the Calflora Observer Pro Android phone application for collecting plant occurences in the field. His latest personal project is an Android word game experimenting with creating a multi-player experience from a single-player game.

Participate in the Calflora Community
We (the Calflora team
) rely on
a community of interested and engaged users.
If you are interested in wild plants in California,
you are cordially invited to join this community.
For instance, if you are aware of a plant growing wild
in some park or other location where it is not yet
shown on Calflora, we urge you to become a contributor and
to add an observation of that plant where you know it grows.
Equally important: if you notice information on Calflora
that seems wrong or incomplete, please
let us know.
If it is an observation record that does not look right
and you are a contributor, you can write a comment on the record.
We do pay attention to comments and answer emails.
In this sense, what you see on Calflora is in part the product of
the vigilance of engaged users.
Volunteers are an important part of
the ongoing quality assurance process. If you have the inclination
and a little bit of time, we would love to have your help.
Here are some particular volunteer jobs:
- Add new Great Places
- Choose plant photos for the Taxon Report pages
- For particular plants, add links to Taxon Report pages
which go to other interesting web pages about those plants
