Riparian ecotone from LiDAR

__The link: *Access the data repository* is available in the*Dataset Details; Additional Information*__ section. In 2020, the Directorate of Forest Inventories of the Ministry of Natural Resources and Forests (MRNF) began producing vector layers of riparian ecotones. This type of layer is produced using a series of geomatic tools that use the canopy height model (MHC) and the topographic humidity index (TWI) produced from aerial LiDAR, as well as data from the ecoforest map of southern Quebec. The development of the tools and their configuration were carried out in collaboration with the forest hydrology laboratory of Laval University. The layer thus produced aims to delimit riparian ecotones, which are defined as [_ “a transition zone between the aquatic environment and the forest, characterized by muscinal, herbaceous or shrubby vegetation in wetlands and sometimes including a few sparse trees” _] (https://mffp.gouv.qc.ca/RADF/guide/chapitre-i/article-1/). The layer produced delineates the area where a significant change in tree heights is observed on the MHC LiDAR. However, in the case where deforestation, an agricultural field, or a natural disturbance are adjacent to a body of water, no change in tree heights is observed. In these cases, the tool instead uses potential water accumulation data from the Topographic Humidity Index (TWI), as well as data from the ecoforest map, to delineate riparian ecotones. On the other hand, the tool does not allow all of these exceptional cases to be filtered and there are therefore some “false coastal ecotones” in the layer. For example, deforested land along a body of water may sometimes be included in the ecotone layer. Before using these data, it is therefore recommended to plan validation work by photo-interpretation or by means of field visits. It should also be noted that ecotone data is primarily used to support forest mandates such as the delineation of buffer zones along watercourses. They are therefore not wetland outlines within the meaning of the Act concerning the conservation of wetlands and bodies of water.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
