The iNaturalist page to view, download, and add data to is posted here.

As a citizen scientist on this project you can help by: 1) Look for infected trees. Spotting their presence is relatively straightforward as the fungal infections they carry form dark stains across the tree bark near boreholes of about a millimeter in diameter (This photo ,taken with a ballpoint pen near the borehole, gives some scale to this.). 2) Take two photos. For the first photo of the infected tree make sure its leaves are clearly visible in order to aid with tree species verification. For the second photo please have a closeup shot of a borehole near a fungal stain. For the closeup shot please include a ruler or pen near the borehole to give a sense of scale. 3) Tag the image with the collection data and GPS location. Using the iNaturalist app on your phone should automatically be able to include the GPS data with the photo. If you want to upload the images later and use the web-based version of iNaturalist then you can easily extract the GPS data from the photos as described here. 4) If possible, please record the type of tree infected. If you're not sure what species of tree is in the photo you can always click on the 'ID Please' tag on the submitted images. The community at large can help with identifying the species.
