Expeditions by the Associação Floresta Protegida, the Kayapo NGO representing communities of the northeast, were land based and performed along the Linha Seca dry border (i.e. a border defined on a map and not by a river) (Table 2; Maps 8,9,10). The Linha Seca region is bordered by ranches that, given the chance, will encroach on Kayapo territory. Loggers can easily gain overland entry here as
well if not deterred. Therefore, locating and reclearing the demarcation line is important. Guards from the Xingu and Iriri posts do not need to patrol per se as both are the gatekeepers of northern access to their rivers, i.e. no unauthorized persons can get past these posts to start illegal activities inside the protected territory of the Kayapo conservation alliance. Nevertheless, guard team rotation between villages and the post plus some additional travel means that some 60 km of the Iriri river is monitored as far as the northern border. Also, travelling to and from the Riozinho and Rio Vermelho guard posts means that some 50 km of the Riozinho and 40 km of the Rio Vermelho is patrolled regularly.

Associação Floresta Protegida representing Kubenkranken organized an expedition of two weeks by 15 members of this community to patrol ~200 km of the Riozinho river from the village north to where the Riozinho river empties into the Fresco river. This expedition was especially arduous because it took place during the dry season when the water level in the Riozinho river is very low. The objective of the expedition was to check for any signs of invasion as indicated, for example, by muddy water from goldmining flowing into the Riozinho from feeder streams, and ii) generate income for the community. No signs of illegal activity were observed.
