“…Drought in the late 17th and early 18th centuries (1695-1707) has been reported in other paleoclimatic reconstructions from Chihuahua (Villanueva-Díaz et al, 2015) and Durango (Cerano-Paredes et al, 2012); moreover, PDSI spatial correlation analysis shows that the greatest intensity of this drought was concentrated in those states (Figure 7A). Drought affectation in the mid-18th century, with a duration of almost 20 years (1751-1768), extended over a large part of northern Mexico and southern United States (Figure 7B), corroborating that reported by Cook et al (2009) and Cerano-Paredes et al (2011a).…”

Introduction: Tree rings play a significant role for the reconstruction of climate variables on century scales. Objective: To reconstruct the variability of precipitation for the western part of the state of Chihuahua, based on tree rings of Pseudotsuga menziesii (Mirb.) Franco, Pinus arizonica Engelm.and Pinus strobiformis Engelm. Materials and methods: Samples were extracted with a Pressler drill, dated and growth indexes were generated based on dendrochronological techniques. A correlation analysis was run between regional chronology and observed precipitation data. A regression model was used to reconstruct precipitation. A spectral analysis determined the recurrence of droughts and the influence of El Niño Southern Oscillation (ENSO) on precipitation variability. Results and discussion: The relationship between the chronologies was statistically significant and a regional series of 359 years was developed. October-June precipitation had the highest impact on growth (r = 0.73, P < 0.01), so the variability of precipitation for that period was reconstructed for the last 359 years. Severe droughts were detected in the periods 1751-1768, 1807-1810 and 1945-1956 and a recurrence of droughts every 50 years was identified. The reconstructed precipitation variability is significantly modulated by ENSO at different time scales and frequencies. Conclusion: Paleoclimatic series help us to spread the knowledge of climate in specific geographic regions and to analyze the recurrence of extreme events (droughts).

“…Pseudotsuga menziesii was part of the forest at the LS site, where some trees have survived numerous low-intensity fires over 400 years (Cerano-Paredes et al 2012). This species is subject to special protection (SEMARNAT 2010) and could be in danger of disappearing in the Upper Nazas if stand-replacing fires occur.…”

Climatic influence on fire regime (1700 to 2008) in the Nazas watershed, Durango, Mexico

Background: Fire scars are the primary source of physical evidence used to date past fires around the world, and to estimate parameters of historical fire regimes and fire-climate relationships. Despite an increase in studies about historical fire regimes and the relationship between fire and climate, these studies are still limited for Mexican forests. Our goal was to characterize the historical fire regime in two sites with different elevations, to assess changes in fire frequency, and to determine the relationship between fire regimes and climate patterns in a conifer-dominated forest in the Upper Nazas watershed of the Sierra Madre Occidental, Mexico. We were able to cross-date 50 fire-scarred samples of Pinus arizonica Engelm., P. strobiformis Engelm., P. teocote Schlecht. & Cham., P. durangensis Martínez, and Pseudotsuga menziesii (Mirb.) Franco and identify a total of 596 fire scars. Results: Evidences are compelling evidences on forest fires occurred frequently in the study area, starting in the mid eighteenth century and through the mid twentieth century. The season of fire occurrence was determined for 560 (94%) fire scars. Most fire scars at both of our sampling locations, found at low and high elevation sites, occurred in the spring (525, 93.8%) and only 6.2% occurred in the summer. The mean fire interval and Weibull median fire interval values were < 10 years for all fire-scar filter (all samples, ≥10% and ≥ 25%), and the average per-sample fire interval was < 25 years. Conclusions: Our results suggest fire frequency has changed over time at our study site, becoming less common and less extensive since the 1950s. In addition, extensive fires occurred in dry years as indicated by low precipitation, negative NIÑO 3 Sea Surface Temperature (SST) values, and negative Palmer Drought Severity Index (PDSI) values. Fire frequencies must be maintained within the amplitude of their historical regime, with the objective of reducing the risk of severe fires and preserving ecological and hydrological benefits in the watershed.

“…Las dos reconstrucciones de precipitación obtenidas (considerando las cronologías incluidas en el PC1, como con la serie individual más extensa) indican la presencia de sequías intensas y prolongadas, las cuales han sido observadas con anterioridad en reconstrucciones de lluvia realizadas para la parte alta de la cuenca del río Nazas (Cerano-Paredes et al, 2012), así como en reconstrucciones regionales para otras áreas de los estados de Chihuahua y Durango (Díaz et al, 2002;Cleaveland et al, 2003;Villanueva-Díaz et al, 2011); donde se señalan sequías severas como las ocurridas a mediados y finales del siglo XVII , mediados del siglo XVIII (1767-1778), finales del siglo XIX (1890-1896) y mediados del siglo XX (1948)(1949)(1950)(1951)(1952)(1953)(1954)(1955)(1956)(1957)(1958)(1959)(1960)(1961)(1962)(1963); algunas de las cuales provocaron serios problemas sociales y económicos en la región, como las que se presentaron en los períodos: 1720-1723, 1739-1741, 1748-1752, 1755, 1758, 1760-1766, 1770-1773, 1785-1786, 1804-1806, 1812-1814 Los parámetros estadísticos de las series de anillo total de P.…”

Se desarrolló una red de siete cronologías de Pinus lumholtzii en la Sierra Madre Occidental para el desarrollo de reconstrucciones históricas de precipitación estacional. Los valores de los parámetros dendrocronológicos en general fueron similares a los de series de crecimiento desarrolladas con otras coníferas en esta región: sensibilidad media (0.25 - 0.38), inter-correlación entre series (0.52 - 0.66), relación señal/ruido (1.16 - 18.51) y autocorrelación de primer orden (0.01 - 0.30). El primer componente (PC1) que incluyó las cronologías involucradas se utilizó para realizar una reconstrucción de precipitación acumulada noviembre-junio en el período común de las series (1890-2001), donde el crecimiento anual explicó más de 80% de la precipitación ocurrida en dicho período; asimismo, se utilizó la cronología residual del sitio Sauz para reconstruir la precipitación acumulada de los últimos 346 años (1668-2013), la cual detectó períodos extremadamente secos (1665-1688, 1695-1718, 1767-1778, 1890-1896, 1948-1963). La respuesta de las cronologías de esta especie a fenómenos atmosféricos de circulación general, como El Niño Oscilación del Sur (ENSO, por sus siglas en ingles), también fue similar a la obtenida con cronologías de especies con probado potencial dendroclimático. La ventaja de extender la red dendrocronológica de P. lumholtzii se fundamenta en que su potencial dendroclimático es equiparable con el de especies tradicionalmente usadas con este fin; su amplia distribución y el poco disturbio antropogénico que han sufrido sus poblaciones favorece la posibilidad de encontrar individuos longevos. Por su excelente sensibilidad climática, la red dendroclimática de P. lumholtzii es fundamental para estudios dendroclimáticos, particularmente en regiones donde se carece de registros climáticos instrumentales.
