This site is unique in the sense that it occurs in a chaparral habitat. A chaparral habitat is a community of plants consisting mainly of short, dense shrubs. In california, you will find a lot of manzanita, some madrone, caenothus, sage, etc. growing in such habitats. This plant community will eventually become very thick, and relies heavily on fire every 2-3 decades or so to clear out the vegetation and allow new growth to resume. Many of the seeds in this plant community will only germinate when burned .A chaparral habitat is much like a Sarracenia habitat in the sense that it relies on fire for long term maintenance. One thing notable in this population of Darlingtonias is that in previous years, there were many burnt, "sorry" looking plants. When I last visited this site in 2010, I thought it was just bad weather that's causing mechanical damage to the traps. However, upon seeing this site again in 2013 and seeing the same high ratio of burnt/dead traps, it seems like the issue is this site! Other neighboring seeps were in perfect condition this year. Chaparral communities are generally in full sun and have little protection from trees, and my haunch is that it gets too hot every summer at this site, which causes the pitchers to burn. I've seen the same thing happen to an "inland" population in Oregon that also gets full sun and seems to have sun-burnt pitchers year after year. Interestingly, these populations remain healthy, and even if the main plant dies, they send out so many stolons, it doesn't matter. Despite the heat stress, Almost every last square inch of colonizable space is occupied by Darlingtonia at this site: Overview of "cedar springs": Despite the high ratio of dead pitchers, this site is in fairly good shape-there are a lot of healthy rhizomes in there. Photos taken 10/12/13: another shot of the seep-notice how the surrounding vegegation is pretty short: A cedar branch is seen on the left of this fen: If you look in the background of this photo, notice the short shrubby chaparral habitat. Aside from the seep, this entire surrounding area is very dry: The fen flows into some thick shrubs: Did genetics cause this trap to turn a mouth-watering bright yellow, or is it from water/heat stress? This was in the middle of the "creek" so I have doubts about water stress causing this: What an amazing color! I'll have to come back in a few years and see if this thing is yellow year after year Happy traps: Weird tongue: These were looking great. The site actually looked better this year than in 2010: Some fall colors in the background-the surroundings really increased the beauty of this site : Sooooo many dead traps:
