  1. Title: Distribution Maps and Models for 13 Invasive Plants in Minnesota

    Contributors:

    Summary: This dataset consists of raster (.tif) and map (.png) files for 13 invasive plants in Minnesota. Species included consist of: common buckthorn, glossy buckthorn, multiflora rose, garlic mustard, Canada thistle, common tansy, leafy spurge, spotted knapweed, wild parsnip, purple loosestrife, Japanese knotweed, narrowleaf bittercress, and plumeless thistle. The rasters (.tif files) included here consist of the output of species distribution modeling (SDM) conducted for each species; these files depict the mean cross-model and cross-assumption distribution estimates for each species, on a scale of 0 to 1. Values near 0 indicate low likelihood of finding the species there, or low habitat suitability, and values near 1 represent a high likelihood of finding the species. The maps (.png files) included here depict the same information, but in a static non-GIS compatible format.

  2. Title: White-tailed deer density estimates across the eastern United States (2008)

    Contributors:

    Summary: In 2008, the Quality Deer Management Association (QDMA) developed a map of white-tailed deer density with information obtained from state wildlife agencies. The map contains information from 2001 to 2005, with noticeable changes since the development of the first deer density map made by QDMA in 2001. The University of Minnesota, Forest Ecosystem Health Lab and the US Department of Agriculture, Forest Service-Northern Research Station have digitized the deer density map to provide information on the status and trends of forest health across the eastern United States. The QDMA spatial map depicting deer density (deer per square mile) was digitized across the eastern United States. Estimates of deer density were: White = rare, absent, or urban area with unknown population, Green = less than 15 deer per square mile, Yellow = 15 to 30 deer per square mile, Orange = 30 to 40 deer per square mile, or Red = greater than 45 deer per square mile. These categories represent coarse deer density levels as identified in the QDMA report in 2009 and should not be used to represent current or future deer densities across the study region.

  15. Title: Whitehaven, England, 1791 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Plan of the town & harbour of Whitehaven in the county of Cumberland from an actual survey anno 1790, by J. Howard ; engraved by J. Russell. It was published by J. Howard in 1791. Scale [ca. 1:2,500], 264 yards = 9.8 cm. The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'British National Grid' coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, landmarks, open spaces, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also vignettes of the Castle; St. Nicholas Church; Trinity Church; the Harbour; St. James Church. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  20. Title: Carbon Opportunity Cost of Present-Day Pasturelands and Animal Feed Crops

    Contributors:

    Summary: This multi-band raster data represents estimates of carbon opportunity cost. The data is captured at a resolution of 5 arcminutes over the global domain and is derived from data collected approximately over the past two decades (2000-2020). The pixel values measure estimates in tonnes of potential vegetation per hectare that are suppressed by pasturelands and present-day feed crops. The bands represent three estimates of carbon in potential vegetation: median, low (5th percentile), and high (95th percentile). This data is released with an Attribution 4.0 International (CC BY 4.0) license. Users may cite this collection with https://doi.org/10.17609/q5pe-7r68/.
