Invasive Plants: Western North America: An Introduction To Problematic Widespread Species

This identification guide highlights invasive plants that can case economic and ecological damage to crops, range, forests, and wildlands in the West.
Most of these problematic plants are non-natives that now grow in locations beyond their known historic range. A non-native designation can refer to a plant from other continents, regions, or ecosystems. Once in a new area, these plants can establish and spread, free from their natural competitors.
Some invasive plants are also referred to as noxious weeds. The term "noxious" is a legal definition for plants that have been determined to be major problems in agricultural and rangeland ecosystems; the federal government and many states have compiled lists of "noxious" plants. Many of the weeds in this guide are listed in the regional weed-free forage standards that are intended to reduce the spread of invasive plants in natural areas through the movement of hay and mulch.
The Pocket Naturalist series is an introduction to common plants and animals and natural phenomena. Each pocket-sized, folding guide highlights up to 150 species and most feature a map highlighting prominent sanctuaries and outstanding natural attractions. Each is laminated for durability.


Waterford Press produces two major series of laminated, folded nature and travel guides -- the Pocket Naturalist "TM" and Pocket Traveler "TM."

There are currently more than 114 Pocket Naturalist "TM" guides covering national, regional, state, and city-specific nature topics including "the wildlife of...," "the birds of...," "the trees & wildflowers of..." etc. With titles for 42 of the 50 states, Waterford will have at least one Pocket Naturalist title for every U.S. state by the end of 2003.

Waterford's Pocket Traveler series consists of guides for language, city, and eco-travel, covering destinations in Latin America, Europe, Africa, and Australia.
-- The Pocket Traveler City Guides provide a synopsis of the top attractions, shopping and entertainment venues, and the rapid transit systems of some of the world's greatest cities. Getting around in a foreign city is simplified by encouraging the traveler to use public transit, and sites are referenced by both their street address and the nearest subway stop.
-- Pocket Traveler Speakeasy Guides offer a simplified language reference in 12 panels. Visual devices such as color cues, "root" phrase links, and "plain English" pronunciations enable a user with no familiarity with the language to communicate instantly on the basic, essential issues such as booking a room, purchasing tickets, and asking directions.
-- The Pocket Traveler Eco-Travel Guides introduce visitors to the nature and sites of some of the world's top eco-travel destinations, including Costa Rica, Africa, Australia, Galapagos Islands, and more.
