REVIEW OF HIGHWAY PLANTING INFORMATION APPROPRIATE TO NEVADA

ROADSIDE PLANTING IN NEVADA HAS TO TAKE INTO ACCOUNT THE SEVERE AND VARIABLE CLIMATIC CONDITIONS THAT EXIST IN THE STATE'S 10 VEGETATION ZONES. AS A WHOLE THE STATE IS SUBJECT TO EXTREME DROUGHT, WITH MANY BASINS CONTAINING STRONGLY ALKALINE OR SALINE WATER. AIR TEMPERATURES VARY FROM -20 F IN THE WINTER TO OVER 100 F IN THE SUMMER. MANY OF THE SOILS ARE LOW IN AVAILABLE NUTRIENTS, AND HEAVY EXPANSIVE CLAYS IN SOME AREAS ARE UNFAVORABLE TO PLANTS REQUIRING GOOD DRAINAGE AND SOIL AERATION. STRONG AND PERSISTENT WINDS ARE NOT ONLY A SOURCE OF EROSION BUT ALSO HAVE A DELETERIOUS EFFECT ON PLANTS BY CARRYING SAND OR SNOW. THE PRESENT PUBLICATION DISCUSSES THESE FEATURES IN RELATION TO HIGHWAY CONSTRUCTION AND MAINTENANCE, PROPOSES GENERAL CRITERIA FOR HIGHWAY PLANTING IN ARID CLIMATES, DISCUSSES TYPES OF PLANTINGS FOR SPECIFIC PURPOSES (E.G., WIND SCREENING, NOISE ABATEMENT), DESCRIBES IN DETAIL THE REQUIREMENTS OF PLANTS IN THE NEVADA SETTING, REVIEWS PROGRAMS IN OTHER WESTERN STATES, MAKES GENERAL RECOMMENDATIONS OF A PROCEDURAL NATURE, AND, IN A SECTION THAT COMPRISES MOST OF THE BOOK, BREAKS DOWN PLANT SPECIES INTO PREFERRED AND NONPREFERRED CATEGORIES FOR SPECIFIC CLIMATIC CONDITIONS. THIS SECTION PROVIDES, FOR EACH SPECIES, SUCH INFORMATION AS ELEVATION, SOILS, MOISTURE REQUIREMENTS, INSECTS, DISEASES, CULTURE, PLANTING TIME, AND PLANTING TRIALS HISTORY. GENERAL AND SPECIES INDEXES ARE APPENDED, ALONG WITH A PRECIPITATION MAP OF NEVADA.
