  2012 Advanced Tree Measuring Workshop
   
 
   
 
   
 
   
 
   

April 18-19, 2012

Cook Forest State Park, in conjunction with the Native Tree Society (NTS), will host a two-day Advanced Tree Measuring Workshop to the public and forest resource professionals focusing on learning the latest and most accurate methods of measuring big, tall, and noteworthy trees of Cook Forest and the Eastern United States.*   

Join members from NTS, American Forests, and Laser Technology, Inc. (LTI} as we learn various methods and accuracies of measuring trees using the traditional  tangent based methods with tape & clinometer and similar triangles, and comparing them to sine based methods using clinometer and laser rangefinder.  We will also learn the external baseline method, tripod corrections, diameter measurements, crown spread and crown area calculations with the following instruments:  LTI TruPulse 200 and 360,  LTI RD 1000 Relascope-Dendrometer, and Macroscope 25/45.
