与原住民热带森林管理区域中物证链相关的测量程序

[中文适用范围]： 本文件建立了一个过程，用于测量在经批准的记录计划下对原生热带森林管理区域进行采伐的木材。该过程包括量化和监测采伐面积，以支持所有权链评估，帮助确保采伐木材的来源。本文件不包括木材体积测量。本文件提出了可用于加强信心水平的指标，特别是在评估木材产品的运输和商业文件时，通过与在原生的热带木材声明来源地森林区域中观察到的情况进行一致性检查。这些指标将作为检测到的任何潜在不一致性的警报。这些指标是通过标准化指标获得的。这些指标是数学模型，它们建立通过遥感监测工具检测到的植被削减面积与产生的声明采伐木材数量的采伐树木数量之间的相关性。本文件旨在用于量化世界各个热带森林区域通过选择性采伐原生植被提取所产生的影响，以支持这些森林资产的长期维护。本文件的范围限于原生热带森林，即热带地区由原生树种（或类群）自然起源和形成、并显示自然动态、枯木发生、复杂年龄结构和自然再生过程的森林。本文件不适用于人工林，无论树种（或类群）是原生还是外来，因为这些森林受到各种特殊管理实践的约束，具体取决于其所在地理位置和所在国家的规则。关于本文件的局限性，它不旨在确保：——每根木材的确切来源（地理坐标）；——从森林中提取的木材的确切体积；——采伐木材的树种（或类群）；——所有权链的合规性；——被审计操作的社会和劳工合规性；——被审计操作的税务合规性。本文件不侧重于生物质和碳平衡估算，也不面向该领域。本文件不涵盖可持续森林管理方面的任何内容，仅侧重于上述测量程序。此外，它不旨在成为管理体系标准（MSS）。此外，本文件不重复国家法律要求和国际政策，包括与可持续性方面以及与原住民和土著社区相关的原则/条款，这些原则/条款包含在《联合国土著人民权利宣言》（UNDRIP）中。 [外文原描述]： This document establishes a process to measure wood being logged in native tropical forest management areas following an approved and documented plan. Such a process includes quantifying and monitoring the harvested area to support the chain of custody assessment, helping to ensure the origin of the logged wood. Wood volume measurement is outside the scope of this document. This document proposes indicators that can be used to reinforce the level of confidence with regards to the correct origin of the logged wood, particularly when assessing the transport and commercial documentation of wood-based products, by means of a consistency check with what can be observed as occurring in the forest area declared as the origin of native tropical timber. The indicators will serve as an alert of any eventual inconsistency detected. These indicators are obtained by means of standardized metrics. These metrics are mathematical models that establish a correlation between the area of subtracted vegetation – detected through remote sensing monitoring tools – and the number of extracted trees that generate the amount of declared logged wood. This document is intended to be used to quantify the impact resulting from native vegetation extraction by selective logging in various tropical forest regions of the world, in order to support the long-term maintenance of these forest assets. The scope of this document is limited to native tropical forests, i.e. forests naturally originated and formed by native species (or group) in tropical regions. This document does not apply to planted forests, regardless of the species (or group) being native or exotic, as those forests are subject to varied and particular management practices which depend on the geographical conditions and rules of the country in which they are located. Regarding the limitations of this document, it is not intended to ensure: exact origin (geographical coordinates) of each log; exact volumes of wood extracted from the forest; species (or group) of wood harvested; chain of custody compliance; social and labour compliance of the audited operation; tax compliance of the audited operation. This document does not focus on, and is not oriented towards, biomass and carbon-balance estimations. This document does not cover any aspects of sustainable forest management and focuses on measurement procedures described above. In addition, it is not intended to be a Management Systems Standard (MSS). Furthermore, the national legal requirements and international policies are not repeated in this document, including those related to sustainability aspects, as well as those related to traditional and indigenous communities contained in the principles/articles of the UN Declaration on the rights of Indigenous Peoples (UNDRIP).
