Our ability to restore rangelands is limited, and it is unknown if seedling herbivory on its own, or in interaction with other stressors, is a major contributor to restoration failure. To address this, we conducted two experiments: a No Defoliation (

Compensatory increases in net photosynthetic assimilation rates (Anet) following herbivory are well documented in adult rangeland grasses but have not been quantified in bunchgrass seedlings, which may be more sensitive to tissue loss than establishe

Weed prevention is recognized as one of the most cost-effective management strategies for invasive plants. In the field of invasive plant management increasing emphasis is being directed toward proactive management. However, land managers are still s

Prevention programs are often assumed to be the most cost-effective method for managing invasive plants. However, there is very little information available about economic and biological factors that determine the forage benefits resulting from preve

Our objective was to evaluate the cost/benefit of a single herbicide application or targeted grazing of invasive annual grasses during restoration of partially invaded sagebrush steppe ecosystems used for livestock production. The cost/benefit model

Various technologies are available for managing invasive plants and restoring desirable plants on rangelands, but acceptable long-term control and restoration can only be achieved when integrated management approaches focus on the ecological processe

One of the most challenging problems for land managers is advancing infestations of invasive weeds. Treating weeds is often really only treat- ing a symptom. A fundamental tenet of Eco- logically Based Invasive Plant Management (EBIPM) is that manage

I n ecosystems that are heavily invaded, it is common for the level of degradation to become so intense that the native plant seedbank is reduced. In these cases, active restoration that includes revegetation efforts and stress manipulations through
