Mimms Unit encompasses 11,000 acres on the northwest edge of Marfa in Presidio County, an area that boasts some of Texas’ finest rangeland. This property is also a precious piece of the Chihuahuan Desert region, where desert grasslands are a critical ecosystem for many plants and animals, particularly migratory birds.

Dixon Ranches Mimms Unit regularly hosts field programs for volunteer groups, students and landowners. For example, the Marfa International School uses the ranch as a “Living Classroom” for its innovative science program. The Highland Soil and Water Conservation District brought area public schools to the ranch to learn about wildlife, soil and range management. Land managers have learned about our grazing system during workshops and tours with the Texas Section of the Society for Range Management and Holistic Management International.
