Monitoring Northeastern United States Forest Condition Using Landsat Data
The broad overviews obtained with Landsat data can provide information concerning the location, types, and magnitudes of forest changes not easily obtainable by other means. One of the main goals of the current study is to provide spatial information regarding the more subtle forms of forest change rather than those primarily related to land cover conversion. A forest-dominated area in northern...
متن کاملBenchmarking and Calibration of Forest Vegetation Simulator Individual Tree Attribute Predictions Across the Northeastern United States
period (5 years) after updating the individual tree-mortality submodel in FVS’s Southern variant (Radtke et al. 2012). On the other hand, Rijal et al. (2012a, 2012b) recently found refitting FVS-NE tree height and crown ratio equations to be ineffective for improving predictions when compared to utilizing a different equation form for several species in Maine. This suggests that effectiveness o...
متن کاملThe Effects of Silvicultural Treatment on Sirex noctilio Attacks and Tree Health in Northeastern United States
The invasive woodwasp Sirex noctilio (Hymenoptera: Siricidae) is established in east-central North America. A replicated case study testing the effectiveness of silvicultural treatments for reducing the number of S. noctilio attacked trees in a stand was conducted in New York, USA. Silvicultural treatments reduced S. noctilio attacked trees by approximately 75% over the course of the study. The...
متن کاملCorrection: Statistically-Estimated Tree Composition for the Northeastern United States at Euro-American Settlement
We present a gridded 8 km-resolution data product of the estimated composition of tree taxa at the time of Euro-American settlement of the northeastern United States and the statistical methodology used to produce the product from trees recorded by land surveyors. Composition is defined as the proportion of stems larger than approximately 20 cm diameter at breast height for 22 tree taxa, genera...
متن کاملReconstructing tritium exposure using tree rings at Lawrence Berkeley National Laboratory, California.
Annual tritium exposures were reconstructed using tree cores from Pinus jeffreyi and Eucalyptus globulus near a tritiated water vapor release stack. Both tritium (3H) and carbon-14 (14C) from the wood were measured from milligram samples using accelerator mass spectrometry. Because the annual nature of the eucalyptus tree rings was in doubt, 14C measurements provided growth rates used to estima...
