POLLEN AND MACROFLORAL ANALYSES AT ABIQUIU RESERVOIR, NEW MEXICO

Summary

Pollen and macrofloral analysis was undertaken at four sites in the

Abiquiu Reservoir Multiple Resource Area in north-central New Mexico. The

vegetation in the Abiquiu area varies from short-grass prairie to

pinyon/juniper woodland, depending largely on elevation, slope exposure, and

soils. Common vegetation within this area includes Pinus edulis (pinyon

pine), Juniperus monosperma (one-seeded juniper), Graminae (grasses),

Gutierrezia sarothrae (snakeweed), Chrysothamnus nauseosus (rabbitbrush),

Atriplex canascens (four-wing saltbush), Xanthium sacaratum (cockle-bur),

Artemisia spp. (sagebrush), Lupinus aduncus (lupine), Helianthus spp.

(sunflower), Yucca glauca (yucca), and Opuntia spp. (prickly pear cactus).

The major source of water for the area is the Rio Chama, which has its

headwaters in the San Juan Mountains of southern Colorado. Smaller,

ephemeral drainages are noted in arroyos closer to the archaeological sites

studied here.
