More and more countries are introducing formal requirements to prove legal harvest. Several of our key forestry trading partners—including Australia, the United States, Indonesia, Republic of Korea, Japan, Vietnam, and China—have implemented or are developing their own legislation to prevent the import or export or trans-shipment of illegally harvested timber. We export nearly 85 percent of our timber products to these countries. Third-party environmental certification has, to date, been accepted by most of our trading partners as a means of demonstrating legality. However, private certification is not a viable financial option for the majority of our smaller growers, who represent approximately 30 percent of the estate and who are supplying up to 40 percent of the harvest during the 2020s, due to the age of their forests. With the building of international efforts to ensure that traded timber products are legally sourced, we also need to ensure that we have a legal harvest assurance in place. If we do not do this, we run the risk that we no longer can export to these markets.
