Lophophora williamsii in habitat in San Luís Potosí.
    We found a small population located not too far from the L. koehresii we had just visited (half a kilometer) but growing in different habitat.

More evidence of plant habitat destruction was found, with the peyote being dug up along with their roots, but this time the root harvesting poachers forgot several of the plundered plants.

Interestingly the poachers went specifically for the L. williamsii and ignored the L. koehresii growing between the highway and the ridge where the L. williamsii was growing. This suggests that the poachers could tell them apart and were catering to a market that requires mescaline-containing plants rather than harvesting cacti for horticultural purposes.
