Integrar la restauración activa en un plan de tratamiento de especies invasoras mediante la siembra o plantación de especies nativas que puedan suprimir competitivamente a un invasor puede ayudar a mejorar los resultados del manejo de malezas. Esto ocurre porque las plantas nativas pueden tener rasgos (métodos de acceso a recursos) que se superponen con los invasores, restringiendo a estos últimos de aprovechar recursos como la luz y el espacio. Sin embargo, la eficacia de este enfoque suele estar modificada por la disponibilidad de agua. Esto se debe a que las plantas pueden responder a cambios en la disponibilidad de agua modificando rasgos, como la densidad y tamaño de las raíces (biomasa), afectando posteriormente la magnitud en la que pueden competir con los invasores (Potts et al., 2019). Identificar rasgos de especies nativas que sean competitivas contra especies invasoras en sistemas de tierras secas con disponibilidad variable de agua puede ayudar a mejorar los resultados del control de malezas.

This handbook is meant to guide ranchers who are navigating the appeal procedures in either the Forest Service (USFS), housed in the United States Department of Agriculture (USDA), or the Bureau of Land Management (BLM), housed in the Department of the Interior (DOI). It does not substitute for an attorney, but it does provide a comprehensive view of the appeals process, as well as helpful practice tips. The handbook is divided into two sections: 1) a general overview of USFS and BLM administrative appeals with practice tips, and 2) a detailed breakdown of the step-by-step procedures in reference to the applicable regulations. This handbook is meant to be used wherever disputes arise where grazing permits are held or applied for on federal land. The processes discussed here also will apply when a federal agency takes an official action implemented through an official decision, such as a change in permitted livestock numbers.

Growers of organic produce in the Southwestern United States face many challenges, including variation in water and temperature, and exposure to insects and disease. As a result, smallholder organic farmers are increasingly relying on soil additives such as compost tea that improve product quality, use less water, deter pests, and reduce reliance on chemical additives (Diver, 2002). But what exactly is compost tea? Do the benefits of using compost tea outweigh any concerns? For example, can it contain pathogens, and if so, do applicators have to worry about coming into contact with pathogens? This publication provides facts about making compost tea, and reviews both the benefits and potential disadvantages to help smallholder farmers to make educated decisions regarding the use of compost tea.

The plant nursery business is complex and requires knowledge about the technical aspects of growing plants and managing a business. This publication is an introduction for those interested in starting their own wholesale nursery business. Different types of production systems - container and field production- are discussed as well as the types of plants typically grown in Southwest nurseries. Starting a business involves many decisions that will culminate in the development of a business plan. Resources for new producers include national, regional, and local trade organizations. A worksheet with questions is included to help future operators consider whether they want to start a new wholesale production nursery. Publication AZ1393 Revised 07/2017. Originally published 2006
