'Seed Transfer Zones' could help restore vast areas of degraded land in Brazil

Phys · · 610 words · By University

A new study led by the University of Exeter has established 48 Seed Transfer Zones in Brazil to guide the selection of native seeds for land restoration. The research aims to address climate change and biodiversity loss by aligning seed sourcing with current and future environmental conditions.

“A new study divides Brazil into 48 zones, each defined by its climate and soil conditions.”
SINGLE SOURCE
One web search result mentions identifying 48 Seed Transfer Zones (STZs) in Brazil based on climatic conditions, but the evidence provided for claim 0 specifically is generic and does not confirm the 48 zones for Brazil. The result in claim 1's evidence provides the specific number, but it's a single source.
