可再生自然资源的管理和相应的政策制定应建立在可靠的数据和信息基础上。这既指关于资源本身的信息，也指关于市场情况的信息。在本文中，我们提出的方法和主要结果的瓜杜瓦资源的库存，在一个研究领域内的咖啡区哥伦比亚约100万公顷。这份清单首次对瓜杜瓦的面积和不断增长的种群进行了抽样统计估计。在研究区域，Guadua斑块的土地覆盖率估计为3.9%，约为40，000公顷（最小斑块面积为0.3公顷）。这个数字高于早些时候公布的数字。每公顷平均立竹（包括嫩枝和干竹）数量估计为6，940根，平均胸径为10.8厘米，表观商业体积为654立方米/公顷，商业木材体积为304立方米/公顷，烘干生物量为311吨/公顷，总碳储量为156吨/公顷。虽然低强度采样方法效果良好，可以作为类似研究的一个例子，但我们确定了一些需要进一步研究的问题，特别是在从清单中估计瓜杜瓦体积和生物量的基本测量模型方面。
Management of renewable natural resources and the corresponding policy formulation should be founded on reliable data and information. This refers both to information on the resource itself and to information on the market situation. In this paper, we present methodology and major results of an inventory of the Guadua resources, in a study area of about 1 million ha within the Coffee Region of Colombia. This inventory produced for the first time sample-based statistical estimations of the Guadua area and growing stock. In the study area, land cover of Guadua patches was estimated to be 3.9% or about 40,000 ha (minimum patch area 0.3 ha). This is higher than figures published earlier. Estimation for mean number of standing culms (including shoots and dry culms) per hectare was 6,940 with a mean diameter at breast height of 10.8 cm, apparent commercial volume of 654 m(3)/ha, commercial wood volume of 304 m(3)/ha, oven-dry biomass of 311 ton/ha, and total carbon stock of 156 ton/ha. While the low-intensity sampling approach worked well and may serve as an example for similar studies, we identified a number of issues for further research, particularly in what refers to as the basic mensurational models for Guadua volume and biomass estimation from inventories.
