POINTS

ICON PALETTE
To view the locations of a plant in the result list on the map, you have a choice of various colored icons. The default icon is a blue point:
A palette is a set of plant - icon assignments. As you choose icons to display various plants, you are implicitly making a custom palette. Custom palettes can be saved and used again. You can also choose one of three predefined palletes:

NATIVE A convenience palette for displaying observations differentiated by nativity.

Press display next to native, and the application will read points for all native plants in the result list, and show them on the map using a blue point icon.

Press display next to non-native, and the application will show points of non-native plants using a red point icon.

STATUS A convenience palette for displaying observations differentiated by status: rare, native, non-native or invasive.
LIFEFORM A convenience palette for displaying observations differentiated by lifeform.
 
custom For any plant shown in the results, press the record count, select a colored icon to use for that plant and press display points. The application will read points for that plant in the selected area and show them on the map using the selected icon.

The application keeps a list of all of the plant - icon assignments you make in this way. To see this list, press Plants with Icons:

: By going through the process of assigning icons to plants, you are defining a custom palette, and can use it again. If you move to a different area on the map and press , the points for all plants with icons will be read for the new area and displayed on the map.

Use the Palette Again: To save the current palette (your list of plant - icon assignments), press My Palettes.

  • Enter a name into the
      Save the current palette as:
    text box, and press .

  • During a subsequent session with this application, you can select it from the
      Use a previously saved palette
    drop down. Then press , and points for all the plants in the palette will be read and displayed on the map.

When you save a palette in this way, you own it and are the only one who can change it. However, other people can use it if you give it to them in a URL as described above. See the EXAMPLES below.

INDICATIONS of LOCATION QUALITY
For records with a high location quality, the point on the the map indicates a specific location -- if the plant is still alive, you may be able to find it by going to that location. For other records, the point indicates just the general area in which the plant was found, and not a specific location.

If a record has a medium or low location quality, it is displayed on the map with a white halo around it. In the graphic, the blue point on left has a high location quality, and the point on the right has a medium location quality.


If a record is obscured, then the point appears at the center of the quarter quad in which the plant was found. The quarter quad itself is displayed as a blue rectangle.

LOCATION

Find a Location in California:
Enter the name of a place in California you are interested in. You will see a list of all matching place names statewide, along with the county for each one. When you choose one of the matching place names, the map will jump there and open an InfoWindow over the exact location.

TOOLS

LOCATION PROFILE
Check this box to see elevation, climate and soil factors of the current map cursor location .

Illustrated Plant List   (printable)
The interactive version of this page does not print very nicely (the header and the map are fixed, which means that they repeat on each printed page).

After you have an interesting result showing, press this link to go to a printable Illustrated Plant List of the plants in your results.

Observation Search at this location .
Once you have search results, press this link to run an equivalent search in the Observation Search application. Where What Grows Here? can show a summary of plants in an area, Observation Search can show all observation records in the same area. This works for a selected background area (eg. a park), or for a user defined search polygon.

Click on Streams to see rivers and creeks on the map. If you are zoomed way out, you will only see the longest rivers. As you zoom in, the shorter streams appear.

When you check Stream names, a stream icon will appear at the end of each creek or river. When you click on the icon, you see the name of the creek or river, and the name of the stream that the creek or river flows into.

For instance, in Monterey County, the icon for the creek called Arroyo Seco appears at the end of the Arroyo Seco, where it flows into the Salinas River. When you click on the icon an info window pops up describing the junction:
Arroyo Seco / Salinas River
The course of the stream itself -- the Arroyo Seco -- is highlighted in blue. The course of the downstream creek or river -- the Salinas River -- is highlighted in green.

Uncheck Stream names to clear the map of all stream icons and all stream course highlighting.

If you move to a different location on the map or change zoom level, and would like to see stream name icons at the new location, press the refresh button .

What Grows Here? on Mobile
When you use What Grows Here? on a mobile device with a narrow screen, all of the controls at the top of the page collapse to the left. The map appears on top of the other controls. Use the map to choose your location and zoom level, and then touch MAP to get it out of the way so that you can see the plants.

Because of the screen width, only one photo per plant is shown.

If you want to see the plants in one long list (instead of grouped by lifeform), open RESULTS and uncheck Group by Lifeform.

Viewing your search in the field:

Once you have done a search, and set up the screen just the way you want it (eg. with the map not showing, and the plants appearing in one long list), press again so that your choices wil be included in the URL. Now you need to arrange for your search to be easily findable later when you are in the field.

Using Chrome on an Android device, there are three ways to save your search. Touch the Chrome options menu icon in the upper right.

  1. Touch the star to bookmark the current URL.
  2. Or, touch Share... and then Gmail to email the URL to yourself.
  3. Or, touch Add to Home screen and then give your search a name, such as Plants in Van Damme SP. A new icon will appear on your home screen. When you touch the icon, you will go right back to your search in Chrome.
Chrome will cache the plant photos. At some point when you have good connectivity, scroll through all the photos to give the browser a chance to cache them -- then they will be available when you go back to this search later.

Example Searches

Commercially available, low water tolerant native grasses in the Paso Robles area. A plant is included in the results only if there are at least two records of the plant in the search area. (To find commercially available low water native grasses appropriate for your area, start with this search, and move the location.)

All plants in Andrew Molera State Park, Monterey County. A plant is included in the results only if there are at least two records of the plant in the search area.

Native plants in the McKay Cove Waterfall Watershed (immediately south of Big Sur, including Julia Pfeiffer Burns State Park and Slate Hot Springs). This search looks for records with MEDIUM or better location quality, and includes plants in the results if there are at least three records in the search area. The format is set to photo, so that the results appear as an illustrated plant list.

Arctostaphylos species in an arbitrary area of the northern Sierra foothills east of Chico. The search area is a user defined polygon.

Common Oaks of Calfornia, starting in an arbitrary area of the northern Sierra foothills east of Chico. This example illustrates the use of a custom palette (Common Oaks) as a search technique. If you start with this view, then move to a different location and press , the application will load points in the new location for the twelve species of oak included in this custom palette.

Seven widespread Southern California invasive plants, starting in the Santa Monica Mountains. This example shows the use of a custom palette to show the proximity of these plants to one another.

Native Asclepias species (milkweeds), starting near Redding.

Generating a County Level Regional Flora
1. Click on LAYERS (above the map on the right) to see the menu of background layers.

2. Inside the LAYERS menu, click on Region to see all of the region background layers. Click on County to select the county background layer. When County is selected, county boundaries appear on the map, and when you click on the map, the name of the county appears below the map. (Note that this only works inside of California.)

3. Select your county by clicking on the map. The name of your county will appear below the map. For instance, if you clicked on the town of Paso Robles, San Luis Obispo County will appear below the map.

4. Open AREA and check in selected background . This will restrict the search to plants found within the selected county.

5. Open RESULTS and set   Minimum records / plant   to   3 records. This will eliminate any plants for which there are fewer than 3 observations in the county.

6. Press . The total number of plants found appears below, as well as the number of plants in each lifeform.

You can also add additional criteria to reduce the number of plants found. For instance, to find only native plants, open PLANT FILTER and set Status to native.

7. To see the results as an Illustrated Plant List, open TOOLS and click Printable version of this page. On the Illustrated Plant List page, you may choose to group the plants by family, show the bloom period for each plant, or show three photos for each plant.

8. What Grows Here? searches can be shared. For instance, here is a list of native plants observed in San Francisco County created by following the steps above:

(Hint: to get a similar flora for a different county, open the San Francisco search above, click on the map in a different county, and press .)

FREQUENTLY ASKED QUESTIONS
Q: Is there a way that I can see all points for the matching plants immediately, without having to click through the plants one-by-one?
    A: Yes, here are two ways:

    1. Open the POINTS panel. The default ICON PALETTE is called "NATIVE".
        Press display next to native to see points for all native plants.
        Press display next to non-native to see points for all non-native plants.

    2. Open TOOLS and press the Observation Search link. This will run almost the same search on Observation Search, and show a point for each matching record.
Q: For one plant in the search results, it says 14 records, but when I ask to see points for that plant, I only see 9. Why is the count different?
    A: This kind of discrepancy usually happens because quad level data is included in the search for plants (for instance, quad level records of rare plants from the CNPS Inventory), but not included when you ask to see points for the plant.
Q: Why would I use this application instead of Observation Search or Plant Distribution? What kinds of search is each application best suited for?
    A: Observation Search is good for seeing all observations in a relatively small area. It will show the photos attached to each observation. You can limit the results by date, contributor, etc.

    Plant Distribution is good for seeing the statewide distribution of a single plant. It is also good for looking at a very close up view of a single record -- it will show lines and polygons if any are available.

    What Grows Here? will show a list of plants in a given area. By the use of colored icons, it is also good for juxtaposing the point distributions of two or more plants.

RELEASE NOTES

v. 3.78 July, 2021

    When points are displayed on the map:
    • If the record has a medium or low location quality, it is displayed with a white halo around it. The halo is easier to see when the map is in Satellite mode.
    • If a record is obscured, then the point appears at the center of the quarter quad in which the plant was found. The quarter quad itself is displayed as a blue rectangle.
    This display style emphasizes that for certain records, the point indicates a general area in which the plant was found, but not a specific location.

v. 3.74 March, 2021

  • On mobile devices, your current location is shown (and updated in real time) by a blue dot. You can also click the “Pan to my location” button in the upper right corner of the map to re-center the map to your current location.
  • If your search returns only a small number of results, the results are not automatically grouped by lifeform.
