Forest biomass and carbon in southern Quebec

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


The Directorate of Forest Inventories (DIF) carries out assessments of tree biomass and their carbon content at the scale of ecoforest stands to deepen knowledge on the contribution of forests in the global carbon cycle. This information can be useful in the context of climate change to document the mitigating role played by forests.

The resulting product, a database containing a single table entitled “BIOMASSE_CARBONE_PEE_ORI_PROV”, shows the biomass and carbon values of living trees above ground for all productive ecoforest stands 7 m or more in height.

The exploitation of the database requires the data from [the original ecoforest map] (https://www.donneesquebec.ca/recherche/dataset/resultats-d-inventaire-et-carte-ecoforestiere) and the establishment of a connection with the information of the polygonal entity class of settlements.

The database includes biomass variables converted to carbon stocks, detailing the biomass of wood, bark, branches, and foliage. For a thorough understanding, you can consult the Read Me associated with this product and the publication [“Biomass and carbon forests in southern Quebec - Method and use”] (https://mrnf.gouv.qc.ca/nos-publications/biomasse-carbone-forestiers-quebec-meridional/) (MRNF, 2023) which offers additional methodological information.

Water levels during a flood (since 2017)

The Department of Homeland Security (MSI) supports the development of flood risk knowledge. In collaboration with Laval University and the Reunification of Quebec Basin Organizations, the MSI has developed a methodical and rigorous process for documenting floods that have an impact on the safety of people and essential goods.

Thus, since 2017, the Ministry of Homeland Security (MSI) has been acquiring in certain cases data related to the water level reached when floods with proven consequences occur in southern Quebec. Maximum water levels are indicated by flood overflows.

__What is a flood disaster? __

A flood (flood) is characterized by a rise in water on land that is usually dry, the reaching of a peak, then a descent of water (decline). Waste forms at the beginning of the flood when the water, when withdrawing, deposits materials that were in suspension or floating. These materials (mud, seeds, twigs and other debris) constitute flood wastes or flood plains.

__Marking and surveying flood plains and water levels__

The marking of floodplains and water levels takes place on the ground shortly after the peak of the flood. The physical indices of the maximum water level reached (abandoned by the flood) or of the current water levels are identified and marked using permanent markers (markers). Afterwards, a land surveyor will precisely record the location and the altitude of the markers. 

__Point dataset “Water levels during a flood"__

The “Water levels during a flood” data set contains, for each marker, the date, altitude and location (measured by a land surveyor). There are two main types of observations made in the field: the natural flood defect (line of mud, seeds or trace of water) which indicates the maximum water level reached during the flood (called MAX) and the water level observed during the field visit (called CURRENT). The list of all attributes is provided in the dataset description sheet (Additional Information section).

Despite the quality of the work carried out, the Ministry of Homeland Security cannot guarantee the absence of errors in the data.

__Related datasets__ 

The “Flood Benchmarks” dataset produced by the Ministry of Homeland Security also contains maximum water levels reached during a flood. The link to this dataset is provided in the _Documentation_ section.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Original ecoforest map and results of the fourth inventory

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


The original ecoforest map and the results of the 4th ecoforest inventory of southern Quebec constitute a grouping of ecoforest data including the original ecoforest map of the 4th inventory and numerous other tables providing information directly related to ecoforest populations. The information in this dataset corresponds to the forest profile up to the year of aerial photography. 
 
Among the numerous tables and entity classes that the product brings together, the following groups can be distinguished: 

* The original ecoforest map of the 4th inventory made up of ecoforest polygons. This is the geographic base to which all other data is attached; 

* The forest compilations of the 4th inventory, which contain, among other things, the gross commercial volumes evaluated by essence; 

* The ecological classification of Quebec territory; 

* Data for the characterization of forest stations. 
 

__Note that__ the original ecoforest map of the 4th inventory has been complete since 2018 and that no new mapping has been added. This differs from the current original ecoforest map where, each year, a portion of Quebec's territory is photo-interpreted and integrated into the provincial product by replacing the cartographic information from the previous inventory. In addition, some areas have not been mapped since the 3rd inventory and are therefore absent from the original ecoforest map from the 4th inventory.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Epidemic, windfall and ice

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


The mapping of **insect epidemics, shelters** (trees knocked down by the wind) ** and icecry** is produced as part of the ecoforestry inventory of southern Quebec in order to maintain an up-to-date portrait of the forest. It covers the commercial territory of public and private forests in Quebec. The minimum mapping area is 0.1 ha. This portrait is useful, among other things, for evaluating the intensity and extent of damage associated with insects, windfalls and ice. In each case, the mapping represents the loss of forest cover in the form of disturbances ranging from severe (over 75% of dead trees) to slight disturbances (from 25 to 75% of dead trees). 

The disturbances in this map date back to the beginning of the century (when information is available) to the present day. They are the result of collaboration between the Directorate of Forest Protection and the Directorate of Forest Inventories. The outlines come from forest inventories (first and second decennial inventories) and ecoforestry inventories (third and fourth decennial inventories). Mortality is dated using defoliation layers from the Directorate for Forest Protection. For the epidemic of TBE (spruce budworm), mortality is considered to occur after a succession of five years or more of severe or moderate defoliation. In the case of the surveyor, a single year is enough to decimate a forest stand. The other elements in the layer are dated using LANDSAT imagery, sample plots, and archival documents.

Grid of possible presence of a flood zone (data relating to old generation maps)

The standardized grid identifies sectors for which information on flood zones is available (old-generation maps, flood ratings, etc.). **Contact [the municipality or the MRC] (https://www.quebec.ca/gouvernement/portrait-quebec/repertoire-municipalites) () to check if flood zone boundaries have been established on old-generation maps for a property **.

The information disseminated in this grid comes from the following three sources of information (work has been done on the data to standardize everything):

* __ [Territory flooded in 2017 and 2019] (https://www.donneesquebec.ca/recherche/dataset/territoire-inonde-en-2017-et-2019)__

* __ [2017-2019 Special Intervention Zone (from which territories covered by a ministerial decree are excluded)] (https://www.donneesquebec.ca/recherche/dataset/delimitation-du-perimetre-de-la-zone-d-intervention-speciale-zis-annexe2-modifie)__

Change in forest cover detected by satellite imagery

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


**Change in forest cover detected by satellite imagery** is a provincial polygonal vector database produced using automated analysis of Sentinel-2 satellite imagery. This analysis aims to detect changes in forest cover throughout southern Quebec. 

The database includes disturbances of anthropogenic or natural origin, identified from images acquired during the summer period and analyzed at a resolution of 10 m × 10 m. It only contains detectable disturbances for which **no official information** was available at the time of the analysis. To determine if a disturbance is already known, the analysis compares the detected changes to the following official databases:

+ Harvesting and other silvicultural interventions
+ Forest fires
+ Epidemic, wind and ice storm
+ Forest infrastructures 

Polygons remain in the product as long as no official source confirms the nature or origin of the disturbance. As soon as official information becomes available, the element is removed from the diaper during the next release of the product. 

The analysis of the detected change is carried out once a year, during the months of October and November, using Sentinel-2 satellite imagery captured between June and September.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Flow/level stations - General public

Measurement of flow and level stations from partners of the Ministry of Public Security (MSP). The flows and levels make it possible to automatically monitor the risks of flooding in open water on rivers, watersheds and lakes where hydrometric stations are installed based on pre-established consequence thresholds. Other watercourses that do not have such instruments are also monitored by municipal and governmental authorities.

Data from the following partners are integrated into the application and web services: Quebec Water Expertise Center, Quebec Water Expertise Center, Meteorological Service of Canada, Hydrographic Service of Canada, Hydro Meteo, Chaudière River Monitoring System, USGS...
The latest level (m) and flow (m³/s) values are provided, when available, as well as the status of the station according to pre-established flood thresholds. The definition of states can be found here: https://vigilance.geo.msp.gouv.qc.ca/en-savoir-plus/stations#etat).


This data is updated several times a day and is also visualized in the Vigilance - Flood Monitoring application.

Up-to-date ecoforest map

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


The **up-to-date ecoforest map (formerly “with disturbances”) ** is the result of the interpretation of aerial photographs and control points in the field as part of the ecoforest inventory of southern Quebec.

This mapping presents the various forest and ecological characteristics of the forest territory and corresponds to the portrait of the forest up to the year in which the aerial photograph was taken (mapping cycle of about 10 years). Next, the outlines and nature of recent disturbances (forest interventions, fires and other disturbances) are then integrated annually. The fifth mapping cycle has been under way since 2015.

This map covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest. It is distributed by map sheet at a scale of 1/250,000. The minimum mapping area is 4 ha for stands and 0.1 ha for disturbances.

__ ⚠️ 1) Note that__ the disturbance maps used to update the updated ecoforest map are also distributed separately on Data Quebec. Here is the list of these maps:

+ ** [Forest fires] (https://www.donneesquebec.ca/recherche/dataset/feux-de-foret) **

+ ** [Harvesting and other silvicultural interventions] (https://www.donneesquebec.ca/recherche/dataset/recolte-et-reboisement) **


+ ** [Epidemics, windfalls and ice storms] (https://www.donneesquebec.ca/recherche/dataset/epidemies-chablis-et-verglas) **


+ ** [Forest Infrastructure] (https://www.donneesquebec.ca/recherche/dataset/infrastructures-en-milieu-forestier) **

__ ⚠️ 2) Note that__ disturbances are prioritized according to the nature of the layer and respect for the chronology of events. Only the last original or partial disturbance is kept in the updated ecoforest map. You should refer to the annual update layers, listed in __Note 1__, to have access to the full history of disturbances.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Flooded areas beyond established mapping

During flooding episodes, areas may be flooded even though the cartography established does not indicate that they are located in flood zones. This situation can occur when the water levels reached exceed those represented on the map or when floods affect areas that have not yet been studied. These cartographic data correspond to the delimitation of these territories and are used to produce event maps of these floods.

__To date, the following sectors have been maped:__

* Lac-Saint-Jean (2022)
* Saint-Maurice River (2022)

Photogrammetric capture, allowing the delimitation of these territories, was carried out following the farthest limit reached by the waters from aerial photographs taken during the floods. 
It should be noted that this work is part of measure 4 of __ [Plan for the protection of the territory against floods (PPTFI)] (https://www.quebec.ca/gouvernement/politiques-orientations/plan-de-protection-du-territoire-face-aux-inondations)__.
