Harvester Risk Atlas ranks which wild medicinal plants of the Philippines need help first, shows where they grow, and says how sure we are.

What's in the final version

  • A ranking with honest uncertainty: 29 native medicinal plants scored on rarity (corrected for where botanists actually searched), harvest harm and habitat pressure, then re-run 2,000 times. Every plant gets a range, not one number. Tongkat ali ranks 2nd of 29, anywhere from 1st to 5th.
  • Safe maps: plants appear only as broad hexagons (~250 km²), never exact spots, so the atlas can't lead collectors to them.
  • New: Seasons: play the year and watch where each plant is recorded month by month, and when observers saw it in flower or fruit, through the dry and wet seasons. Every month is weighed against how many people were out looking.
  • New: checked against expert sources: 50 of 51 names matched in World Flora Online, and plants compared with Co's Digital Flora of the Philippines, built on the work of botanist Leonardo L. Co. For tongkat ali it agrees (native, DENR Endangered) and points to places to survey next: Mindoro, Homonhon and Bucas Grande.
  • A survey plan: two thirds of the land next to known records (2,992 of 4,542 areas) has barely been searched.

For research and education. Not medical advice. Harvest traits come from published sources and still await expert review, so feedback from botanists, rangers and harvesters is very welcome. Leave a comment!
