Ash Seed Collection

On top of a semester already full of classes, schedules, meetings, writing, and data analysis, there is still a little more field work. Now is the time for seed collection of ash trees and Rachel was able to get some help with this from the Forest Service. They went out to collect seeds from the few remaining adult trees in the area.  Many of them have produced seed, but the embryos inside were not fully developed. This can happen for a variety of reasons: the wrong type of weather occurring at the wrong time (spring frost), tree stress (EAB beetle), or golls (parasites creating the flower or seed into a home).  Also, there are male and female ash trees so they cannot fertilize themselves.  If the males and females are not close enough together the pollen from the males cannot fertilize the female flowers on the tree. Here are a few picks of the process and trees:
First is a pic of the extendable pole pruners (yellow), which are very handy and kinda heavy.
 Then this is a branch that has seeds and flowers that have a goll formation
 And one of the seeding trees next to the creek
