Disturbance history has limited influence on subalpine fir decline
In conifer forests of western North America, disturbances including wildfire and outbreaks of multiple species of native bark beetles periodically cause widespread tree mortality, the legacies of which can last decades. Past disturbances can influence the occurrence or severity of future disturbances, causing long-term changes in forest trajectories. Despite their importance, the causes and consequences of interactions among disturbances, especially bark beetle interactions, are poorly understood. In a multi-scale study including both field and geospatial data, we explored how legacies of different disturbances affected future occurrence and severity of subalpine fir (Abies lasiocarpa) decline (SFD) from recent (1999–2019) outbreaks of the western balsam bark beetle (Dryocoetes confusus) and associated fungal pathogens. We collected field data on stand structure and SFD at 27 sites in the White River National Forest, CO, USA, which experienced stand-replacing fires ca. 1879 and a severe spruce beetle (SB) outbreak in the 1940s, leaving a mosaic of different disturbance histories which might affect recent SFD. At the landscape scale, occurrence of SFD was most common in younger forests that had experienced stand-replacing fires ca. 1879. In forests with occurrence of SFD, stand-scale severity of SFD did not vary with disturbance history or stand structure, but was influenced by topography. For an individual tree, we found that susceptibility to SFD was most strongly associated with tree size and proximity to other SFD-affected trees, though presence of 1940s SB had a small, negative effect. Though our findings broadly support previous research on SFD dynamics, weak connections between disturbance history and SFD underscore the variability in forest recovery after disturbance, highlighting the need for future research.
期刊介绍:
Forest Ecology and Management publishes scientific articles linking forest ecology with forest management, focusing on the application of biological, ecological and social knowledge to the management and conservation of plantations and natural forests. The scope of the journal includes all forest ecosystems of the world.
A peer-review process ensures the quality and international interest of the manuscripts accepted for publication. The journal encourages communication between scientists in disparate fields who share a common interest in ecology and forest management, bridging the gap between research workers and forest managers.
We encourage submission of papers that will have the strongest interest and value to the Journal''s international readership. Some key features of papers with strong interest include:
1. Clear connections between the ecology and management of forests;
2. Novel ideas or approaches to important challenges in forest ecology and management;
3. Studies that address a population of interest beyond the scale of single research sites, Three key points in the design of forest experiments, Forest Ecology and Management 255 (2008) 2022-2023);
4. Review Articles on timely, important topics. Authors are welcome to contact one of the editors to discuss the suitability of a potential review manuscript.
The Journal encourages proposals for special issues examining important areas of forest ecology and management. Potential guest editors should contact any of the Editors to begin discussions about topics, potential papers, and other details.
