I collected rocks my 1st time on NR and that took me 3-4 trips around the planet, not again. Nothing for plants, artifacts, crystals, water samples and gourds(?), they do not give a % to your total, while collecting 'lost' reports in the Staging Area does?
You need to turn those in to the appropriate NPC in the area. Turning in batches grant you around 10%-12% progress.
