Stanislaw Timber Company owns 9,000 acres of timberland purchased in 2003 at a cost of $1,400 per acre. At the time of purchase, the land without the timber was valued at $400 per acre. In 2004, Stanislaw built fire lanes and roads, with a life of 30 years, at a cost of $84,000. Every year, Stanislaw sprays to prevent disease at a cost of $3,000 per year and spends $7,000 to maintain the fire lanes and roads. During 2005, Stanislaw selectively logged and sold 700,000 board feet of timber, of the estimated 3,500,000 board feet. In 2006, Stanislaw planted new seedlings to replace the trees cut at a cost of $100,000.
