Effect & research conditions
Research costs 200 Food and 300 Coin and takes 30 seconds. The 20% bonus applies to Villagers gathering Wood from trees and Mango Groves. Blackwood Trade is researched at the Livestock Market after Selective Logging, and Ebony Exports is the next step in the chain.
Research condition
Available to Africans from the Fortress Age. Research it at Livestock Market. It requires Selective Logging.
When to research
Research when many Villagers can stay safely on Wood long enough to recover the cost, especially if the economy also plans to continue into Ebony Exports. If forests are depleted or workers need to move to other resources, the gathering bonus has less time to repay the investment.
A source-specific African Wood upgrade
Blackwood Trade raises Villager Wood gathering from trees and Mango Groves by 20%. It does not increase gathering from unrelated sources. The technology continues the African Wood line after Selective Logging, with Ebony Exports as the subsequent upgrade.
Check the forest and prerequisite first
The Fortress Age research requires Selective Logging, costs 200 Food and 300 Coin, and takes 30 seconds at a Livestock Market. The return depends on workers having access to trees or Mango Groves. Continue toward Ebony Exports only if the Wood economy remains active and the next cost fits the plan.
