These data are referenced (keyed) to the map units of the Soils of Canada map, 1:5,000,000. Other types of data, derived from studies using input from these main files, or containing links to other types of information, ego Census of Agri- cu lture or crop reporting districts, etc., are included as well, but these are reported in the appendices. The first part of this public- ation gives an overview of the basic files contained in the data base, and lists the names of the variables to be found in each file. The Land Potential Data Base is the only comprehensive, national source of information on the land resources of Canada. These data have been used for various kinds of studies, such as crop yield potentials, soil degradation, land use diversification, climate change, production risk assessment, and so forth. Information from this data base can be supplied on diskettes by submitting a written request. 4 RESUME La banque de donnees sur les possibilities de production des terres (BDPPT) est un ensemble de donnees informatisees regroupant des renseignements sur les sols, Ie climat, la physiographie, l'utilisation des terres, les rendements optimaux dans des conditions ideales, les rendements culturaux reels et la degradation des sols dans toutes les regions canadiennes. Ces donnees sont traitees selon les unites graphiques utilisees sur la carte des sols du Canada, a l'echelle 1: 5000 000. D'autres types de donnees tirees d'etudes au cours desquelles on s I est servi des renseignements provenant des fichiers principaux ou ities a un autre genre d'information, p. ex., Ie Recensement de l'agriculture, les rapports de districts sur les cultures et autres, sont egalement incluses, mais elles sont mises en annexe. La premiere partie de cette publication donne un aperyu des fichiers fondamentaux regroupes dans la banque de donnees et enumere les elements que l'on trouve dans chaque fichier. La banque de donnees sur les possibilites de production des terres est la seule source d'information complete sur les ressources en terres au Canada.

Dumanski and J. Hardy Soil Suitability 7 INTRODUCTION The Land Potential Data Base for Canada (LPDB) is a computerized information base containing data about soil, climate, land degradation and modeled and actual crop yields for the major economically important crops in Canada. This information is summarized for each of the 755 soil map units designated by the Soils of Canada map (Clayton et al., 1977). This version of the data base has been updated from that developed as part of a global assessment of agroecological crop production potentials (FAO, 1978). It has also been put onto a different data base management system (DBMS) and it exists currently as several relations in a PC INFO data base management system. The organization of the data remains relational, but there have been some logical regroupings of data (eg. climate variables, soil degradation variables, etc.) into separate relations. Also, this revised LPDB includes actual yield data derived from provincial agricultural statistics, which were not in the original version. The common key remains the soil map unit. This new version of the data will be available for distribution on diskettes. The first section in this handbook contains information on each of the data files in the LPDB. Appendix I contains information on files which are associated with the LPDB, but because of their specialized nature have not been included in the main body of data. Appendix II contains a detailed description of each of the data files stored in the LPDB, including specific item names, formats, and brief definitions of the data to be found in each item. Extended definitions for some of the more complex data file items will be found in Appendix III. A complete alphabetic listing of all the items in all of the files in the data base will be found in Appendix IV, along with the name of the file in which it is to be found. DATA FILES CONTAINED IN THE LPDB CLIMATE VARIABLES (Data files CLlMATE5180 and GROWSEASCLIM) * The climate data in the LPDB have been updated to the 1951-80 climate normals (Atmospheric Environment Service, Environment Canada), except for vapour pressure and windspeed, which remain as 1941-70 normals. The method used for averaging the climatic information from station data to polygons was improved, especially in the Prairie regions. In particular, instead of using 100 km grid averaged data, actual station data were used to represent many of the polygons.** *Data file names are given in the form in which they must be used during a PC INFO retrieval request. All listings of data files begin with MAPUNIT because the mapunit number is the standard reference for all variables in the LPDB. All other variables are subsequently listed alphabetically. **Certain of the map units are known to contain errors in climate data. These errors may be due to selection of inappropriate climate stations to represent these areas, and/or they may be caused by the methods of data analyses. These map units are B2012, D3124, F3060, H1028, H3048, and H3054. 8 Therefore the climatic variables cannot be compared directly between the old and new versions. Several new variables have also been included: corn heat units and days required to reach 2000, 2200 and 2300 CHU, degree days greater than 5.0°C, and daylength. For ease of use, the climate variables have been split into two files, one containing monthly data, and the other containing growing season information. These files are named CLIMATE5180 and GROWSEASCLIM respectively. The following is a list of the variables in CLIMATE5180: MAPUNIT DL(month) PE(month) RAIN(month) SMHC SNOW(month) SOLAR(month) TMAX(month) TMEAN(month) TMIN(month) VAPOUR(month) WIND(month) The definition of each of the above variables can be found in Appendix II, page 16. The following is a list of variables in GROWSEASCLIM: MAPUNIT AGSL CHU DEGDAY5 GSEND GSSTART MNDAILYPE MNDAILYRAD MNDAILYT MNDAYTIMET MNMAXDAILYT MNMINDAILYT N2000 N2200 N2300 RAIN VAP WIND The definition of each of the above variables can be found in Appendix II, page 17. SOIL DESCRIPTION AND SOIL CLIMATE VARIABLES (Data files SOILINVENTORY, ACRI and SOILCLIM) Most of these fields have been moved from the old to the new LPDB with no changes in name or format. The two files, SOILINVENTORY and SOILCLIM summarize the information available in Soils of Canada, Volume 2, Inventory (Clayton et aI., 1977). ACRI, the agroclimatic resource index, is a comparison of quality of the climate for agriculture in dif- ferent regions of Canada (Williams, 1975). A more comprehensive description of the ACRI variables may be found on page 41, Appendix III. It is possible to show extra detail for some of the information in the data base by attaching numbers to field names, ego LANDUSE1, LANDUSE2 etc. In these cases, the dominant description will be in field 1, while significant inclusions (if any) will be found in subsequently numbered fields. These numbers do not imply any weighting factor, nor do they specify spatial distribution of these attributes within each map unit. 9 The following is a list of variables in SOILINVENTORY: MAPUNIT DIVISION DOMSTI DOMSTIM DOMST2 DOMST2M DOMST3 ELEVHI ELEVLO FAONUMOD FAOSLCL FAOSTI FAOST2 FAOST3 FAOTEXT GREATGR LANDFRMI LANDFRM2 LANDFRM3 LANDUSEI LANDUSE2 LANDUSE3 LANDUSE4 LATDEG LATMIN LONGDEG LONGMIN PHASE PMl PM2 PM3 PM4 PMlMOD PM2MOD REGION SIGSTI SIGSTIM SIGST2 SIGST3 SOILAREA SOILUNIT SUBSTI SUBSTIM SUBST2 TEXTURE 1 TEXTURE2 TOPOCLAS XCOORD YCOORD Definitions for these variables may be found in Appendix II, starting on page 18.

  • Coppermine River Nomination Document
    Coppermine River Nomination Document Government of Nunavut Parks and Tourism Division Department of Sustainable Development Coppermine River, Nunavut Nomination Document Parks and Tourism Division Department of Sustainable Development Community of Kugluktuk 1 2 Canadian Heritage Rivers System The Canadian Heritage Rivers System has been established by federal, provincial and territorial governments to recognize Canada’s outstanding rivers, and to ensure future management which will protect these rivers and enhance their significant heritage values for long-term benefit and enjoyment of Canadians. To qualify for inclusion in the Canadian Heritage Rivers System a river or a section of river must be of outstanding significance in one or more area; human heritage, natural heritage or recreational values. The nominated section should also be large enough to encompass these values and to provide the user with an appreciation of the river’s resources, as well as an enjoyable recreational experience. The responsibility for the collection and analysis of information to determine heritage values and for subsequent nomination of the river rests with the particular government within whose jurisdiction the nominated river lies. The Canadian Heritage Rivers Board, composed of federal, provincial and territorial repre- sentatives, will examine each nomination document and advise the Minister responsible for Parks Canada and the Minister(s) of the nominating agency (ies) on the suitability of the nominated river for inclusion within the Canadian Heritage Rivers System. When consider- ing a river, the Board will determine the degree to which the nominated river satisfies the “Guidelines for the selection of Canadian Heritage Rivers”. The Board will consider both the river and its surrounding landscape which together capture the heritage values.

Manitoba 11 ABSTRACT In 1986, a zone of high arsenic values in till was outlined south of Wheatcroft Lake in northwestem Manitoba. This zone was based on 8 anomalous samples taken over an area of approximately ~OO km2• As a folIow-up to this study, 128 additional till samples were collected in the same area. Dispersal patterns of go Id and arsenic are parallel to sub-parallel to Wisconsinan ice-flow directions. No one source area or bedrock lithology has been outlined. Several sources probably contribute to anomalous gold and arsenic values. Much of the study area is overlain by clay of glacial Lake Agassiz. Overlying clay was sampled in addition to till to determine whether clay geochemistry reflects the geochemistry of underlying till. For most trace clements, Lake Agassiz clay is unreliable for detecting the geochemical signal of underlying till. Uranium levels in overlying clay may reflect uranium concentrations in till. 1ll RÉSUMÉ En 1986, de hautes teneurs en arsenic furent observées dans une région dc till au sud du Lac Wheatcroft, dans le nord-ouest du Manitoba.

    May 2011 206 Blachford Lake had relatively low chlorophyll a values in June and September (0.626 and 1.42 µg/L), while Dinosaur showed high values. Dinosaur also had the highest chlorophyll a across the study area in September (14.60 µg/L), increasing nearly three-fold from June (4.90 µg/L). Phytoplankton richness, diversity and predominant taxa were similar in both lakes, with slight differences in species composition. In Blachford Lake, one blue-green species (Lyngbya limnetica) was predominant and in Dinosaur Lake, two blue-green species (Lyngbya contorta and L. cf. limnetica) were predominant. Dinobryon spp. (yellow-brown algae) were common in both lakes. Zooplankton richness and diversity were relatively high in both lakes, though higher in Blachford than Dinosaur. Rotifers were predominant in both lakes, with four main species in Blachford and two species in Dinosaur. Benthic invertebrate taxon richness and diversity were higher in Blachford than in other lakes of the study area samples in 2009. Richness and diversity values were moderate in Dinosaur, and evenness was moderately low in both lakes. Amphipoda and Chironomidae were predominant in Blachford and Dinosaur lakes. No fish sampling was conducted in Dinosaur or Blachford lakes during the Stantec (2010c) studies. Sampling in the south bay of Blachford Lake in June 1998 resulted in the capture of 55 fish by gill netting and angling. Fish species captured were: northern pike, lake cisco, lake whitefish, and lake trout. 2.8.6 Great Slave Lake 2.8.6.1 General Description Great Slave Lake is the second largest lake in the Northwest Territories (behind Great Bear Lake), the deepest lake in North America at 616 m (2,027 ft.), and the sixth largest lake in the world.

OS-8497-OOO-EF-AI Catalogue No. R71-461l993 ISBN 0-662-21589-3 © Minister of Government Services Canada EXECUTIVE SUMMARY The Department of Indian Affairs and Northern Development (DIAND) has responsibilities for encouraging economic development in Canada's two northern territories and ensuring that these activities are conducted in an environmentally responsible manner to prevent any deterioration to northern ecosystems. Interactions between mining and the environment are of prime importance, not only to resource managers and regulators, but also to residents who rely on natural resources for their lifestyle or for economic development opportunities. DIAND provides funds for two programs that deal with mining and the environment: the Northern Water Resources Studies Program and the Mine Environment Neutral Drainage Program. To be effective, DIAND must bring together a broad range of interest groups to help set priorities for further mining and aquatic ecosystem studies. .Over the last two years, the Water Resources Division has sponsored a series of workshops to review the current state of knowledge about the interactions between northern mineral development and aquatic ecosystems, to identify critical information or research gaps and to devise a study program to fill those gaps.

Through the Nunavut Agreement, an Inuit Impact and Benefit Agreement for National Wildlife Areas and Migratory Bird Sanctuaries in the Nunavut Settlement Area (IIBA) was signed by Nunavut Tunngavik Inc., the three Regional Inuit Associations (Kitikmeot Inuit Association, Kivalliq Inuit Association and Qikiqtani Inuit Association) and the federal Minister of the Environment, Environment and Climate Change Canada (signed first in 2006 and renegotiated in 2016). This IIBA created co-management committees for these protected areas in Nunavut (IIBA Article 3). The Ahiak Migratory Bird Sanctuary is co-managed by Inuit (from Umingmaktok, Cambridge Bay and Gjoa Haven) and the Canadian Wildlife Service (a part of Environment and Climate Change Canada) through the Ahiak Area Co-Management Committee. Part of the mandate of the Ahiak Area Co-Management Committee is to develop a Management Plan for the Ahiak Migratory Bird Sanctuary (IIBA s. 3.2.3(b) and s. 3.5). The Ahiak Area Co- Management Committee completed a draft Management Plan and consulted with the associated communities and other interested parties on the draft (IIBA s. 3.5). As per the IIBA, 3.6.1 The ACMCs [Area Co-Management Committees] shall recommend completed Management Plans to the NWMB [Nunavut Wildlife Management Board] for approval in accordance with sections 5.2.34(c) and 5.3.16 of the NLCA [Nunavut Agreement].
