A statistical approach for predicting grassland degradation in disturbance-driven landscapes [PDF]

2015 8th International Workshop on the Analysis of Multitemporal Remote Sensing Images (Multi-Temp), 2015
The relationship between fire and long-term trends in tallgrass prairie vegetation was assessed at Fort Riley and Konza Prairie Biological Station (KPBS) in Kansas. Linear trends of surface greenness were previously estimated using BFAST and MODIS MOD13Q1 NDVI composite images from 2001 to 2010.

Theory and application of no-tillage reseeding in degraded grasslands [PDF]

Chinese Science Bulletin, 2020
There are 400 million hectares of grasslands in China, accounting for about 40.7% of the Chinese territory, which provide fundamental ecological and economic benefits. However, more than 90% of this grassland ecosystem is threatened by degradation. This leads to the loss of biodiversity and a decrease in ecosystem functions, such as productivity, soil ...

Beyond grassland degradation: Pathways to resilience for pastoralist households in alpine grassland ecosystems

Journal of Environmental Management
Sustaining the development of rural and pastoral communities' hinges on livelihood resilience. Pastoralist household resilience relies on resource availability and decision-making abilities. Despite extensive studies on pastoralist livelihoods, a significant knowledge gap remains in understanding the nuanced adaptive capacities of diverse households ...

Restoration prospects for Heitutan degraded grassland in the Sanjiangyuan [PDF]

Journal of Mountain Science, 2013
Abstract In many ecosystems ungulates have coexisted with grasslands over long periods of time. However, high densities of grazing animals may change the floristic and structural characteristics of vegetation, reduce biodiversity, and increase soil erosion, potentially triggering abrupt and rapid changes in ecosystem condition.
