Do live oaks ever stop dropping leaves?
Live Oaks Have a Leaf Exchange in Spring For many trees, dropping leaves is a way of preparing to go dormant during the cold winter months. Live oaks, however, can lose leaves throughout the year and generally stay green during the winter.
What is the difference between an oak and a live oak?
One main difference between a live oak and a run-of-the-mill oak is that a live oak is evergreen — almost. It does drop some leaves in the spring but quickly replaces them to keep that photosynthesis thing going. That gives them a dense canopy so they work well as shade trees.

What is the history of oak trees in California?
The history of oaks in California is long and storied. Oaks have long had a place in Californian culture. We celebrate these trees that once covered a third of the land in the names of our cities, towns, and schools (think Oakland, Encino, Paso Robles, Live Oak High School...the list goes on). The native oaks of California once dominated the landscape. Accounts of Spanish explorers mention their awe at the sight of the abundance of oaks around them. However, those with the strongest connection to the oaks of California were and are indigenous people.

Why were oak trees important to the Ohlone?
The oaks were also vital to the Ohlone as markers for the changing of seasons. They were able to develop a sense of time by watching the changes in the oak trees such as the arrival of buds, flowers, and acorns as well as the loss of leaves in some species. This would tell them when animals, such as bears, would be coming to gather acorns and have their share of the feast.
What did the Spanish do to the oak trees?
The Spanish introduced grazing animals and felled oak forests to make room for their agricultural enterprises. They also saw value in the lumber of oak trees, leading to even more deforestation. Before the native people could do anything to prevent them, the Spanish had dramatically damaged the relationship between the people and the oaks. Tribes like the Ohlone could no longer rely on the acorn as their primary food source and were forced to go to missions which actively discouraged and punished their traditional ways of living. Being forced into the Catholic way of living as a means to survive without their once plentiful native lands severely disrupted the Ohlone people and their connection to the land. Nowadays, many of their descendants view the oak tree and acorns as a reminder of their past and the traditional values that were stripped from their ancestors.
What are the natives of Santa Clara Valley?
The people native to Santa Clara Valley are known as the Ohlone, which is a name that encompasses 50 separate tribes ranging from the South Bay all the way down to Monterey. Native oaks of California are ingrained in their society as a resource both physically and spiritually. Acorns were the primary food source for the Ohlone prior to the arrival of the Spanish and were held in high regard amongst the native people. Anthropologists estimate 75% of native Californians relied on acorns in their daily diet. Their new year, a joyous occasion, was marked by the acorn harvest. The Ohlone people would dance amongst the oak groves each year to promote a good harvest. During the acorn harvest, entire families would go out and collect the acorns of a large tree, which took about a day. The women would then prepare the acorns by shelling them and using a mortar and pestle, grinding the acorns into a fine powder. After being ground, the acorn flour would undergo the lengthy process of leaching the bitter tannins from the acorns which made them unpalatable. After the tannins were leached, the acorn flour was much sweeter and easier to eat and could be used to make soups, mush, and even bread (I myself love acorn bread). Excess unground, shelled acorns could be stored up to 10 years. The preparation of acorns was not just fulfilling a necessity. It was also a time for social connection during which the women could talk amongst themselves and share stories of their lives and even gossip.

A: The rings on a tree are called growth rings and they are used to determine the age of a tree. They are made by the trees vascular cambium, which is the layer of cells that transports water and nutrients from the roots to the rest of the tree. As trees grow, their vascular cambium produces new layers of cells in between each ring. These new cells contain more carbon than older ones, so when you look at them under a microscope, you can
Why is it advisable not to sleep under trees during night?

The convex leaf shape may be useful for interior leaves which depend on capturing reflected light scattered in random directions from the outer canopy.

How much land does California have oak trees?
It is estimated that one or more species of oaks grow on over 20 percent of the state’s 100 million acres of land. Unfortunately, there are also reports that some native oaks may not be regenerating very well in some locations. Poor natural regeneration raises concerns about the long term fate of these species. To assist Mother Nature in establishing new oak trees, efforts are underway to plant acorns and small seedlings. Such regeneration efforts will ensure that our magnificent oaks, which have graced California valleys and foothills for thousands of years, will be around for future generations to enjoy also.
Why are oak trees important to California?
They grow in a wide variety of habitats and help provide a distinctive character to the landscape. Not only are they beautiful to look at, but they also provide food and shelter for many wildlife species, they stabilize soil, and they help counteract the “greenhouse effect” by taking up carbon dioxide and producing oxygen.
What animals eat acorns?
As the seedlings start to grow in the spring, there is a also a chance that their tender young shoots will be eaten by livestock, rabbits, grasshoppers, or other animals. The risk of such injury to both acorns and seedlings can be reduced by placing protective cages around the planting spots. One type of cage that has worked well in research plots consists of an 18×18-inch aluminum screen that is formed into a 5-inch diameter cylinder and stapled to a 1x2x24-inch wooden stake. The cylinder is folded closed at the top. The stake is driven into the ground so that the screen cage covers the spot where the acorn or seedling is planted. This cage will keep out rodents, insects, and browsing animals.
How to store acorns before planting?
They should come off easily when twisted. Acorns collected directly from the trees should be put in plastic bags and immediately placed in a refrigerator. Refrigeration slows the metabolic activity and helps prevent them from heating up or drying out both of which can be damaging. A recent study indicated that storing acorns in a refrigerator for a month or so before planting resulted in faster and more complete germination than planting acorns immediately.
How to grow acorns in a hole?
Plant the acorns one-half to one inch below the soil surface. Dig a hole using a hand trowel, hoe, or shovel. It’s best to dig the hole several inches deeper than the acorn is actually planted, and then partially fill the hole back up with loose soil. This gives the new root a chance to get a good start in soft, easy to penetrate soil. If the acorns have germinated, try not to break the root tip, and position it in such a way that the root is pointing down. Even if the tip of the root has begun to turn brown, the acorns should still be okay as long as some of the root is white and fleshy. Place ungerminated acorns on their side in the hole and cover with soil.
How to pick up acorns?
Those that fall to the ground often dry out and are damaged especially if they lie exposed for more than a few days during hot and dry weather. If you do collect acorns from the ground, leave behind those that are very small, cracked or feel light and hollow. Acorns collected directly from trees can be hand-picked or knocked to the ground using long poles or pieces of plastic pipe. It’s easy to pick them up if tarps are placed under the trees first.
How to store acorns?
“Floaters” are generally acorns that have been damaged by insects or have dried out while they were on the ground. “Sinkers” should be saved. Remove the acorns from the water and place them on cloth or paper towels for a half hour to dry their surface. Then place the acorns in plastic bags in the refrigerator. Check them occasionally for molds. If molds do develop, take the acorns out and rinse them, and then put them back in the refrigerator. Leaving the plastic bag partially open at the end seems to reduce the tendency for molds to develop.
