According to L.211-1 of the Environmental Code, I. — 1° [...] Wetland means land, whether or not operated, usually flooded or engrown with fresh water, salted or brackish on a permanent or temporary basis; vegetation, where it exists, is dominated by hygrophilic plants for at least part of the year; [...] Article R.211-108 of the same code states: • the criteria to be used relate to soil morphology linked to the prolonged presence of original water natural and possible presence of hygrophilic plants, • in the absence of hygrophilic vegetation, soil morphology is sufficient to define a wetland, • the delimitation of wetlands is carried out using flood or groundwater levels, or tidal frequencies and amplitudes. Field diagnostics refer to areas with hydrological criteria (flooding or frequent waterlogging) and/or soil (soil showing a water-saturated environment) and/or botanical (vegetation dominated by hygrophilic plants) of wetlands. They always use field surveys to justify the verification of these criteria. These areas are more specific than wetlands, but are not always exhaustive. Indeed, depending on the methodology used (flora and/or pedology), some wetlands may not be identified. When actual wetlands are demarcated according to the definition of the Environmental Code and on the basis of the criteria detailed in the Order of 24 June 2008 as amended on 1 October 2009, then it is referred to as regulatory delimitation or “water policy” wetlands. These areas are defined if the soil and flora criteria are verified, except where the vegetation present is not “spontaneous”. In this case, the soil criterion alone is sufficient to determine the wetland (see Technical Note of 26 June 2017 on the characterisation of wetlands — in particular for the definition of “spontaneous” vegetation). In the case of a project, it is up to the petitioner to prove that his project is not wetland or, if not, to delimit them by regulation. Maps of predominantly wetlands available on the project’s right-of-way are not sufficient to prove the absence of wetlands.根据《环境法典》第L.211-1条第一款——1°[...]湿地（wetland）指无论是否经开发利用，通常被淡水、盐水或咸淡水永久或临时淹没或浸润的土地；若存在植被，则在一年中至少一段时间内以湿生植物（hygrophilic plants）为优势群落[...]。同法典第R.211-108条规定：• 判定标准需关联长期天然原生水体存在相关的土壤形态，以及湿生植物的自然存在情况；• 若无湿生植被，仅凭土壤形态即可认定为湿地；• 湿地划界可依据洪水水位、地下水位，或潮汐频率与振幅开展。现场诊断（field diagnostics）指符合湿地水文标准（被淹没或频繁积水）和/或土壤标准（土壤处于水饱和环境）和/或植物学标准（植被以湿生植物为优势群落）的区域。此类区域均需通过实地勘测验证上述判定标准。这类区域的范围较湿地更为具体，但并非涵盖所有湿地。实际上，依据所采用的勘测方法（植物学和/或土壤学），部分湿地可能无法被识别。当依据《环境法典》的定义，并参照2008年6月24日经2009年10月1日修订的政令中详述的标准划定实际湿地时，即称为法定划界湿地或“水政策”（water policy）湿地。此类区域的认定需满足土壤与植物学标准，但若现有植被并非“自然原生”（spontaneous），则仅需土壤标准即可判定为湿地（详见2017年6月26日发布的《湿地特征界定技术说明》——尤其针对“自然原生”植被的定义）。针对项目场景，应由申请人证明其项目不涉及湿地；若涉及湿地，则需通过法定程序划定湿地范围。项目用地范围内现有的主要湿地地图，不足以证明该区域不存在湿地。
