What Is Yosemite National Park Doing about Forest Pests?
It is much easier to prevent the introduction of a forest pest than it is to control an infestation after it has been introduced. Early detection is also important in managing a spread. Park managers are conducting aerial surveys, monitoring traps and forest health, identifying potential for introduction of non-native insects and diseases, and educating the public in order to prevent any introductions from occurring. How Can Visitors Help Prevent the Spread of Forest Pests? • Don’t transport firewood outside a 50-mile radius of location of procurement: Forest pests don’t stop at the park border, and they can cause serious problems when they spread to wild areas. Use local firewood, leave unused wood behind when you go home, and burn firewood where you bought it. • Don’t bring outside plant materials into the park: It might seem attractive to brighten your campsite with a supermarket azalea, or, if you live in the park, to plant a row of rhododendrons from a nursery in front of your cab
