Searching for Plants
What Grows Here?
What Grows Here? can display a thorough plant list for a chosen area of the state in several formats. Select the area by moving and zooming the map, or draw a polygon, or choose a polygon from a background layer, such as the boundary of a State Park.

WGH provides some interesting ways to visualize plant data -- for instance, displaying the locations of several plants on the map at the same time, using a different icon for each plant.

The What Grows Here? Wizard is available to help find a location in California. Starting from the wizard, you will end up in the map application.

RELEASE NOTES

Icons and Palettes
To view the locations of a plant on the map, you have a choice of various colored icons. The default icon is a blue point:

A palette is a set of plant - icon assignments. As you choose icons to display various plants in the results, you are implicitly making a custom palette. Custom palettes can be saved and used again. Here is an example:

Favorite North Coast plants:

EXPLORE the locations of these plants relative to one another, starting in Fort Bragg.


Advanced Search for Plants
This application provides for combinations of search criteria not available from the regular Search for Plants, such as:
  • Does USDA PLANTS recognize the name?
  • Are photos available on CalPhotos, or not?
  • Can it tolerate a soil pH of 4.0?
  • Does it bloom in January?


May, 2015. This application will also search for the plants found in a county, with a selectable level of evidence (the minimum number of observations of the plant in the county). So for instance, you could search for plants for which there are at least five observations in Del Norte County.

This application can show a list of plants in a three-photo format (similar to the Illustrated Plant List), or as plain text (easily imported into a spreadsheet or database).

Search for Plants
August, 2015. The classic Calflora home page search interface, remade:

    • A new search criterion, Duration, now distinguished from Lifeform;
    • Elevation and other seldom used search criteria hidden at the bottom.

Calflora Mobile Search for Plants
a smart phone application for looking up wild plants by name or characteristics.


 
Searching for Observations

Observation Hotline
to search for observations with the help of a Google Map. This application shows contributed photos when they are available.

It is possible to limit the geographical extent of the search to
  • the visible map area
  • a drawn search polygon (the same as What Grows Here?)
  • the boundary of a background polygon, such as a park
  • a county (check Tools / Advanced Form)

    Calflora Field Methods

    Define your own plant lists for use in the smart phone applications.


    Plant Observation Entry
    to view, enter or edit a plant observation record.

    Photos can be uploaded directly from your computer to become part of your observation record.

    If your photo is already on the web (e.g. on a web photo service like Flickr or Picasa, or on your own website), you can add the URL of the photo to an observation record.



    Photo-to-observation File Upload
    to transform photos of plants into observation reports. If a photo is geotagged, the software will pick up the location; otherwise, you can set the location on a map when you edit the record in Plant Observation Entry.

    Checklist Entry
    to enter a checklist (many plants observed at one location).



    Adding Lines and Polygons
    The entry applications include the ability to add a line or polygon to a record. Use it to describe the spatial extent of an plant population, or the area covered by a survey or checklist.

    For example, Jerry Baker added this polygon to describe the extent of a patch of Astragalus Brauntonii, Baunton's milk vetch, in Los Angeles Co. (This screen shot is from the Plant Distribution application. Note the blue point showing through, which is a previous record of the same plant.)

    Observation Upload
    to upload an entire dataset directly into the database.

    Copy and paste from a spreadsheet, or upload a shapefile. During the process, you assign fields in the dataset being uploaded to fields in the Calflora database.

    HELP

    When you upload a shapefile, the server will take it apart and return the data to this application. Then you assign the attributes from the shapefile to database fields.

     
    Searching for Places
    Great Places to view California native plants
    The Great Places project highlights certain places in the state which are particularly good for viewing native plants.

    Contributors: there are planty of great places out there waiting to be added or adopted. If you have already made a bunch of observations with photos in a particular area, then that area would probably make an excellent Great Place.


    The places can include both wild locations and gardens where natives have been planted. There are three component applications: a home page, a page about a particular place, and an editor for adding a new place page.

    Here is what Calflora hopes to accomplish with the Great Places project: By highlighting certain places, contributors will be encouraged to make additional plant observations in those places. Over time, the native vegetation in those places will become better documented.

    Checklist Browser
    to search through all available checklists on a map.

    Press illustrated version for a printable version of a checklist -- two photos of each plant -- suitable for use as a field guide.



    Here is the application showing checklists for most California State Parks. (Many thanks to Mona Robison and Paul Veisze for making this possible.)

    Plant Information
    Taxon Report
    2015 May: Watch this YouTube VIDEO describing the Taxon Report page!

    The map on the Taxon Report page indicates plant presence by means of points and quads (instead of by colored counties).


    The map shows elevation in colors inspired by a classic USGS map. Mouse over the map to see county names, and click on the map to see all records from that county in Observation Hotline.

    From the Taxon Report page, there are prominent links to Example: the page for Eriophyllum confertiflorum (golden yarrow).


    Plant Characteristics and Associations
    This page shows the climate and soil tolerances of a plant (the conditions under which the plant will grow). Press the Location Suitability link on this page to match plant tolerances with the climate and soil factors of a particular location.

    This also page shows what other organisms are associated with a plant, both beneficial and pest. Data about native bees and other beneficial insects (which plants they favor) are from the XERCES SOCIETY.


    From the Taxon Report page for a particular plant, press the Plant Characteristics link in the center.

    You can also use What Grows Here? or Advanced Search to look for plants associated with, for instance,bees.

    Plant Distribution
    shows the statewide distribution of a plant as a variable cell size grid, or as points.

    From the Taxon Report page for a particular plant, press the Distribution Grid link.

    The cells are colored to make a heat map, indicating where a particular plant has been observed the most. For instance, this page for Rhamnus ilicifolia, hollyleaf redberry.



    HELP

    This application can show shape data (lines and polygons) when available. The grid is an interesting way to bring point data and shape data together on the same map, at whatever scale.

    Here is an example polygon for a weed in Marin Co.:

    Cytisus scoparius (scotch broom)
    in Corte Madera
    (Marin County Open Space District)

    From the Tools menu, click to see plant distribution in Google Earth.

    Bloom Period
    is shown on over 9,000+ Taxon Report pages. (See this note for more about bloom period and the sources of the data.) For example, see this page for Madia elegans.

    An illustrated plant list can also show bloom period, and sort by the bloom start month.

    The Advanced Search for Plants application supports searching by a bloom month; for instance, plants that bloom during June.

    Elevation
    November, 2013: The elevation values of all observation records were updated, in meters, by referencing the point location against a digital elevation model.

    Also, whenever you edit an observation record in Plant Observation Entry, and change the point location, you can see the elevation of the new location immediately by pressing lookup elevation. The application will also update the elevation value automatically when you save the record. The elevation value comes from the Google Maps Elevation API.

    Accurate elevation values can be important in predicting where a plant will grow.

    The elevation range of each plant was recently derived by analyzing the elevation values of observations of that plant. The elevation range in meters is reported on the Plant Characteristics page.


     
    Contributor Services
    Comment on Observations
    There is a comment system for observations. If you are registered as a contributor, you can add a comment on any observation record.

    From My Calflora / Comments, you can look up all the comments you have made, or all the comments others have made about your observations.

    Informed comments can be a helpful source of feedback to the person responsible for an observation. For legacy observation data (where the observer is no longer accessible), comments can also help Calflora volunteers and staff to get erroneous records out of the way.
    Customize your Calflora Experience
    From My Calflora / Preferences, you can specify your own center point for observations. This becomes the starting point for various applications, including Plant Observation Entry, My Observations, and Observation Hotline. (If you haven't specified a center point, these applications start near Fresno.)

    If you belong to groups, you can specify a default group for all of your new observations.

    It is also an option to ask for email notifications when there is new activity in one of your groups, or when there are new comments about your records.

    My Observations
    to review, edit and publish your observations.


    Plant List Definition
    to define your own plant lists to be used in the Observer and Observer Pro smart phone applications, and in search applications.

    Certain special purpose plant lists (BAEDN Priority Weeds, Cal-IPC Priority Weeds) are available for all users.


    Cut and paste a list of plant names from anywhere. Accepts older scientific names, and resolves them to current Calflora names.

    Press illustrated version for a printable version of a list -- two photos for each plant.

    Observation Download
    to search for and download observations in a variety of formats.

    Shapefiles are available as an Output Format. Choose from Shapefile: point, Shapefile: line, or Shapefile: polygon.

    HELP




    Search for records of a particular plant, set Output Format = KML and press Download File to view the results in Google Earth. If there are any lines or polygons in the results, you will be able to see them in Google Earth.
