Terraformation Emphasizes Broad Genetic Diversity in Reforestation Efforts

Terraformation, a global forest restoration company, has underscored the critical importance of collecting seeds from a wide array of parent trees to ensure robust genetic diversity in reforestation projects. This practice aims to cultivate resilient ecosystems capable of adapting to environmental challenges and climate change. The company's approach highlights a key principle in ecological restoration: the necessity of genetic variation within tree species.

"Field collection teams often spread their harvest across many parent trees to capture a fuller slice of genetic diversity," Terraformation stated in a recent social media post.

This strategy aligns with scientific findings that demonstrate how genetic diversity within tree populations significantly enhances ecosystem productivity and resilience. Research indicates that both species diversity and genetic diversity contribute to increased functional diversity and beneficial trophic feedbacks, such as reduced herbivory and healthier soil fungal interactions. Forests with greater genetic variation are better equipped to withstand diseases and adapt to changing conditions.

Terraformation is actively involved in promoting best practices for seed collection and storage, including modular off-grid seed banks. The company, alongside partners like CIFOR-ICRAF and Botanic Gardens Conservation International (BGCI), participates in training initiatives for non-governmental organizations on effective tree-growing techniques. A central message from these trainings emphasizes the need to source seeds from widely-spaced, unrelated mother trees to maximize genetic variation.

Experts warn that low genetic diversity can leave tree populations vulnerable, citing examples like Eucalyptus in Ethiopia, where narrow genetic bases have led to widespread disease susceptibility. Best practices for seed collection, as taught in these programs, recommend gathering seeds from at least 50 individual trees per population and from as many diverse populations as possible. This meticulous approach ensures that newly planted forests possess the inherent variability needed to thrive and contribute to long-term ecological health.
