I. Explore Grasslandia

  Map of Grasslandia shows estimated pre-settlement (historical) distribution of Southeastern grasslands.

Zoom in and Use Various Base Maps

  Switch base maps to satellite view to zoom in on an area of interest (AOI).

Zoom in Farther to See Already Mapped Examples of Modern Grasslands

"Drop in" any point in Grasslandia to view the pre-settlement landscape (developed using a combination of vegetation modeling, artist reconstructions, and animation).

The Google Earth Street View image on left shows modern site. At right, artist reconstruction (painting by Philip Juras, www.philipjuras.com), shows what the site might have looked like in 1775.

 Vegetation models would help to inform reconstructions like that shown in the artist rendering above.

Icons Emerge that Show Evidence of Grasslands - These are "Anchor Points"

 NatureServe's Butterfly Icon = Rare Species Records; NVC Tree Icon = Vegetation Plots; Panoramio Symbol = Photos; iNaturalist Icon = iNaturalist record; "x" symbol = historical quote; Checklist icon = Site Notes and Species Checklists

"open limestone glades 5 miles south of Chattanooga" Haywood (1887)

 

Click on the "Butterfly" Icon and View Species Records Per Site

Species records will be derived from a variety of datasets including (1) NatureServe and State Natural Heritage Program Biotics Database; (2) SERNEC Herbarium Specimen Portal; (3) various museums such as Mississippi Entomological Museum; (4) VertNet for vertebrate animals; and (5) iNaturalist, etc. Clicking on each specimen record would take you to original data sources.

  1. Offer an assortment of base maps which can be overlaid to allow for mapping directly into the database (satellite, infrared, topo, soils, wetlands, landfire, landform, SEGAP - consider Ecozone?)
  2. Offer a swipe tool for easily switching back and forth between types (as in ArcGIS)
  3. allow for mapping various accessory attributes such as herbarium specimen records, etc., features that help identify grassland patches (SERNEC, VertNet, archaeological records???)
  4. mapping feature with appropriate labeling tools to allow for mapping polygons, points, etc. and labeling
  5. different accuracy settings
  6. allow for associating attribute data with mapped grasslands
    1. quotes
    2. species lists
    3. photos
    4. documents/notes
 

III. Identify Grassland Types

  1. As you zoom into a given region
  2. possible grassland types (and species - see below) are automatically filtered down
  3. clickable sets of attributes based on field observations to facilitate identification
  4. community pages offering descriptions of abiotic and biotic attributes
  5. show representative sites function
  6. show photo galleries of each type
  7. biological attributes of each type automatically filter out so you can see species per community type, plots per type, abiotic and biotic attributes of each type, geographic distribution of each type

Above: Ideally, the entire SGI focal area would be modeled using a combination of data sets to produce a vegetation map of the SGI area. As you zoom in on the map, the number of grassland types that occur within the search area decreases

 

Zooming in at the scale of #2 in the maps above results in about 15+ grassland types being identified.

Continued zooming to the scale of #4 reveals four grassland types of the Inner Nashville Basin.

Once a grassland type is identified, then you can see a profile page about that community complete with descriptions, photos. All of the known examples of that type are mapped. Can see rare species of that type, or invasive species of that type, or total flora and fauna. 

 

IV. Database (and identification?) of Grassland Species

  1. as you filter down to the community, it also filters down possible species per region or site
  2. species can be additionally selected based on site's physical attributes

V. Data Entry Tool for Documenting New Sites

handheld.png
  1. Field surveys result in discovery of new grassland
  2. Mapping function to allow for polygons or points
  3. Tool for recording physical features (certain features autofill)
  4. Tool for species documentation
  5. Tool for vegetation documentation
  6. Tool for photographic upload
  7. Tool to attach other files (photocopies of site reports)
  8. Administrators & data manager would manage site
  9. Users with passwords would be able to upload data, but data would only be incorporated officially once vetted by admin
