The first verifiable reconstruction of spring ( April July) precipitation is presented for Crimea, Ukraine. It is derived from Crimean pine ( Pinus hamata) ring- width data spanning A. D. 1620 - 2002. The reconstruction accounts for 37% of the variance in observed precipitation over 1896 - 1988. Most droughts recorded in Crimean historical documents in the 17th - 19th centuries coincide with below- average reconstructed precipitation in the concurrent or following year. An 11- year filtered version of the reconstruction correlates with an annually- laminated sediment- thickness record from Saki Lake ( 4188 years in length), once this record is shifted backward by 15 years. The offset may be explained by anthropogenic changes at the lake in the late 19th century. The significant relationship between the lake sediments and reconstruction suggests that the lake record is also a moisture indicator. If so, the wettest period of the past 1500 years ( similar to AD1050 - 1250) broadly coincides with the " Medieval Warm Period'' ( MWP) in Crimea.
