Abstract

Using a 545-year ponderosa pine (Pinus ponderosa) tree-ring chronology, the AA. examine the drought history of central Oregon to : 1) determine the relationship among drought, ENSO (El Niño Southern Oscillation), and the PDO (Pacific Decadal Oscillation), and 2) compare the climatic sensitivity of ponderosa pine and western juniper (Juniperus occidentalis) to determine their suitability as interchangeable climate proxies. The climatic reconstruction explained 35% of the variance in historical Palmer's Drought Severity Index (PDSI) values and revealed severe drought periods during the 1480s, 1630s, 1700s, and 1930s
