It is unclear, however, how these factors influenced fire history patterns in small isolated forests, such as that found on Rincon Peak, a “sky island” mountain range in southern Arizona, USA. We reconstructed the fire history of Rincon Peak to evaluate the influences of broad-scale (i.e., climate) versus local-scale (i.e., topographic) factors on fire occurrence and extent. We evaluated both fire scars and tree demography (natality and mortality) to investigate surface fire and crown fire events. The fire history of a 310 ha study area surrounding the top of Rincon Peak was reconstructed by tree-ring sampling in 21 plots. Between 1648 and 1763, spreading fires on Rincon Peak were controlled primarily by regional climate. Widespread surface fires occurred during drought years, and were generally synchronized with regional fire events known from an extensive network of other fire history studies. After 1763, fire extent was apparently limited by local factors (i.e., fuels) as frequent fires continued to burn, but were limited to the southern part of the study area until a widespread fire occurred in 1819. Landscape fires (i.e., fires that scarred ?2 plots) were absent from the entire study area between 1819 and 1867 despite continued burning in adjacent mountain ranges. Multiple lines of evidence indicate that the 1867 fire was both a surface and a stand-replacing event that killed most trees within a 60 ha patch. Our findings suggest that past climatic variations had important effects on fire regimes and age structures of small, fragmented ponderosa pine (Pinus ponderosa) landscapes like Rincon Peak. Given anticipated climate changes, the rich biodiversity harbored in these steep, isolated landscapes will be critical habitat in the migration of species and should therefore be considered high conservation priority. # #-------------------- # Publication # Authors: Iniguez, Jose M.; Swetnam, Thomas W.; Baisan, Christopher H. # Published_Date_or_Year: 2016 # Published_Title: Fire history and moisture influences on historical forest age structure in the sky islands of southern Arizona, USA # Journal_Name: Journal of Biogeography # Volume: 43 # Edition: # Issue: 1 # Pages: 85-95 # Report_Number: # DOI: 10.1111/jbi.12626 # Publication_Place: # Publisher: # ISBN: # Online_Resource: # Other_Reference_Details: # Full_Citation: # Abstract: # Aim The purpose of this study was to examine the influence of moisture and fire on historical ponderosa pine (Pinus ponderosa Dougl. ex Laws.) age structure patterns. Location We used a natural experiment created over time by the unique desert island geography of southern Arizona. Methods We sampled tree establishment dates in two sites on Rincon Peak and another site in the Santa Catalina Mountains. The influence of regional moisture patterns was investigated by examining synchrony among tree age peaks and periods of favourable moisture. The influence of fire was investigated by examining the relationship between local fire histories and age peaks. Results Tree age peaks (recruitment events) were synchronized with periods of reduced fire frequencies, suggesting that periods of reduced fire activity allowed time for young trees to develop fire-resistant characteristics. For example, two age peaks (1670s–1680s and 1770s–1780s) in the Rincon Peak-north site coincided with a period of reduced fire frequency. These age peaks were absent in the Rincon Peak-south site where fires were more frequent during that time. All three sites had age peaks in the early 19th century, coinciding with regional climate variability (i.e. El Niño Southern Oscillation patterns) that reduced fire activity. Main conclusions Historically prior to fire suppression, the survivorship, and thus cohort establishment, of ponderosa pine was ultimately determined by local fire history patterns. The importance of fire as a tree establishment regulator highlights the need to use fire at appropriate intervals not just to restore but to maintain healthy forests. # #-------------------- # Site_Information # Site_Name: Rincon Peak RP06 - IMPD USRPK_06 # Location: North America>United States Of America>Arizona # Northernmost_Latitude: 32.12493 # Southernmost_Latitude: 32.12493 # Easternmost_Longitude: -110.52263 # Westernmost_Longitude: -110.52263 # Elevation_m: 2262 #-------------------- # Data_Collection # Collection_Name: USRPK_06 # First_Year: 1472 # Last_Year: 2004 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: fire scar dates # Notes: #-------------------- # Species # Species_Name: Pinus ponderosa Douglas ex C.
