Prime time for Colorado fungi

FRISCO — For a couple of weeks every summer I need to set aside extra time every few days to search for wild mushrooms. It’s not just the eating — I’m totally fascinated by the role fungi have in forest ecosystems, with some recent studies suggesting that they may be the key drivers of the forest carbon carbon cycle because of how they interact with plants to sequester carbon deep in forest soils. This morning, during a short walk in the Tenmile Range, I found one decaying section of a log, about two square feet, home to at least six species of fungi (that I could see), along with many more types of moss and lichen, all woven into a living, organic mat on the forest floor. And, as icing on the cake, I did find a couple of Boletus edulis, delicious edibles sought after around the world under various names, including porcini and cep. Continue reading

Summit Voice: Weekly roundup

Water wars, chapter 33?

A new study spells out environmental impacts of new diversions from the Colorado River Basin.

By Bob Berwyn

The tug of war over western water is a never-ending source of fascination and a vital topic for everyone in Colorado. In the past couple of weeks, water users on both sides of the Continental Divide have started digesting details of a massive environmental study that spells out the impacts of new diversions from the Fraser River, a key headwaters stream in the Upper Colorado River Basin.

The story is complex and deserves in-depth and sustained coverage. I took a stab at an overview for the Boulder Weekly after talking to some really smart people about how the proposed Moffat Tunnel Collection System expansion might play out. Will there be enough common ground? Or will the push to take even more water from the Colorado spur an all-out water war?

One thing is for sure: Cheap water shouldn’t be the fuel for population growth and speculative real estate development, and water planning needs to be more fully incorporated into land use planning, including in the upcoming state water plan. If there is a disconnect between the state water plan and land use, the plan is doomed to fail.

Read more about the latest push to divert more of the Colorado River: “Water has never come easy in the West, and when people start eying the last few drops of an already dying river, things can get tense in a hurry, even in an era of Colorado River Kumbaya …”

Morel madness

I also reported on the start of the wild mushroom foraging season in Colorado, which starts in the grassy cottonwood bosques along the Front Range, when tasty morels start to sprout in hidden clumps. Morel, along with several other fungi, are important players in wildfire ecology, helping to prepare the soil at a very mollecular level for new shrub, grass and tree growth.

Frack no more!

And in case you missed it the previous week, the Boulder Weekly also let me ramble on about beer, fracking and travel in the food section, as I tried to track down whether there is any real threat to Colorado brewers. Read the story here: “As a red-blooded American beer enthusiast with deep roots in beer culture, I got a little riled up when I read a press release a few months ago from a group of brewers concerned about the potential impacts of fracking to their water supplies …”

Deep sea dump

For Summit Voice I interviewed marine ecology professor Kerry Howell about her study of human garbage that’s piling up in some of the most remote ocean depths. Heineken beer cans, Uncle Ben’s rice packets and more, all washing off land and down into submarine canyons, where samples across wide swaths of sea bottom, from the Arctic to the Azores, showed as many as 10 pieces of garbage per acre. Rea the story here: “It’s not the best when your feeding apparatus is covered with plastic …”

Pay to play?

Nobody in Colorado covers recreation fees like Summit Voice. The controversial pay to play program is back in the news, as a California judge ruled that the Forest Service violating the law by charging a general public lands admission fee with a widespread adventure pass program. At stake is free access to trailhead parking on public lands across the country. Read: “The Forest Service is prohibited from charging a fee solely for parking. If a visitor does nothing other than park, the fee is solely for parking and is, therefore, plainly prohibited by the REA,” the court ruled, referencing previous court decisions …”

Mushrooms create mini-windstorms to spread spores

Releases of water vapor create convective movements

FRISCO — We’ve all heard of microclimates, where topography and other factors can affect weather on a very local level. But new research suggests that mushrooms take that concept to whole new level, creating their own mini-windstorms to help spread spores.

Biologists have long thought that the spores produced by a mushroom’s cap simply drop into the wind and blow away. But observers have noted that spores disperse even when the air is still. It took a detailed study by fluid dynamics researchers find the answer.

Using high-speed videography and mathematical modeling of spore dispersal in commercially grown oyster and Shiitake mushrooms, they found that the fungi created their wind by releasing water vapor. The vapor cools the air locally, and this creates convective cells that move the air around in the mushroom’s vicinity. Continue reading

Forest comes alive with fungi

FRISCO —It’s pretty hard to walk anywhere in local forests and fields without stumbling across a patch of mushrooms. Lingering monsoon rains and relatively warm temperatures have fostered an incredible diversity of fungi this year.In many years, we’ve had at least a couple of frosts by this time of year, which generally means the end of the season for all but the heartiest species. During a short walk near Officers Gulch Thursday I spotted more than 30 species in less than 15 minutes before losing count, and there are at least a half-dozen species growing in the landscaped areas around our Frisco townhome complex. Get out and enjoy it now, because it may well be several years before we have another season like this one. Continue reading

Whew!

Here’s how the day started in Summit County, with a little help from Instagram.

FRISCO — Labor Day weekend got off to a good, if somewhat soggy, start, with visitors from the Front Range and around the country thronging the high country for one last summer weekend, even as ski resorts started ramping up sales efforts for season passes. But the lingering monsoon has kept things pretty warm. The moist air acts like a blanket; so far we haven’t had those first few crisp nights that often do in late August, but nobody is complaining.

Sunday magazine: Mushroom mania in Colorado

From tasty meals to myco-remediation …

FRISCO — Fungi fanatics are calling it one of the best seasons in recent memory, as steady summer rains spurred a bumper crop of stinky squid, shaggy ink cap and purple slime mushrooms, not to mention delectables like porcini and chanterelles.

This past weekend, a handful of Colorado towns held festivals to celebrate mushrooms in all their diverse glory — if we’re all connected intellectually via the electronic web, then we’re probably also connected biologically, and fungi are one of the key threads that holds the web of life together.

In Telluride, amidst the good-natured fun of mushroom-themed parades and cook-fests, scientists discussed the latest research on myco-remediation. There’s promise that known — along with as-yet unstudied species — that fungi could help with a wide range of environmental and human health issues.

The mushroom festival maintained a lively social media feed on Twitter, sharing images like this:

In some situations, fungi could help clean up lead contamination, and Forest Service scientists are trying to improve restoration of dwindling whitebark pine forests with fungal applications.

In Scandinavia, forest researchers have discovered that fungi play a greater role in the carbon cycle than previously understood, and there are also concerns that a warmer and wetter future world could spur the growth of forest-killing fungi. Continue reading

Berries-n-shrooms!

Wild strawberry Colorado

Wild strawberries are a special forest (and meadow) treat in Colorado.

FRISCO — Even a short walk in the woods can be rewarding these days, what with wild (and delicious) edible mushrooms popping up all over, along with a veritable feast of berries, which always do much better in wet years, especially when the rains are followed by some warm and sunny days. All this on a day that also brought the first snow to the Colorado high country, although we probably shouldn’t even think of it as the first snow, since it’s only been a few short weeks since the last time frozen white stuff fell from the sky. But for some reason, in August, it does feel like the first snow of the new season, while a July dusting (also not unheard of) seems to belong with the past winter. In any case, get out and enjoy summer’s bounty now! Continue reading
