NEW MEXICO ROADSIDE DEVELOPMENT PROJECT

IMPORTANT ASPECTS OF VEGETATION ESTABLISHMENT ON ROADSIDES IN ARID /AVERAGE ANNUAL RAINFALL --8.5 IN./ NEW MEXICO WERE INVESTIGATED IN THIS FOUR YEAR STUDY. GRASSES, MULCHES, FERTILIZATION, PLANT PROPAGATION, TREE AND SHRUB PLANTING TECHNIQUE AND EROSION STUDIES WERE INCLUDED IN THE PROJECT. OF 24 SPECIES OF GRASSES TESTED UNDER NURSERY CONDITIONS ONLY 5 WERE SELECTED FOR PLANTING ON THE ROADSIDE. OF THESE, ONLY TWO SPECIES OF LOVEGRASS INDICATED ADAPTABILITY FOR THE ROADSIDE ENVIRONMENT. BECAUSE OF LIMITED AVAILABILITY OF WATER NO SIGNIFICANT INCREASES IN GROWTH WERE PRODUCED AS A RESULT OF NITROGEN APPLICATIONS. DESERT WILLOW /CHILOPSIS LINEARIS/ AND APACHE PLUM /FALLUGIA PARADOXA/ ARE NATIVE SPECIES THAT GREW COMPARATIVELY WELL UNDER ROADSIDE CONDITIONS AND SHOWED ADAPTABILITY FOR EROSION CONTROL PURPOSES. TRANSPLANTING PLANTS FROM AREAS ADJACENT TO THE RIGHT-OF-WAY WAS A DISAPPOINTING OPERATION. ARID CONDITIONS RESULT IN EXTENSIVE ROOT-SYSTEMS THAT CANNOT BE SUCCESSFULLY MOWED BY CONVENTIONAL METHODS. IT WAS FOUND THAT UNTREATED CUTTINGS TAKEN FROM DORMANT PLANTS OF NATIVE SPECIES IN NOVEMBER ROOTED WELL. THE LIMITED AVAILABILITY OF NURSERY GROWN STOCK OF MANY NATIVE SPECIES SHOULD NO LONGER BE A MAJOR PROBLEM. MEDIUM SIZE GRAVEL SERVED AS AN EFFECTIVE MULCH, PROVIDING EXCELLENT MOISTURE RETENTION AND PROTECTION AGAINST EROSION. /BPR/
