Ecosystem engineers like the superb lyrebird significantly modify soil and litter in forest environments, which can enhance seed germination rates.
A two-year study in Victoria, Australia, assessed the effects of lyrebird engineering versus herbivory from large mammals on vegetation, showing that engineering increased germination but herbivory negatively impacted plant density and diversity.
Overall, both processes affect forest-floor vegetation, suggesting that increased seed germination due to lyrebird activity might help plants adapt and evolve over time.
