It is preferable that material used on the steeper slopes of riverfronts and lake fronts should possess a deep root system which willaid in protecting the slopes against erosion. If the slopes are steep and wash badly during periods of rain such types as locust, sumacs,willows, and the matrimony vine will form a deep root system quickly.The process of naturalizing trees and shrubs on the slopes of riverbanks and lake shores is a slow one. It should never be attempted as asingle operation. The material should be young, a great percentage ofloss must be expected, and only the "survival of the fittest" rule canapply. |
