Krause, C. (1997) The use of dendrochronological material from buildings to get information about past spruce budworm outbreaks. Canadian Journal of Forest Research, 27(1):69-75. (Scopus )

Résumé

The history of the spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks during the last three centuries has been reconstructed by analyzing material from churches. Wood samples were taken from eight churches within a 25-km radius of Chicoutimi, Quebec, Canada. The buildings were constructed between 1864 and 1924. Sampling was realized in the basement, under the roof (loft), and in the bell tower whenever possible. All the material from the basement has been identified as Thuja occidentalis L. (white cedar), with exception of Notre-Dame Church in Laterriere, where pine beams (Pinus sp.) were found. Pine and spruce species (Picea sp.) were found in the bell tower and under the roof in all churches. Chronologics were established for the three tree species: spruce covered the period from 1672 to 1954; white cedar, from 1616 to 1924; and pine, from 1771 to 1925. White cedar was used for a nonhost chronology. To demonstrate information about past spruce budworm outbreaks, only the results for the spruce samples have been presented. Spruce chronologies for the eight churches showed an average correlation of 0.54, with the highest correlation value (0.88) registered between Satrite-Anne and Sacre-Coeur churches. All these chronologies showed clear growth reduction periods caused by defoliation of the spruce budworm. The oldest spruce chronology (1672 to 1920) from the Chicoutimi Cathedral showed two clear defoliation periods during the 18th century, one from 1710 to 1716 and the other from 1754 to 1759. The 19th century was also marked by two defoliation periods: the first from 1811 to 1813 and the second from 1835 to 1841. These periods of spruce budworm outbreaks have also been observed in the wooden structures of the other churches. A third outbreak probably occurred in the 19th century from 1868 to 1878. It is visible in the samples taken from the Chicoutimi Cathedral and Saint-Cyriac.
