As you can see from my two photo gallery postings the changes in my phenology spot mostly consisted of leaves falling off of trees. Other than that the large dead logs in my area became far more rotted and lost a lot of biomass as time passed. I believe that, due to the action of woodpeckers, which i have seen in my area a number of times, the trees got very wet on the inside due to deep holes drilled by the crafty little buggers and therefore were susceptible to rotting and decaying. Thats why they lost so much mass over time as opposed to regular dead trees. As the leaves fell off the trees they gave back to the landscape. Simply put, they returned the nutrients they had once taken and utilized from the environment in the circle of life. As the trees lost their leaves, more sun could reach into my phenology spot changing the feel of the place entirely. As it got colder, the light got warmer.
