Forest Preservation

The Warden's Lodge in Bowerdene keeps the realm's woods standing. Take a commission, plant saplings in the grove the warden names, and that grove will flourish for you for the rest of the day — richer hauls and crop seeds while you chop there. Claim at the lodge for Heartwood and gold.

The commission

One commission a day, taken at the lodge. The warden names a grove you have the Woodcutting level to work and can already reach, and asks for 8 saplings planted there.

Saplings are sold at the lodge for 5 gold each and nowhere else — they can't be traded or auctioned, so a commission is always work of your own. Planting one is a short task at the grove itself; the lodge won't let you waste saplings on the wrong wood.

Claim whenever you like — the reward keeps. But an unclaimed commission blocks the next one, so the warden only ever has one job out with you at a time.

A flourishing grove

The moment the last sapling goes in, the grove flourishes for you until the day ends: +5% double yield while you chop there, and a 1 in 50 chance of turning up crop seeds with a felled tree. It follows the place, not you — walk to another wood and it waits where you left it.

Good to know

Each claimed commission counts toward your Forest Preservation tally on the highscores.
Planting trains Woodcutting like any other work.
A Yield proc while planting puts two saplings in the ground and counts both toward the commission.
Whetstones stack like any draught, and their success bonus applies to Woodcutting only — as the pack says when you hover one.
