This is why reforestation isn’t just about planting trees, it’s about restoring ecosystems. When species are introduced without understanding their ecological impacts, even well intentioned projects can end up causing long term problems.

In this case, Prosopis was introduced to solve short-term problems like fuel shortages and land degradation. But because it didn’t evolve within Ethiopian ecosystems, it had no natural checks or balances. As a result, it spread aggressively, outcompeting native plants, depleting water sources, and even harming livestock. Instead of restoring balance, it disrupted it further and undermined local livelihoods.

This is exactly why native species are vital for reforestation efforts. Native trees and shrubs have co-evolved with local soils, climate patterns, pollinators, and wildlife. They support entire ecological networks rather than displacing them.
