Site Description
Location: Eaton Canyon Park
Habitat:Grassland
Dimensions of site: 10 paces x 5 paces
In our observation site the ground was covered with many dead branches and leaves. Some rocks were scattered around the area, but many were to small to sit on. The area we were seated on had no canopy due to it being an open area. Our observation site was very peaceful and quiet with very few animals wandering by. On our way to the observation site we stumbled upon many plants and animals such as Poison Oak (Toxicodendron diversilobum) which in our case, had reddish-brown leaves connected to branches protruding from the ground. Other plants include Bush Sunflowers (Encelia californica) tiny, small yellow flowers with a brown middle, Buckwheat (Polygonaceae) a shrub with small white flowers at the tips of the stems, White Sage (Salva apiana) a shrub with white-covered green leaves that smelled like sage, Chamise (Adenostoma fasciculatum) a shrub with leaves that looked like small pine leaves. Some animals that we saw were the Side-blotched Lizard ( Uta stansburiana ) Sandy looking lizard with tiny white spots scattered on his back. At our observation site we encountered Black Mustard (Brassica nigra) a shrub with bright yellow flowers at the tip of the stem, Pine Goldenbush (Ericameria pinifolia) a shrub with pine looking leaves coming from every which way on the stem, Whipple Yucca (Yucca whipplei ssp. parishii) a shrub with needle-like leaves radiating from the center (some forms had a dried out stalk with seeds at the top on it), Laurel Sumac (Taco Plant) - (Malosma laurina) a tree with taco shaped leaves and dried out flower bunches. Some animals at our observation site were the Honeybee (Apis mellifera) flying bug that is yellow with black stripes. Can sting you if bothered, Side-blotched Lizard ( Uta stansburiana ) sandy looking lizard with tiny white spots scattered on his back. There was some evidence of birds in the area because they could be heard chirping.

Pine Goldenbush
This is a picture of a pine goldenbush taken at our observation site. This picture was taken on 10/29/12 at 12:12 military time at Eaton Canyon. The pine goldenbush is a native plant with needle like leaves that smell like sage. This plant can grow up to 6 feet tall. As you can see in this picture the plant is dried out.
Laurel Sumac
This is a picture of a Laurel Sumac tree. It was taken on 10/29/12 at 12:07 military time at Eaton Canyon. Under this tree is where we found the geocache box. This tree is a native shrub and can grow up to 7 feet tall. The leaves are slightly folded and has sap that can sometimes irritate the skin.
Whipple yucca(after nine years)
This is a whipple yucca after it has been living for nine years or more. This photo was taken on 10/29/12 at 12:06 military time at Eaton Canyon. This is the same plant as the green spiked leaves plant as pictured before on this blog. The only difference is that this plant has aged nine years or more and died. After nine years the stalk grows from the plant and sprouts seeds. The plant then dies, turning a yellowish color like in this picture.
