U.S. Forest Ownership: Historic And Global Perspective, Lloyd C. Irland
U.S. Forest Ownership: Historic And Global Perspective, Lloyd C. Irland
Maine Policy Review
Mainers once enjoyed the sense that the state’s vast forested lands would forevermore be a feature of the state’s landscape and cultural heritage. However, this sensibility has been threatened by fragmentation and sprawl and rapid changes in ownership. According to Lloyd Irland, Maine is not unique. The U.S. is facing a crisis of sustainability in forests and rural communities. Irland provides a brief history of forest ownership in the U.S. and analyzes some global trends to help to explain this crisis. He suggests Mainers look to experiences elsewhere in the nation and world to come up with a new mix …
Effects Of Herbicide Application Of Foliar Morphology And Nutrient Concentrations In Mid-Rotation Pine Plantations, Prabudhda Dahal, Hal O. Liechty
Effects Of Herbicide Application Of Foliar Morphology And Nutrient Concentrations In Mid-Rotation Pine Plantations, Prabudhda Dahal, Hal O. Liechty
Journal of the Arkansas Academy of Science
Application of herbicide to reduce competing brush and hardwood species is a common silvicultural activity in young loblolly pine (Pinus taeda) stands. A reduction in competition generally increases the amount of available resources to the loblolly pine crop trees thereby increasing foliage biomass, fascicle dimensions, and foliar nutrient concentrations. To what extent herbicide application and competition control alters these foliar characteristics in mid-rotation stands has rarely been reported. The purpose of this paper is to evaluate whether the application of herbicide alters the morphology, mass, and/or nitrogen concentration of mid-rotation loblolly pine foliage. We aerially applied an imazapyr herbicide to …
Identifying The Factors Distinguishing Timber Sales On Industrial And Non-Industrial Private Forest Lands In Arkansas, Sayeed R. Mehmood, Prabudhda Dahal
Identifying The Factors Distinguishing Timber Sales On Industrial And Non-Industrial Private Forest Lands In Arkansas, Sayeed R. Mehmood, Prabudhda Dahal
Journal of the Arkansas Academy of Science
Although forests provide a wide variety of products and services, timber still continues to be the most valued forest product in the marketplace. More than two-third of the nation's forests are under private control, some are owned by industries (about 10%) while a much larger portion (about 59%) is owned by individuals. This study investigates the differences between timber sales offered by industrial and non-industrial ownerships. A test of means revealed that there is a significant difference between per hectare bid for these 2 types of sales. A logistic regression model was then estimated to identify important factors characterizing this …
