Noticed a branch on my neighbors Alder tree is starting to change. My porch flowers and tomato plants are all slowing in their production and getting some brown leaves as if its mid September.

Wonder if the constant smoke plumes this summer have obscured enough light waves that it has tricked plants into thinking fall is early. Drought has been fairly moderate in central CO to normal in northern CO.

I've wondered that too. Drought makes sense as a possible reason in parts of the state, but not all. We've had smoke most of the summer and if the plants go on amount of sunlight they could be tricked a bit. But I think some plants go on photoperiod, which is more minutes of light than intensity of light I think - so not sure. Around El Paso and Teller counties, there are a few early signs of fall but most of the Aspen and other trees do not seem to be that far ahead - maybe a week or so....

Cottonwoods in SW Colorado are starting to turn as are the aspen up in the San Juan Mountains. I think the early change is due to drought and higher than normal normal temperatures - at least in my part of Colorado. You were correct in earlier post when you mentioned that aspen change due to length of daylight (or photoperiod). However, higher than normal temperatures and drought also can have a strong impact. While the drought has not been as severe in Northern Colorado, temperatures have been above normal in the entire state. Higher temperatures mean the trees will transpire at a higher rate and they will appear water stressed even in areas where the drought has not been as severe.

I don't know if the smoke has an impact on the color change or not - that's an interesting question. The smoke out here has certainly had an impact on me and others that I know around here. I still have an ache in my lungs from all the smoke this summer!

This picture was taken today about a half mile from Elevenmile res. Most of the Aspen are green but some areas that are turning already. I think its a little early. It was real dry here but the area got a fair amount of Monsoon moisture late in July and into August. We got rained on the hike (raining in the picture).



The pictures in the link below are all from the same area Sept 2012 - taken over the month.

Just took a Denver-Lyons-Ward-Blackhawk loop, and it was VERY nice, with the most foliage change (about 30%) between Ward and Blackhawk. Next weekend should be peak, I think.

On the front range, plants got beat up this year. A lot of plants have significant die back from the wacky rainfall pattern. We're 4.5 inches, or 40%, below average according to this source Total Precipitation for the Year in Denver

I drove Ned to Estes Park on Thursday afternoon and it wasn't anywhere close to peak except for one of my favorite aspen stands just before Ward.
The leaves are changing quickly though, I'd say around 10 days ahead of "normal".
Unfortunately many leaves are brown and dropping off. Don't think it's going to be "great" in many areas.
