Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan
Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan
All Theses
Hurricanes have long been powerful and recurring disturbances in many coastal forest ecosystems. Intense hurricanes often produce a large amount of dead fuels within their affected forests, but how post-hurricane fuel complex changes with time, due to decomposition and management such as salvage, and the fire behavior affected by the changed fuel load remains largely unknown. To better understand the fuel and regeneration dynamics, field measurement and modeling were conducted within undamaged stands and hurricane damaged stands, including salvaged and unsalvaged stands in southern pine forests impacted by hurricane Hugo (1989), Opal (1995), Katrina (2005), and Ike (2008). We found …
Ecosystem Responses To Fuel Reduction Treatments In Stands Killed By Southern Pine Beetle, Aaron Stottlemyer
Ecosystem Responses To Fuel Reduction Treatments In Stands Killed By Southern Pine Beetle, Aaron Stottlemyer
All Dissertations
Heavy fuel loads were created by multiple southern pine beetle (Dendroctonus frontalis Ehrh.) outbreaks throughout the southern Piedmont between 1999 and 2002. Prescribed burning and mechanical mastication are proposed to reduce fuel loading in beetle-killed pine (Pinus L. spp.) stands in the upper South Carolina Piedmont, but their ecological impacts are unknown. Prescribed burning reduced fuelbed continuity by consuming litter (Oi) and fine (1- and 10-hr timelag size classes) woody fuels immediately after the treatment. Duff (Oe + Oa) layer thickness also decreased and mineral soil was exposed in some areas. Mastication resulted in a thick, continuous layer of shredded …

The physiognomy of Caribbean dry forest is shorter, denser and contains a greater proportion of multi-stemmed trees than other neotropical dry forests. Our previous research, conducted after Hurricane Georges in 1998, has shown that dry forest trees sprout near the base following hurricane disturbance, even if the trees have not incurred structural damage. However, for these hurricane-induced sprouts to contribute to the physiognomy of the forest, they must grow and survive. We followed sprout dynamics and stem mortality on 1,407 stems from 1998, after Hurricane Georges, until 2005. The number of surviving sprouts and the proportion of sprouting stems decreased …

Over 345,000 ha of forested swamps occur throughout the Mississippi River Deltaic Plain. Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available
science, suggestions for policy change, and a multidisciplinary (multi-responsibility) approach were needed to address these issues [in the context of private land]. In response, the Louisiana Governor's office formed a Coastal Wetland Forest Conservation and Use Science Working Group (SWG) and an associated …

Regeneration of baldcypress (Taxodium distichum (L.) Rich.) and water tupelo (Nyssa aquatica L.) in swamps of the deltaic plain of the Mississippi River are of major importance for ecosystem sustainability and forest management in the context of regional hydrological changes. Water tupelo often forms prolific sprouts from cut stumps, and baldcypress is one of few conifers to produce stump sprouts capable of becoming full-grown trees. Previous studies have addressed early survival of baldcypress stump sprouts, but have not addressed the likelihood of sprouts becoming an important component of mature stands. We surveyed stands in southeastern Louisiana that were partially logged …
