Practical Guidebook for the Identification and Control of Invasive Aquatic and Wetland Plants in the San Francisco Bay-Delta Regions.

摘要

Plants from around the world are invading our lakes, ponds, streams, sloughs, bays and wetlands. Some of these invasions cause serious economic and ecological problems: marinas get clogged with water hyacinthstream sides get choked with ivy and tamarisk native plants and animals become threatened or endangered. Local efforts can greatly help solve these problems. These guidelines are designed to help identify, prevent, and control the most serious plant invasions. A recurrent theme in this guidebook is that prevention and early intervention is by far the best way to control invasive plants. Invasive plants often establish themselves and flourish while those people who could have identified the fledgling invasion and made a critical early intervention stand idle, because they lack familiarity with the plants, control techniques, and the trouble that lies ahead if the invasion is allowed to continue. This guidebooks goal is to provide you with information to take action against non-native plant invasions. Early detection of invasions can save vast amounts of labor and money. Prudent land managers and their staff will be familiar with all of these species, make control plans for existing invasions, and actively look for new arrivals.
