REVEGETATION METHODS AND CRITERIA FOR BARE AREAS FOLLOWING HIGHWAY CONSTRUCTION

METHODS AND CRITERIA FOR REVEGETATION AND STABILIZATION OF ROADSIDES IN MONTANA INVOLVE PROBLEMS OF BROAD SCOPE AND COMPLEXITY. VARIOUS FACETS OF THE ROADSIDE SEEDING PROBLEM WERE STUDIED IN SEQUENCE AT SEVERAL SITES, EACH EXPLORATION INDICATING OR SUBSTANTIATING THE PRIORITY OF STUDY NEEDS. A ROADSIDE VEGETATION SURVEY AND A CONTRACT SEEDING EVALUATION STUDY PROVIDED A BASIS FOR A SELECTION OF INITIAL STUDIES CONCERNING SEEDING AND MULCHING. THIS WORK LED DIRECTLY TO SPECIES SELECTION TESTS, OBVIOUS FERTILIZER REQUIREMENTS, AND EFFECTS OF FERTILIZER SLURRIES ON SEED GERMINATION CHARACTERISTICS. UNSATISFACTORY PERFORMANCE OF MULCHES PROMOTED TRIALS WITH EXPERIMENTAL MULCH BINDERS WHICH PROVIDED SOME UNEXPECTED ADVANTAGES. THE SENSITIVITY OF TIME OF-SEEDING UNDER SEMIARID GROWING CONDITIONS ENCOURAGED THE TESTING OF DRYLAND PLANTING INNOVATIONS WITH BOTH GRASSES AND SHRUBS, WHICH LED TO THE DEVELOPMENT OF DRYLAND PLANTING OF TUBELINGS AND SHRUBS WITHIN CONDENSATION TRAPS. THESE EXPLORATORY STUDIES INDICATE AREAS OF CONCERN WITHIN WHICH FUTURE MAINTENANCE ECONOMIES MAY BE REALIZED WITH A MINIMUM OF INVESTMENT IN TIME AND MONEY. /AUTHOR/
