Effects of Grazing and Shrub Management on Species Composition and Soil Properties in Patagonian Grasslands

Grasses
Historical sheep farming in the Patagonian drylands has led to reduced grass cover, soil erosion, and shrub encroachment, compromising ecosystem function.

Effectiveness of integrated shrub management and restoration techniques for rehabilitating shrub‐encroached rangelands of South Africa

Grassland Research, EarlyView.
Herbaceous plant recovery following shrub clearing and reseeding in the rangelands of Peddie, Eastern Cape of South Africa. CTL, control; CO, cutting only; CR, cutting and reseeding; UPO, uprooting only; UPR, uprooting and reseeding. Abstract Background Shrub encroachment (SE) drives rangeland degradation, threatening biodiversity and forage ...

Exploiting Differential Vegetation Phenology for Satellite-Based Mapping of Semiarid Grass Vegetation in the Southwestern United States and Northern Mexico

Remote Sensing, 2016
We developed and evaluated a methodology for subpixel discrimination and large-area mapping of the perennial warm-season (C4) grass component of vegetation cover in mixed-composition landscapes of the southwestern United States and northern Mexico.

Concentration and composition of condensed tannins in leaves from fodder trees and shrubs in Pakistan

JSFA reports, EarlyView.
Abstract Background The lack of dependable, high‐quality forage and animal feedstuffs in many areas of the world hampers livestock production. In these regions, farmers often rely on native fodder tree and shrub leaves as a forage source for their animals with little or no information available on nutritional factors of these feedstuffs.

Effect of a Trench Combined With Exclosure on Recovery of Herbaceous Biomass in Degraded Mountain Areas in Hawasa Watershed, Southern Ethiopia

Land Degradation &Development, EarlyView.
ABSTRACT The objective of this study was to evaluate the restoration of herbaceous biomass in degraded mountain lands by comparing the impact of trenches established alongside exclosures (EX‐SWC) to exclosures alone (EX). To achieve the objective, herbaceous biomass was collected from areas restored using EX‐SWC and EX over three consecutive years ...

Vegetation Structure and Diversity Under Farmer Managed Natural Regeneration: A Comparison of Silvo‐Arable and Silvo‐Pastoral Systems in Kenya

Land Degradation &Development, EarlyView.
ABSTRACT Farmer Managed Natural Regeneration (FMNR) is a low‐cost, adaptable agroforestry practice that enhances land restoration by promoting systematic integration of naturally regenerating trees within farming systems through tree selection and management.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...
