“…The community structure is mainly characterized by the species Tetragastris panamensis and Astrocaryum gynacanthum, with the second and third highest importance value (IV), but with higher density and absolute and relative frequency. The T. panamensis was also found in clayey soils in Peruvian, Venezuelan and Colombian Amazon, and also in State of Acre in Brazil (Duque and Cavelier 2003, Trivede et al 2004, Fine et al 2005, Rockwell et al 2007, Lozada et al 2014, showing a widespread distribution in Amazon forest. The same occurs with A. gynacanthum with distribution throughout the Amazon basin and the Guianas, found in Bolivia, Brazil (Acre, Amapá, Amazonas, Pará, Rondônia, Roraima), Colombia, French Guiana, Guyana, Peru, Suriname, Venezuela (Kahn 2008).…”

Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were installed for floristic and phytosociological surveys as well as to collect composite soil samples. The data were subjected to assessments of floristic diversity and similarity, phytosociological parameters and to statistical analyses, focused on principal components (PC) and canonical correspondence analysis (CCA). The vegetation of the Campinaranas types and Forest differed in biomass and species density. Ten species, endemic to Brazil, were particularly well-represented. PC and CCA indicated a clear distinction between the studied plots, based on measured soil variables, especially base sum and clay, which were the most differentiating properties between Campinarana and Forest; For the separation of the Campinarana types, the main distinguishing variable was organic matter content and cation exchange capacity. Higher similarity of Campinaranas was associated to a monodominant species and the lower similarity of Forest was related to the high occurrence of locally rare species.

“…Sin embargo, si se incrementara la intensidad y escala, tendrían que revisar los criterios de aprovechamiento y considerar actividades orientadas a promover la regeneración natural de las especies aprovechadas. Dos problemas serios de los inventarios convencionales en los bosques tropicales húmedos son la identificación correcta de las especies -sobre todo en áreas pequeñas y para especies que ocurren en manchas -y la cantidad de mediciones necesarias para tener una muestra representativa del bosque (Rockwell et al 2007a). La contribución de los pobladores locales es clave para la identificación de las especies, ya que su conocimiento es mejor que el que suelen tener los técnicos o profesionales forestales…”

“…Esta práctica se aplica en la comunidad de Cachoeira, estado de Acre, Brasil (Recuadro 2-3), y más recientemente en el sistema de aprovechamiento de la palma chunga (Astrocaryum standleranuma) usada para la producción de artesanías en el Darién panameño. Rockwell et al (2007a) sugieren que estos sistemas deberían ser aplicados en todo el bosque manejado y no solo en el área de aprovechamiento anual. Aunque parezca prometedor, aún hace falta validar el sistema en otras comunidades y tipos de bosques.…”

“…Small-scale forestry commonly refers to "non-industrial private forests" (NIPFs) or smallholder forestry [4][5][6], with ownership usually by individuals who may have multiple objectives beyond timber production and who do not own a wood-processing facility [7]. Threshold limits that can range from 500 ha for smallholder tropical forestry in Brazil to 200 ha in Germany and as little as 3 ha in Italy and Spain have been suggested, while the average size of "family forests" in the US is 25 acres [2,6,8].…”

Abstract:Horse skidding for extracting logwood is characterized as a niche activity in small-scale forestry, limited to small tracts and low volumes, where environmental impacts and aesthetics are concerned, and to operations with no wood-processing facilities. This article documents and analyzes the widespread persistence, current magnitude, and multiple advantages of horse skidding in large-scale industrial community forest enterprises in Chihuahua, Mexico. We extracted data from the logging permit files of 59 communities in the Sierra Tarahumara and conducted semi-structured interviews with community leaders and foresters in 18 communities, 17 random selections, and one purposefully selected case. There are nine communities that can be considered large-scale. Six of them use animal traction for 20%-100% of their volume. All have sawmills integrated with their operations. This includes the El Largo community with a ten-year volume of 3,169,019 m 3 extracted from 123,810 ha entirely with horses. Respondents to the interviews report that horse skidding is more cost-effective than mechanized skidding, generates more employment, and has less impact on forests due to reduced carbon emissions. The widespread use of animal traction in large-scale industrial community forestry in Chihuahua demonstrates that horse skidding is not only a niche activity in small-scale forestry. Our data is preliminary, but we suggest that it highlights a need for further assessments of whether animal traction should be part of future efforts towards reduced impact, lower carbon emissions, and socially and economically just forest management.
