G90-968 Nebraska\u27s Forest Resources: Acreages and Ownership
This guide describes the forest types found in Nebraska and lists acreages by ownerships.
Nebraska\u27s forest resources are very diverse and represent a unique combination of eastern hardwood, western coniferous, and northern boreal forests. Species in Nebraska hardwood forests include bur oak, red oak, silver maple, green ash, cottonwood, black willow, hackberry, black walnut, American basswood, boxelder, American elm, honeylocust, hickories and mulberry. In addition, eastern redcedar (a conifer) is found throughout the eastern hardwood forests. Conifer forests primarily contain ponderosa pine and Rocky Mountain juniper. The boreal forests contain a mixture of several of the above species and paper birch. All three of these forest ecosystems converge in the Niobrara River valley, the only such occurrence in the nation.
The three main forest types of Nebraska are elm-ash-cottonwood, oak-hickory, and ponderosa pine

Distinct high-T transitions in underdoped BaKFeAs
In contrast to the simultaneous structural and magnetic first order phase
transition previously reported, our detailed investigation on an
underdoped BaKFeAs single crystal unambiguously
revealed that the transitions are not concomitant. The tetragonal (:
I4/mmm) - orthorhombic (: Fmmm) structural transition occurs at
110 K, followed by an adjacent antiferromagnetic (AFM) transition
at 102 K. Hysteresis and coexistence of the and
phases over a finite temperature range observed in our NMR
experiments confirm the first order character of the structural transition and
provide evidence that both and are strongly correlated. Our
data also show that superconductivity (SC) develops in the phase
below = 20 K and coexists with long range AFM. This new observation,
, firmly establishes another similarity between the hole-doped
BaFeAs via K substitution and the electron-doped iron-arsenide
superconductors.Comment: 4 pages, 3 figure
Efficient Irrigation of Trees and Shrubs
In Utah, urban landscape irrigation accounts for 50-75% of the annual municipal water use, and much of it is applied in excess of the plant’s needs. This excess is a tremendous resource waste and the overspray causes substantial damage to hardscape (i.e., decks, patios, fountains, decorative concrete, etc.). Scheduling irrigation according to landscape plant water needs can reduce excess water use. In addition to conserving water, proper irrigation can encourage deeper root growth and healthier, more drought tolerant landscapes
