ANNUAL REPORT OF PHREATOPHYTE ACTIVITIES, 1964,
Abstract
Objectives of the programs are: (1) to find the most economical means of controlling saltcedar and other phreatophytes in areas of critical water shortage; (2) replacement with vegetation having lower water requirements and preferably with economic value; and (3) management procedures which will assure the survival of the replacement vegetation. Funds spent in the past year and programed for next year are shown. Research contracts have been negotiated with the U. S. Geological Survey and universities of Arizona and Nevada. At Denver, saltcedar (Tamarix pentandra) plants are greenhouse cultured and used as test specimens for foliar applied herbicides. Root samples were analyzed for carbohydrate content to correlate with herbicide effect and growth factors. Helicopter herbicide spraying was performed on 420 acres of saltcedar around Rye Patch Reservoir located north of Lovelock, Nevada. Water measurements are being made in a prototype area located between Bernardo and San Acacia, New Mexico, on the Middle Rio Grande Project. Over 6,000 acres of phreatophytes have been cleared and changes in water use for this area will be determined. (Author)
