Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
of log grade through the harvest cycle shows the highest increments at Cordoba region. Dendrometric variables such as heartwood, sapwood, and diameter and crown height are good estimators of tree volume, taper and branch modeling....
Developing a stand density module in LANDIS to improve simulation realism of stand dynamics
(University of Missouri--Columbia, 2009)
Long-term landscape modeling is dependent on various forest dynamics including large-scale disturbances, environmental effects, land management and stand-scale succession. The stand density module was designed for LANDIS ...
Analysis of landscape characteristics surrounding deer vehicle accidents in St. Louis County, Missouri
(University of Missouri--Columbia, 2008)
Increased suburbanization of rural landscapes is leading to a greater number of human animal interactions. One of the most dangerous and costly of these interactions is collisions between vehicles and white-tailed deer (Odocoileus virginianus...
Detection and modeling of bat species occupancy at multiple scales across a forested landscape in southeastern Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Populations of forest dwelling bats have been in decline in recent years, and have therefore become increasing foci in forestry research efforts. Difficulty in bat species...
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 management, and even...
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 structure. Stand age was found...
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 effects of prescribed...
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
bottomland agricultural fields. These afforestation practices most often consist of planting bare-root tree seedlings of a select number of hardmast species and managing vegetation with a number of pre- and postemergent herbicides, or planting a perennial...
Evaluation of the Private Forestland Ownership Paracelization and its effects on the forest landscape in the southeastern Missouri Ozarks
(University of Missouri--Columbia, 2005)
This study investigates the impacts of the forestland ownership parcelization on species composition, age structure and spatial pattern of the forest landscape. First, a computer model was developed to create ownership ...
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 (Odocoileus virginianus Zimm...
Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
simulation model, was applied to simulation of the cottonwood growth in a flood plain area in central Missouri. The key characteristics of the LIGNUM model are the linkage between tree spatial structure and physiological function. L-system was adopted...
Ferns as a forest farming crop: effects of light levels on growth and frond quality of selected speicies with potential in Missouri
(University of Missouri--Columbia, 2006)
In Missouri 11.3 million acres of commercial forests are privately owned. The vast majority is under very little - if any - management. Agroforestry, specifically forest farming, has the potential to provide producers an opportunity to put...
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 bottomland hardwood...
