Enormous wildfires spark scramble to improve fire models

  
Nature, Vol. 561, No. 7721. (31 August 2018), pp. 16-17, https://doi.org/10.1038/d41586-018-06090-0

Abstract

Blazes in North America are becoming larger and more powerful. [Excerpt] [...] “Something is definitely different, and it raises questions about how much we really know,” says Max Moritz, a fire scientist at the University of California, Santa Barbara. [...] Researchers have been at a loss to explain a flurry of unusual fire behaviour in California in recent years: wildfires that burn hot throughout the night instead of settling down, as many used to; blazes that race down hillsides faster than before; ...

 

Human-Related Ignitions Increase the Number of Large Wildfires across U.S. Ecoregions

  
Fire, Vol. 1, No. 1. (27 January 2018), 4, https://doi.org/10.3390/fire1010004

Abstract

Large fires account for the majority of burned area and are an important focus of fire management. However, ‘large’ is typically defined by a fire size threshold, minimizing the importance of proportionally large fires in less fire-prone ecoregions. Here, we defined ‘large fires’ as the largest 10% of wildfires by ecoregion (n = 175,222 wildfires from 1992 to 2015) across the United States (U.S.). Across ecoregions, we compared fire size, seasonality, and environmental conditions (e.g., wind speed, fuel moisture, biomass, vegetation ...

 

Land use strategies to mitigate climate change in carbon dense temperate forests

  
Proceedings of the National Academy of Sciences, Vol. 115, No. 14. (03 April 2018), pp. 3663-3668, https://doi.org/10.1073/pnas.1720064115

Abstract

[Significance] Regional quantification of feasibility and effectiveness of forest strategies to mitigate climate change should integrate observations and mechanistic ecosystem process models with future climate, CO2, disturbances from fire, and management. Here, we demonstrate this approach in a high biomass region, and found that reforestation, afforestation, lengthened harvest cycles on private lands, and restricting harvest on public lands increased net ecosystem carbon balance by 56% by 2100, with the latter two actions contributing the most. Forest sector emissions tracked with our life ...

 

Adapt to more wildfire in western North American forests as climate changes

  
Proceedings of the National Academy of Sciences, Vol. 114, No. 18. (02 May 2017), pp. 4582-4590, https://doi.org/10.1073/pnas.1617464114

Abstract

Wildfires across western North America have increased in number and size over the past three decades, and this trend will continue in response to further warming. As a consequence, the wildland–urban interface is projected to experience substantially higher risk of climate-driven fires in the coming decades. Although many plants, animals, and ecosystem services benefit from fire, it is unknown how ecosystems will respond to increased burning and warming. Policy and management have focused primarily on specified resilience approaches aimed at resistance ...

 

The interaction of fire, fuels, and climate across Rocky Mountain forests

  
BioScience, Vol. 54, No. 7. (2004), pp. 661-676, https://doi.org/10.1641/0006-3568(2004)054[0661:tioffa]2.0.co;2

Abstract

Understanding the relative influence of fuels and climate on wildfires across the Rocky Mountains is necessary to predict how fires may respond to a changing climate and to define effective fuel management approaches to controlling wildfire in this increasingly populated region. The idea that decades of fire suppression have promoted unnatural fuel accumulation and subsequent unprecedentedly large, severe wildfires across western forests has been developed primarily from studies of dry ponderosa pine forests. However, this model is being applied uncritically across ...

 

Anthropogenic forcings and associated changes in fire risk in Western North America and Australia during 2015-2016

  
Bulletin of the American Meteorological Society In Explaining Extreme Events of 2016 from a Climate Perspective, Vol. 99, No. 1. (January 2018), pp. S60-S64, https://doi.org/10.1175/BAMS-D-17-0096.1

Abstract

Extreme vapor pressure deficits (VPD) have been associated with enhanced wildfire risk. Using one model, we found for 2015/16 that human influences quintupled the risk of extreme VPD for western North America and increased the risk for extratropical Australia. [Excerpt: Introduction] In 2016, about 3.6 million hectares of land burned in the United States and Canada (NIFC 2017; NFD 2017). In Canada, a wildfire southwest of Fort McMurray, Alberta, caused the largest wildfire evacuation in Alberta’s history and destroyed 2400 homes ...

 

Impact of food and predation on the snowshoe hare cycle

  
Science, Vol. 269, No. 5227. (25 August 1995), pp. 1112-1115, https://doi.org/10.1126/science.269.5227.1112

Abstract

Snowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8 years in the Yukon. Two blocks of forest were fertilized to test for nutrient effects. Predator exclosure doubled and food addition tripled hare density during the cyclic peak and decline. Predator exclosure combined with food addition increased density 11-fold. Added nutrients increased plant growth but not hare density. Food and ...

 

Influence of tree species on continental differences in boreal fires and climate feedbacks

  
Nature Geoscience, Vol. 8, No. 3. (2 February 2015), pp. 228-234, https://doi.org/10.1038/ngeo2352

Abstract

Wildfires are common in boreal forests around the globe and strongly influence ecosystem processes. However, North American forests support more high-intensity crown fires than Eurasia, where lower-intensity surface fires are common. These two types of fire can result in different net effects on climate as a consequence of their contrasting impacts on terrestrial albedo and carbon stocks. Here we use remote-sensing imagery, climate reanalysis data and forest inventories to evaluate differences in boreal fire dynamics between North America and Eurasia and ...

 

Future wildfire in circumboreal forests in relation to global warming

  
Journal of Vegetation Science, Vol. 9, No. 4. (August 1998), pp. 469-476, https://doi.org/10.2307/3237261

Abstract

Despite increasing temperatures since the end of the Little Ice Age (ca. 1850), wildfire frequency has decreased as shown in many field studies from North America and Europe. We believe that global warming since 1850 may have triggered decreases in fire frequency in some regions and future warming may even lead to further decreases in fire frequency. Simulations of present and future fire regimes, using daily outputs from the General Circulation Model (GCM), were in good agreement with recent trends observed ...

Model projections of an imminent transition to a more arid climate in Southwestern North America

  
Science, Vol. 316, No. 5828. (2007), pp. 1181-1184, https://doi.org/10.1126/science.1139601

Abstract

How anthropogenic climate change will affect hydroclimate in the arid regions of southwestern North America has implications for the allocation of water resources and the course of regional development. Here we show that there is a broad consensus among climate models that this region will dry in the 21st century and that the transition to a more arid climate should already be under way. If these models are correct, the levels of aridity of the recent multiyear drought or the Dust ...

 

The unusual nature of recent snowpack declines in the North American cordillera

  
Science, Vol. 333, No. 6040. (2011), pp. 332-335, https://doi.org/10.1126/science.1201570

Abstract

In western North America, snowpack has declined in recent decades, and further losses are projected through the 21st century. Here, we evaluate the uniqueness of recent declines using snowpack reconstructions from 66 tree-ring chronologies in key runoff-generating areas of the Colorado, Columbia, and Missouri River drainages. Over the past millennium, late 20th century snowpack reductions are almost unprecedented in magnitude across the northern Rocky Mountains and in their north-south synchrony across the cordillera. Both the snowpack declines and their synchrony result ...

 

Nature vs. nurture: managing relationships between forests, agroforestry and wild biodiversity

  
Agroforestry Systems, Vol. 61-62, No. 1-3. (2004), pp. 155-165, https://doi.org/10.1023/b%3aagfo.0000028996.92553.ea

Abstract

Many agroforestry systems are found in places that otherwise would be appropriate for natural forests, and often have replaced them. Humans have had a profound influence on forests virtually everywhere they both are found. Thus ‘natural’ defined as ‘without human influence’ is a hypothetical construct, though one that has assumed mythological value among many conservationists. Biodiversity is a forest value that does not carry a market price. It is the foundation, however, upon which productive systems depend. The relationship between agroforestry ...

No-analog climates and shifting realized niches during the late quaternary: implications for 21st-century predictions by species distribution models

  
Global Change Biology, Vol. 18, No. 5. (1 May 2012), pp. 1698-1713, https://doi.org/10.1111/j.1365-2486.2011.02635.x

Abstract

Empirically derived species distributions models (SDMs) are increasingly relied upon to forecast species vulnerabilities to future climate change. However, many of the assumptions of SDMs may be violated when they are used to project species distributions across significant climate change events. In particular, SDM's in theory assume stable fundamental niches, but in practice, they assume stable realized niches. The assumption of a fixed realized niche relative to climate variables remains unlikely for various reasons, particularly if novel future climates open up ...

Cross-scale Drivers of Natural Disturbances Prone to Anthropogenic Amplification: The Dynamics of Bark Beetle Eruptions

  
BioScience, Vol. 58, No. 6. (01 June 2008), pp. 501-517, https://doi.org/10.1641/b580607

Abstract

Biome-scale disturbances by eruptive herbivores provide valuable insights into species interactions, ecosystem function, and impacts of global change. We present a conceptual framework using one system as a model, emphasizing interactions across levels of biological hierarchy and spatiotemporal scales. Bark beetles are major natural disturbance agents in western North American forests. However, recent bark beetle population eruptions have exceeded the frequencies, impacts, and ranges documented during the previous 125 years. Extensive host abundance and susceptibility, concentrated beetle density, favorable weather, optimal ...

 

Biology and Control of Bacterial Leaf Blight of Cornus mas

  
HortScience, Vol. 41, No. 3. (2006), pp. 721-724

Abstract

Cornelian cherry (Cornus mas L.) has been free of disease and pest problems until recently when a bacterial leaf blight caused by Pseudomonas syringae was reported. Since its first observation in middle Tennessee in 1999, the disease has become endemic in the nursery where it was first discovered. The objective of this study was to assess the disease, evaluate factors that favor disease development, and develop disease management strategies. Cool temperatures of 20 to 24 °C (day) and 10 to 15 ...

Selection of willows for floral and stem quality and continuous sequence in temperate North America

  
HortTechnology, Vol. 14, No. 3. (2004), pp. 415-419

Abstract

The study addresses the problem of diversification and quality of willow (Salix) cut stems. Very few ornamental willow species are currently in production for the cut-stem trade in temperate North America, and they have a relatively short annual harvest period. This study selected 20 taxa of willow with the potential for cut-stem industry based on observations of more than 150 taxa in central Ohio for 4 years. Growth and ornamental qualities of branches and inflorescences of those species, hybrids, or cultivars ...

 

Response of Native and Exotic Maple Seedling Banks to Removal of the Exotic, Invasive Norway Maple (Acer platanoides)

  
Journal of the Torrey Botanical Society, Vol. 128, No. 2. (2001), pp. 141-149

Abstract

Acer platanoides is an exotic, invasive tree in eastern deciduous forests of North America where past research shows it to thrive in the forest interior and to suppress understory diversity. To test the efficacy of restoration strategies and to probe dynamics of this tree's seedling bank, trees and seedlings of Acer platanoides were removed in 1997 from a mixed maple forest carpeted by an even mix of exotic Acer platanoides and native Acer saccharum seedlings. The treatments were removal of trees ...

In Invasive species fact sheet (2011)

Abstract

The Pennsylvania flora includes 3,091 species of vascular plants. Sixty-nine percent of these are plant species that evolved in eastern North America along with other indigenous plants and animals. The remaining thirty-one percent consist of plants that evolved elsewhere and have been brought to Pennsylvania through the actions of humans. Plant introductions have been both deliberate and accidental. Many cultivated plants were brought by the earliest European settlers. Most of our agricultural crops and ornamental garden plants originated in other parts of ...

Don't blame the beetles

  
Science, Vol. 346, No. 6206. (10 October 2014), pp. 154-156, https://doi.org/10.1126/science.346.6206.154

Abstract

Tiny insects called bark beetles have devastated forests in western North America over the past decade. Life has drained from millions of hectares of forest so quickly that it seemed as if they had been abruptly unplugged, like a Christmas tree before bedtime. And many people have feared the infestation's fallout, worrying that the dry, beetle-killed trees would give birth to huge, damaging wildfires. Those concerns seemed to come true as spectacular blazes, such as the 2012 High Park Fire near ...

 

Phenology is a major determinant of tree species range

  
Ecology Letters, Vol. 4, No. 5. (14 August 2001), pp. 500-510, https://doi.org/10.1046/j.1461-0248.2001.00261.x

Abstract

Global warming is expected to have a major impact on plant distributions, an issue of key importance in biological conservation. However, very few models are able to predict species distribution accurately, although we know species respond individually to climate change. Here we show, using a process-based model (PHENOFIT), that tree species distributions can be predicted precisely if the biological processes of survival and reproductive success only are incorporated as a function of phenology. These predictions showed great predictive power when tested ...
