      The refuge manages approximately 2, acres of bottomland forest and 1, acres of reforested bottomland hardwoods. Forested land on Holla Bend consists of land that was not cleared for agriculture during the Refuge’s initial development stages. These areas are portions of the old river channel and the outwash flats immediately adjacent to it. Crown Diameters Crown diameters calculated using the formulae from Table 1 are shown in Table 2. Yellow-poplar SI 70 and red maplelblack cherry have the smallest crowns, while yellow-poplar SI 80 and beech have the largest. It is inter- esting to note that yellow-poplar SI 80 has the largest crowns for trees over 16 inches d.b.h. However, yellow-.

    Bottomland Hardwood Forests • Periodically flooded stands of mature river-bottom trees – Baldassarre and Bolen • Bottomland hardwood forests (BHF) are forested, alluvial wetlands occupying broad floodplain areas that flank large river systems – Louisiana conservation of habitats and species .   Bottomland hardwood forests typically have distinct ecological zones at different elevations and flood frequencies. These zones are the result of an active river cutting its banks and forming new land (Putnam ). The soil which erodes from the bank is often deposited on the inside bend downstream on what is referred to as a Point Bar.

    Growth Assumptions by Species • Three species: Red oak, White oak, and Ash • Growth to the 2-inch class in 8, 10, 12, and 15 years • Two species specific growth rates with four starting ages at the 2” diameter over the development of the stand. • 8 possible scenarios for each species. Trees bottomland hardwood sites were examined, early May , for signs and symptoms of wood decay fungi, and for insect damage, ostensibly present before the hurricane, which may have predisposed trees to windthrow or breaks in the bole or top.

The Relationship of Bole Diameters and Crown Widths of Seven Bottomland Hardwood Species John K. Francis SUMMARY Diameters, heights, and eight crown radii per tree were measured on 75 individuals from each of seven bottomland hardwood species in Mississippi.

hydrology is the driving factor of a bottomland hardwood. The distribution of bottomland tree species across a site is determined by individual species’ tolerance of certain hydrologic regimes (as defined by very small topographical changes in the landscape).

Thus, a complete understanding of the hydrology (existing and/or target) is. The linear model predicting maximum crown radius for all trees combined fit the data poorly (R2 = ).

Crown model fits showed only moderate improvements when the data were modeled by species, crown class, and inventory measurement protocol, highlighting the variability of Caribbean forest tree crowns within and between species.

critical species-site relationships. Bottomland hardwoods are one of the lowest in elevation and the wettest types of hardwood forests. They are generally found along the edges of lakes and rivers and in sinkholes. Bottomland forests represent a transition between drier upland hardwood forest.

The Janka hardness test measures the force required to embed a inch steel ball to half its diameter in wood. It is one of the best measures of the ability of a wood species to withstand denting and wear.
