The CALINVASIVES Project
Calinvasives is a new database management system, fully interfaced with Calflora, providing basic and important information on the biology, ecology, epidemiology, and impacts of emergent pathogens or emergent pathogens associated with insects threatening native California ecosystems. Calinvasives is an ideal single source in which it is possible to:
To generate a page about an emergent threat not yet included in the database management system, please create a Calflora contributor account and go to the

Viewing a Pest Page
Here is an example of a Pest page: Phytophthora ramorum. The Pest page displays a map showing any available occurrence data.
Press the Map Detail link (above the map) to go to the Map Detail page for this organism. This page is intended to produce printable maps, which focus on certain areas or aspects of the distribution. For instance, you can choose to see only records within a certain span of years, or only records of a particular host plant. You can choose to see either point observations or cells. For cells, the side of a cell is selectable from 200 meters to 20 kilometers.
Viewing a Plant Pest × Host Page
Here is an example of a Plant Pest × Host page: Phytophthora ramorum on Quercus agrifolia (coast live oak).
Note that the distribution data shown on the map is a subset of the distribution data shown on the Phytophthora ramorum page; it includes only those records of P. ramorum where the host plant was Quercus agrifolia.
Adding a Pest
To add a pest, first register as a Calflora contributor. You can do this on the Calflora Home Page: press LOGIN - REGISTER in the upper right and fill out the form. It takes about a minute.
Please take a look at some examples of pests already in the system to get a sense of the style, and what kinds of information the system can display about a pest.
Once you are registered. open the Pest Editor to add an organism or a complex.
Uploading Occurrence Data
Once you have added a pest, you can upload point occurence data to show the distribution of the organism. To do so, prepare a spreadsheet with the following fields in this order:
The value of Result is either P (positive) or N (negative). The default value is P.
(Here is an example of a spreadsheet prepared in this way for
Go to the Pest Editor, select your organism, and scroll down until you see the OCCURRENCE DATASETS section. Click on Add another. Enter a name for the dataset you are about to upload, and choose a release date. (Note that name and release date can be changed later.) Then press .
A dialog box opens, starting on the [Input] tab. Copy all of the data out of your spreadsheet, paste it into the big text box, and press .
The [Preview and Upload] tab will open, and you will see your data in a table. If any of the records have errors, the error appears in the last column. The most likely errors are a missing date, or a value of latitude or longitude that is not a number.
Press . Your data will be uploaded to the database, and the [Publish] tab will open. Press if you want to keep the data, or if you want to start over.
The data you just uploaded will appear on the Pest page for your organism. All available occurrence data will be shown in red cells, where each cell represents all of the points inside of its area. (You can set the map cell resolution in meters in the OCCURRENCE DATA section.)
The Release Date attribute of an occurrence dataset
is a way of controlling when the data will be shown as
If the current date is after the release date for an
occurrence dataset, then the data will be displayed
on the map when a user has zoomed close and selected
HostPlant: If the value of the HostPlant field is resolvable to the name of a plant covered by Calflora, then that occurrence record will be cross referenced to that plant. This means that if the plant is entered as a host plant for the organism, the same point will appear on the organism map/page and on the organism X host plant map/page. For instance, if there is an occurrence record for the organism Phytophthora ramorum, and the host plant on that occurrence record is Vaccinium ovatum, then that point will be shown on both the map/page for Phytophthora ramorum and the map/page for Phytophthora ramorum X Vaccinium ovatum.
Exporting Occurrence Data
Use the Calinvasives Data Export application to export occurrence data in various formats.
