Evaluating Productivity of Southern Agroforestry for Fiber, Biofuels, and Wildlife Habitat

Gordon, Henry Gill 14 August 2015 (has links)
Wildlife habitat values associated with agroforestry systems in Mississippi are not fully understood. Landscape matrix changes resulting in close location of various agricultural and tree crops can provide habitat more suitable for use by game wildlife. This study examined the feasibility of improving habitat value by adopting agroforestry alley cropping practices. A completely randomized block design was utilized to ascertain production values for two different even-aged crop trees, shortleaf pine (Pinus echinata Mill.) and loblolly pine (Pinus taeda L.), and four different agricultural crops, corn (Zea mays L.), switchgrass (Panicum virgatum L.), grain sorghum (Sorghum bicolor L.), and soybeans (Glycine max L.). Breeding bird surveys and camera surveys were used to quantify wildlife use and determine habitat improvement produced by this agroforestry management. If agroforestry land management improves wildlife habitat quality so hunters are willing to pay higher premiums, landowners can generate additional economic return from hunting leases.

Understanding Participation in Wildlife Conservation Programs on Private Lands

Sorice, Michael G. 14 January 2010 (has links)
One major lesson derived from the implementation of the Endangered Species Act (ESA) over the past 30 years is that direct regulation is not the only nor the optimal way to protect endangered species on working lands because of an undue burden imposed on private landowners. The role of a voluntary conservation program is to rearrange incentives so that society bears the cost rather than the landowner. Employing a survey research methodology, I used theories of reasoned action and random choice to explore landowners? stated preferences for conservation programs. I found landowners? stated interest in compensation programs to be moderate at best. For those willing to consider programs involving endangered species, associating land management requirements for species conservation with direct benefits to the landowner is important, but perhaps not as important as ensuring that the program provides adequate financial incentives, consideration of the term of the program, and a level of certainty regarding the landowner?s future obligations under the ESA. Landowners are not a homogenous group. I identified two classes of landowners according to preferences for program structure. One group was highly sensitive to program structure, aside from financial incentives, while the other was likely to participate if adequately compensated with financial and technical assistance. These differences related to opinions on endangered species protection and dependence on their land for income. Voluntary incentive programs increasingly are a popular tool to maintain and enhance conservation; however, these programs are only successful insofar as landowners choose to enroll. This research demonstrates that improving recovery efforts on private lands requires program administrators to have a more complete understanding of landowners? views on endangered species and conservation programs in general, as well as their motivations for owning and operating their land. By doing so, programs with broader appeal and greater efficacy can be designed and implemented.
