Applications

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 / My 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.

Center Point for Observations
From My Calflora / My Views, you can specify your own center point for observations. This becomes the starting point for various applications, including 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 also specify a default group for all of your new observations.

Plant Distribution Grid
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, Rhamnus ilicifolia, evergreen buckthorn.

 

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

Most of the shape data are weeds. For example:

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

From the Links menu, click to see plant distribution in Google Earth. See also the Help Page for Plant Distribution.

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

Many thanks to everyone who has taken the time to contribute their observations and the amazing photos.

Places to View California Native Plants
to surf through all available checklists on a map.

 
There are over 21,000 checklists in the database. Here is the application showing checklists for most California State Parks. (Many thanks to Mona Robison and Paul Veisze for making this possible.)

Press
full page version for a printable version of a list -- two photos for each plant -- suitable for use as a field guide.
 

Bloom Period
is now shown on many Taxon Report pages, such as this page for Madia elegans.

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


 

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

Plant Observation Entry
to enter observations one at a time.
2012 February 10: Version 1.51 released, with Google Maps V3.

Weed Observation Entry
including extra fields for weed work.
2012 February 27: Version 1.53 released, with Google Maps V3. Also, there is a new Number of Plants field, and the range values of Canopy Closure (Percent Cover) have changed.

The entry applications now offer direct upload of photos. Photos can be uploaded from your computer as part of adding an observation record.

It is also possible to upload your photo to a web photo service (e.g. Flickr or Picasa), or to your own website, and then add the URL of the photo to your observation record.

Observer Smart Phone Application
to make observations of wild plants, including photos.
for Android   and   for iPhone

2012 February 7: Version 1.23 released for Android.

Define you own plant lists for use in the Observer application.

Calflora Mobile Search for Plants
a smart phone application for looking up wild plants by name or characteristics. Click on a plant name, and you will see one or two photos of the plant. Works on Android and iPhone.

Check the current location box and (courtesy of HTML5) it will limit the search to plants observed growing near wherever you are.

Photo 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.

 

Do you have a set of photos of California native plants? This application makes it possible to contribute them to Calflora simultaneously as both observations and photos. (If you have a large set of photos to contribute, please get in touch.)

Plant List Definition
to define your own plant lists to be used in the Observer Smart Phone Application, in Observation Download, and in Plant Observation Entry.
 
Certain special purpose plant lists (BAEDN Priority Weeds, Cal-IPC Priority Weeds) have been defined for general use.

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

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

My Observations
to review, edit and publish your observations.

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.
 

 
Upload a shapefile, let the server take it apart and return the data, and then assign the fields.

For line and polygon shapefiles, the geometries are stored on the server and associated with your uploaded records.

What Grows Here?
- move to an area of interest
- select criteria such as genus = Allium
- search for the local plants

Search for Plant Occurrence Records
 

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

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.

Example: Saccharum ravennae (ravennagrass) including lines and polygons from UC Davis McLaughlin Reserve.


 
Technical Notes

2012 January 21: Most Taxon Report pages have a link in the bottom right called 2011 Jepson Manual Treatment which goes directly to the Jepson eFlora page for that plant. For example, Linanthus pungens.

2011 October 4: Calflora has incorporated the Jepson Manual 2 scientific names into the Plant Name Library. Search for what has become of particular plant names with the Name Status application.

For instance, how are plants that used to be in the genus Elytrigia treated in the new Jepson Manual?
