MIGUEZ G., Sofia; PANIAGUA-ZAMBRANA, Narel  and  MORAES R., Mónica. Population state, use and marketing chain of the Ramo Palm (Ceroxylon pityrophyllum), Arecaceae. Ecología en Bolivia [online]. 2020, vol.55, n.2, pp.127-139. ISSN 1605-2528.

The use of Ceroxylon pityrophyllum or "Ramo palm" in Bolivia is the weaving of leaves during "Palm Sunday"; because it is a seasonal activity, distribution and harvesting categories are unknown. The objective of the work was to evaluate the population structure, regeneration, density and spatial distribution of individuals, as well interpret the marketing chain in the city of La Paz. The field work was carried out between 2018-2019 in traditional harvesting sites (Saukela, La Plazuela and Sapacani) in Lambate (Sud Yungas, Irupana province). To evaluate the population structure and spatial distribution the plot-variance method was used in 30 plots of 10 x 10 m with records of total height, DAP, number of leaves, pinnae and reproductive structures per individual. Semi-structured interviews were conducted with 60 sellers in 18 churches in order to record information about used palm species, their procedence, purchase-sale prices and types of fabric they make. 540 individuals were counted in five growth categories: seedlings (158), juveniles 1 (114), juveniles 2 (93), pre-adults (153) and adults (22), with a type 2 population curve. It shows a pattern spatial aggregate in the three evaluated sites. Four stages in the commercialization chain were identified: a) Access and selection of the leaves, b) Collection and transport and of the leaves, c) Artisan transformation and d) Sale; and, six links: 1) forest supplier, 2) harvester, 3) transponer, 4) intermediary sellers, 5) sellers in the churches, and 6) buyer or consumer. This information will serve as a basis to guide the proper harvesting of leaves in management plans and to guide their commercialization.
