How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse
How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse
Aspen Bibliography
Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.
The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …

Weather And Plant-Development Data As Determinants Of Grazing Periods On Mountain Range, David F. Costello, Raymond Price
Weather And Plant-Development Data As Determinants Of Grazing Periods On Mountain Range, David F. Costello, Raymond Price
Aspen Bibliography
Fundamental in economical range-resource management is the determination of proper grazing periods. It is of prime importance to be able to establish a date in the spring when the range has produced sufficient feed to keep livestock in thrifty condition, when it is reasonably safe from excessive trampling and packing of the soil, and when the more important key forage plants have attained sufficient development to withstand grazing use. Such opening dates, as well as the time to defer and rotate grazing and to remove livestock from the range, are dependent in part on the prevailing weather conditions and on …

Grazing Periods And Forage Production On The National Forests, Arthur W. Sampson, Harry E. Malmsten
Aspen Bibliography
Stockmen in the West have always had confidence in the adequacy of the native forage crop to provide pasturage for their livestock. Indeed, under normal climatic conditions this enormous natural resource has not failed the grazier, except where it has been called upon to meet unreasonable demands. The productivity of the range has declined sharply, however, wherever the requirements of plant growth have been disregarded for many years in succession. Where there has been too early or too frequent and to heavy grazing, undue trampling, or some other unsatisfactory feature of range use, the results have been uniformly bad. Many …
Climate And Plant Growth In Certain Vegetative Associations, Arthur W. Sampson
Climate And Plant Growth In Certain Vegetative Associations, Arthur W. Sampson
Aspen Bibliography
The relation of climate to the growth and development of vegetation is of profound importance in both practical and experimental agriculture. It is extremely useful to know the cause of successful growth and establishment, or of partial success or failure, of various species in different plant associations and under widely contrasted climatic conditions. The climatic requirements of various plant types are largely responsible for the results obtained in the case of experimental seedings and plantings of most species. Once the adverse climatic factors are definitely known, failures with plants may be largely avoided by the judicious selection of sites or …
