The Ecodistrict 6e10/St. Lawrence Islands Park GPE Vegetation Mapping Product
The Predictive Vegetation Modeling and Mapping Product for Ecodistrict 6E10 and St. Lawrence Islands Greater Park Ecosystem What is this product? This product is a digital atlas containing over 180 vegetation and habitat related maps generated through predictive modeling. The various maps contained in the atlas are raster grids1 with 10m pixel resolution. The digital atlas can be easily navigated through the use of various supporting documents and ‘readme’ files.
What is the extent of the Ecodistrict 6e10/St. Lawrence Islands Greater Park Ecosystem product? The mapping product covers all of Eco-district 6e10, plus the entire Greater Park Ecosystem (GPE) area of St Lawrence Islands National Park (Figure 1). The total area covered by this mapping product is 2467 km2.

With raster data models, the geographic area is divided into cells identified by row and column. This data structure is commonly called raster or grid.

Who produced the vegetation models and maps? The statistical modeling, validation, mapping, metadata and documentation for the Ecodistrict 6e10/St. Lawrence Islands GPE product were produced by the Information Management and Spatial Analysis (IM&SA) Unit, Southern Science and Information Section, Ontario Ministry of Natural Resources.
Why were the predicted vegetation maps for Ecodistrict 6e10/St. Lawrence Islands GPE created? In southern Ontario, there is a lack of current “wall-to wall�, fine-scale, detailed vegetation mapping that can support different applications and initiatives related to natural resource management, conservation and landscape and land-use planning. Wallto-wall products are those which comprehensively cover a project area (i.e. from one border to the other border). The Ecodistrict 6e10/St. Lawrence Islands GPE vegetation maps were created to serve as baseline information for resource management activities such as natural heritage design and planning, Species at Risk (SAR) recovery planning, state of biodiversity reporting, forest management and planning, invasive species management, ecological good and services estimates, wildlife habitat modeling and mapping and various additional applications and research techniques that require mapped vegetation information.
Figure 2. The Ecodistrict 6e10/St. Lawrence Islands GPE vegetation maps have been used to predict SAR habitat, including rock barren habitat suitable for the five lined skink. Dark green areas indicate higher probability of suitable habitat for five lined skink.

How were the maps for Eco-District 6e10 and St. Lawrence Islands GPE produced? Predictive Vegetation Modeling (PVM) was used to create these maps. PVM is a suite of statistical methods and processes that are used to develop models for species distribution and abundance and habitat characteristics based on data collected in the field and readily available mapped environmental information (e.g. Digital Elevation Models, soil information, climate averages), as well as information derived from satellite imagery. Once are developed and validated, the statistically-based models are extrapolated across the entire study area to map where a specific species is likely to occur and/or where it is likely to occur in greater abundance.
How was the field data that is used to support the modeling collected, and who collected it? Vegetation, soil and physiographical data were collected in the field following the Vegetation Sampling Protocol (VSP)2, which is a plot based sampling strategy. Field work was carried out and supported by St. Lawrence Islands National Park, Frontenac Arch and Charleston Lake Provincial Parks, Kemptville District OMNR and Eastern Ontario Model Forest. The IM&SA Unit provided the sampling methodology, the field sampling design and compiled, standardized and validated field information.
How long did it take to collect the field data that the maps are based on? Field data collection across Ecodistrict 6e10 and the St. Lawrence Islands GPE area took place over three field seasons, from 2005-2007 (Figure 3). During this time, over 1000 forest and 100 wetlands plots were visited in the field, and over 1000 rock-barren polygons were digitized. Spatial data preparation, statistical modeling, model validation, extrapolation and mapping were completed by the IM&SA Unit in late 2008.

How should this product be used? This product can be used to support various site specific or landscape scale applications and initiatives that require individual species, vegetation type, and forest structure and/or site characteristics maps. The maps contained in the product should be used with the understanding that individual maps are based on statistical models which have a known statistical uncertainty.
How were the models validated? All models were validated in a number of ways including internal model validation, withholding a portion of the data used in the modeling for validation, and validation with an independent data set. The results of the different validation methods are recorded for each vegetation model in the document “6e10_vegetationdigitalatlas.html” that is provided with the 6e10 and St. Lawrence Islands GPE products.

How is this product different from Forest Resources Inventory (FRI) mapping? The Ecodistrict 6e10/St. Lawrence Islands GPE and FRI mapping products differ fundamentally in how they were derived. While FRI mapping relies primarily on aerialphoto interpretation, the Ecodistrict 6e10/St. Lawrence Islands GPE maps are statistically derived and relied heavily on data collected in the field. FRI mapping provides a few structural and compositional variables (e.g. dominant tree species, tree height and age, site quality), while the Eco-district 6e10/ St. Lawrence Islands GPE mapping provides up to 180 variables as mapped products (e.g. dominant tree, shrub and ground vegetation distribution, percent canopy cover, forest structure, site characteristics). In addition, mapping for Ecodistrict 6e10/ St. Lawrence Islands GPE also includes mapping of nontreed wetlands (Figure #) and rock-barrens.
How does this product relate to Southern Ontario Land Resource Information System (SOLRIS) mapping? Forest vegetation for Ecodistrict 6e10/St. Lawrence Islands GPE was modeled and mapped within the 2000-02 SOLRIS boundaries (i.e. SOLRIS woodland and wetland polygons), and as such forest extent and minimum mapping units are inherited from SOLRIS. In contrast to SOLRIS, this mapping product has more classes for forests, wetlands and also includes rock-barren ecosystems.
What variables are mapped in this product? Variables mapped in the Ecodistrict 6e10/St. Lawrence Islands GPE product include structural vegetation characteristics such as canopy cover and basal area as well as species composition information for dominant canopy and ground species, both presence and abundance. Various vegetation classes were mapped, including statistically derived species assemblages (Figure 4) and ELC Vegetation Types. Wetland classes, rock barrens, and soil moisture were also predicted and mapped.
