Municipio de Barra do Gar gas: 260 km along new road NNE of village of XAVANTINA. (' X*2 km due W of Royal Society- Royal Geographic Society Base Camp. Base Camp is at 12°51’S. 51°45’W.) Alt. ca. 450 m. Along path 200 m west of main road* 30 Sept 1968" (Area of 10 km radius around Base Camp is situated on crest of the Serra do Roncador, a gently-sloped divide between Xingu drainage (via Rio SuiS Migu) to west and Aragu&ia drainage (via Rio das Mortes) to east. The yet undissected few-km wide crest Is flat or gently rolling with a few low lateritic scarps and ridges. Brook valleys with very gentle to moderately steep slopes. Base Camp area is exactly at climatic boundary between Amazonian forest region and central Brazil “cerrado” region (savanna sens. lat.). North-western half of area is covered with the outer edge of the continuous Amazonian forest, here a slightly semide- ciduous dry mesophytic forest 15-18 m tall on the upland, taller along the seasonally dry brooks. Southeastern half of area has, on the upland, xeromorphlc semideciduous cerrado, in the form of medium-tall open scrub or tree-and-scrub woodland, with evergreen gallery forests 20-30 m tall along the permanent brooks. Usually a band of seasonally marshy grassy campo, a few meters to a few tens of meters wide, borders the gallery forests, separating them from the cerrado, but where the campo Is lacking, the cerrado grades directly Into gallery forest through a narrow band of its arboreal form, “cerradao”. The campos usually have scattered circular groves of cerrado scrub several meters in diameter on slightly raised soil, each with a termite mound. On the upland the cerrado region grades into the continuous dry forest region through a few-km wide ecotone of cerradSo. Underlying rock is various kinds of sandstone, giving rise to slightly clayey fine-sandy deep latosols, sterile and reddish or yellowish-tan with almost no humus on upland under cerrado, and dark red with more clay under dry forest. In restricted areas under cerrado, small laterite blocks or quartz pebbles may form a thin permeable subsurface layer, or the upper soil layer may be purely of laterite pebbles. Valley soils are deep light gray fine sand with little or no clay, sterile on drier upper slopes, black with humus in upper layer on moister or soaking lower slopes and floors. Shales underlie soils in a few valleys. At this date the Base Camp region has not yet been settled; the forests are virgin; the cerrado and campo are uncut and ungrazed, but have been subjected to ground fires set by Indians every 3-5 years. In the cerrado, these infrequent fires temporarily reduce density of the lower shrubs but otherwise have no effect on the physiognomy.) __ , , Habitat of this n.°: low-tree woodland cerrado* This n®: shrub.
