Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck Apr 2021

Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck

Student Research Symposium

One of the threats currently facing Great Salt Lake wetlands is Phragmites australis. Its rapid expansion since 1987 has displaced native vegetation and changed the composition of plant communities. Removal is very costly and takes multiple years of different treatments like herbicide, mowing, and flooding. To ensure Phragmites australis does not return, native seeds will need to be sown. This experiment is to determine the best seed composition and sowing density. In the USU greenhouse, I will sow four different native seed mixes: 100% desirable perennial natives, 75% perennial natives and 25% fast growing natives, 50% perennial natives and 50% …


The Application Of Metacommunity Theory To The Management Of Riverine Ecosystems, Christopher J. Patrick, Kurt E. Anderson, Brown L. Brown, Et Al Jan 2021

The Application Of Metacommunity Theory To The Management Of Riverine Ecosystems, Christopher J. Patrick, Kurt E. Anderson, Brown L. Brown, Et Al

VIMS Articles

River managers strive to use the best available science to sustain biodi versity and ecosystem function. T o achieve this goal requires consideration of processes at different scales. Metacommunity theory describes how multiple species from differ- ent communities potentially interact with local-scale environmental drivers to influ- ence population dynamics and community structure. However, this body of knowledge has only rarely been used to inform management practices for river ecosystems. In this article, we present a conceptual model outlining how the metacommunity processes of local niche sorting and dispersal can influence the outcomes of management interventions and provide a series of …
