We are interested in developing a freely available system for enabling Citizen Science activities geared towards preserving our natural environment. To this end, we are asking individuals with GPS-enabled mobile phones to contribute to this effort by taking geo-tagged photos and sending them to us to place on the map and alert the rangers of the spread of habitat-destroying plants.
