I'm so glad I stumbled upon this video. Amazing resource that's been helping a lot with my project for my masters degree in Social Anthropology (urban forestry as a local response to a global problem: global warming). Thank you for all your great work, Mr. Arroyo, greetings from Mexico 🇲🇽 !

Do you know a university in the USA that offers courses or a training program for three months in grasslandad or perennial forage crops managment? I am a farming engineer from Argentina, and I am working in this field. My wish is to improve my Knowledge in this area. Thanks a lot again!

Thank you for uploading this! I've been working in the Sierras this summer with spotted owls and I'm happy to finally understand the fire ecology of the area. I've been spending some time now searching for the illustration that describes conifer species relative to elevation, but can't find it. Do you know where I can still find it?

Very helpful Sir, but I would like to ask, how do you know that there are two different parent materials on a certain soil profile?
@renaldoarroyo7069
@renaldoarroyo7069 2 жыл бұрын
It would be obvious in the look of the soil. The way the horizons would form would only make sense if it was two different parent materials. The other idea is that the history of the area makes sense for that (like an area that was not in a floodplain eventually became part of a floodplain, the previous soils would be covered up and you would eventually end up with a two parent material scenario.
