A SYSTEMATIC CATALOGING AND EVALUATION OF PLANT MATERIALS FOR HIGHWAY USE

PROCEDURES ARE DESCRIBED FOR SELECTIONG, EVALUATIONG AND CATALOGING 267 SPECIES OF PLANTS CONSIDERED SUITABLE FOR THE CLIMATIC AND SOIL CONDITIONS IN GEORGIA. OF THE TOTAL NUMBER OF PLANTS LISTED 102 ARE TREES AND 165 ARE SHRUBS, VINES AND GROUND COVER. VARIOUS IMPORTANT FACTORS CONCERNING PHYSICAL CHARACTERISTICS AND SITE AND CLIMATIC REQUIREMENTS FOR THESE PLANTS WERE INCORPORATED INTO A COMPUTER STORAGE AND RETRIEVAL SYSTEM DESIGNED FOR USE BY THE LANDSCAPE ARCHITECT AS A TOOL TO FACILITATE TRADITIONAL MEANS FOR SPECIES SELECTION. DETAILED DESCRIPTIONS ARE GIVEN OF PLANTINGS MADE ON THE ATHENS BYPASS TO TEST A LIMITED NUMBER OF SPECIES SELECTED. ALSO TESTED ALONG THIS HIGHWAY WAS THE CHANGE IN VEGETATION PRODUCED BY A LIMITATION OF MOWING. THE RESEARCHERS REPORT THAT AFTER TWO YEARS THE APPEARANCE OF VOLUNTEER GROWTH HAS EFFECTIVELY BLENDED THE ROADSIDE WITH THE ADJACENT LANDSCAPE. IN ORDER TO DETERMINE OPTIMUM FERTILIZER ADDITIONS TO BACKFILL MATERIAL FOR NEW PLANTINGS, RATES FROM 0 TO 45 POUNDS OF 4-12-12 PER CUBIC YARD OF TOPSOIL WERE TESTED ON THREE SPECIES OF NATIVE PLANTS. DATA SHOWED THAT 2 TO 4 POUNDS WERE MOST BENEFICIAL FOR SURVIVAL AND ESTABLISHMENT. SEVERAL DIFFICULT-TO- PROPAGATE NATIVE PLANTS (INKBERRY, WAX MYRTLE AND PINXTERBLOOM) WERE GROWN FROM CUTTINGS TO DEMONSTRATE THE FEASIBILITY OF PRODUCING THESE PLANTS FOR USE ON ROADSIDE AREAS./BPR/
