Tapping into the vast pool of existing plant resource knowledge is the first step toward developing production systems that successfully balance ecological, economic, and cultural concerns in the newly formed extractive reserves in Acre, Brazil. Field research targeting extractive activities by women in the forest communities identified the most common species used by women, and documented specific information on the management, collection, and processing of these plants. The women demonstrate refined botanical knowledge and plant management skills, exploiting over 150 wild and domesticated species in their communities. They possess particular proficiency in processing plants, especially species used for food, spices, beverages, and medicines. Women also display a great desire to enter the market economy, and have begun to test potential market products on a small scale. As such they can play a key role in production, diversification, and development of economically valuable plant products, and ultimately in the success of the extractive reserves.
