Post Wildfire Vegetation Response To The Wildland-Urban Interface: A Case Study Of The Station Fire, Angelo C. De Guzman, Raju Bista, Parveen K. Chhetri

CSU Journal of Sustainability and Climate Change

In the past, wildfires served as a method for mother nature to promote biodiversity and to help maintain a functioning ecosystem. However, climate change alters the fire regime, significantly impacting vegetation recovery. Human disturbances and increased land use and land cover heighten vegetation disruption and abundance after a fire. Wildland-urban interface (WUI) – the region where the vegetation intermingles with the roads, houses, and human-made structures – threatens vegetation and the human population. Overall vegetation recovery after the Station Fire of 2009 spread through the San Gabriel Mountains, Los Angeles County was observed using Digital Elevation Model (DEM), Normalized Difference …

Draft State Legislation: Agricultural Energy Net Metering & Power Purchasing, Samuel C. Kessler, Austin Gabhart May 2022

Draft State Legislation: Agricultural Energy Net Metering & Power Purchasing, Samuel C. Kessler, Austin Gabhart

Commonwealth Policy Papers

This draft legislation was first authored by Commonwealth Policy Coalition Associates Samuel Kessler and Austin Gabhart in 2018, and is now published in 2022 to provide a method of creating improved Agricultural Net Metering and Power Purchase Agreements for agriculture-based energy developments. Shortly after this time, the Commonwealth of Virginia passed similar legislation directly dealing with renewable Net Metering and eventually Power Purchase Agreements in an agricultural context. Those especially in states which do not have Renewable Energy Portfolios which may or may not entail concerns with those portfolios and stakeholders in the nonrenewable industry are urged to consider implementation …

Leap: Land Endowment Action Plan For Sustainable Colby, Victoria Palffy Aug 2014

Leap: Land Endowment Action Plan For Sustainable Colby, Victoria Palffy

Journal of Environmental and Resource Economics at Colby

This paper proposes that Colby College purchase land endowments to fuel its recently constructed campus biomass plant. Rather than contract with a third party, the college should invest in 30,000 acres2 and sustainably harvest its own renewable fuel. Beyond this, LEAP, the land endowment action plan, presents an opportunity to improve forest health, conserve valuable ecosystems, implement major additions to the curriculum, gain fuel independence, and create a constant annual revenue stream. With a 40-year payback period, the long-term investment brings profits of over $260 million in its 100-year outlook.

Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best Jan 2006

Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best

Journal of the Iowa Academy of Science: JIAS

As Conservation Reserve Program (CRP) contracts expire, many fields may be returned to agricultural production. Growing switchgrass (Panicum virgatum) as a biomass fuel is an alternative to returning fields to rowcrops. CRP fields provide winter cover for birds, but the harvest of biomass would remove most of the cover and affect bird use of the fields. We estimated winter bird abundances in nonharvested, total-harvested, and partially (strip) harvested switchgrass fields in southern Iowa. Song sparrows (Melospiza melodia) were observed only in strip-harvested fields and ring-necked pheasants (Phasianus colchicus) were observed only in nonharvested fields and uncut areas of strip-harvested fields. …

Biomass Yield Stability In Alfalfa, Joseph G. Robins, Heathcliffe Riday, Sara J. Helland, E. Charles Brummer Jan 2004

Biomass Yield Stability In Alfalfa, Joseph G. Robins, Heathcliffe Riday, Sara J. Helland, E. Charles Brummer

Journal of the Iowa Academy of Science: JIAS

In addition to biomass production, alfalfa (Medicago sativa) cultivars also need to express yield stability across diverse environments. The objective of this experiment was to analyze the nature of biomass yield stability in ten commercial alfalfa cultivars by evaluating performance of individual genotypes. Biomass yield was measured in each of five environments across two years, and the yield stability computed for the overall cultivar mean performance and the mean performance of each of the genotypes comprising the cultivars using the genotype x environment variance statistic of Shukla and the superiority statistic of Lin and Binns'. The GxE variance of the …

Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold Jan 2002

Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Switchgrass (Panicum virgatum L.) is a native perennial prairie grass that is now cultivated as a forage crop and a biomass crop for renewable energy. Biomass yields of switchgrass in southern Iowa have recently dropped significantly in some fields and the reduction has been attributed to disease. A disease survey was conducted in 1999 to assess the prevalence of major diseases in Chariton Valley switchgrass production. There were disease symptoms present on switchgrass plants in each field and thirteen fungal species were identified from leaf, stem, and root samples. Two pathogenic fungi, Tilletia maclaganii and Colletotrichum graminicola, were present in …
