The following is a list of twelve basic requirements for establishing a sustainable ranching enterprise in Texas and other range states and regions:

- Necessary input in rangeland -- either desert, prairie, savanna, or forest type

Comment - The equivalent of approximately 10 to 15 acres of mid-grass rangeland in good to excellent ecological condition is required to maintain one animal unit on a year-round, permanent basis. More acres are required when the rangeland is either desert shrub or short-grass prairie, and when range conditions are poor to fair. Fewer acres are required when the rangeland is tall-grass prairie.
- Necessary input in foundation breeding stock for operating a closed breeding program

Comments:
- A minimum of approximately 500 head of mature breeding stock is required to operate a genetically viable closed breeding program.

- Most suitable type breeding stock for a low-input range operation are small to medium size animals that are heavy muscled and have low to medium milking ability.

- Necessary input in outside fencing

Comment - There are three main reasons for having good outside fencing:
- Preventing loss of cattle due to drifting

- Preventing exposing the herd to disease

- Preventing waste of valuable pasture as well as valuable semen from superior bulls on another rancher's cattle.

- Necessary input in cross-fencing

Comments
- The required amount of cross-fencing is determined by the ranch's rotational grazing plan requirements, size of pastures, number of contemporary herd groups, and topographical nature of the land.

- The purpose for cross-fencing is controlling the day-to-day grazing of each animal in the rancher's herd and keeping contemporary herd groups separated for breeding, nutrition, and evaluation purposes.

- The only time a substantial input in cross-fencing is not required is when sufficient numbers of specially trained cowboys on horseback are used to control the day-to-day grazing of the rancher's cattle.

- It's important to note that when cowboys are not used to manage the grazing of the rancher's cattle, bottom-land areas with deep soil and up-land areas with shallow soil must be kept separated by cross-fencing.

- Necessary input in personnel (managers, cowboys, cooks, etc.) to handle the day-to-day operation of the ranch

- Necessary input in living necessities -- i.e., housing, energy, food, water, etc. -- for ranch owners, employees, and their families

- Necessary input in livestock water and watering points in each pasture and holding pen

- Necessary input in horses, saddles, and tack for doing daily cowboy work

- Necessary input in pens and equipment for holding, separating, working, palpating, weighing, and loading cattle

- Necessary input in tools, equipment, and supplies for implementing herd health practices

- Necessary input in tools, equipment, and supplies for managing herd nutrition

- Necessary input in tools, equipment, and supplies for accomplishing the following important work:

- plowing and maintaining fire lanes

- conducting prescribed burns

- building and maintaining barns, fences, corrals, loading chutes, cattle scales, feed troughs, roads, dams, bridges, gates, and other ranch infrastructure

- managing weeds and brush in fence lines and pastures.

Closing comment - It should be noted that assimilating the required input for establishing and operating a sustainable ranch can be accomplished either on an one large-size operation (independent) basis, or on a many small-size operations (cooperative) basis.
