peyote harvest regrowth

THE SCIENTIFIC RESEARCH PROGRAM

Untouched Lophophora williamsii in the regrowth study site population

Peyote post-harvest regrowth –
Control group

Summary of our observations –
after four years

Concerning data on regrowth involving multiple pups:
    1) There is not necessarily a direct 1:1 correspondence between sequential figures for individual pups within a single plant.
    2) It was not uncommon for some or all pups to be partly or entirely covered so some photos may reflect the pre-uncovery state.

    Images of the tags can be viewed via the links in the column for the tag numbers and images of the actual plants can be viewed using the links in the column headed "Number of crowns".

    A number of our tags and plants were completely buried and hence provided missing data in 2009. In 2010-2012, thanks to the use of a high powered metal detector we located all of our tags, stakes and plants unless they were totally missing from the study site.

    Images and data concerning the control group can be found below.

    The data summary for the regrowth group

    The data summary for the reharvest of the regrowth group at two year intervals

    An additional 20 plants (#201-220) were harvested during the November 2008 monitoring
to make up for what was then believed to be lost plants from the original group of 50 harvested plants.
   [The results concerning those twenty individuals. ]

Comments concerning control plant #151

In March 2010 we discovered that plant number 151 had been decapitated by passing porcine traffic. Its two broken heads were replanted by us near their tag. In a late summer visit that same year we found that one of the heads had again been kicked out of the ground and was badly shriveled. It was once again replanted.
In March of 2011 we found the head that had taken root in 2010 was quite healthy and growing whereas the shrivelled one was nowhere to be found. More interestingly the original plant #151 was located by virtue of it sending up new pups.
On 13 March 2012, neither broken crown we had replanted could be located. The original plant was still present showing new growth.
