| 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. |

| Recreational hunting has been an attractive enterprise for some ranchers who are interested in supplementing their income from cattle. Ranchland attributes-such as parcel size, tree cover, and proximity to urban centers-are expected to influence hunters’ preferences and, thus, hunting lease payments. We estimated the effects of these attributes on hunting revenues using a hedonic model. The results reveal that trees and vegetation cover on ranchlands have a positive impact on hunting revenues, indicating opportunities for silvopasture practices. Those ranchers in Florida who maintain about 22% trees and other vegetation cover receive $16.15 acre per year from hunting leases, but doubling the cover would generate only an additional $3.20 per acre per... |

| The impact of fire risk on slash pine (Pinus elliottii) plantations managed for the joint production of carbon and timber benefits was investigated. A Hartman model for determining the optimal rotation age and Land Expectation Value (LEV) for a stand with both carbon and timber benefits was extended to include the risk of fire. Information from this model was then used to determine optimal rotation age, LEV, carbon supply and timber supply as a function of fire risk and the price of carbon. The results indicate that fire risk reduces all of these variables and this reduction is greater for higher carbon prices. These results suggest that landowner's would respond less to a carbon market when the level of fire risk is relatively high. |

| In recent years there has been increased debate about the potential for shifting the incidence of the tax system away from a variety of economic goods (i.e. employment, investment, etc...) and towards environmental bads (i.e. pollution emissions, resource extraction, etc ...). However, in spite of their apparent efficiency, economic instruments have been adopted relatively less frequently than direct regulation to mitigate environmental damages. One reason may be that some of the distributional implications of environmental tax reform have not been adequately recognized and addressed. How the costs and benefits of environmental policies are distributed in society is critical for their application since this will play a significant role in determining... |
