"DON'T BE A SAP, KNOW YOUR OAKS CALIFORNIA NATIVE OAK TREE IDENTIFICATION KYLIN COSTA
STANDARDS ADDRESSED: G1.1 (Understand how to classify and identify plants by order, family, genus, and species) G1.3 (Understand how common plant parts are used to classify the plants)
BACKGROUND The Oak Tree is the National Tree of the US CA has over 20 native species of Oak trees Oak trees, especially the Coast Live Oak, provided a source of food and shelter for Native Californians Many counties (including Santa Barbara and San Luis Obispo) currently have Oak Tree Conservation Laws Oak Trees can be deciduous or evergreen
FIRSTTHINGS FIRST: PARTS OF AN OAK TREE CROWN: Contains leaves which allow trees to perform photosynthesis Produces fruit in the spring, known as ACORNS Home to many species of birds TRUNK: Helps transport water up into the leaves, and sends nutrients out Connects the crown to the roots ROOTS: Absorbs water from the soil up into the tree Oaks can absorb up to FIFTY GALLONS of water per day
LOOK AT THOSE LEAVES! Let s TRY IT! FIRST, what season is it? What COLOR are the leaves? Then, observe the LOBE: Are the edges round? Are they pointed? How MANY lobes are there?
COAST LIVE OAK (QUERCUS AGRIFOLIA) Location: Hills on the Coast of CA CHARACTERISTICS: EVERGREEN GROW TO BE 25 METERS TALL CAN LIVE TO BE OVER 250 YEARS OLD LEAVES ARE POINTY AND CURVED SMALL ACORNS WITH SCALY CAPS
VALLEY OAK (QUERCUS LOBATA) CHARACTERISTICS: Winter-deciduous Leaves have rounded lobes and deep valleys Tallest CA Oak Tree Can grow to be 36 meters Bark on trees reflects that of alligator skin Acorn is LARGE in size
BLUE OAK (QUERCUS DOUGLASII) LOCATION: CHARACTERISTICS: Deciduous Also known as the Iron Oak Medium Sized Tree Soft, rounded leaves Bark can appear to be a blue/white
INLAND LIVE OAK (QUERCUS WISLESENI) LOCATION: NATIVE TO BAJA CA and INNER COASTAL RANGES CHARACTERISTICS: Evergreen Grows to be around 22 Meters Almost black bark Medium sized acorns Often found near Blue Oak
WHY ARE OAK TREES IMPORTANT? Oaks are an excellent method of erosion control They provide shade and shelter to many pasturelands and ranches across CA Wood is used for famous Oak BBQ Over 300 species of wild animals call oaks home
APPLY IT! What is your plan for making sure that Oak Trees remain a significant part of California s landscape?
