MOFEP is actually an integrated program of research studies conducted by dozens of scientists and technicians across the same nine forest landscapes. Each part of the MOFEP study, whether it deals with birds or herpetofauna or genetics or fungal communities or volume growth or some other aspect of the forest, requires detailed information about the composition and structure of the forest vegetation and about physical site charactertstics. That information provides a basic descrtption of the forest and is necessary to interpret future results in an ecological context.MOFEP will outlive the professional careers of the scientists and technicians who are now conducting research and who are intimately familiar with the study sites and forest conditions. Over time, as trees are hruvested, the character of the study sites will change dramatically. Consequently, at the outset of this long-term expertment, it is essential to thoroughly document features of the physical landscape and the condition of the associated forest vegetation.This report provides a detailed descrtption of the MOFEP study area and of the forest vegetation from 1991 through 1995, the pertod of study establishment and pretreatment data collection. We expect this report will be a prtncipal reference for those involved with the Missourt Ozark Forest Ecosystem Project and for those who will interpret and apply the results of that research. This report will also provide essential documentation for those investigators who will add new studies to MOFEP in the future. In combination, the chapters in this report provide the most detailed descrtption ever assembled for an upland Ozark forest. In fact, there are few other databases anywhere that descrtbe forest conditions in comparable detail for such a large area. In addition to serving as essential documentation for the MOFEP research, the matertal in this report provides a valuable baseline of forest conditions that can be used to compare and contrast findings from oth...
As forest managers in the Midwest focus more attention toward understanding and maintaining ecosystem processes, greater emphasis is being placed on the role of snags and down wood in providing wildlife habitat, cycling nutrients, and maintaining continuity in forest structure following harvest. We measured five remnant old-growth hardwood tracts and six mature, second-growth, hardwood tracts in Missouri and compared findings concerning (1) the volume of down wood and (2) the number and size distribution of snags (i.e., standing dead trees). Volume of down wood ≥ 10 cm in diameter averaged 36 m³/ha on the old-growth tracts, double the 18 m³/ha mean volume for the second-growth sites. This difference in volume was concentrated in pieces of down wood with diameters larger than 20 cm; below diameters of 20 cm the number of pieces of down wood by diameter class was similar for the old-growth and second-growth sites. On the old-growth sites, the mean basal area of snags ≥ 10 cm dbh was 1.9 m²/ha. This was approximately 1.5 times greater than the mean basal area of snags on the second-growth sites. The number of snags ≥ 10 cm dbh on the old growth sites was approximately 9% pf the number of live trees on those sites. The corresponding value for second-growth sites was 8%. On both the old-growth and second-growth sites, the number of snags and the number of live trees by dbh class followed a negative exponential (reverse-J) form. Frequency distributions for the number of snags by dbh class closely followed those for live trees on the same sites. These results provide managers with general guidelines for the quantity of down wood likely to be found in mature second-growth forests and old-growth forests. We also provide some provisional rules of thumb for estimating the density and size distribution of snags from values observed for live trees in the same stand. North. J. Appl. For. 14(4):165-172.
