I could still use some more plant parts. With the lakes losing their water, I've a feeling the number of invasive species is on the rise. I need more numbers to back up my theory, however.
Excellent. Keep bringing me more plant parts if you find any. <This quest is repeatable up to Honored reputation.>
Upon completion of this quest you will gain:
If you do no other quests for the Cenarion Expedition, it will take 24 turn-ins to get to Honored (22 for Humans). Therefore you never need to stockpile more than 240 Unidentified Plant Parts for any single character.
