Filed under Mexico, Monarch Population Status | 2 Comments »
In the last update of the eastern monarch population (late September) we noted that it would be interesting to see how monarchs cope with the lack of nectar and water in Texas. We knew that the migration would make it through Texas (and Northern Mexico) but we didn’t know what impact the drought conditions would have on it.
Modest numbers of monarchs have already arrived at the overwintering sites in Mexico and they will continue to arrive through the end of the month. Preliminary reports indicate that the monarchs are spread out over an area of four hectares or so at this time but we expect this area to shrink in the coming weeks as the masses of monarchs become more consolidated.
Our predictions regarding the size of the overwintering monarch population still stand (visit the link above for details); official measurements will be done in late December and we will report the findings in an update after the first of the year.
