A forest ecological land classification in southeastern Manitoba resulted in the description of 14 forest habitat types, including three subtypes. These are based on silviculturally significant differences of soil moisture and nutrient regime, which are interpreted through tangible features of the three ecosystem components: vegetation, soil, and landform. The types encompass the regional environment from the driest habitats on sand dunes to the wettest in low moor bogs and from the nutritionally poorest on siliceous sandy podzols to the richest on alluvial bottomlands.The classification is to serve as a basic framework for silvicultural practices in the area. Aspects of application to current forest management are discussed.

Forest Site Classification

Forest site classification is a prerequisite to successful integrated forest resources planning and management. Traditionally,site classification has emphasized a phytocentric approach, with tools such as the site index having a rich and longhistory in forest site evaluation. The concept of site index was primarily devised to assess site productivity of an even-aged,single-species stand. Site index has been the primary method of forest site evaluation in support of management for traditionalforest products. However, this method of site classification has been criticized as the needs, perspectives andsocial values of the public regarding forest management have changed the emphasis from timber production to multiplevalueforestry practices. There are alternative approaches to forest site classification that have the potential to meet thegrowing demands placed on forest information for inventory and modeling purposes. Ecological Land Classification(ELC), is a phytogeocentric approach that stratifies the landscape into ecologically meaningful units (ecosites) based onsubstrate characteristics, moisture regime and canopy composition. This approach offers a more holistic view of site productivityevaluation; however, until recently it has been difficult to acquire data to support widespread mapping ofecosites. Remote sensing technology along with predictive modeling and interpretive mapping techniques make the applicationof an ecosite-based approach at the forest landscape level possible. As forest management moves towards the considerationof a broader set of resources (e.g., woody biomass), there is an opportunity to develop new tools for linking forestproductivity to the sustainable production of forest bioproducts with forest ecosites as a solid foundation forsegmenting the landscape. Key words: forest site classification, site index, site productivity, Ecological Land Classification (ELC), ecosites, forest biomass,bioproducts

The Common

The cores and boundaries of land units are located by reference to relationships between climate, landform and biota in ecological land classification. This appeal to relationships, rather than to climate, or to geomorphology, or to soils, or to vegetation alone, provides the common basis for land classification.

Se han propuesto distintos criterios para medir la diversidad a nivel local (alfa y beta diversidad) a nivel regional (gama diversidad) y también a nivel del paisaje (ecodiversidad). De todas estas aproximaciones a la complejidad biótica en los ecosistemas, la ecodiversidad permite conocer la disponibilidad y la conectividad entre hábitat y lograr una idea de la variabilidad espacial de los ecosistemas. Se presentan siete índices de ecodiversidad y se discute sus ventajas y desventajas para el análisis de paisajes muy disturbados. Se analizó el paisaje del Establecimiento Las Marías, en el NE de Corrientes, que tiene algo más de 30.000 ha, comprendiendo 12.000 ha de sistemas forestales nativos y cultivados y 18.000 ha. dedicadas a té, yerba mate y policultivos. Se utilizó imágenes Landsat 7 y el procedimiento de Ecological Land Classification (ELC), para identificar las principales unidades de paisaje (bosques, pasturas, cuerpos de agua, diferentes cultivos). Se encontraron tres subsistemas de paisaje diferentes, se obtuvo información del número de polígonos y de la superficie comprendida en cada uso del paisaje y se la comparó cuantitativamente mediante varios índices. Se concluye que una determinada unidad de paisaje puede tener muy diferente diversidad, según el contexto de paisaje en el que se encuentre incluida.

Ecological Land Classification

After a brief review of floristic classifications, ecological survey, as carried out in Quebec, is described. Three stages of development of ecological survey over the past twenty-five years are identified: (1) the pioneer work of Jurdant; (2) major ecological surveys from the late 1960s to the late 1970s; and (3) the diversification of the groups involved in ecological land surveys beginning in the 1980s, including universities, the Quebec Environment Department (MENVIQ) and the Quebec Department of Energy and Resources (MER). Intended for use in integrated land management, ecological survey must be an effective integrator of the various ecological evaluations; the information must be easily communicable and the methodology must be flexible. Ecological land classification has two dimensions: (1) taxonomic; and (2) cartographic. In the taxonomic units, the ecological region, the ecological type and the ecological phase are identified. In cartographic terms, local (ecological phase and type), regional (ecological system and subsystem) and national (ecological district and region) resolution is identified.Quebec universities, MER and MENVIQ are presently involved in ecological land surveys. The new Forest Act, which was enacted in 1986 and which provides for sustainable yield and more intensive forest management, is a major force behind the promotion of the use of ecological inventories as the basis for management activities. Mapping of the ecological regions (1:1,250,000) has almost been completed in Quebec. Total coverage of the commercial forest as a function of ecological districts (1:250,000) could be completed within five years, and the mapping of ecological types (1:20,000) could be completed in 20 years at a rate of 10,000 km2 a year. Although in the past ecological land surveys have been used primarily for environmental impact analyses (for instance, the installation of hydroelectric equipment and transportation corridors), the ecological framework is presently being used to prepare development plans for a number of regional county municipalities (RCMs). Pilot projects are under way to assess the potential applications of the ecological framework to forestry as part of intensive management efforts. Improvements are needed in both the accessibility of the information provided by the ecological framework (maps, site guides) and the development of interpretative tools for silvicultural measures. Key words: ecological survey, ecosystem mapping, ecological land classification, forest ecology, forest site classification, Quebec.
