Termite mounds preserve bird diversity pockets even where savanna became farmland

Mozambique field counts find that tiny structures within a landscape can matter as much as the land-cover label.

System: Savanna / grassland / agriculture

WHAT THE EVIDENCE SAYS

Researchers surveyed birds at 160 dry-season sites in Acacia savanna, saline grassland and farms. Termite-mound vegetation had higher bird richness and density than the surrounding matrix in all land uses, including agriculture. Mound bird communities resembled each other across land uses, while some natural-savanna matrix specialists disappeared from farms.

WHY IT MATTERS / OUR READ

Land cover alone hides microhabitat structure. Land managers should survey and conserve vegetated mounds and other ecological islands, but that does not replace the natural grassland matrix. Protecting one habitat element is not equivalent to preserving the entire community.

CAVEATS / UNCERTAINTY

Observational, dry-season point counts; no experimental mound retention/removal or population viability test. Mound vegetation does not fully compensate for savanna conversion.
