Researchers have argued that indigenous peoples preferably use the most apparent plant species, particularly for medicinal uses. However, the association between the ecological importance of a species and its usefulness remains unclear. In this paper we quantify such association for six use categories (firewood, construction, materials, food, medicines and other uses). We collected data on the uses of 58 tree species, as reported by 93 informants in 22 villages in the Tsimane' territory (Bolivian Amazon). We calculated the ecological importance of the same species by deriving their importance value index (IVI) in 48 0.1-ha old-growth forest plots. Matching both data sets, we found a positive relation between the IVI of a species and its overall use value (UV) as well as with its UV for construction and materials. We found a negative relation between IVI and UV for species that were reportedly used for medicine and food uses, and no clear pattern for the other categories. We hypothesize that species used for construction or crafting purposes because of their physical properties are more easily substitutable than species used for medicinal or edible purposes because of their chemical properties.
研究人员认为，原住民更倾向于使用最显眼的植物物种，尤其是用于药用。然而，一个物种的生态重要性与其有用性之间的关联仍不明确。在本文中，我们对六个用途类别（柴火、建筑、材料、食物、药物及其他用途）的这种关联进行了量化。我们收集了93位信息提供者报告的关于在齐曼内地区（玻利维亚亚马逊地区）22个村庄中58种树木的用途数据。我们通过计算这些物种在48个0.1公顷的原始森林样地中的重要值指数（IVI）来得出它们的生态重要性。将这两个数据集进行匹配后，我们发现一个物种的IVI与其总体使用价值（UV）以及其在建筑和材料方面的UV之间存在正相关关系。我们发现，据报告用于医药和食物用途的物种的IVI与UV之间存在负相关关系，而其他类别则没有明显的模式。我们推测，由于其物理特性而用于建筑或工艺目的的物种比由于其化学特性而用于药用或食用目的的物种更容易被替代。
