What influences planted tree seedling survival in burned Colorado montane forests?
Across the western United States, large, severe wildfires in montane forests are creating treeless patches that can fail to reforest naturally due to a lack of seed sources and a warming climate. Nursery-grown tree seedlings are commonly planted by land managers into these areas to promote forest recovery and resilience, but uncertainty exists about what influences their survival across the landscape. We obtained survival monitoring data that had been collected one growing season after planting for 5656 tree seedlings, which were distributed across nine montane wildfires and four National Forests in Colorado, USA. We used these data to examine how seedling survival varied across a range of factors, including long-term average climatic conditions, post-planting weather conditions, and locations and species of seed lot collection. We found that survival after one growing season averaged 80 % across all plots but ranged from 0 % to 100 %. Survival was greater at cooler, wetter sites and at sites planted in warmer, wetter years. Survival was also greater for ponderosa pine than for Douglas-fir, and when the locally collected seed lot used to produce the seedlings came from a site that was lower in elevation than the planting site. Our results suggest that the location and timing of tree planting, and the plant materials used, play critical roles in planting success in Colorado montane wildfires, and should help land managers optimize post-fire planted seedling survival under both current and future climatic conditions.
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.
