If we find today that the soil is too acidic (below 4.5), how might that affect the number of species we find?
We may find a lot MORE species as most plants like acidic soil.
We may find a lot LESS species as most plants like very basic soil.
We may find LESS species as most plants will not grow well since they won't have the nutrients to grow and reproduce in very acidic soil.
There should be no measurable effect.
