Woodland

The Land Stewardship Team at Trent University's Symons Campus conducted the initial mapping of vegetation units through aerial photo interpretation, followed by ground-truthing in the field to verify the type and extent of each community. Species identification and abundance estimates, ranging from dominant to rare (based on definitions from Lee et al., 1998), were performed across all four vegetation layers: canopy, subcanopy, shrub, and ground. This detailed botanical inventory enabled the assessment of botanical quality within the site. Smaller communities, typically less than 0.5 hectares, were delineated as distinct vegetation types where feasible, leveraging the improved resolution of aerial imagery and the smaller project scale. The practical applications of this detailed vegetation mapping include analyzing percent cover and habitat diversity, as well as identifying priority areas for preservation and restoration. Data collection was conducted in the field across various nature areas from 2021 to 2024, with additional gaps filled in 2025. North-south Environmental updated this layer in December 2025 using data from the Land Stewardship team. This data is used daily by the team during fieldwork and is updated every five years or as new habitats are restored or created. The ongoing use and periodic updates of this data ensure that the ecological integrity of the nature areas is maintained and enhanced, supporting informed decision-making for conservation and land management efforts. For more information, please refer to the Nature Area Management Plans, which contain classifications for each nature area as well as descriptions of the communities within them.
Invasive Vegetation Points and Management Strategies

Overview This feature service provides comprehensive spatial data on invasive vegetation within the Trent University Green Network, along with detailed records of management efforts aimed at controlling these species. The Land Stewardship Team at Trent University's Symons Campus has been collecting data on invasive species through both incidental and methodical surveys since 2022. Relevant Resources: [Nature Areas Management Plans] and [Ggwepnandizamin]. Feature Layers * Invasive Vegetation Areas: This layer maps the geographic locations of various invasive plant species found within the green network. It includes data on species type, abundance levels, community classifications, and size of affected areas. The layer also captures the collection methods used during surveys and identifies control constraints relevant to terrain or environmental conditions. * Invasive Vegetation Areas Management: This table documents management activities applied to invasive vegetation patches, detailing the management methods used such as herbicide application, pulling, and selective cutting. It also records the year when management took place and categorizes the invasive species being addressed. Geographic Coverage This service geographically focuses on the Trent University campus lands, providing targeted information for managing and monitoring invasive vegetation within this specific region.
Road Mortalities

The Land Stewardship team at Trent University's Symons Campus has been collecting road mortality data through surveys since 2022. These surveys are conducted from spring to fall by walking the roads and are supplemented with data from iNaturalist. The team gathers points and photographs along University-owned roads, including Woodland Road, Pioneer Road, Nassau Mills, and University Drive, with plans to potentially expand to other roads in the future. The goal of this data collection is to identify locations on roadways with high mortality rates (statistically significant hot spots) and to determine which species are affected. This information will help inform mitigation efforts.

Hydro Corridor

The hydrocorridor is based on the location of utility lines. Hydro One has control rights over the lands within the transmission corridor on the Symons Campus. This corridor contributes to Hydro One"s ability to deliver safe, reliable, and affordable electricity throughout the Province. Hydro One has the primary right to use the corridor lands for transmission and distribution purposes and hold a statutory easement under the Reliable Energy Consumer Protection Act. Hydro One offers a Provincial Secondary Land Use Program, which permits public use of the corridor in a manner that does not restrict the continued operation and maintenance of the Hydro Corridor. The proposed meadow-way in the Trent Lands and Nature Areas Plan is a compatible use, identified in Hydro One"s Provincial Secondary Land Use Program, and will require consultation with and approval from Hydro One.

Woodlands

The data presented here were generated from the TLNAP's Natural Heritage Report, which is no longer available online. The assessment of woodland significance was based on the 'Significant Woodland' criteria outlined in the Natural Heritage Resource Manual (NHRM) for the Natural Heritage Policies of the Provincial Policy Statement (PPS), 2005, Second Edition (MNRF 2010). Although this manual was prepared to support the 2005 PPS, it remains the key reference document for identifying significant features and guiding the identification of Natural Heritage Systems throughout the Province.

Ontario Hydro Network (OHN) - Watercourse

Watercourses are line features – natural or manmade – that represent the location of flowing surface water. *Due to limitations of the shapefile format, OHN Watercourse data can only be downloaded as a complete shapefile or file geodatabase.

Bathymetry, Line

Bathymetry line data was collected to assess fish habitat in Ontario. Spot depths (bathymetry points) were used to measure the depth contours, which function like isobars to show lines of constant depth. Their density and positional accuracies vary depending on the survey style and parameters. This data should never be used for navigation.

Wetland

Wetlands are lands that are seasonally or permanently flooded by shallow water, as well as lands where the water table is close to or at the surface. In either case, the presence of abundant water has caused the formation of hydric (moist) soils and has favoured the dominance of either hydrophytic (water-loving) or water tolerant plants. The term wetland is a general one and includes specific land types commonly called marshes, bogs, swamps and fens. Other terms sometimes used to describe wetlands include mires, sloughs and peatlands. Periodically soaked or wetlands being used for agricultural purposes that no longer exhibit wetland characteristics are not considered to be wetlands for the purposes of this definition. Wetland polygons are mapped independently from other hydrographic data classes and may overlap water bodies or other hydrographic data. Not all wetlands have been identified and mapped. Active maintenance is ongoing province-wide. Evaluators using the Ontario Wetland Evaluation System (OWES) will find additional guidance on the [Ontario Wetlands evaluation] page. For user friendly viewing of the wetland data, navigate to Ontario’s [Make a Natural Heritage Map] web application. This map application displays wetlands that have been evaluated using the Ontario Wetland Evaluation System as provincially significant or non-provincially significant. The application also displays wetlands that have not been evaluated but have been mapped using other procedures. *Note: Due to limitations of the shapefile format, Wetland data can only be downloaded in the file geodatabase format (.gbd).
