Abstract: 

Whole plot surveys of Canopy Triming Experiment (CTE) plots were done to detect changes in the number of terrestrial fern species and individuals in response to canopy opening and debris deposition.  Surveys were conducted annually prior to and after treatments.  A count of all terrestrial ferns, identified to species on the CTE plots was recorded for each subplot in January during CTE1 (2002-2010) and in the fall during CTE2 (2014-present).  The surveys document losses of individuals of shade tolerant fern species and the appearance of open canopy ferns such as the tree fern Cyathea arborea.

Methodology

Methods: 

Each fern individual in each subplot of 12 plots is identified and counted from the between-subplot walkways annually from January 2002 through January 2010 (CTE1) and in 6 plots (Control and Trim+Debris treatments only) from October 2014 through the end of the canopy trimming experiment.  Note that because between-subplot walkways were not  included, the fern survey area within the 20 x 20 m (400m) whole plot is 353 m2 (16 subplots ca. 4.7m x 4.7m each).  Checklists of individuals present in the previous year's survey are used to determine presence or absence of previously recorded individuals and new species and individuals noted.  Note that only Block B was surveyed in January 2005 as other blocks had only been partially treated
