Name:_____________________ Lab Section:_____ Laboratory Unit 4.1 – Ecological Methods: Field Sampling Techniques Leaf Herbivory and Fungal Occurrence on Tree Species Fall/Summer Data Collection Handout – Sampling 2 Trees Methods: Step 1: Record your observations below:  Description of sampling location(s). If using different locations, indicate and describe for each location (add GPS location/geotag, if possible): Sampled from Dorothea Dix Park; open area with not a lot of trees around. o Insert pictures:  Description of observations around each of the 2 trees sampled : They both had a bit of moss growing around the roots; tree A had black ants roaming on the trunk and other plants growing around it. o Insert pictures:

Name:_____________________ Lab Section:_____  Tree(s) Identification (as specific as possible – genus and species): Tree A is Fraxinus spp. Tree B is a Quercus alba  Other observations: o Insert pictures: Steps 2 & 3 : Record leaf surface area in the tables at the end of this document ( Tables 4.1-1 & 4.1-2)  Insert pictures of types of leaf herbivory you observe on each of your trees Chewing and mining
