- 303 - This is basic to resource management as well as to impact assessment. Airborne and satellite remote sensing may help to identify, classify and describe the building blocks of our environment. Ecosystems can be defined as any area of nature that includes living organisms and non-living substances to produce an exchange of materials between living and non-living parts (Odum, 1961). The non-living parts of an ecosystem are collectively known as ’physiography’, consisting of both landform and climate. Plants, animal and human communities comprise the living portions of the ecosystems (Hills, 1970). Because of the relative stability landform features are frequently used to classify ecosystems. During the last decade only have there been attempts in Canada to survey and provide resource data in a multidisciplinary and integrated fashion— the Canada Land Inventory System and the Bio-physical Land Classification System (Lacate et al, 1970) are examples of this. However, in addition to these integrated surveys, single disciplinary resource monitoring will still be required. For adequate monitoring of environmental phenomena at least monthly or seasonal surveys are needed over large areas. In Canada very few regularly repeated airborne surveys have been carried out and ERTS-1 imagery is the only source of information which has been gathered with reasonable frequency (18-day interval) and resolution (about 80 meters on the ground). ERTS covers all areas; data is provided rapidly for areas that are of immediate interest and a file of information is built up for areas which may be of future concern. Many of the following discussions are therefore related to ERTS-1 applications which are usually combined with selected airborne surveys. The bio-physical land classification system is an ecological survey which uses the relatively stable landforms as a basis for ecosystem mapping. Such a survey provides information related to the ecological limitations and is a prere quisite to integrated resource management (Jurdant et al, 1974). Four different levels are identified in the system: land region, land district, land system and land type. ERTS remote sensing can contribute to the mapping, description and monitoring of these units as it builds up a file of information on environmental dynamics covering large areas on the earth’s surface; the data may include snow cover, snow melt, freezing and thawing of lakes, phenology of vegetation, etc. Such information, collected over a period of time, may assist in the delineation of areas with ecologically significant uniform climate. For example, the melting of snow and lake ice (Fig. 1) correlates strongly with land region (ecoregion) boundaries which were obtained after extensive field work. These climatically defined larger units (mapping scale usually 1 : 1 , 000,000 or smaller) can be broken down into the next level (land district; scale of mapping 1:500,000 to 1:1,000,000) on ERTS imagery. While satellite imagery can help in the mapping of land systems, the description of land systems will have to be based on a description of land types (ecosystems). For the analysis and description of these building blocks airphoto interpretation is essential and cannot be replaced at the present time. In areas where relatively simple relationships exist between vegetation and soils and where little disturbances have occurred, such as by fire, satellite mapping of land systems may become effective. Such areas include Arctic and sub-Arctic environments, as well as large wetlands. In the more complex areas, such as the Boreal zone of the Precambrian Shield, most mapping and monitoring will have to be carried out on airborne imagery (Thie et al, 1974).
