Environmental Impact Research Program. Chufa (Cyperus esculentus) Section 7.4.1, US Army Corps of Engineers Wildlife Resources Management Manual

摘要

A report on chufa (Cyperus esculentus) is provided as Section 7.4.1 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report was prepared as a guide to assist the Corps District or project biologist who may wish to establish chufa plots for wildlife on project lands. Major topics include plant description, distribution, habitat requirements, wildlife value, establishment, and maintenance. Chufa is an introduced sedge used primarily for wild turkey (Meleagris gallopavo) and waterfowl management in the Southeast. A description of the sedge and its naturalized range is given in this report. Soil, moisture, and shade requirements are specified, and the value of chufa as a wildlife food is discussed. The establishment of chufa for wild turkey and for waterfowl is described under separate headings. The method outlined for establishing upland stands includes site selection and preparation, plot design, planting instructions, and plot maintenance. Guidelines are given for establishing chufa for waterfowl by enhancing natural stands through proper management of water levels. Cautions and limitations of growing chufa are also pointed out.
