Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
A chronosequence (1 to 250+ years) of 160 woody species plots was established throughout northern Missouri riparian forests to explain the influence of site hydrology and stand age on species distribution and forest ...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer ...
Utilizing on-line surveys to gather data: an application to help evaluate Missouri's interpretive programs
(University of Missouri--Columbia, 2005)
Most state and federal agencies involved in the management of natural resources offer educational programs that serve several purposes. In Missouri, the Departments of Conservation and Natural Resources play this vital ...
Spatially explicit and stochastic forest landscape model of fire disturbance and succession
(University of Missouri--Columbia, 2005)
Fire disturbance plays an important role in shaping ecosystem dynamics and vegetation patterns in many forested landscapes. This dissertation is dedicated to the modeling of fire disturbance in spatially explicit and ...
Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
As a flood-tolerant and fast-growing species, cottonwood is a promising species in flood plain and short-rotation forestry. Understanding tree growth will provide critical assistance in flood plain forest management and ...
Simulating the effects of riparian zone delineation and management practices on landscape pattern and timber production
(University of Missouri--Columbia, 2004)
Best management practices (BMPs) are essential to giving the forest manager guidelines to follow that result in the least amount of negative impact on the forest landscape and corresponding riparian areas. The purpose of ...
Modeling forest transition pathways for decision making in private forestry
(University of Missouri--Columbia, 2004)
In the Central Hardwoods Region, 90% of forested lands are privately owned and the majority of harvested hardwoods come from non-industrial private forests. However, many landowners seek little professional advice when ...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading ...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the ...
Variation in the flood tolerance of three midwestern oak species
(University of Missouri--Columbia, 2007)
Several studies on flood tolerance of hardwood seedlings have suggested ecotypes exist among seed sources related to past flooding history and soil hydrological properties of the collection site. Our study examined differences ...
Assessing the capacity for collaborative ecosystem stewardship on private forestland in the Missouri Ozarks
(University of Missouri--Columbia, 2007)
Missouri's forestland totals nearly 15 million acres and a vast majority of this area, roughly 82 percent, is controlled by more than 300 thousand nonindustrial private forest (NIPF) owners. Consequently, meaningful long-term ...
A multi-dimensional investigation into the effects of flooding on the physical, chemical and biotic properties of riparian soils
(University of Missouri--Columbia, 2008)
Understanding soil abiotic and biotic influences on ecosystem processes will enhance success of riparian restoration efforts. The goal of this research was to characterize changes in soil chemical and microbial community ...
The socioeconomic and cultural significance of food gardening in the Vladimir Region of Russia
(University of Missouri--Columbia, 2008)
Russia's family gardens currently produce over half of the country's agricultural output and represent a major sector of the country's economy, involving two thirds of the population. Despite this prominence, household ...
Estimation of total height, growth, and mortality of forest trees in Missouri
(University of Missouri--Columbia, 2005)
A model for predicting total tree height as a function of tree diameter was calibrated for twelve tree species common to the Missouri Ozarks. Model coefficients were derived from nearly 10,000 observed trees. The calibrated ...
Validating Missouri landtype associations using tree species composition, forest structure, and productivity
(University of Missouri--Columbia, 2005)
Missouri's Landtype Associations (LTAs) were delineated from 1995-1998, and are currently being used by natural resource managers, but these LTAs have never undergone a validation showing that they can encompass patterns ...
Linking ecological and social dimensions of Missouri landscapes
(University of Missouri--Columbia, 2005)
A recent study by the Brookings Institution concluded that patterns of growth in Missouri are eroding the quality of life and rural heritage, and threatening the environment. Reversing these trends will require better ...
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
Desire to restore the function of riparian forest ecosystems has become a primary objective of many land management agencies in the United States. In the eastern U.S., much emphasis has been placed on planting native ...
Overstory density and its effect on oak regeneration abundance and oak understory height growth in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2008)
This study examined how overstory density affects regeneration abundance and understory height growth in the Missouri Ozark Highlands. Data were collected on three different treatment types, no harvest management, uneven-aged ...
Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
Bottomland restoration of native hardwood species provides a variety of benefits to the environment and the landowners. However, when reforesting agricultural floodplains along the Missouri River, high soil pH often causes ...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
There is growing interest among forest and wildlife managers in the reforestation of bottomlands with mast producing hardwoods in the Lower Missouri River and Mississippi River Alluvial valleys. However, it is common for ...
