When we had llamas, there was a lot of interest in these wonderful animals — and some of that interest had to do with how much money you might be able to make with them. After some years, the big money mostly moved on to alpacas. As a result, many people lost interest in llamas. This is reflected in the selection of websites, as many have not been kept up much.
By far the best website I have found for current information on llamas and alpacas is called llamas-alpacas.com, publisher of The International Camelid Quarterly, a full color, high-quality magazine on llamas, alpacas, and other camelids. I know some of the writers from way back, and they are good. You can subscribe online only or for the physical magazine too.
One of the few websites that is current is that of LANA, the Llama Association of North America. They have an active youth program and other events.
Another organization currently active is RMLA.com — the Rocky Mountain Llama and Alpaca Association, mainly in Colorado. They publish the excellent Caring for Llamas and Alpacas, by Clare Hoffman, DVM, and Ingrid Asmus — that link takes you to their page on it.
Llama.org is done by a group that may no longer exist, I’m not sure: the Llama Lifestyle Marketing Association. The site has a section about what you can do with llamas. It says the last update was 2007, and I see quite a bit that was already out of date then. The parts about making money with llamas are out of date for sure.
Llamaweb.com doesn’t seem to have been kept up since 2005, or at least they haven’t updated their copyright since then, but here is a good section of facts about llamas. There are quite a few pages, including one on coat colors.
Here’s a page of information about llamas at North Dakota State University. It seems to have been written in 1993, but the essential facts are current. The prices of llamas are probably not. This has a lot of the kind of thing that is useful in school reports.
To find llama ranches in your area, do a google or other search engine search on llama ranch (singular) and the name of your state or region.
