The traditional traps used for harvesting the species--known locally as 'matapis'--are hand-made from strips of stems of spiny (Astrocaryum spp.) or
piassava (Raphia vinifer) palms (Figure 1).
She said the country is rich in iron ore, diamonds, gold, silver, bauxite, timber,

gasipaes and, to a lesser extent, Mauritia flexuosa from Peru (Rios, 2001; SUNAT, 2006);
piassava fibers of Attalea funifera from Brazil (Voeks, 1988), and those of Leopoldinia piassaba from Colombia and Brazil (Centro de Comercio Internacional, 1969; Crizon, 2001; Linares et al., 2008), both of which were an important export product in the 19th century (Wallace, 1853); thatch tiles woven with leaves of Geonoma deversa from Bolivia (L.
(2005) found that the flexural strength of
piassava fiber-reinforced orthophtalic polyester composite (40% [wt/wt] fiber loading) was independent of a molding pressure below 9.2 MPa.
It was particularly well known for the trade of palm nuts and
piassava, a palm fibre used to make brooms in the traditional way.
Leopoldinia piassaba (
piassava in Brazil, chiquichiqui in Colombia and Venezuela, fibra in Colombia) is distributed in the upper Rio Negro region of Brazil, Colombia and Venezuela (Figure 1), especially on poor and sandy soils associated with black water rivers where it forms extensive single-species patches covering several hectares.
Within cabruca, polyculture is trickier because there's less light to work with, but it should be feasible to include various other shade tolerant crops, such as the fruit- and fiber-producing palms, acai (Euterpe oleracea) and
piassava (Attalea funifera).
