Ecologists Discover; Climate Change Appears to Be accelerated Driving Growth Forest in Maryland. Speed is not a word typically associated with trees;
For more than 20 years forest ecologist Geoffrey Parker has tracked the growth of 55 stands of mixed hardwood forest plots in Maryland.
Forest ecologists know that the trees they study will most likely outlive them. One way they compensate for this is by creating a oechronosequence a series of forests plots of the same type that are at different developmental stages.
He and Mcmahon hope other forest ecologists will examine data from their own tree censuses to help determine how widespread the phenomenon is.
