Evaluation Of Restoration Of Damaged Ecosystems On Soil Nematode Communities And Their Functions In The Desert Steppe Open-Pit Mining Area Of Inner Mongolia, Zhiwei W. Gao, G. D. Han, G. G. Zhang
Evaluation Of Restoration Of Damaged Ecosystems On Soil Nematode Communities And Their Functions In The Desert Steppe Open-Pit Mining Area Of Inner Mongolia, Zhiwei W. Gao, G. D. Han, G. G. Zhang
IGC Proceedings (1997-2023)
In view of the general lack of analysis of the ecological restoration effects of underground soil in the desert grassland ecological restoration projects in Inner Mongolia, this study selected the most representative open-pit quarries, open-pit iron mines and open-pit coal mines in the desert steppe. Using high-throughput sequencing technology, nematode community composition, diversity, and function were analyzed to determine the response of nematodes to different ecological restoration methods in damaged areas of coal mines. In open-pit coal mines, for slope rehabilitation, vegetation blanket restoration exhibited more favorable effects than those exhibited by vegetation bag restoration and natural restoration. For rehabilitation …
Optimising Forage Production On Degraded Lands In The Dry Tropics Through Silvopastoral Systems, P. S. Pathak
Optimising Forage Production On Degraded Lands In The Dry Tropics Through Silvopastoral Systems, P. S. Pathak
IGC Proceedings (1997-2023)
In India, 187 M ha out of a total area of 328 M ha face the problem of land degradation, mostly due to water and wind erosion. The problems are aggravated by poor land cover and increasing pressure of human and livestock populations. There is over-exploitation of the scarce resources of forage and firewood. Several techniques, including watershed based silvopastoral land use have been proposed (Patil & Pathak, 1977). Tree, grass and legume based systems have been tried after land treatment to reduce runoff and soil loss while meeting the forage needs of the livestock and firewood for cooking in …
Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup
Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup
Master's Projects and Capstones
Nearly all terrestrial plants form symbiotic relationships with mycorrhizal fungi. These beneficial soil microbes support plant health by increasing plants’ access to nutrients and water, protecting them from pathogens, improving soil properties, and more. A challenge to restoring forests on coal mined land in Appalachia is that mine soils are often degraded in a number of ways, including lacking mycorrhizal fungi, which makes mine soils difficult for trees to grow upon. Substantial improvements to coal mine reforestation success have been made since the development of the Forestry Reclamation Approach in 2005 that provides guidelines for how to create a suitable …

As climate change brings drier and more variable rainfall patterns to many arid and semi-arid regions, land managers must re-assemble appropriate plant communities for these conditions. Transcriptome sequencing can elucidate the molecular mechanisms underlying plant responses to changing environmental conditions, potentially enhancing our ability to screen suitable genotypes and species for restoration. We examined physiological and morphological traits and transcriptome sequences of coastal and inland populations of California sagebrush (Artemisia californica), a critical shrub used to restore coastal sage scrub vegetation communities, grown under low and high rainfall environments. The populations are located approximately 36 km apart but …
Capturing Genetic Variation During Ecological Restorations: An Example From Kankakee Sands In Indiana, Rebecca W. Dolan, Deborah L. Marr, Andrew Schnabel
Capturing Genetic Variation During Ecological Restorations: An Example From Kankakee Sands In Indiana, Rebecca W. Dolan, Deborah L. Marr, Andrew Schnabel
Rebecca W. Dolan
Genetic variation in populations, both natural and restored, is usually considered crucial for response to short term environmental stresses and for long term evolutionary change. To have the best chance of successful long-term survival, restored populations should reflect the extant variation found in remnants, but restored sites may suffer from genetic bottlenecks as a result of founder effects. Kankakee Sands is a large-scale restoration being conducted by The Nature Conservancy (TNC) in northwestern Indiana. Our goal was to test for loss of genetic variation in restored plant populations by comparing them with TNC’s seed source nursery and with local remnant …

Tree Thinning And Prescribed Burning Effects On Ground Flora In Arizona Ponderosa Pine Forests: A Review, Scott R. Abella
Tree Thinning And Prescribed Burning Effects On Ground Flora In Arizona Ponderosa Pine Forests: A Review, Scott R. Abella
Public Policy and Leadership Faculty Publications
Ground flora is an important response variable to monitor after tree thinning and prescribed burning treatments designed to restore Arizona ponderosa pine (Pinus ponderosa P.& C. Lawson) forests. This paper reviews published literature on the effects of thinning and burning on ground flora in Arizona ponderosa pine forests in five main categories of research: ground flora biomass, species diversity, plant community composition, population processes, and individual species ecology. Research published to date suggests that thinning and burning generally increase ground flora biomass, whereas other categories of research such as community composition and population processes have been little studied in Arizona …
