Biodiversity Plan
In 2022 San Isidro Ranch came under the management and direction of biologist Ben Koeth’s intensive management plan. To improve genetic diversity across the entire ranch, two additional 10-acre, predator-proof soft pens were constructed in 2023 as far from the current breeder pens as possible. Typical rack whitetail deer genetics have been introduced within the last three years to our breeder pens from 7F whitetails, Mag Creek, Jerry Savoy & Mike Mullen whitetail herds. We are currently utilizing roughly 400 head of deer to improve deer genetics on the entire management unit.
The current extensive whitetail breeding program within San Isidro consists of a 4,800-acre, game-fenced home pasture, 2,300-acre game-fenced Agua Verde pasture, 1,100-acre gamefenced Tortuga pasture (bowhunting), along with a separate 200-acre, predator-proof axis deer enclosure.
Ranch personnel maintain a very aggressive predator program to enhance fawn survival rates and increase gamebird population rate. More than 100 miles of enhanced roadwork has been constructed with 200,000 feet of various poly water line deployed for better water distribution throughout.
