Forms for collecting data for the tree study
This is where the rubber meets the road. These forms are the meat of the study. If you are one who loves trees and want to be part of a project that should add a new tool to the Winter Tree Identification tool kit just print out what you need in the way of forms and get out there in the woods, parks, along roadways, yards, streets or whereever trees are found and observe. Happy hunting. I will feel a kinship with you as I am doing the same here in beautiful rural South West Virginia.
Click on the links below to bring up the PDF copies of the forms and you can print out what you need for the study... or click on any of the forms in the full set for the full set of PDF forms or click on the Data Collection From at the bottom for that form only.
Back of the expanded Data Collection Form I use which includes the worksheet for measuring tree height.
Using the sextant method: The Sextant Method
Using a photo to measure tree height: Measuring a tree from a photo
On my expanded form I refer to the photo method as the ImageJ method. This is because I use a program by that name which does the same thing as I explain in the illustration of measuring a tree from a photo.
For those of you who want an extra challenge, I use an extended Data Collection form for my work which includes measuring the height of the tree. For that work I use a sextant I modified to allow me to measure the angles from level up to the top of the tree and level to the bottom of the tree. I use a small laser ranger to determine the base line (distance from me to the tree) and with that information I can solve for the height of the lines ground to level and level to the top of the tree. I also check the pH of the soil. These measures are not required of you but if you would like to get adventurous and go the extra mile click on the link below to print out the expanded Data Collection Form (front and back) and enjoy.
