“…Second, non-destructive harvest must be encouraged, by promoting the use of basic techniques for climbing (Borgtoft Pedersen, 1992;Zent & Zent, 2002;Weinstein & Moegenburg, 2004) or different type of tools (Holm Jensen & Balslev, 1995;Vormisto, 2002;Fadiman, 2003;Torres, 2007;Linares et al, 2008). Finally, palm species of interest should be introduced in agroforestry systems, which seems to be an adequate alternative for sustainable management; these practices are documented for at least 15 palms in South America, including Bactris gasipaes (Clement, 1986(Clement, , 1989, Attalea speciosa (May et al, 1985b), and Ceroxylon echinulatum (Pintaud & Anthelme, 2008).…”

“…), and palm wine from Jubaea chilensis (González et al, 2009). Other palm products are harvested from isolated palm individuals surviving in pastures or other deforested areas; examples of these include leaf sheath fibers from Aphandra natalia in Ecuador (Borgtoft Pedersen, 1992), leaf fibers from Astrocaryum malybo, fruits from Attalea butyracea, Ceroxylon spp., and Copernicia tectorum in Colombia (Galeano & Bernal, 2005; Barrera et al, 2007a, b;Bernal et al, 2010), fruits from Attalea speciosa and A. phalerata in Brazil (May, 1991;Pinheiro, 2004), palm sap from Jubaea chilensis in Chile (González et al, 2009), and leaves and fruits from Butia capitata in Uruguay (Pezzani, 2007). Some palms are planted in fallows or they are selectively favored when the forest is cleared for swidden-fallow agriculture.…”

“…Removal of neighboring plants is often used as a practice to favor development of seedlings or juveniles of useful species Velásquez, 1998;Brondízio et al, 2002;Johnson, 2002;Meza, 2001). In some cases, as in the management of fruit producing Attalea maripa, A. speciosa and Oenocarpus bacaba, unproductive palms are eliminated, in order to open space for new individuals (May et al, 1985a;Zent & Zent, 2002). In the dioecious Mauritia flexuosa and Phytelephas aequatorialis, new space in the palm stands is gained by reducing the number of male palms Velásquez, 1998).…”

We reviewed information on management of useful palms in South America. We documented management for 96 species, from incidental activities intended to increase populations of wild palms to the inclusion of palms in complex agroforestry systems. Two species, Bactris gasipaes and Parajubaea cocoides, are domesticated. Managed species are remarkably fewer than species used in the region, which suggests that harvesters often disregard the fate of the species they use. The best way of managing palms is to employ harvest methods that do not decimate the populations. Although a variety of harvesting techniques have been documented, overharvest is common, and mismanagement prevails -unnecessary felling of palms in order to harvest leaves or fruits is a widespread practice. Research should focus on assessing production in response to management practices, but eradicating the habit of destructive harvest is an obvious priority. Research on palm management must be combined with actions addressed to all stakeholders of the palm/humans system.Resumen Revisamos la información sobre manejo de palmas útiles en Suramérica. Documentamos manejo para 96 especies, desde el cuidado ocasional de palmas con el fin de incrementar las poblaciones silvestres, hasta la introducción intencional de algunas especies en chagras o en sistemas agroforestales. Dos especies, Bactris gasipaes y Parajubaea cocoides, son domesticadas. Las especies manejadas son notablemente menos que las especies útiles, lo que refleja poco interés de los cosechadores por la suerte de las especies usadas. La mejor forma de manejar las palmas es emplear métodos de cosecha que no diezmen las poblaciones. Aunque se han documentado diversas técnicas de cosecha, la sobrecosecha es común y predomina el mal manejo: tumbar innecesariamente las palmas para cosechar las hojas o los frutos es una práctica común. La investigación debería enfocarse en evaluar la respuesta de las palmas a las prácticas de manejo, pero es prioritario erradicar las prácticas de cosecha destructiva. Se debe combinar la investigación sobre manejo de palmas con acciones dirigidas a todos los actores del sistema palma/hombre.

Much of deforested Amazonia is dominated by pastures planted with exotic Urochloa (syn Brachiaria) grass, containing interspersed, ruderal Babassu palm (Attalea speciosa). This two‐species system offers the opportunity to investigate how two very competitive species interact. We investigated three monospecific Urochloa pastures containing dispersed Babassu palm clusters in the eastern periphery of Amazonia. We mapped 0‐ to 50‐cm Babassu and Urochloa root profiles at three distances representing contrasting relative dominance: “within clusters” (0.4–0.6 m from adult palm, Babassu‐dominated), “close” (2.5–4.0 m), and “far” (>8.0–10.0 m, Urochloa‐dominated). Total Babassu root share count was 76.0% within Babassu clusters, as opposed to Urochloa root share count (80.0%) far from clusters, confirming our experimental dominance gradient. Babassu and Urochloa root diameter composition differed strongly, whereas 44.6% of all Babassu roots were mid‐diameter or coarse; 83.0% of all Urochloa roots were fine graminoid. Vertical root profiles likewise differed: Babassu coarse and mid‐diameter roots concentrated within clusters at 20–50 cm depth, well protected against disturbance, though Babassu mid‐diameter roots did extend up to 10 m, indicating active foraging at long distances. By contrast, Urochloa mid‐diameter and coarse roots concentrated in the topsoil (70.4% in top 20 cm). Notably, 45.0% of all Urochloa fine roots but only 29.3% of deeper rooting Babassu concentrated in the top 0–10 cm. Both Urochloa mid‐diameter (R = 0.49) and fine roots (R = 0.40) correlated positively with Urochloa aboveground biomass. Fine‐root fine‐scale variability was high, with high‐density hotspots of both species in the topsoil. Babassu vertical root profiles were unaffected by the degree of interspecific competitive confrontation, whereas Urochloa fine roots were significantly shallower within than outside of Babassu clusters. Though differing Babassu and Urochloa vertical root profiles do support the notion of niche expansion caused by Babassu clusters within the vast Urochloa pastures throughout Amazonia, we also find a strong horizontal and vertical niche overlap with no indication of fine‐scale root segregation, indicating direct competition between both species, possibly in a dynamic state of “mutual invasability.” In practical terms, our findings call for the diversification of Amazonian pastures beyond this two‐species system in order to increase productivity and ecological efficiency.
