The Hidden Factor in Restoration Success: Why Seed Quality Matters
Dr. Athanase Mukuralinda of CIFOR-ICRAF Rwanda emphasizes that high-quality tree seeds are essential for effective landscape restoration, challenging the misconception that any seed suffices. Poor-quality seeds result in weak trees, undermining restoration efforts for decades. In East Africa, particularly Kenya and Rwanda, restoration is often dominated by fast-growing exotic species due to established supply systems, while native species lack similar research and breeding investment despite being better suited for resilient ecosystems. The Quality Tree Seed (QTS) for Africa project aims to strengthen seed value chains by improving links between seed source custodians, collectors, and growers. Experts highlight the critical importance of genetic diversity, recommending seed collection from at least 20 to 30 unrelated trees to ensure adequate variation for drought tolerance and pest resistance. Without proper documentation and diverse sourcing, natural variation is lost, limiting ecological complexity. Restoring biodiversity requires moving beyond simple tree cover increases to rebuilding diverse native assemblages that reflect local ecological characters. The article underscores the need for incentives for seed source custodians and rigorous record-keeping to support long-term ecological health and successful restoration outcomes in the region.
