Stopping to Rest
Using data contributed by Journey North volunteers, Dr. Andy Davis analyzed the characteristics of roost sites:
"Ninety-seven percent of roosts were reported on trees; most were in pines and conifers, maples, oaks, pecans, and willows. Conifers and maples were used most often in northern flyway regions, while pecans and oaks were more-frequently used in southern regions. Roosts in southern Texas were associated primarily with grasslands, but this was not the case elsewhere. Considering the large variety of tree types used and the diversity of landcover types around roost sites, monarchs appear highly-adaptable in terms of roost site selection."
