Chapter: Herbs

AKA: Larrea divaricata, Larrea tridentata.

Effects: Contains nordihydroguaiaretic acid (NDGA), a chemical which has shown antioxidant and antiseptic qualities. Traditionally used by Native Americans to treat various cancers, arthritis, bruises, eczema, rheumatism, snake bites, venereal diseases, and wounds. Herbalists have used it as an antibiotic, treating bacteria, viruses, and parasites. Used as a mouth wash, it can reduce cavities by up to 75 percent, though all of it should be spit out immediately after rinsing the mouth, as swallowing could produce side effects.

Precautions: Scientific evidence for any claims is lacking. The plant could cause inflammation of the skin if touched. Internal use may cause damage to the liver, especially if taken in large doses or for prolonged periods of time.

What is the difference between grassland, chaparral and desert biomes?, What is the difference between grassland, chaparral and desert biomes? I really don't understand the difference between the former two; they seem pretty similar to me.


Desert biomes would be similar to the tundra... The desert has minimal vegitation. The grassland supports tall grasses and short grasses. The chaparral is the inbetween biome. All three biomes are determined on the amount of precipitation they get. Grasslands gets more than chaparral and chaparral gets more than desert.

I hope this helps

What is a specific decomposer in a chaparral biome?, Need help for my biology project im making a food web and i need to know a specific decomposer from the chaparral biome.

coyote( is not so much a decomposer, but an oportunist) , earthworm, fungi, millipede, vulture, mouse

Fire-sensitive plants: a threat to the chaparral biome?, An invasion by fire-sensitive plants is a threat to the chaparral biome.
What does it mean to be “fire-sensitive”? Could someone please explain why that is?

Fire-sensitive plants are easily inflammable, most often they contain essential oils like junipers f.e.
In the chaparral biome and its hot dry summers are these plants dangerous for all the other flora, because of the densely-growing vegetation, the heath of a burning juniper would inflame even a normally fire resistant dry shrub.

What's the difference between true chaparral and coast chaparral?,

I've lived in SD- CA.... so.....
coastal chaparral have vegetation that is is 'used' to not being frozen over at all and are accustomed to weather that DOES NOT reach over 90 degrees or so....
so that means vegetation in a coastal chaparral ecosystem does not have to 'worry' as much as their other counterparts about things such as trying to conserve water as tightly as their other counterparts..though they are developed with being able to store water through the dry months...

Does anyone know some statistics on the Chaparral forest?, I need to know anything about the dirt, pollution, or at least a website I could check out. Please help!

This site looks like it has some useful stuff.

Which of the following characterizes both the savanna and the chaparral?, I originally had five choices but I narrowed it down to A.) Periodic Fires and B.) Extensive stands of trees, I've been leaning towards fires

Periodic fire s an ecosystem native to central North America, with fire as its primary periodic disturbance. In the past, tallgrass prairies covered a large portion of the American Midwest, just east of the Great Plains, and portions of the Canadian Prairies. They flourished in areas with rich loess soils and moderate rainfall of around 30 to 35 inches (760 to 890 mm) per year. To the east were the fire-maintained eastern savannas. In the northeast, where fire was infrequent and periodic blowdown represented the main source of disturbance, beech-maple forests dominated. Shortgrass prairie was typical in the western Great Plains, where rainfall is less frequent and soils are less fertile.

How will the destruction of the chaparral biome affect global warming?,

good question....i dont think it will have much of an affect except in the form of positive and negative feed backs.....if the chaparral biome is destroyed and doesnt exist then that means there will be less fuel for wild fires in the western us as well as other areas like australia. this means with less fires that less CO2 would go up in the atmosphere and it could possibly slow down emissions from that sector specifically....

so other then that i dont see it having much more of an impact unless a new biome replaces it and thus either takes out more CO2 or less...

hope this helps

Can Anyone Find a worldwide distribution map of the chaparral biome?, Please!
Everywhere only has California
But I need a worldwide distribution mapr for my project!

Ought to help...I would also suggest doing a google search for "world biomes" or something similar.

Good luck!

What are some Decomposers of the Chaparral Biome?, Please list a link where i can find this information.

Bacteria, fungi and mold.

What is a fair price to pay for a 2004 Chaparral SS180 ?, I am looking to buy an 18 footer and this one is on a trailer an is mint.. Probably seen water 5 times (fresh water). Of course my friend tells me, offer what you think is fair.. Any ideas ?

I looked online at but there was only a 23 listed. To get a good idea go to the library and ask for the BUC books. They list values of all boats and years. You will get the base value and then add on for mint condition, low hours and fresh water use. I use them all the time for marine surveys.
