Coastal Plain Forest Plant Community Response To Hurricane Fire Interactions

This book provides a unique exploration of the inter-relationships between the science of plant environmental responses and the understanding and management of forest fires. It bridges the gap between plant ecologists, interested in the functional and evolutionary consequences of fire in ecosystems, with foresters and fire managers, interested in effectively reducing fire hazard and damage. This innovation in this study lies in its focus on the physiological responses of plants that are of relevance for predicting forest fire risk, behaviour and management. It covers the evolutionary trade-offs in the resistance of plants to fire and drought, and its implications for predicting fuel moisture and fire risk; the importance of floristics and plant traits, in interaction with landform and atmospheric conditions, to successfully predict fire behaviour, and provides recommendations for pre- and post- fire management, in relation with the functional composition of the community. The book will be particularly focused on examples from Mediterranean environments, but the underlying principles will be of broader utility.

A biodiversity hotspot, Florida is home to many ecosystems and species that evolved in the presence of frequent fire. In this book, Reed Noss discusses the essential role of fire in generating biodiversity and offers best practices for using fire to keep the region's ecosystems healthy and resilient. Reviewing several lines of evidence, Noss shows that fire has been important to the southeastern Coastal Plain for tens of millions of years. He explains how the region's natural fire regimes are connected to its climate, high rate of lightning strikes, physical chemistry, and vegetation. But urbanization and active fire suppression have reduced the frequency and extent of fires. Noss suggests the practice of controlled burning can and should be improved to protect fire-dependent species and natural communities from decline and extinction. Noss argues that fire managers should attempt to simulate natural fire regimes when conducting controlled burns. Based on what the species of the Southeast likely experienced during their evolutionary histories, he makes recommendations about pyrodiversity, how often and in what seasons to burn, the optimal heterogeneity of burns, mechanical treatments such as cutting and roller-chopping, and the proper use of fuel breaks. In doing so, Noss is the first to apply the new discipline of evolutionary fire ecology to a specific region. This book is a fascinating history of fire ecology in Florida, an enlightening look at why fire matters to the region, and a necessary resource for conservationists and fire managers in the state and elsewhere.

ABSTRACT: Although prescribed burning is an important management tool for ecosystem restoration in Cedar Key Scrub State Reserve, this is the first study that analyzes the effect of prescribed burning on plants and small mammals. In addition, this is the first research carried out on plant community response to prescribed fire in coastal scrub on the west side of Florida, and the 12th study about the effects of prescribed burning on small mammals in Florida. The main objectives were to determine: (a) if there were structural and compositional changes in the plant community after prescribed burning, (b) if small mammals used wetlands as temporal refugia after prescribed fire; and (c) if prescribed burning had a negative effect on the survival of the small mammal species.

Prescribed fire is a common land management tool in the southeastern United States. Historical fires occurred primarily in the growing season, but modern day prescribed fire is commonly restricted to the dormant season. Plant community responses to various fire regimes are relatively unknown, and managers require information on how fire regimes impact plant communities. To address these limitations, I studied the impacts of March and June fire on plant communities. Results indicated various woody midstory species respond differently to fire season and community response is driven by species composition. In another study, I examined impacts of February, May-June, and September-October backing and heading fires on midstory and understory vegetation. Results indicated May-June fires maximized midstory mortality and growing-season fires maximized herbaceous understory coverage while dormant-season fire promoted resprouting woody species. Managers can use this information to tailor fire prescriptions to specific properties to better meet management objectives.
