Title Toward a Social-Ecological Theory of Forest Macrosystems for Improved Ecosystem Management Type Journal Article
Year 2018 Publication Forests Abbreviated Journal Forests
Volume 9 Issue 4 Pages 200
Keywords macrosystem; macroscale; forest; management; ecosystem function; ecosystem service; cross-scale; trade-off; governance; social-ecological system
Abstract The implications of cumulative land-use decisions and shifting climate on forests, require us to integrate our understanding of ecosystems, markets, policy, and resource management into a social-ecological system. Humans play a central role in macrosystem dynamics, which complicates ecological theories that do not explicitly include human interactions. These dynamics also impact ecological services and related markets, which challenges economic theory. Here, we use two forest macroscale management initiatives to develop a theoretical understanding of how management interacts with ecological functions and services at these scales and how the multiple large-scale management goals work either in consort or conflict with other forest functions and services. We suggest that calling upon theories developed for organismal ecology, ecosystem ecology, and ecological economics adds to our understanding of social-ecological macrosystems. To initiate progress, we propose future research questions to add rigor to macrosystem-scale studies: (1) What are the ecosystem functions that operate at macroscales, their necessary structural components, and how do we observe them? (2) How do systems at one scale respond if altered at another scale? (3) How do we both effectively measure these components and interactions, and communicate that information in a meaningful manner for policy and management across different scales?

Title Response to Temperature and Virulence Assessment of Fusarium circinatum Isolates in the Context of Climate Change Type Journal Article
Year 2019 Publication Forests Abbreviated Journal Forests
Volume 10 Issue 1 Pages
Keywords pitch canker; loblolly pine; slash pine; pathogenicity; temperature response; screening tests; climate change
Abstract With future global temperatures predicted to increase, the relationship between a host, pathogen, and environment, becomes less predictable and epidemics may pose a greater risk to forests worldwide. Resistance breeding is an important disease management tool, but because tree species require long breeding times, it is necessary to develop techniques for testing current pathogen isolates against their hosts. Pitch canker disease of pines, caused by the pathogen Fusarium circinatum, is no exception and represents a threat to pine forests and commercial plantations worldwide, as it thrives at warm temperatures and high humidity. We tested growth of 15 F. circinatum isolates in culture at three temperatures: 25, 27, and 31 degrees C. We also evaluated the sporulation and pathogenicity of eight of the isolates on two susceptible Pinus elliotti (slash pine) open-pollinated families and one tolerant open-pollinated Pinus taeda (loblolly pine) family. Our results showed significant differences among isolates in the temperature and pathogenicity tests. All isolates showed a significant decrease in growth at 31 degrees C, although some showed similar growth at 25 and 27 degrees C. Several of the new isolates tested were more pathogenic than the isolates that the USDA Forest Service Resistance Screening Center (RSC) had been using. The new isolates have now been incorporated into their operational screening program.

Title Impacts of Climate Change and Bioenergy Markets on the Profitability of Slash Pine Pulpwood Production in the Southeastern United States Type Journal Article
Year 2018 Publication Forests Abbreviated Journal Forests
Volume 9 Issue 10 Pages 656
Keywords slash pine; bioenergy; climate change; land expectation value; harvest age; Southeastern US
Abstract In this study, we assessed the impacts of climate change on the production of pulpwood and biomass for bioenergy, and the profitability of slash pine stands in the Southeastern United States. We employed the 3-PG (Physiological Processes Predicting Growth) model to determine the effects of future climates on forest growth and integrated it with a stand-level economic model to determine their impacts on optimal forest management. We found that the average production of pulpwood increased for all sites by 7.5 m3 ha−1 for all climatic scenarios and productivity conditions. In the case of forest biomass for bioenergy, the average increase was less than 1 Mg ha−1. Considering a payment for forest biomass for bioenergy of $4.2 per green Mg−1, the land expectation values (LEVs), on average, increased by $242.1 ha−1 under extreme climatic conditions and high productivity conditions. However, the increase in LEVs due to payments for biomass for bioenergy was small, accounting for $23 ha−1. We also found that the combined effect of increased site productivity and climate change reduced the optimal harvest age of slash pine. Our results confirm that emerging bioenergy markets coupled with changing climatic conditions can increase the economic returns for landowners. View Full-Text
