Landslides are caused by soil erosion and heavy rainfall. If your property has any slopes, it's important to check for signs of erosion so you can avoid the risk of causing a landslide. Here are three ways you can prevent erosion damage and landslides in your own yard:
An abundance of deep-rooted vegetation is the best natural defense against soil erosion. If you don't already have trees or shrubs in your yard, consider planting some to strengthen the ground. Opt for evergreens like Douglas fir or shore pine for trees with strong, deep root systems. Shrubs like rosemary work well in combination with trees to prevent erosion and require relatively little watering to thrive.
If you already have trees and shrubs on your property, keep them well-maintained. Water the trees regularly as needed depending on their individual growth habits, and clear away dead or diseased trees to prevent debris buildup.
Growing trees and shrubs on sloped land can be tricky, but cover crops are an excellent way to protect against erosion with little hassle. Choose plants that are native to your area to promote a healthy ecosystem and ensure they thrive in your climate conditions. Some great options for cover crops are cereal grains like ryegrass, wheat and barley. Other favorites for erosion-prevention are clover, winter peas and mustard varieties.
Bare areas in your yard are susceptible to erosion, but you don't have to plant over every inch to make a difference. Mulch is an excellent option for preventing soil erosion because it helps maintain an ideal moisture balance for the soil. At the same time, mulch will benefit surrounding plants and trees by preventing pests, weeds and damage from heavy rainfall.
Using a combination of these three methods will keep your property healthy and reduce both soil erosion and your risk of landslides.
Born in San Pedro, California, as a first generation Croatian, I graduated from California State University at Long Beach with a degree in Mathematics and Chemistry and then earned a teaching credential from San Francisco State University. In 1960 I married native San Franciscan Jim Brown. Jim, was a high school teacher before becoming the owner/chef of La Lanterna Restaurant in Kentfield from 1985-1992. He is now retired. I combined substitute teaching in Marin County with the rearing of our four children, all of whom are grown and have settled in Marin. I became intrigued with the world of homes when we acted as the general contractors in building our own home in Woodacre and another home in the San Geronimo Valley. I began to work the carpet business, and became licensed to sell real estate in 1976. I was an associate realtor with other companies before becoming an independent broker and opening my own office in downtown Larkspur in 1991.
