Sugar maple is becoming abundant in the understory on better quality oak sites. It competes with oak in the understory for light, water and nutrients. Use this publication to learn more about chemically controlling sugar maple.
In 1990, this study was initiated to accomplish the following objectives. First, baseline data were collected and several silvicultural options were implemented for future analysis. Second, a risk assessment model was developed and selected. Third, management guidelines were formulated based upon an analysis of site, stand, and individual-tree variables, as well as dendrochronological data.
Treeshelters are the round or square tubes that are placed over seedlings or seed to enhance growth and survival. This study designed to quantify the advantages of treeshelters when used on black walnut seedlings.

Natural rainfall usually supplies enough moisture to sustain trees without artificial watering, but during a prolonged drought, watering can help to reduce the effects of stress.
The forest health program monitors pest populations to ensure forest health concerns are incorporated into the management of state and private forests.
Forest Health Monitoring (FHM) is a national program designed to determine the status, changes, and trends in indicators of forest conditions on an annual basis.
Our mobile society can slip and slide to a crawl when a Missouri winter arrives. Chemicals used to melt ice and snow can mean safer traveling for cars and people, but can also mean real trouble for plants and soils.
Aspect, the direction that a stand faces, is an important topographic characteristic affecting species distribution and productivity in many forests. Use this publication to learn more about aspect.
Tree diameter growth differs among species, among trees of different crown and size classes, and among stands of different stocking levels. Use this publication to learn more about MOFEP and quantifying diameter growth in Missour Ozark forests.
Girard Form Class is a measure of taper of the first 16-foot log in a tree. It is widely used in the United States to adjust log volume estimates for trees with different taper.
The environmental conditions of bottomlands pose many challenges for reforestation and forest management. Use this publication to learn more about these challenges.
Large numbers of northern red, southern red, black and scarlet oaks are declining and dying in southern Missouri and northern Arkansas. This document explains the reasons for this decline.

Information is provided to inform you of the symptoms of Sycamore anthracnose and the action you should take if your trees are affected by the disease.
Arthropods can double or triple the decomposition rate of forest leaves through their feeding activity. They also are an important part of the forest food chain, because they can concentrate proteins and minerals needed by vertebrate predators
Oak regeneration failures in bottomland crop fields are largely a result of the low competitiveness of small oak seedlings on sites that are capable of producing tremendous herbaceous biomass in one summer.
Some injured trees can be treated and repaired to maintain their health and value to your home. Others should be removed. This guide contains tips that will help you make the right decisions for your trees.
Severe weather in locations across the state can cause major tree damage. The tree care decisions made in the wake of such an event can have a long lasting impact.
Corridors of trees growing along streams are called riparian woodlands. Managing these wetlands can provide food, cover and travel lanes for wildlife and provide wood products for the landowner.
This collaborative effort of the USDA Forest Service Northeastern Area, Missouri Department of Conservation, and Indiana, Iowa and Illinois Departments of Natural Resources on forest health issues of regional interest.
The International Society of Arboriculture is a worldwide professional organization dedicated to fostering a greater appreciation for trees and to promoting research, technology, and the professional practice of arboriculture.
utch elm disease is a classic example of the catastrophic devastation that can occur when an exotic pathogen is introduced into a previously unexposed population of trees with little or no genetic resistance. The disease has eliminated most of the majestic American elms in the urban setting and continues to kill trees each year.
Introduction: Hawthorn and quince rusts spend part of their life cycle on rosaceous hosts such as hawthorn, flowering crabapple and apple, and another portion on junipers. These rusts can significantly impact hawthorn production in the nursery, especially in locations where large populations of native junipers (the alternate host) are nearby.
The pine wilt disease was identified for the first time in the United States in Columbia, Missouri in 1979. This initial report was followed by confirmation of pine wilt in southeast Kansas also during 1979. Since the first report, nematode assays have located the pinewood nematode in much of the eastern third of Kansas indicating a westward movement is occurring.
The Missouri Consulting Foresters Association (MCFA), is an organization of technically trained professional foresters that each provide competent forest management advice or assistance to landowners.
The Missouri Forestkeepers Network was launched in 1996 to develop a group of dedicated and informed volunteers working to protect, sustain and enhance Missouri's forest resources through monitoring, advocacy, and education.
This bulletin is for landscape professionals, plant health specialists, homeowners and other persons interested in trees, shrubs, ground covers, and herbaceous plants in the landscape. It's purpose is to serve as a resource about plant health management information.
This pagecontains information about how communities and individuals can save damaged trees after violent storms. All articles and artwork are downloadable for reprint.
Brown-spot needle blight, caused by Scirrhia acicola (Dearn.) Siggers, delays growth and causes mortality of longleaf pine (Pinus palustris Mill.). Brown spot reduces total annual growth of southern pines by more than 16 million cubic feet (0.453 million cubic meters) of timber.
Forest Health Monitoring (FHM) is a national program designed to determine the status, changes, and trends in indicators of forest condition on an annual basis. FHM covers all forested lands through a partnership involving USDA Forest Service, State Foresters, and other state and federal agencies and academic groups.
Anthracnose is a very common springtime disease affecting many different shade trees. Ash, oak, and maple are among the most severely affected. The name - Anthracnose - is given to a variety of shade tree fungi. These fungi cause similar looking leaf spots, and can also cause leaf distortion and defoliation.
This series of slides shows woodland owners how to grow black walnut trees in natural stands and plantations for timber, nuts, and agroforestry. Covers uses for walnut, where it grows, designing plantations, site preparation and weed control, planting techniques, thinning, pruning, and pest management.
The Missouri Tree-Ring Laboratory is a forestry research facility on the campus of the University of Missouri-Columbia dedicated to the study of tree rings.
