Modern Applied Statistics With S

The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 ± 0.4 petagrams of carbon per year (Pg C year–1) globally for 1990 to 2007. We also estimate a source of 1.3 ± 0.7 Pg C year–1 from tropical land-use change, consisting of a gross tropical deforestation emission of 2.9 ± 0.5 Pg C year–1 partially compensated by a carbon sink in tropical forest regrowth of 1.6 ± 0.5 Pg C year–1. Together, the fluxes comprise a net global forest sink of 1.1 ± 0.8 Pg C year–1, with tropical estimates having the largest uncertainties. Our total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks.

In fire-prone areas of the western United States, mechanical thinning is often seen as a way to achieve two outcomes: Wildfire mitigation and restoration of historical forest structure. In this study, a spatial modeling approach is used to (1) find which forests are likely to be thinned under different criteria; (2) for these forests, evaluate whether wildfire mitigation and restoration of historical forest structure are potentially needed; and (3) determine whether these results change under alternative assumptions related to weather and fire history. Effectively, the spatial models in this study allow us to “test” thinning criteria to see if they lead to the selection of land where the stated management goals are needed in the study area of the montane zone of Boulder County, Colo. The spatial modeling results indicate that common management practices—such as thinning dense stands on Forest Service land near communities—may be inappropriate if the desired outcome is both wildfire mitigation and restorat...

Spatial Model of Forest Management Strategies and Outcomes in the Wildland–Urban Interface

This paper reports the use of thin sections to improve precision and accuracy when ageing seedlings of Nothofagus pumilio. We compare 2 methods for determining the number of rings on 85 basal disks from seedlings: (1) ring counts of wood disks viewed with reflected light and (2) ring counts of thin sections viewed with transmitted light. Samples included 14 to 53 rings. Comparison of ring counts from the 2 methods revealed discrepancies of 1 to 12 y for 85% of the seedlings. Two sources of error were identified. In 70 of 85 samples, up to 12 incomplete rings explained differences between ring counts of 2 radii on the same wood disk. Secondly, the small radii, large number of rings, and diffuse porous nature of the wood resulted in frequent errors when visually detecting rings on wood disks. One to 3 false rings were detected in 15 seedlings. Narrow and suppressed rings in 57 samples resulted in under-estimates of 1 to 12 y for ring counts on wood disks relative to thin sections. High variation in...
