Abstract

The temperature of the ground depends on the angle of the sun, the amount of shade, the ambient air temperature, and the amount of time the area has been in sunlight. As a result, oak woodland sites, chaparral sites, and Riparian sites should all record different temperatures as they all experience different levels of sun, shade, and air temperature. In addition, each areas has different The question is, however, is “How Does Ground Temperature change Between Oak Woodland, Chaparral And Riparian Sites At Eaton Canyon?” Answering this question will help biologists know where replant endangered species and will help firefighters understand what areas are at higher risk of wildfire.

Eaton Canyon located in the hills above Altadena, CA was founded by Judge Benjamin Smith Eaton. The canyon was previously referred to as El Precipicio bh Spanish settlers because of its steep walls. In Summer,, Eaton Canyon’s has an average high in the 90s while heatwaves can push temperatures to near 115 degrees. On winter nights temperatures regularly drop below 45 degrees, with some nights cooling below freezing. Due to being located the windward side of the San Gabriels, Eaton Canyon received more rainfall than most areas of Los Angeles County. While the canyon averages 20 inches of rain a year, a year of average rainfall is rare with very dry winters following wet ones. Eaton Canyon is also known for its waterfall, which people essentially hike to. The Eaton falls flows into the Rio Hondo River and ends up in the Los Angeles River. Knowing that there are water flows throughout different areas of Eaton Canyon, the temperature of the soil can vary.

Summary of research results to be presented

We will be using a Ryobi IR002 Infrared Thermometer to record ground temperatures between the Eaton Canyon parking lot northwards towards the waterfall. We will find 15 sites for each biome site to use for our data points. In Chaparral sites, which are shrubby regions away from riverbeds, we will record ground temperatures in the sun. In woodland areas, which are regions near rivers with large oak trees, we will record ground temperatures that are in the shade. At Riparian sites, which are riverbeds, we will record ground temperatures in sections of dry riverbeds where large boulders are not present. At each site, we will hold the button down and take 5 readings. We will then use the hottest recorded reading for the ground temperature of the site. We will use a Garmin GPSMAP 2 the records the geographical location of each site. With this information, we will find the average ground temperature of each biome, compare the temperature from the different biomes, and analyze which is warmest and which is the coolest.
