I've managed two ranches low fence and two hf under Type III MLD over the past 18 years. We've always employed a biologist to handle all paperwork, permitting, aerial census, TPWD approved management plan and any other headaches. $2,500/year for him and $1,400 for the helicopter survey.
Couldn't agree more with Cattleman on everyone following the plan. It's a great program, imo.
