Rainfall or Price Variability: What Determines Rangeland Management Decisions? A Simulation-Optimization Approach to South African Savannas [PDF]
Savannas cover the greater part of Africa and Australia and almost half of South America and contribute to the livelihoods of more than 350 million people.

Restoration Ecology, EarlyView.Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

ON THE CHOICE BETWEEN THE STOCKING RATE AND TIME IN RANGE MANAGEMENT [PDF]
A long standing question in range management concerns the relative importance of the stocking rate versus the length of time during which animals graze a particular rangeland.

Restoration Ecology, EarlyView.Abstract Introduction Globally, livestock grazing is a key driver of vegetation degradation in arid rangelands. This degradation tends to be most severe near artificial water points which are focal points for livestock activity. Conservation reserves have been established on former rangelands; however, the timeframes for vegetation recovery following ...

Restoration Ecology, EarlyView.Restoration increasingly operates in rapidly transforming landscapes shaped by human‐driven global change, where historical reference states no longer represent achievable or even desirable targets. Yet, ecological restoration and conservation management still rely on composition‐based definitions of ecosystem integrity that assume stable reference ...

Invasive Weeds, Wildfire, and Rancher Decision Making in the Great Basin [PDF]
In this article, a numerical stochastic dynamic programming model (SDP) is developed to characterize the decision problem of a rancher operating on rangelands in northern Nevada that are affected by invasive annual grasses and wildfire.

Cutting, herbicide, and fire: a case study for managing woody plants in tallgrass prairies
Restoration Ecology, EarlyView.Abstract Introduction The removal of clonal and resprouting woody plants expanding into mesic grasslands like tallgrass prairies can be expensive based on the types of treatments applied and subsequent retreatments. Objective We aimed to determine how combined herbicide application, mechanical treatments, and annual prescribed fire influenced grassland

LAND USE IN THE AUSTRALIAN RANGELANDS [PDF]
This paper reviews pastoral lease arrangements across Australia and considers the extent to which these affect the emergence of non-pastoral land uses. Some 44 per cent of Australia is made up of pastoral leases.

Restoration Ecology, EarlyView.Abstract Introduction Restoring native plant diversity in crested wheatgrass (Agropyron cristatum)‐dominated rangelands is a persistent challenge in ecological restoration across western North America. Dense, long‐lived stands of this exotic grass suppress native seedling recruitment, hinder habitat restoration, and reduce ecosystem resilience ...
