Dendroclimatological observations on trees at Kew and Wakehurst place: event and pointer years
1996
Bridge, M.C. | Gasson, P.E. | Cutler, D.F.
The growth responses to varying meteorological conditions of a number of trees grown at Kew Gardens and Wakehurst Place are investigated. Event years for each tree-ring series are identified and then pointer years for all trees recognized and related to weather records. The use of pointer years has highlighted the similarity in growth characteristics throughout a range of taxa in the more extreme years. The strongest pointer year, 1958, coincides with a warm wet summer. Narrow rings generally correlate well with known periods of agricultural drought for the trees grown at Kew. Response functions for oaks and hickories are also presented. Several individual Kew trees have growth patterns which cross-match with oak site chronologies from southern England using standard dendrochronological techniques.
