Spatially Heterogeneous Estimates of Fire Frequency in Ponderosa Pine Forests of Washington, USA

James T. Kernan, Amy E. Hessl
2010 Fire Ecology  
We used a dataset of fire-scarred trees collected from four sites in eastern Washington, USA, ponderosa pine (Pinus ponderosa C. Lawson) forests.  ...  Such information can reveal ecological relationships between fire and the landscape, and provide managers with an improved spatial perspective on fire frequency that can inform risk evaluations, fuels  ...  ACKNOWLEDGEMENTS This research was funded in part by a Geography and Regional Science, National Science Foundation Doctoral Dissertation Improvement Grant #NSF DDRI BCS 0508984.  ...

A review of Canadian remote sensing applications in hydrology, 1995-1999

Alain Pietroniro, Robert Leconte
2000 Hydrological Processes  
Canadian hydrologist and glaciologists have historically viewed remote sensing as an important tool in monitoring glacier fluctuations (Ostrem, 1975) with important implications for water management.  ...  This paper reviews recent (1995—99) remote sensing contributions in hydrology by Canadians, specifically focusing on the usefulness and applicability of current remote sensing technology for water management  ...

Tree spatial patterns in fire-frequent forests of western North America, including mechanisms of pattern formation and implications for designing fuel reduction and restoration treatments

Andrew J. Larson, Derek Churchill
2012 Forest Ecology and Management  
In this review we synthesize the available spatial reference information for fire-frequent pine and mixed-conifer forests in western North America; interpret this information in the context of restoration  ...  Based on these findings, we encourage managers to consciously adopt a view of forest structure that accommodates spatial heterogeneity within forest stands, and to use this conceptualization of forest  ...  We thank Helen Smith of the USFS Rocky Mountain Research Station Missoula Fire Sciences Lab for providing the data used in Figs. 7 and 8.  ...
