I live in Shingle Springs, a small town in the Sierra Nevada foothills, elevation about 1300 ft. The terrain is grey pine chaparral/ oak forest...the weather had been unusually warm when about a dozen dark brown/black morels of varying sizes popped up between the burn pile and the garden...I was unfamiliar with them, but thanks to Google and this website, I had a tasty dinner of sauteed morels with cream sauce and pasta - Yum! My family thought I was going to keel over dead from eating something out of the yard, hehe!

So do morels appear frequently at burn sites? Is there a chance of finding more on this property (5 acres)?

well, if you haven't found more already, yes, it is likely that the same patch of morels will produce more both this year and following years. This is because they grow from a common mycelium, kind of like an aspen grove. Burn sites are great, but like all morel habitats, the season is largely controlled by the weather- moisture and warmth are key! It could last two days or over a month depending on weather. Be sure to look for different kinds of morels, black, yellow, etc., as these grow at slightly different times
