What's the HYPE about anyways?

I’m here to tell you all you need to know about HYPE, why it’s important, and why you should care. So first off, I guess I should tell you what HYPE even means anyways.

HYPE is most commonly the fancy abbreviation for Hypericum perforatum. This specifically is the Common St John’s Wort species. Yeah, you’ve probably heard of St. John’s Wort before and you probably also know that it’s a noxious weed. Hah! You didn’t know the HYPE was all about invasive weeds did you?! Well hold your horses before you leave, because HYPE isn’t just that - did you know that there’s actually several species of Hypericum and they’re NOT invasive. You heard me right folks! There’s native HYPE out there - and that’s what I want you to get HYPEed about. Now are ya with me?!

Common St Johns Wort (the bad HYPE)

Western St Johns Wort (the native HYPE)

First though, let’s get all the nitty-gritty of the noxious invasive out of the way. Let me hit you with some fast facts:

  1. It was listed as a noxious weed in 1988.

  2. Can be toxic to horses and livestock.

  3. Spreads on disturbed, open, and dry areas.

  4. Klamath beetles work as a biocontrol and feed on these plants. GBCA actually gets to release some of these each year!

  5. One plant can produce over 10,000 seeds in a SINGLE year!

Okay, but here’s the cool thing: there’s a species of HYPE around here that’s native - what we call Western St. John’s Wort (Hypericum scouleri). And we’ve been seeing a lot of it this year! Now let’s hear about this HYPE:

  1. Tends to grow in more wet and higher elevations.

  2. Is shorter that Common HYPE.

  3. Only present in the western states, whereas H. perforatum has a wide range.

  4. Generally just cuter, and grows in smaller patches.

Lucky for us, these plants tend to grow in different environments which means WE don’t have to get them confused, and the bad stuff can still be treated and monitored. So there it is, now you know a little more about the HYPE.

For any further questions or ways to get involved in weed control or monitoring, please reach out, we’d love to hear from you!

Fire Resistance: Among the Trees

The forests are pretty awesome in ways that they are able to protect themselves whether it be against beetles, fungi, fire, or even humans. This week, we’re highlighting three of our resident firefighters in the forest. These guys play a big part in fire behavior, fire ecology, and post-fire revegetation. Next time your out and run across one of these friends make sure you thank them (yes, be a tree-hugger!) for everything they do in the forest.

Western Larch

Larix occidentalis

Western larch is the most fire resistant tree we have around here. Its bark helps to insulate it against fire and can be up to 6” thick at the base! By self-pruning, or dropping their lower branches, they create less of a risk of the fire climbing into the crown. And also, their needles are not very flammable since they are replaced each year. Western larch regenerates the best in open areas with lots of light, so they are one of the first colonizers following a fire.

Ponderosa pine

Pinus ponderosa

This tree is special as even its young saplings are considered highly fire resistant. Their long needles help to shield their buds from heat and flames. Ponderosa pine does not have much lichen growth and typically grows in more open habitats. Their roots dig deep into the ground. Ponderosa pine actually has the best regeneration rate when on mineral soil and ash.

Douglas fir

Pseudotsuga menziesii

Although when mature they are considered very fire resistant, young Doug firs do not have the ability to stand up against fires, causing them to fall third on our list. Douglas fir has thick bark that helps the tree withstand medium intensity fires. They grow very slow which makes them a very strong tree in many aspects, however, their roots don’t grow as deep, they are known to have some beetle problems, and mistletoe growing in their branches gives more room for the fire to spread.

2023 Stewardship Trip recap

Kid Lake Meadow Restoration
Restoration Director (Chris) and Volunteer Coordinator (Kalyn) were joined by volunteers to aid in restoration efforts in Kid Lake Meadows. The group pulled over 50lbs of the noxious weed, St. John’s Wort, established 2 new Standard Impact Monitoring Protocol (SIMP) plots, and surveyed the newly established SIMP plots.

These SIMP plots will be surveyed every year to monitor for:

  1. Noxious weed populations (and the effectiveness of treatment)

  2. Biocontrol populations that keep those weeds in check

Monitoring biological control agents is an essential component of a successful biological control program. Capturing this data helps us accurately document the impact of this weed management practice. SIMP is a nationally recognized platform that has been adopted to capture data and perform analysis on biocontrol release sites. The data captured is used to document vegetation cover, weed density, and biological control agent abundance. This type of monitoring allows us to track trends in both of these populations, which will help us to determine how effective different treatments are over time.

Heart Lake Trail Improvement

Stewardship Coordinator, Joelle, was joined by volunteers to assist the USFS trail crew with trail improvements on the well used trail 171! A bulk of the work was centered around re-directing a portion of the trail in order to mitigate tree root damage. Volunteers worked hard to clear the new section of trail.

Species Highlight: Western Red Cedar (thuja plicata)

Overview

The Western red cedar (Thuja plicata) is a special tree that we are lucky to have in the Great Burn area. There are many groves to be found on and off the trails - some old growth, and some new that are now thriving. Although fairly common, this tree should not be taken for granted as it has held great cultural and ecosystem importance throughout time.

Fast Facts

  1. The Western red cedar is not a true cedar, it’s actually part of the cypress family.

  2. Most commonly in damp or wet forest.

  3. This is a coastal disjunct species found in the Great Burn mission area.

  4. Can live over 1,000 years.

  5. Can grow between 100-200 feet tall.

  6. Fallen branches can actually develop roots and form a new tree.

  7. Second growth wood is not as resist to decay as old growth trees.

  8. The reason why you may sneeze around cedar is because it contains plicatic acid which in itself provokes asthma and allergies.

  9. Bark is traditionally used for baskets, nets, and rope.

  10. Cedar is special due to its durability and its relative light weight.

  11. Has rich cultural value among many tribes, many times being referenced as the “Tree of Life.”

  12. It seems nearly impossible to walk by one without hugging it.

Flora in the Field: All about Heath (Ericaceae)

The members of the Ericaceae family are grouped together based on similar reproductive structures, appearance, and preferred growing conditions. Many of these plants are found in well-drained soils in the dark cover of a canopy or in the high elevations of the mountains.

Some that we have featured are truly special in that they are saprophytes. This means that the plant lives on dead, organic decaying matter. Because of this, saprophytes don’t need green leaves as they don’t conduct photosynthesis.

Check out some of the awesome heath plants found in this region!

Flora in the Field: Weitas Creek #20

Weitas Creek #20 is a main trail in the North Fork District of the Nez Perce-Clearwater National Forest. The north end of the trail is found where Weitas Creek dumps into the North Fork of the Clearwater on the FS250 road. The trailhead is in Weitas Campground. The south end of the trail begins at 12 Mile Saddle on the Lolo Motorway. Being just under 30 miles, this trail hosts many adventures and many flowers.

Spring Flora: Why Are They Yellow?

The spring weather is finally starting to roll around here in the Missoula valley. As you’re out and recreating, you’ll start to notice that the flowers are bursting at the seams ready to show their colors for you this season!

Have you ever wondered why most of the early bloomers are yellow or white? Well, you’re not crazy… this actually is the case. These colors help out the pollinators of these plants. Most times, flies are one of the first pollinators of the season, and flies have pretty bad vision - “color blind” as one may call them. The yellows and whites help to reflect the greatest amount of light and attract any pollinator that may be around to help out these plants. They’re not picky, they’ll take any help they can get in this early season.

Wondering what you’re encountering on the trails? Here’s a few that we’ve found on our recent hikes:

Idaho goldthread (Coptis occidentalis)

This is a very early flowering plant, the flowers are actually rarely seen since sometimes it actually blooms when the area is still covered in snow. An endemic species to the Northern Idaho and Western Montana area which is pretty awesome! A very delicate little plant, found in coniferous forests, so be sure to check before you step!


 
 

Glacier lily (Erythronium grandiflorum)

Such an exciting sight at the beginning of the season, especially when you run across an open side slope covered in them. These guys are super important forage for bears as they begin to emerge for the season. Their bulbs are also edible to us, but please be mindful of the area if you forage this season and always double check your ID.

 
 

Yellowbell (Fritillaria pudica)

Also known as a snowdrop, these flowers look similar to the Glacier lily, except they have rounded petals and don’t curl back toward the sky. Found on open slopes and sometimes near streambanks. Another very important food source for early-season bears and ground squirrels.

 
 

Sagebrush buttercup (Ranunculus glaberrimus)

Like buttery popcorn, this flower is always a welcome sight, even on the hillsides surrounding Missoula. Often seen growing in patches and close to the ground, it can pepper the hillsides as early as March (although we’re just starting to see it around here this year).

 
 

Smooth prairie star (Lithophragma glabrum)

Found on a tall, slender, leafless stem, these small white flowers look like a starburst - especially when first opening. Flowers are mostly white, and sometimes pale pink as the season progresses. Keep an eye out for these in the meadows and on sideslopes and the snow recedes.

Spring flowers help to give us so much hope for the warmer season ahead! These plants serve as important food sources for many different animals as the days begin to lengthen. Keep an eye out for these and any others you find as the snow melts and the season progresses. Let us know if you find anything awesome out there, and as always please share pictures and stories!

Flora from the Field: Mallard Larkins

Another very exciting hitch with many different types of flowers seen along the way. With all of the sun, the flowers seemed even more vibrant than before. Right away, on the first day, Leslie (top middle) was proud to be pulling up houndstongue (Cynoglossum officinale), found along Black Mountain #396. This is an invasive plant in the area that is toxic to livestock. The most abundant flower by far was seen on #396 trail, lining the hike. This starflower (Trientalis borealis; top right) is rather short, but very showy. The Down River #297 trail was just beginning to enjoy the blooms of the Clarkia (Clarkia pulchella; bottom left). This is a native to the area, and will often cover hillsides in its vibrant pink color. At Goat Ridge, on the Smith Ridge #240 trail, spreading phlox (Phlox diffusa) was covering the ridge in all shades of purple and white (top left). And finally, the most exciting sighting of the hitch was the phantom orchid (Cephalanthera austiniae; bottom right), originally spotted on the #396 trail, but an individual was also later found on #297. This orchid is completely white and native to the area, although only growing in specific areas.

There were many fun sightings on the trails during this hitch, even despite the rain. This Garden tiger moth caterpillar (Arctia caja; bottom middle) was found near camp on Wednesday. There were many of these blister beetles (Meloe spp.; top middle) found along the trail #95. Common flowers included Western spring beauties (Claytonia lanceolata; top left), Foamflower (Tiarella Cordifolia; middle left), Bunchberries (Cornus canadensis; middle right), and Black elderberry (Sambucus nigra; bottom right). There were several Pacific yew trees (Taxus brevifolia; top right) along the Isabella Creek #95 trail before the #96 junction. A rare for the area sighting was the deer fern (Blechnum spicant; bottom left) which was found on the #96 trail.
