This was our first excursion up into the Upper Arroyo in Pasadena. The goal of this outing was to observe the space similarities and differences of plant communities.
This trip into the Lower Arroyo in Pasadena sought to observe and note examples of local geology, human activity and the use of the landscape by past indigenous peoples.
This was the fourth trip into the Lower Arroyo in Pasadena with the goal/purpose to observe and broadly measure the different species in several biomes.
On this outing to the Lower Arroyo, as a group the naturalist class moved down the trail through the riparian and chaparral area into the sage scrub open space.
