The Observation Hotline application
lets you search for georeferenced observations of wild plants and see them on a map.
It also show photos associated with observations.
If you are having any trouble using this application, please contact Calflora support.
To use the application, click on the
map in an area of interest ,
zoom in, and press .
If you want to qualify what observations are returned,
enter some criteria, such as Plant Status = native.
to limit the search to the current map area.
To find all records in a particular park,
The results appear simultaneously as points
on the map and in a table below the map.
On the map,
indicates a checklist;
indicates a line or polygon; and
indicates a quad (for certain plants in certain areas, only quad-level data is available).
For a point observation , press location-closeup to see a close up view of the record location in the Plant Distribution application, including any nearby observations of the same plant. For a shape observation , press shape-closeup to see a close up view of the record location including the shape (line or polygon).
This application can show at most 2500 observation simultaneously. If a particular search produces more, the application will only show the first 2500.
Choosing Which Columns to Display:
Typeahead enabled. Type the first few letters of the plant
you are looking for, and then choose it from the list.
Typeahead also works with Common Name.
(To see exactly which plant names are included for any particular plant, go to the Taxon Report for the plant, and look at the list of Alternate Names in the Name Status section. See Name Status Help for an explanation of how Calflora tracks accepted and alternate names.)
A plant name is referred to as a parent when
the plant has subspecies or varieties, but they are not present in the name.
So for instance,
Plant List: To limit your search to certain specific plants, choose a plant list. Look for already defined plant lists with the Plant List Definition application, or define your own.
Other Data Sources:
By default, a search from this application will
consider records contributed directly to Calflora.
records with photos: Check this box if you only want to see records that have photos. Some records have more than one photo, and only the first one is shown in the results -- press DETAIL to see all of the photos for an observation.
Natural Status = wild: This is an implied search criterion. This application only shows records of plants growing wild.
MORE SEARCH CRITERIA
For additional search criteria, open Tools and check Advanced Form.
Start Date, End Date: Use one, or the other, or both of these criteria to bracket the Observation Date of records you are interested in. Dates are entered in the format YYYY-MM-DD so that February 20, 2017 is written as 2017-2-20. If you enter 2017-2-20 as the end date, the result will include records that were entered on or before 2017-2-20. If you put the same date in both Start Date and End Date, the results will only include records entered on that date.
Source: The source organization responsible for collecting the record.
Location: Some observation records have useful information in the Location Description field. Enter a short phrase to find any records that contain that phrase in the Location Description field.
Collection: Some contributors use this field as a way of grouping diverse observation records.
Phenology: Some contributors specify the phenology (for instance, Flowering) of the plant when they enter a record. Use this criterion to find records with a certain phenology.
include checklists: By default, checklist records are included in the results. Uncheck this box if you do not want checklist records to be included.
History Filter: This criterion has two options:
When this option has been chosen, two columns appear at the beginning of the result set: Root and Most Recent. When historical information is available about a population, the Root record will be the oldest, and the Most Recent record will be the newest. Click on either one to view it in Plant Observation Entry.
When historical information is not available about a population, the record ID appears in the Root column. (When there is only one record of a population, that record is both the earliest and the most recent.) In this way, the record number in the Root column serves as a unique identifier of a population.
Searching within a Background Polygon:
There are many background map layers available.
If you select one of the following layers, you can
search within the selected background polygon:
