The Redwood Forest
Transcript of The Redwood Forest
strong seasonal variations with short moderately warm
and moist summers and long extremely cold and dry
winters. Because of this, animals and plants have developed adaptations to survive. Here are examples: black bears eat A LOT of food before winter and when the winter comes they hibernate. Another example is the nuthatch. This small bird has a special beak to help him eat the inner parts of the pine cones. The giant redwoods have special needles that preserve moister and water for the winter. In conclusion because of the weather the animals that have the best adaptation will survive better. BY: Dr. Krishnan Castillo Partners: Cooper Barnett, Jefferson Lan Hu, Javier Toledo, Gabrielle Lattimer Region of the Redwood Forest I am studying the redwood forest of North America NOT the other redwood forests of the world. The average temperature in summer is 57.2 F. In winter it is 14 F. The average annual precipitation is 14-29.5 inches. The redwood forest has 4 seasons; summer, spring, fall and winter. Certain air currents pass over the redwood forest. Most of the currents are 1 C but they get warmer because of the sunlight. There are small currents of 0.2 C, 0 C, -1 C and -5 C. The elevation of the redwood forest varies in between 1500 ft. and 2000 ft. Temperature Graph Precipitation Graph The redwoods are the tallest and most ancient trees of the world! The redwoods are so thick that your car can pass through them! Location of the Redwood Forest The Redwood Forest is located in the western coast of North America. It is in the United States "passing over" the states of California and part of Oregon. The forest is located between the 40 N line and the 45 N line. It is in the 120 W line. Remember, there are more Redwood Forests in the world. California's is not the only one. In California the Redwood Forest is being
protected A LOT! The latitude lines are something that can realy change how the redwood forest is. They determine the closeness to the equator and the poles which changes temperature, precipitation and climate. Because the redwood forest is located in the 40 N line it has very cold winters and mild summers. The longitude lines determine the closeness to the oceans and the neighboring cities. If a forest is very close to an ocean it is going to be humid and moist. If a forest is close to a big city the air is not going to be as clean as it could be. The redwood forest is not very close to an ocean so it is not very humid or moist. The redwoods are pretty close to not very big cities, so the air is not heavily polluted. The altitude of where the forest is located determines the temperature and air pressure. If a forest is located on a high altitude it is going to be very cold. Also, if a forest is located on a high altitude there is going to be less air pressure which is going to make the plants and animals adapt. The redwood forest is located in between 1500 ft. and 2000 ft. That is very cold climate. The proximity to bodies of water determines the humidity, moister and plants of a forest. If a forest is close to a body of water it will make the forest moist and humid. Lots of plants and trees will grow because of so much water. The redwood forest is not located next to a big body of water. However, small streams and probably rivers make lots of plants and trees grow in the forest. Landforms Affect the Redwood Forest Temperature Affects the Redwood Forest The average temperature of the redwood forest is 35.6 F (of the year). Temperature affects a forest by changing how plants grow. If plants grow TOO slow herbivores are going to die so carnivores are going to starve to death. The temperature affects the redwood forest by manipulating how the plants grow and weather changes. It affects how fast birds migrate and how animals and plants adapt. The changes of seasons can also be affected by the temperature. The humidity is another factor. Weather Affects Animals Region of the Redwood Forest Temperature Graph Precipitation Graph Location of the Redwood Forest Landforms Affect the Redwood Forest Temperature Affects the Redwood Forest Seasonal Changes in the Redwood Forest The temperature changes dramatically over the seasons. For example, the average temperature in summer is 57.2 F and in winter it is 14 F. In spring it is 43.25 F. In fall it is 37.85 F. The precipitation also changes dramatically over the seasons. The average precipitation in summer is 55.25 mm. In winter it is 27.5 mm. In spring it is 35.5 mm. In fall it is 30 mm. According to what I already know (don't take what is say too seriously) there is less sunlight in summer than in winter because in summer there are a bunch of clouds but in winter normally the sky is clear. I don't know much about fall or spring but I THINK that in spring there are a bunch of clouds in the sky so sunlight doesn't get through too easily. Probably in fall there aren't much clouds; just like in winter. Now, talking seriously winter days are shorter so less sunlight can come through. In summer however, days are longer so MORE sunlight can get through. In spring days are "normal" and in fall days are shorter. The redwood forest is covered in snow for most of the year, mostly from Ocober to May. Otherwise, it is very cold even in summer. The snow melts a little in summer and spring. The snow begins "being made" in fall.

-Dr. Castillo Interesting Information The redwood forest is known to be the oldest forest in the planet. It is estimated the forest is more than 700 years old! A redwood tree can leave more than 400 years! For that reason they're being protected a lot. Their wood probably is as strong as metal poles!
