"Ecoregions of Ontario is a synthesis, and integration of a wide range of environmental information for Ontario within the national ecological data base framework developed by the Canada Committee on Ecological Land Classification since 1976. The text of this report presents synthesized descriptions of the ecoregions of Ontario"--Preface.

Ecoregionalization systems used in resource management stratify terrestrial or aquatic ecosystems and attempt to simplify ecological complexity. They provide an ecologically based alternative to arbitrary administrative planning units and a logical basis for forest resource & protected area planning, assessing biodiversity, monitoring ecosystems, and stratifying sample areas for research. This report examines the regional-level units of the three ecoregionalization systems available for Ontario: Hills Site Regions (Hills, 1959); Terrestrial Ecoregions of Ontario (Wickware & Rubec, 1989); and Revised Terrestrial Ecoregions (Ecological Stratification Working Group, 1995). The objective is to quantify these systems using a multivariate set of geoclimatic variables and to determine the effectiveness of these systems in stratifying different ecological conditions in the province. The report provides descriptive statistics & principal components analysis of each regional unit, compares multivariate distances & geologic similarity among units, and examines gradients of geoclimatic variables across unit boundaries. Strengths & weaknesses of each system in delineating groups of variables (temperature, precipitation, geology, terrain) are discussed along with the implications for using existing systems & future ecoregionalization development.

For the effective management of forest land resources, it is essential to know not only the geographic distribution of these resources, but to appreciate the dynamic relationships among tree species, soil, and climate. Site-regions, as developed for Ontario, provide such an interpretation by focusing on changes in species-site relationships along macroclimatic gradients. This report summarizes, updates, clarifies, and formulates more precisely the underlying concepts of site region; outlines research methods; presents revisions of regional characterizations and of the map of site regions in Ontario; compares these regions with other regional classifications; and outlines the utility of site regions in management and ecological studies.

Finally, to introduce the concept of climate-related movement of flora and fauna, current and future climate envelopes are generated for 12 Ontario tree species that have a range of climate and site type preferences. [...] Between the monthly temperature and precipitation estimates and subsequently derived bioclimatic variables, a total of 55 climate variables were available to use in characterizing the climate of the ecoregions. [...] Given that the size and shape of maps of the climate envelope for each ecoregion will vary depending on the climate variables included in the analysis (Beaumont et al. [...] Finally, the current and future climate for each of the selected natural heritage areas was summarized for the 14 climate variables outlined above. [...] This map is a product of the Applied Research and Development Branch, Ontario Ministry of Natural Resources and the Toronto Canadian Forest Service.

The focus of this study was to estimate the distribution of ecosystem productivity in Ontario at the provincial scale and to explain the nested patterns of productivity based on geoclimatic variables. The study approach, called the Regional HydroEcological Simulation System, uses remote sensing data, geographic information systems, hydroecological simulation modelling, and spatial statistical analysis to simulate forest ecosystem processes at high resolution across a range of Ontario landscapes. The techniques developed were used to partition the province into distinct, ecologically consistent, nested zones, where geoclimatic controls explain much of the variance in productivity at the largest spatial scales and where local landforms & soils control productivity at progressively smaller spatial scales.

Collection of interdisciplinary studies describing the roles and influences that climate has had in molding the patterns and inherent qualities of our ecosystems. 'Ecoclimatic regions' are 'regions' whose delineations are based on "ecological relationships between living and non-living components of the environment."
