Spring Site Information
To view a spring's site information, click “Open Record” (the boxed pencil icon) to open the Site Information Form (Figure 10). Within this form there are eleven tabs that display information about the site that tend to not change over time. These include country, state, county, land ownership, Hydrologic Unit Code (HUC), USGS Quad, coordinates, elevation, geomorphology, geology, solar radiation budget, the survey history, management information, the site's sensitivity status, and an overall description of the site and its history. The following screen shots and figure descriptions explain the content and uses for each of these tabs. Watch this short video for an overview of site information.
The General Tab (Figure 10) includes locational information, such as Name, State, County, Land Ownership, and Land Unit Detail. This tab also includes basic geographic information such as USGS Quad, 8-digit Hydrologic Unit Code (HUC), alias names (AKA), and GNIS Feature ID (Geographic Names Information System). There is an option to choose the Treatment/Management Area from the dropdown box. In addition, the Sensitivity status of the site designates whether the Location or Survey information are sensitive, or neither or both. Some access Permissions are based on this field, along with the Land Unit Detail and whether or not the data have been published. After entering or updating data, click Save.
The Description Tab (Figure 11) includes general descriptive information about the site that tends to remain constant over time. Access Directions are entered here. This should include challenges to accessing the site (crossing private land or climbing a cliff, for example). Also it may include helpful details such as sensitive land constraints (Wilderness areas, etc.). When writing the site description, please use complete sentences and try to provide enough information that future surveyors could recognize the site from the description. Images and Sketchmaps of the site from the most recent survey, if it exists, also are displayed on this tab. However, they can only be uploaded in a survey; they cannot be entered from this form. In the Site Hyperlink field you can enter a hyperlink to an internet location that may offer more information about a spring.
The management Tab
The management tab provides a useful place for land managers to record legal information, the cultural importance of a site, and any management or restoration actions performed. The management action module allows land managers to document actions such as restoration, rehabilitation, fencing, invasive species removal, etc. If you have suggestions for this page, please email firstname.lastname@example.org
The Reports Tab
This tab is extremely useful once you have all the data entered. Here, you can generate a site or survey summary report (Figure 13) with all your data and pictures. You can also generate reports for water quality data, flow data, a plant species cover list (Stevens et al. protocol), a plant list (Stevens et al. protocol), vertebrate species, and invertebrate species. With one click, the data will be exported into a .csv file for all but the summary report, which is generated as an editable Word document.
If there are any historic reports associated with the site that you would like to upload, you can also do that here in PDF format.
The Surveys Tab (Figure 14) displays the Inventory Level and the Survey Status (highlighted in Fig. 14), as well as the Survey Records of the spring site. The Inventory Level allows project managers to track whether or not a site has been surveyed. Survey Status indicates the extent of data (EOD) most recently collected (i.e. Site Surveyed, EOD (>7).
Survey records include a display of the Date the survey data was conducted, in the format yyyy-mm-dd, the extent of data collected (EOD, a numerical value between 1 and 11 that represents a count of categories that contain data), the Project name and Surveyors' names. Clicking on the Date field opens the survey. There can be many surveys for each location. The list can be sorted in ascending or descending order by any category by clicking the arrow symbol in the column heading.
The Polygons Tab (Figure 15) shows the names and any comments associated with the Polygons (microhabitats) at the site. Each polygon is given an alphabetic Code, (A, B, C...) as well as a Name. These may be applied to any number of future surveys, if appropriate. Detailed microhabitat characteristics (Soils, Vegetation, Moisture, Aspect, etc.) are not applied to the Site Polygon described here, but to the Survey Polygons described later. Should the geomorphology change, new microhabitats may be added. Click the Add Polygon button to add a new microhabitat. Should surveyors not identify microhabitats, the Entire Site is labeled Polygon X. Notice that when any data associated with a site are changed, the user name and date are recorded at the bottom of the form. As is the case throughout the database, this list may be sorted in ascending or descending order using the arrows in the column heading. Please note that you must add and label a site’s polygons here before they can be associated with a survey.
This tab (Figure 16) contains the georeferencing information. Coordinates MUST be entered in NAD83 or WGS84. If coordinates are collected in NAD 27, it is important to convert them correctly. Use http://www.ngs.noaa.gov/cgi-bin/nadcon.prl or another accurate conversion website. Please note that if the Datum field is left blank, the point will not be considered accurate and will not be exported into a geodatabase. Users may enter UTMs or Latitude/Longitude, either in Degrees, Minutes, and Seconds or in Decimal Degrees. Whichever values are entered, the database will calculate the others. You can also view and edit the location on a map by clicking the globe symbol. From this map you can also move the location and click Submit Coordinates. Elevation and Estimated Position Error should be entered in meters. If these were collected in feet, enter "ft" after the value (e.g. 4500ft), and the measurement will be converted to meters. As noted previously, many springs are inaccurately mapped. Should you feel compelled to change the coordinates to correct the location, please briefly explain in the Georeference Comments, and revise the Georeference Source and GPS Unit as appropriate.
The mapping aid (accessed via the small globe icon next to longitude) can be very useful if the estimated position error on your device is significant. If you select the satellite layer and zoom in (Figure 17), you can often clearly see (particularly in arid lands) the source of the spring, and the point may be mapped several meters off. If this is the case, you can drag and drop the point, then click “Submit Coordinates” to move the refined point. Please be careful with this feature though. It can be relatively easy to drag and drop points, thus moving the spring, when you do not intend to. If this happens, simply close the mapping aid and the changes will not be saved.
The geomorphology field sheet (Figure 18) should be completed by the team’s hydrogeologist. Geomorphology information includes the Spring Type (Sphere of Discharge). These include cave, exposure, fountain, geyser, gushet, hanging garden, helocrene, hypocrene, limnocrene, rheocrene, hillslope, mound-form, and anthropogenic (those that are so heavily manipulated that they no longer resemble their original form). Keys to these designations are displayed in the dropdown form. They are also fully described, with example photographs and diagrams, here. Although most springs have only one type of discharge sphere, some complex sites may have two or more. Other fields on this tab include Emergence Environment, Flow Force Mechanism, Primary Lithology, and Secondary Lithology. When a Primary Lithology is entered, only appropriate Secondary Lithologies will be listed in the dropdown box for that field. For example, upon entering “Sedimentary” as the Primary Lithology, the Secondary Lithology will be limited to “sandstone, limestone, shale, etc.” The name of the Geologic Layer and other geologic factors may be entered if known.
The solar radiation that reaches a site can be estimated using a Solar Pathfinder TM. This relatively inexpensive device displays the sunrise and sunset at the source. The data should be entered in 24-hour time as hh:mm. Upon entering these, click the Calculate Energy and Save Buttons to calculate the seasonal energy budget in Mj/m2 and percent of potential energy for the site. The Latitude value must be entered in order for this function to work. Should there be no obstruction at the site, click the No Obstruction Button to automatically enter the values. This function also requires a latitude value.
The EOD Tab also lists the Survey Date, but displays ”x” symbols that identify the categories that contain data. In this example, the 1994-04-30 survey has two categories of information, while the 2008-12-11 survey has ten. Only Georeferencing and Invertebrates are present in the former, while all 10 categories were assessed (including the SEAP) in the latter.
The last two tabs on the site form include History, which documents changes to the site information by login name and the date changed. The Admin Tab enables Administrative users to change the site name or delete sites. A site may not be deleted if there are surveys associated with it.
The next section of the tutorial explains the process for recording individual site surveys. To open a survey, select the Surveys Tab and click on the Survey Date. This hyperlink will only be active if you have Permissions to access the survey.
