ESTABLISHMENT OF ROADSIDE VEGETATION ALONG ARIZONA HIGHWAYS

THIS REPORT LISTS AND, IN FACT, DESCRIBES SPECIES OF NATIVE WOODY AND HERBACEOUS PLANTS THAT HAVE A POTENTIAL FOR ROADSIDE USE IN THE ARID REGIONS OF THE SOUTHWEST. INCLUDED ARE DESCRIPTIONS OF TECHNIQUES USEFUL IN EFFECTIVELY PROPOGATING AND ESTABLISHING MANY OF THE SPECIES NAMED BY DIRECT SEEDING AND ASEXUALLY. SEED COLLECTION DATES, TREATMENT AND CULTURAL PRACTICES ARE INDICATED FOR A NUMBER OF SPECIES. SOAKING MEXICAN PALO VERDE SEED IN BOILING WATER PRIOR TO DIRECT SEEDING CONTRIBUTED TO 70 PERCENT GERMINATION. THE USE OF PEAGRAVEL AND CRUSHED CINDERS WERE FOUND TO BE EFFECTIVE ADDITIVES IN MATERIAL USED FOR BACKFILLING PLANT HOLES, PROBABLY FOR THE REASON THAT WATER PERCOLATED MORE FREELY. COMPOST GIN-TRASH MIXED WITH SOIL WAS AS GOOD AS PEAT MOSS-MANURE MIXTURE WHEN USED AS BACKFILL IN PLANT HOLES. WHERE THE USE OF EQUIPMENT IS FEASIBLE, IT IS DESIRABLE TO SCARIFY THE SURFACE PRIOR TO SEEDING GRASS. TESTS DEMONSTRATED THAT PLANT GROWTH AND SURVIVAL WERE BENEFITTED BY HEAVY PRUNING, WATERING, FERTILIZATION AND THE USE OF ANTI-DESICCANTS. MULCHES OF STRAW/ASPHALT WERE MORE EFFECTIVE THAN KNIT-NET, SOIL-SET, TROY-TURF AND STRANDEX IN CONTROLLING EROSION AND SIMULATING THE PRODUCTION OF GRASS GROWTH. /BPR/
