HISTORICAL versus CONTEMPORARY WILDFIRES

/0 Comments/in , , , , , , /by

Wildfires in the mountain west have become less frequent but more intense.

Recently, the Denver Gazette published a short article on current research comparing historical versus contemporary wildfires in the America Southwest, with (to this reader) some rather surprising results.

The areas investigated in this study were primarily dry conifer forests dominated by Ponderosa pine and Douglas fir, very similar to our own forests in the Jeffco Front Range. Prior to 1880, wildfires used to sweep through these forests every 10 to 12 years. These were almost entirely low-to-moderate intensity fires that cleared out undergrowth and forest duff, burning off the lower limbs of the trees, but not devastating enough to kill the trees themselves. Typically, these low-intensity burns involved smaller areas, 5 to 250 acres. Despite the small size of these wildfires, the frequency and style of these fires were able to maintain forest health, even during prolonged periods of drought, when fires were started by lightning strikes and/or Indigenous forest stewardship events.

The Invasives – Poison Hemlock & Cow Parsley

/0 Comments/in , , , , /by

Poison Hemlock thumbnailIt’s time for a change of pace. Today we’re going to talk about two invasive plants that look so similar but which have drastically different consequences. Both can be found in our Open Space parks.

Poison Hemlock v. Cow Parsley — can you tell the difference?  Here’s an article written for Foothills Living Magazine; we’ve been given permission to post as a public service.

Why be concerned about this, or any other invasive plant? They’re called invasives because they’ve moved into an ecosystem within which they did not evolve, usually with help from human activity. When this happens, when an invasive finds a new environment within which it can thrive, it’s usually without the lifestyle controls with which it evolved. Without these restraints, the invasive not only thrives, it takes over and overwhelms indigenous plants, sometimes to extinction. The plant-eating critters that evolved with the indigenous plants may not be able to tolerate the invasives, and they, too, fail to thrive. The carnivores who feed on the plant-eaters begin to fail…and so it goes, like a stack of dominoes. That’s why invasives — the plants — need to be controlled and in the worst cases, eliminated.

So when you’re trekking in the Jeffco Open Space Parks, keep your eyes peeled for these lovely but, in some cases, deadly invasives — and don’t touch!

ME, MY DOG & THE GREAT OUTDOORS

/0 Comments/in , , , , /by

This is a repost of the article written in April 2021 by D. Jean Tate. Riley is no longer with us, but Jean and Leia, her new trekking companion, continue to visit the Parks. The information and lessons learned are as important today as they were in 2021. We hope you appreciate the reminder and enjoy the read.

Jean Tate and Riley at White Ranch OS Park

Sharing the outdoors with your dog—it’s one of the most enjoyable things I know!  For that reason—and because our open lands and trails are used by wildlife plus an ever-increasing number of people for a variety of activities, and also because of dogs’ natural inclinations—there are rules to be followed when you and your dog are outdoors, outside the bounds of your private property.  Those rules vary by location based on political boundaries, land ownership, and land management.

Your PLAN Jeffco Board members (left to right) Cathi Schramm, Michelle Poolet, and Courtney App, get ready to head out into Crown Hill Park to plant trees and shrubs.

What were you doing on the Saturday before Earth Day, 2024?  Three of your PLAN Jeffco Board members joined 124 other Jeffco Open Space volunteers to plant more than 350 (some say as many as 600?) native trees, shrubs and forbs (grass plugs) at Crown Hill Open Space Park, along with multiple patches of native wildflowers.

The day was dark and gloomy, but the planting crew trudged on through the snow and mud…

Despite the cold and snow, 127 conservation enthusiasts weathered the chilly temperatures, including 50  Columbine High School students.  Traipsing through the snow and mud, lead by JCOS Natural Resource and Trails staffers, we got the job done before the snowfall resumed in the early afternoon.

One more Rocky Mountain Glow maple tree planted — hurray!

Initial success was measured by the feeling of accomplishment as a tree – in this case, a Rocky Mountain Glow maple – went into the ground. With luck and average annual rainfall (the trees on the east end of the park will not get any supplimental water), this maple will grow 20 to 30 feet tall, and will bear reddish-gold leaves in the fall. The chokecherry, wax current, rabbit brush and potentilla will grace the park with their flowers and fruit, while providing food and shelter for the smaller native inhabitants of the park.

The morning’s wet and cold and muddy activities wound up with a hot lunch buffet, catered by Illegal Pete’s and served by staffers from the JCOS Communications Team. The food was delicious – roasted meats, rice and beans, and Pete’s famous fajita and primavera veggies were top of the line, with plenty to go around.  To top off the meal, the chocolate chip cookies were baked to the chewy stage, so good that they begged you to have another one.

It might be safe to say that, despite the inclement conditions, everyone at the Earth Day event had a good time.

Our thanks to JCOS and the Natural Resource, Trails and Communications teams for organizing and executing this 2024 Earth Day activity, and for upholding the meaning and intent of Earth Day.

From National Geographic Education encyclopedia: “Earth Day is an annual celebration that honors the achievements of the environmental movement and raises awareness of the need to protect Earth’s natural resources for future generations. Earth Day is celebrated on April 22 in the United States and on either April 22 or the day the spring equinox occurs throughout the rest of the world.”

Miss Mountain Manners says: “This coming summer, when you’re strolling around Crown Hill Open Space park, look for native wildflowers on the north side, along 32nd Avenue, across from Wheat Ridge High School — but don’t pick the flowers! In the fall, as you walk the trails on the southeast side of the park, please stop and admire the red-gold leaves of the young maple trees and the brushy golden flowers of the rabbitbrush. Be proud of being a part of Jeffco Open Space.”

Empty pillar where interpretive sign once stood.By Vicky Gits and Bette Seeland, Nov 26, 2023

Early this year Jefferson County Open Space quietly removed without replacing an interpretive sign that had stood for about 20 years as a tribute to the visionaries whose genius and hard work launched PLAN Jeffco and created the Open Space Park system.

Now that the sign is gone, it is probably gone for good, according to Matt Robbins of the Open Space department.  Positioned in Elk Meadow Open Space in Evergreen, the sign was removed because it had fallen into disrepair after weathering outdoors for so long.

Evergreen resident Joe Mackey brought the missing sign to the attention of the Open Space Advisory Commission in October at a regular meeting. A former member of OSAC in the ‘70s, Mackey thinks the sign should be preserved. Read more

One of the many components of Jeffco Open Space is the Trails Partnership Program. The TPP is a grant program that provides supplemental funding to assist partners in implementing their priority trail projects within Jefferson County. These grants are awarded on an annual basis, provided that funding is available.

At the November 2nd (2023) Open Space Advisory Committee meeting, Open Space staff presented to OSAC an overview of the TPP applications and proposed funding amounts for 2024. Resolution #23-12, which includes the following projects, was approved that evening: Read more

CROWN HILL OPEN SPACE PARK – A BRIEF HISTORY

/0 Comments/in , , , , , /by

What we know today as Crown Hill Open Space Park wasn’t always a public venue. One year before the end of the American Civil War, in 1864, a young man named Henry Lee sojourned west from Iowa to join his brother, William, who had a farm east of Golden, on the south side of Clear Creek.

The land was rich, fertile enough to support wheat fields (Wheat Ridge), fruit orchards (Fruitdale) and further to the north, the farms that would one day become the city of Arvada.

While William worked the farm, Henry traveled on the narrow gauge railroad up Clear Creek Canyon to the mining camps in Gilpin, Clear Creek, and Park counties, selling vegetables to the residents.

In less than 10 years from the time of his arrival, Henry had met and married Jennie Paul, another Iowa ex-pat, and settled down to a married and family life on land that Henry was now farming.  Read more

Alderfer/Three Sisters Forest Health 2023-2024

/2 Comments/in , , , /by

Alderfer3Sisters Open Space ParkIf you’ve recently been out to Alderfer/Three Sisters Park recently, you’ll notice that there’s a lot of forestry activity happening, especially in the eastern one-third of the park.

Managing and maintaining forest health is incredibly important to the safety of everyone and everything, and so, after 100+ years of the forest overgrowth, JCOS is able to start work on this park.

Starting in August 2023, the JCOS Forest Management Team will remove seedlings, saplings, and even some larger trees – mostly Ponderosa pine and Douglas fir – so that the density of the forest will be reduced. Eventually some 240 acres throughout the entire park will be mitigated. This will result in a healthier ecosystem that will be far more resilient to wildfire than what is currently in place. Read more
