generally prevail.ed during the colder glacial periods when the surrounding slopes were covered with paramo vegetation dominated by Gramineae. The fluctuations in lake level are explained by differences in evaporation under warm and cold climatic conditions (Hooghiemstra, 1984;van der Hammen, 1988), and by differences in interception, evapotranspiration and water storage of forest and open vegetation types (Kuhry and Helmens, 1990;Kuhry, 1991). In addition to the influence upon vegetation cover and lake level, the phases of climatic cooling caused glaciers to form and expand in the highest mountain ranges around Bogotfi.…”

“…van der Hammen et al, 1980/81;Helmens, 1988;Helmens and Kuhry, in press). Fossil bones of Mastodon have been found in silty slope deposits of Late Pleniglacial and Late Glacial age (de Porta, 1961;van der Hammen, 1965van der Hammen, , 1981, whereas the presence of early man in the Late Glacial and Holocene is, among others, recorded in findings of artefacts (van der Hammen and Correal, 1978). Figure 9 shows the distribution of forest, dwarf forest of Polylepis, grass paramo and xerophytic vegetation, and glaciers in the Eastern Cordillera near Bogota during different periods of the Last Glacial-Interglacial cycle (van der Hammen, 1981).…”

“…Human settlement of the Sabana de Bogotá (Figure 1c) began at the end of the Pleistocene (van der Hammen and Correal-Urrego 1978). The earliest absolute (radiocarbon) date of 15,133–13,999 cal BP 2σ (GrN-5556; Hurt et al 1976:5) comes from the El Abra rockshelter.…”

A Macaw (Ara sp.) in a Preceramic Site from the Sabana de Bogotá, Colombia, Dated to the Ninth Millennium cal BP

The attribution of osteological remains of a bird discovered in Preceramic deposits at Nemocón IV rockshelter (Sabana de Bogotá, Colombia) to Ara sp. (macaws) is confirmed through osteological and morphometrical analyses. Thirteen bones were recovered from two adjacent, arbitrary excavation levels; and are considered the remains of a single individual because of the rarity of the taxon, their similar size and taphonomic alteration, and the presence of paired elements. Radiocarbon dating of the macaw reveals it comes from the ninth millennium cal BP, the oldest date recorded from Nemocón IV. Paleoenvironmental data suggest that, during the deposition of the Preceramic levels at Nemocón IV, climatic conditions were close to those of today. The modern range of the macaws is outside these climatic parameters, and all modern Ara species are allochthonous to the Sabana de Bogotá, indicating the archaeological macaw was also allochthonous in Preceramic times. Analysis of the remains shows the macaw was not dismembered, so it is unlikely that it was used as food. Early conquest records indicate macaws were traded and maintained outside their natural ranges as pets, as a source of feathers, for use in rituals, or for a combination of uses.
