Ant species (Hymenoptera: Formicidae) of the Jornada

Important Statistics

Number of species in North America: 751
Number of species on the Jornada Experimental Range: 74
Number of new species recently described on the Jornada Experimental Range: 4


JRN is an exceptionally species rich site (at about 10% of the entire North American fauna). This is probably due to the intensity of work here but also due to the geographic position of the area and the diversity of ant habitats.

Creosotebush-dominated (Larrea tridentata) communities, especially on the Summerford bajada, are the most species rich habitats in JRN. This plant community type is also the source of several newly described species.
