Access by other users
When a record is published, other Calflora users can see it. When a record is unpublished, nobody can see it except the person who entered it. Some contributors choose to work on certain records over time in an unpublished state, and then publish those records only when they are ready.

Records submitted via the upload application or the phone application arrive into the database in an unpublished state, and must be explicitly published by the person responsible before other users can see them.


Scientific Name
The scientific name of the plant observed. Typeahead is enabled for typical invasive plants -- type the first few letters, then choose the name from the popup list.

Note that genus is capitalized. For instance:

    Acacia dealbata
This field will accept only the full scientific name of a plant already in the database, or the word unknown. If you have alternate scientific names or other notes, please put them in the Comments field.

If you wish to enter the scientific name of a plant that is not yet in the database (for instance, a new weed), put a * (star) just in front of the plant name, as the first character in the field. You can also use * (star) to enter genus-only names. For instance, to indicate some plant in the genus Acacia, enter:



Common Name
The common name of the plant observed. Typeahead is enabled for typical invasive plants -- type the first few letters, then choose the name from the popup list.

Note that Common Name is for plant lookup only, and is not stored on the observation record.


Observation Date
Date the plant was observed, in the form YYYY-MM-DD. For example, 2009-01-15.

Press today for today's date. Press calendar to choose the date from a calendar.


The primary habitat type infested by the weed at this location.

  • Forest: Tree-dominated, generally with a closed canopy (e.g., redwood forest, eucalyptus grove)
  • Open Woodland: Tree-dominated, but with open areas between the trees (e.g., oak woodland)
  • Scrub/Shrubland: Shrub-dominated, with few or no trees (e.g., coastal scrub, chaparral)
  • Grassland / Open Field: Grass-dominated, with few to no shrubs or trees
  • Stream bank / bed: The banks or dried bed of a stream, creek or river
  • Wetland: Herbaceous-plant-dominated, with standing water at least part of the year and wetland indicator plants (e.g., cattails, rushes, pickleweed marsh, vernal pool)
  • Open Water: Pond, lake, river, estuary, etc.
  • Beach / Dune: Generally some open sand, or there would be if not infested with iceplant or European beachgrass
  • Planted (Lawn, crop, etc.): An area purposely planted for agricultural, recreational or ornamental use.

Infested Area
The area of ground covered by the weed if there were no spaces between the plants. (This area can be expressed in acres, hectares, square feet or square meters.)

Gross Area
The area of ground covered by the weed, if you drew an imaginary line around the outer boundary of the infestation. (This area can be expressed in acres, hectares, square feet or square meters.)


Canopy Closure (AKA Percent Cover)
If you drew an imaginary line around the outer boundary of the infestation, the Canopy Closure is the amount of ground actually covered by the plant, expressed as a percent.

The life stage of the plant (or majority of plants in the infestation) at time of observation.

  • Seedling / rosette: Young, non-reproductive growth
  • Bolting: When the flowering stalk begins to shoot up in plants with a basal rosette of leaves (thistles or mustards, for example)
  • Flowering: In bud or flower
  • Fruiting: Setting seed or fruit
  • Dead / skeleton: Dried/dead plant or dormant perennial
  • Leafing out: Producing new leaves (for deciduous perennial plants such as tree of heaven)
  • Mature: A perennial plant NOT in one of the above stages


The distribution of the plant across the landscape.


The land owner, manager, or steward. If an infestation covers land with multiple owners, please choose the one with the most infested land. For infestations on private land, please have the landowner's permission


If a specimen was collected, the name of the herbarium where it is stored.


Location Description
A brief description of where the weed is. Please include landmarks and/or directions to the site.


Anything else you would like to report about the weed or site, such as associated plant species.


Latitude and Longitude
The center of the infestation in decimal latitude and longitude, NAD83 datum (WGS84). (This datum is available on most GPS units and used by some recent maps.)


The person who observed the infestation. If you are adding an observation, the observer will be yourself.


For records added through this application, the value of Source is the institution with which the Observer is affiliated, if any. If the Observer is affiliated with the Bay Area Early Detection Network, the value of Source should include "BAEDN."

For other records, the Source is the name of the institution which contributed the record to Calflora.


If this record is part of a particular data collection project, put the name of the project here.


Location Accuracy
An estimate of the accuracy of the location coordinates, expressed as an area in square meters. For instance, if the location accuracy is set to 100 square meters, then the idea is that the real point is somewhere within that 100 square meter area.

When you specify location by picking a point on the map, location accuracy depends on the zoom level of the map when the record is first entered.

When GPS equipment is used to find a point, the location accuracy will depend on the quality of the equipment, conditions at the time the point was taken, as well as any methods employed to correct or verify the coordinates.

To specify location accuracy, press the Specify link. In the panel that opens, you can choose an accuracy range, such as 100 square meters. Or, you can enter the radius of a circle around the point, and calculate location accuracy as the area of that circle.

Number of Plants
Either an estimated range of the number of plants at this location, or an exact count. If you know the exact count, please enter it by clicking in the text box and typing over the value. Otherwise, choose a range from the drop down list.

Special values:

    1: exactly one plant.

    0: no plants; absent.

    1+: at least one plant. This is the default value for older records.
