The Observation Search application lets you search for georeferenced observations of wild plants and see them on a map. It also show photos associated with observations. There is also a Place Name Search application to help find a particular location. |

editor: Open Plant Observation Entry on this record. location-closeup: Open the Plant Distribution application showing a close up view of the record location. It will show the polygon associated with this record, if there is one, and any nearby observations of the same plant. comment (Calflora): Open the detail page for this record showing comments if any. If you are signed into Calflora you can add a new comment. This also works on CCH2 records.

SEARCH CRITERIA | |||||||||||||
Which Records are Excluded?
Scientific Name:
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.
Other Data Sources:
By default, a search from this application will
only
consider records contributed directly to Calflora.
Open
Photos: Choose records with photos 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. 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 April 15, 2019 is written as 2019-04-15. If you enter 2019-05-20 as the end date, the result will include records that were entered on or before 2019-05-20. If you put the same date in both Start Date and End Date, the results will only include records entered on that date. County include surveys/checklists: By default, survey and checklist records are not included in the results. Check this box if you want them to be included. Location Description 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.
MORE SEARCH CRITERIA For additional search criteria, open ![]() 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 particular phenology.
Location Quality: HIGH - MEDIUM - LOW.
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. Click on the view link to see an illustrated version of the plant list.

Indexed After, Before: Use one, or the other, or both of these criteria to bracket the Index Date (date added to Calflora) of records you are interested in. Dates are entered in the format YYYY-MM-DD so that April 15, 2023 is written as 2023-04-15. Source: The source organization responsible for collecting the record.

History Filter:
A history stack is a way of organizing
multiple records concerning the condition of a single patch over time.
In a history stack, all of the records concerning the patch are linked back to the earliest, or root, record.
When a history filter option has been chosen, a single record will be returned for
each stack.
only the most recent:
A single record (the most recent) will be returned for each history stack. 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. When a history stack is not available, the record ID appears in the Most Recent column. (When there is only one record of a population, that record is both the earliest and the most recent.)
only reference records: Number of Plants:
at least one: (the default value) 1 or more plants were reported.
zero: 0 plants were reported within a certain area. any: Any value. include questionable records: Some observation records have been identified as questionable by Calflora users. By default, these are not included in the results. Check this box if you want them to be included. Documentation:
How this record is documented.

DOWNLOAD RESULTS
Note that the Location Quality field is included in all downloads. If the value of Location Quality is high, the plant really was seen at the specified coordinates. If the value is medium or low, however, the coordinates indicate the general area in which the plant was found, and not a specific location. These records are useful for landscape level analysis of plant distribution.
Source and Citation should be included in any subsequent use of any downloaded record. For CCH records, the value of Citation is, for example:
Consortium of California Herbaria [CCH]. 2023. Specimen data from CCH contributing herbaria.
Retrieved from Calflora https://www.calflora.org/ Oct 01, 2023.
The value of Source is the abbreviated name of the herbarium. | |||||||||||||
