Stockton's Regeneration Project |
In 1988, Richard Stockton College funded a pilot study to investigate the current research and extent of knowledge regarding Atlantic white-cedar in New Jersey.
In 1989, the New Jersey Department of Environmental Protection Funded a small study to further explore white-cedar research.
In 1990, Professor Zimmermann received a grant from the N.J.D.E.P.'s Division of Science and Research to begin a five year comprehensive study of methods to regenerate white-cedar. Additional funding has been provided by the United States Forest Service and N.J.D.E.P.'s Division of Parks and Forestry's Bureau of Forest Management.
The study concentrated on four factors thought to influence white-cedar regeneration:
1. Deer browsing: Browsed cedar seedlings |
2. Adequate supply of cedar propagules: Cedar seeds |
3. Competition from other vegetation: Herbicide spraying | |
4. Effects of logging slash: Logging slash | |
The study would manipulate these major factors in the following scenarios thought to contribute to the demise of white-cedar along its geographic range.
These scenarios and the sites chosen are:
FAILED CLEARCUT (the Colletti site)
SWAMP HARDWOOD CONVERSION (Belleplain, Bass River and Jackson sites)
ILLEGALLY LOGGED / DISTURBED SITES (the Three-foot site)
RECENT CLEARCUT (the Penn Swamp site)
