Comparing benefits of tree planting vs natural colonization for future resilience of UK woodlands – New Study/Science Updates
In a new study published in the journal Evolutionary Applications, scientists from the Royal Botanic Gardens, Kew, and Forest Research, present a detailed analysis of the genetic diversity and comparative tree health of young British woodlands, revealing the pros and cons of planting versus natural colonization.
Summary
A new study in Evolutionary Applications examines the genetic diversity and health of young British woodlands, comparing planted forests to those that naturally colonize. Scientists from Kew and Forest Research found both methods have advantages and disadvantages. Planted woodlands often benefit from higher initial survival and faster growth due to carefully selected saplings. However, naturally colonized woodlands can exhibit greater genetic diversity, potentially enhancing long-term resilience to pests and diseases. The research highlights the importance of understanding the trade-offs between these reforestation strategies for optimizing woodland health and biodiversity.
