Economics of Cogongrass Control in Slash Pine Forests AgEcon
Alavalapati, Janaki R.R.; Jose, Shibu; Stainback, G. Andrew; Matta, Jagannadha R.; Carter, Douglas R..
Cogonagrass (Imperata Cylindrica), an invasive weed, is a threat to slash pine forests. Using a dynamic optimization model, we estimated the impact of cogongrass on the profitability of slash pine forestry under four scenarios: no threat of cogongrass infestation; infestation is uncertain, and no control measures are taken; infestation is uncertain, but control measures are undertaken by one landowner but not the neighbors; and infestation is uncertain, and control measures are undertaken by everyone. Results indicate that annual net returns per acre under each scenario, respectively, are $25.30, $16.97, $13.89, and $17.38. Results suggest fostering a cooperative behavior among landowners is desirable.

VISITOR PREFERENCES AND VALUES FOR WATER-BASED RECREATION: A CASE STUDY OF THE OCALA NATIONAL FOREST AgEcon
Shrestha, Ram K.; Alavalapati, Janaki R.R.; Stein, Taylor V.; Carter, Douglas R.; Denny, Christine B..
We used the open-ended contingent valuation method to elicit willingnes to pay (WTP) for day visitors and extended visitors on the Ocala National Forest (ONF), Florida. A Tobit model specification was applied to account for the issues involved with censored WTP bids. The results reveal that visitors would pay more for improved recreational facilities at the ONF. In particular, our estimates show that visitors would pay $1 million for basic facilities, $1.9 million for moderate improvements, and $2.5 million for more improvements.
