Advanced Tree Measuring Teacher Workshop

Cook Forest State Park will host a two-day Advanced Tree Measuring Workshop on 7/26-27/18 for teachers focusing on learning the latest and most accurate methods of measuring big, tall, and noteworthy trees such as those found at Cook Forest State Park. 


This intensive two-day tree measuring workshop focuses on using laser rangefinders, clinometers, macroscopes, tapes, and poles to accurately measure trees to high tolerance levels.  Day 1 will focus on learning the use of various methods and tools.  On Day 2 we’ll apply lessons learned the previous day by hiking to several of the park’s largest trees to acquire their latest measurements.  This is an excellent workshop for math teachers looking for practical math application in the field.  Be prepared for off-trail vigorous hikes to view and measure the following noteworthy trees:

     Longfellow Pine - tallest known tree north of the Great Smoky Mountains

    Seneca Pine - state champ white pine, largest known pine in the state

    Susquehannock Hemlock - state champ hemlock, largest hemlock by volume in the Northeastern U.S.

    Davies Memorial Black Cherry - state champ black cherry, 2nd tallest known in the Northeast
