Ethiopia — A first butterfly baseline shows habitat differences, but elevation is confounded with vegetation
WHAT THE EVIDENCE SAYS
A 28-day survey recorded 32 butterfly species and 2,037 individuals. Forest had the highest richness and diversity, but all three vegetation zones supported distinct assemblages and grassland contributed unique species.
WHY IT MATTERS / OUR READ
The useful result is as much methodological as biological: baseline inventories are valuable, but habitat conclusions can be overstated when vegetation zone and elevation are inseparable.
CAVEATS / UNCERTAINTY
Species accumulation curves did not reach asymptotes, sampling covered one seasonal window, and site and elevation were completely confounded. Treat this as a baseline rather than a causal test of vegetation effects.

Hamericho Mountain Forest supported distinct butterfly assemblages across forest, shrubland and grassland, with important design limits.
