title: NOAA/WDS Paleoclimatology - Esper - Zermatt HCZ01 - LADE - ITRDB CHE602

description: Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives.  Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets.  Each data type is stored in a separate data file; the data type is coded into the file name.

title: NOAA/WDS Paleoclimatology - North fire data from Rust Ridge - IMPD USRST001

description: There have been few fire history studies of eastern Sierra Nevada forests in California, USA, where a steep elevation gradient, rain shadow conditions, and forest stand isolation may produce different fire regimes than those found on the range's western slope. We investigated historic fire regimes and potential climate influences on four forest types ranging in elevation from 1700 m to 3200 m on the Sierra Nevada's eastern slope and the White Mountains' western slope. Sample areas (approximately 15 ha to 45 ha) had mean site fire return intervals ranging from 4.8 yr to 16.9 yr across ten Jeffrey pine (Pinus jeffreyi Balf.) sites, and 13.4 yr to 45.7 yr across four high elevation lodgepole (P. contorta Douglas ex Louden), foxtail (P. balfouriana Balf.) and bristlecone (P. longaeva D.K. Bailey) pine sites. At most sites (13 of 14), >50 % of fire events occurred in late or dormant season wood. Twentieth century fire return intervals increased at some sites, while other sites continued to record frequent fire events into the 1950s. Years where two or more sites recorded fire events on two or more trees were correlated with drought conditions forecast by the Palmer Drought Severity Index (PDSI) in our sample locations at and north of Mammoth Lakes. The lower Sierra Nevada crest due west of these locations may connect weather patterns with western slope conditions more than at our southern eastside sample sites, which were not significantly correlated with PDSI. Our results suggest eastern Sierra Nevada Jeffrey pine forests have similar seasonality and fire return intervals as some western slope forests, but site fire history can be influenced by stand isolation, historical use, and local rain shadow conditions.

title: NOAA/WDS Paleoclimatology - Therrell et al. 2006 Central Mexico Maize Yield Reconstruction: 1474-2001

description: Maize was domesticated more than 6,000 years ago in central Mexico, and remains a vital staple food and cultural symbol in Mesoamerica. Maize yield in the central highlands is strongly dependant on adequate rainfall early in the growing season (April–June) because late maturation of the crop may result in damage from autumn frost. Climate-induced crop failures with profound socioeconomic impacts have punctuated Mexican history. However, reliable records of maize harvest have not been available until very recently, and historical records of crop yield and price are discontinuous and can be difficult to interpret. We have developed a continuous, exactly dated, tree-ring reconstruction of maize yield variability in central Mexico from 1474 to 2001 that provides new insight into the history of climate and food availability in the heartland of the Mesoamerican cultural province. The reconstruction indicates that seven of the most severe agricultural crises in Mexican history occurred during decadal-scale episodes of reconstructed maize shortfalls.
description: 205 radii from 85 trees and fallen logs from the relict stand of ancient Douglas-fir at Cuauhtemoc la Fragua, Puebla, were used to compile earlywood, latewood, and total ring width chronologies extending from 1474–2001. The latewood chronology has been used to develop a high quality reconstruction of annual maize yield for the late prehispanic, colonial, and modern eras in the heart of highland Mexico. For this study we use maize "yield" data from the three states of Puebla, Tlaxcala, and Veracruz compiled by the Secretaria de Agricultura, Ganaderia, Desarrollo Rural, Pesca y Alimentacion. The yield data represent statewide average production in tonnes (1000 kg) per ha. The average three-state yield over the 22-year period is 1.65 t/ha. The overall correlation (r) between the latewood (LW) chronology and the combined three state maize yield from 1980 to 2001 is 0.79. The regression equation Yt = 0.796 + 0.862Xt explains 60% of the maize yield variability (Yt is the estimated maize yield (tonnes per hectare) for year t, and Xt is the corresponding Cuauhtemoc LW value in year t. Following calibration and verification, the observed and reconstructed maize yield data were normalized and represent standardized anomalies from the calibration period mean (1.65 t/ha).

title: NOAA/WDS Paleoclimatology - North fire data from Last Chance Creek Riparian/upland - IMPD USLC_001

description: Fire is an important ecological process in many western U.S. coniferous forests, yet high fuel loads, rural home construction and other factors have encouraged the suppression of most wildfires. Using mechanical thinning and prescribed burning, land managers often try to reduce fuels in strategic areas with the highest fuel loads. Riparian forests, however, are often designated as areas where only limited management action can take place within a fixed-width zone. These highly productive forests have developed heavy fuel loads capable of supporting stand-replacing crown fires that can alter wildlife habitat and ecosystem function, and contribute to stream channel erosion. Objectives of this study were to determine whether adjacent coniferous riparian and upland forests burned historically with different frequencies and seasonalities, and whether these relationships varied by forest, site, and stream characteristics. We measured dendrochronological fire records in adjacent riparian and upland areas across a variety of forest, site and stream conditions at 36 sites in three sampling areas in the northern Sierra Nevada.  Riparian fire return intervals (FRI) ranged from 8.4 to 42.3 years under a liberal filter (mean 16.6), and 10.0 to 86.5 years under a conservative filter (mean 30.0). Upland FRI ranged from 6.1 to 58.0 years under a liberal filter (mean 16.9), and 10.0 to 56.3 years under a conservative filter (mean 27.8). Riparian and upland fire return intervals were significantly different in only one quarter of the sites we sampled. Riparian and upland areas did not burn with different seasonalities, and fire events occurred primarily during the late summer-early fall dormant season in both riparian and upland areas (88% and 79% of scars, respectively). FRI was shorter in forests with a higher proportion (>22.7-37.6%) of fire-tolerant pine(Pinus spp.), sites east of the Sierra crest, lower elevation sites (<1944 m), and riparian zones bordering narrower, more incised streams (width/depth ratio <6.2). Upland areas exhibited a greater degree of fire-climate synchrony than riparian areas. Our study suggests that Sierra Nevada coniferous riparian forests bordering many montane streams might be managed for fuel loads and fire return intervals similar to adjacent upland forests.
