You need to make sure that you have photos of all of the area habitats that you have listed on your site and, if you don't, the LPA will ask you to resubmit the metric sheet (sometimes the LPA may even request additional photos of a particular habitat parcel. This is easily done).
Step One
Open your project and go to the "Onsite habitats" section and click on "Baseline habitat parcels"
Step Two (skip if you are putting in trees or hedgerows)
Look at the list of habitats that you already have. Select the parcel that the LPA would like to see more photos of. When selected, pick the third yellow hexagon to open the Image Uploader
Simply drag the additional photos into the designated box (please note that there is a maximum of two photos per parcel).
