Oak mast is a very important source of fall and winter food for many species of wildlife, particularly in the heavily forested portions of the state. Fluctuations in mast production can exert a strong influence on wildlife species that depend on mast crops for food, and can influence fall and winter wildlife movements.  Additionally, mast production is essential for oak regeneration and persistence in the short-term and migration of oak species in response to environmental changes over longer time scales (e.g., climate change). The Missouri Department of Conservation has conducted an annual survey of mast production since 1960.

Many factors can affect the amount of acorns produced each year. One factor that has not been greatly explored is local elevation gradients in topographically diverse areas such as the Missouri Ozarks. Managers have recently shown interest in this relationship with anecdotal evidence that acorn production differs across elevation. To explore this relationship, acorn data was used from the Missouri Ozark Forest Ecosystem Project (MOFEP) sites in Carter, Shannon, and Reynolds counties.

Rarely is redcedar managed sustainably in Missouri despite its ecological and potential economic value. There is interest in sustainably managing redcedar, but uncertainty about the best way to accomplish this goal. In order to fill this information gap, a pilot study was installed in a dense, redcedar stand on a south-aspect site in southwest Missouri to investigate the impacts of management options on redcedar growth and regeneration.

As part of a larger test of redcedar management, redcedars were planted in stands that had been clearcut. This report addresses the early performance of redcedar seedlings with respect to slope position in a clearcut in southwest Missouri.

Pin oak (Quercus palustris Muenchh.) and pecan (Carya illinoensis (Wangenh.) K. Koch) trees were planted on reforestation plots at Four Rivers Conservation Area in west-central Missouri. The study was conducted to determine survival and growth rates of the two species under different production methods and environmental variables. Production methods included direct seeding, bare root seedlings, and RPM® planting stock. Combi-nations of planting stock and species were implemented on two elevations (mounded or unmounded soils).

Eastern redcedar is an ecologically and economically valuable tree species in Missouri. However, rarely is redcedar managed sustainably. This pilot study was initiated to investigate the impacts of forest management on redcedar growth and regeneration.

There is considerable interest in restoring shortleaf pine by various agencies and private land-owners in Missouri. Given that 85% of commercial forests in the state are under private ownership, restoration efforts are not possible without the participation of private landowners. In preparation to assist private landown-ers with shortleaf pine restoration, an understanding of their interest, attitudes and motivations toward restora-tion and general forest management is necessary.

The specific objectives of this study were to:

  • Determine the characteristics of landowners in the shortleaf pine range and the extent to which they are planting and managing shortleaf pine.
  • Identify landowner reasons for restoring shortleaf pine on their land.
  • Identify landowner challenges to shortleaf pine restoration.

Detailed information on the level of wood harvested from Missouri’s forests is necessary for intelligent planning and decision making in wood procurement, forest resources management, and forest industry development. Likewise, researchers need current forest industry and industrial roundwood information for planning projects. In the spring of 2013 the Missouri Department of Conservation (MDC) undertook a detailed census of primary wood processors throughout the state, asking for information on their firms from 2012.

MDC’s Community Forestry Program advises, coordinates, and facilitates the efforts that affect Missouri’s community-owned trees. Assistance provided by MDC is targeted at local governments, arborists, non-profit organizations, and planning councils. To better understand citizen attitudes towards certain community forestry issues, such as hazard trees, topping, and urban sprawl, a survey questionnaire was mailed to randomly selected recipients in 44 selected Missouri communities. Our goal was to determine the issues citizens in these communities felt to be most pressing, the support for passage of two hypothetical ballot issues, and the knowledge level citizens have about the tree program in their community.

White Paper April, 2010

A common concern among forest managers today is how best to manage forests using prescribed fires while simultaneously minimizing carbon emissions. In light of increased public awareness concerning climate change, the need to reduce carbon emissions into the atmosphere is a top priority around the world. Therefore, research into the most optimal forest management practices that reduce carbon emissions have been conducted in various regions and contiguous forested tracts. Further, models of carbon emissions produced by various forest management practices have been developed to shed light on those that are the most suitable for sustainable management of a forest ecosystem while minimizing the release of carbon.

Forestry Division has begun a state-wide campaign focused on increasing awareness of the benefits that trees and forests provide to Missourians. To be effective, this “Trees Work” campaign’s messages must resonate with a wide variety of groups and population segments. To develop and evaluate such targeted messages, we must understand 1) the current level of awareness of tree and forest benefits, 2) which benefits are most important to Missourians, and 3) what messages are most likely to motivate people to action and what barriers prevent action toward sustainability of Missouri’s forests. The campaign is planned to last several years, so baseline research provides critical information for development and evaluation.
