Ferruginous Hawks struggling in Eastern Utah

Any of you who are birders might find this story in the Salt Lake Tribune interesting. Sounds like the Ferruginous hawk population living in the Uinta Basin near Vernal is struggling. There's been extensive development of the natural gas resources there and the long term disturbance has had a detrimental effect on the nesting activities of these raptors. Here's the link to the story. What's encouraging about the story is someone (the group Utah Wildlife in Need) is actually doing something positive for the birds.

Zion National Park's Horse Fire Update

In the previous post we talked about the lodgepole pines trees and how wildfire plays a role in their life cycle. Lodgepoles are a "pioneer" species, meaning they are the first tree to re-establish after a forest fire. We also discussed how the government's policy of forest suppression over the past 50-100 years has resulted in a forest make-up that is possibly more suseptible to pest infestation. Fire management has changed radically in recent years, and the Horse Fire in Zion National Park is a perfect example. I started following the progression of the Horse Fire two weeks ago on July 9th. Rather than aggressively put out the fire, the fire fighters on the Horse Fire have been letting the fire burn, in a controled fashion. Here's the goal, according to the National Park Service Website update:

"The fire is burning in a fire-adapted ecosystem and is achieving the resource benefits it is being managed for. Most of the area has shown a light understory burn, with little torching of larger trees. This will reduce the amount of dead and down fuel and provide an opportunity to regenaration of native plants. The reduction of fuels will also lower the risk of wildfire to adjacent private lands from future wildfires."

Although the fire has closed a section of the West Rim Trail for a couple weeks, its in the remote, northern portion of the park. Aside from some smoke settling Zion Canyon at night, there little adverse effects from the fire. Its cool to see a new approach being implemented!

Utah Field Guide - Lodgepole Pines and how the tiny pine bark beetle is transforming the forests of the American West

Why are the forests dying? I get this question almost every day on my raft when I'm working as a river guide. I guide on the Salmon River near Stanley, Idaho, in the Sawtooth National Recreation Area, one of the prettiest natural settings in the United States. The surroundings are gorgeous, but there's no denying it, the forests around the river are dying. Everywhere you look, you see stands of red (starting to die) and brown (dead) trees clustered together in sad, lifeless clumps.


The die-off isn't limited to Idaho. You'll see it anywhere in the American West where lodgepole pines grow. The entire Rocky Mountain Region is suffering from the blight. Including Utah. The problem is particularly apparent in the Uinta Mountains along the Mirror Lake Highway, where the trees are withering by the hundreds in almost every campground. Who's the killer? And why isn't anyone doing anything about it?

The lodgepole pine forest is being killed by the Rocky Mountain pine bark beetle (Dendroctonus ponderosae). That's right, tiny (1/2 centimeter long) beetles who burrow into the bark of the tree and kill the host from the inside out. In the Western United States and Canada bark beetles have killed 36,000 square miles of forest. Depending on the area, beetles have infested as much as 40% of the lodgepole trees in the forests, and may kill up to 80-90% of the mature trees before they're done. With 90% of the trees dead, the forests will look almost entire devoid of green, living trees.

Isn't there something we can do to stop the beetles? We'll dive into that later. But first lets get a little more familiar with lodgepole pines, how to recognize them, where to find them and why they're such an important part of Utah's mountain ecosystems.

Characteristics: Lodgepole pine trees (pinus contorta) are distinctly recognizable by their rail straight trunks and high thin crowns. Their trunks are popular for traditional fences on western
ranches and are often used to build cabins because they are so consistently straight. Historically in Utah, lodgepoles were used to support mine shafts and for railroad ties. The needles of a lodgepole pines are short (relative to ponderosa pines), about 2 inches long and grow coupled together with other needles. The needles are twisted or contorted, giving the tree its scientific name pinus contorta. The bark is thin and scaly, and ranges in color from orange-brown to gray.





Where to find lodgepole pines: Lodgepole pines usually grow above 6,000 feet in elevation in mountainous terrain. In Utah lodgepoles pines can be found in the mountains in the northern half of the state. The Uinta Mountains have the largest and most widespread distribution of lodgepole. Stands of these trees will often be associated with a natural disturbance such as fire, or in areas where the forest has been cleared by people. Their cones need extreme heat to release their seeds. In nature this heat is only generated by wildfire, so fire is necessary part of the lifecycle of lodgepole pines. Their niche as the first species to establish after forest fires makes a "pioneer species" playing an important role in forest succession.

Now that we have a feel for what lodgepole pines look like and where they live, lets explore what's happening with the forest and the pine bark beetle.

Pine bark beetle infestation: Pine bark beetles have always been present in the Rocky Mountain environment. The populations ocilate on a boom and bust cycle, much like other insects. The most recent major infestation occurred in 1983. Beetles attack the tree by tunneling into the bark where they lay their eggs. Young larvae mature inside the tree before leaving it to find a new host for the next generation.

What makes this infestation different from previous ones is how large and widespread it is. Biologists believe there are several factors contributing to the scale of this infestation. One factor is the current make-up of the forest. Pine bark beetles only infest mature lodgepole pines. We've already mentioned that lodgepole forests tend to develop in places where there's been some disturbance, whether that be a wildfire, or a man-made, such as logging. The suppression of forest fires may be playing a role in this current cycle. Because there have been less frequent fire events overall in the American West in the last 50-100 years, there are more mature trees in the forest for the bark beetles to attack. This is a result of larger trees not being burned in fires, but also a lack of fires releasing seeds from cones. So, there is effectively more food and habitat for these beetles than during previous cycles. Another contributing factor may be a prolonged and widespread drought. The trees natural defense against the beetle is sap. Trees bleed thick, viscus sap in an effort to flush the beetles out of the their bark and prevent them tunneling into the tree. Drought conditions prevent the trees from producing as much sap, thereby reducing their natural defense system against the beetles. Warmer weather has also aided the beetles in their expansion. Week-long periods of extreme cold weather can kill entire generations of pine beetles, but a long run of warmer winters has allowed the pest to survive.

What can be done about this outbreak? Unfortunately, not much. Typically outbreaks last for one to three decades. A long period of bitter cold temperatures could cause the outbreak to collapse. But much more likely, it'll be matter a the beetles running out of food - meaning most of the trees will be dead.

Free Weekend in Utah's National Park!

Have you heard about the National Parks System's Fee Free Weekends? The National Park Service is waving the ENTRANCE FEE to the National Parks in over 100 different parks this weekend (July 18th and 19th) and again for the weekend of August 15th and 16th. Here's the link to the NPS site. In Utah the parks that are included are some of the state's (and the country's) best. Here's the list (with photos for inspiration!):

Arches National Park








Bryce Canyon National Park








Canyonlands National Park








Capitol Reef National Park












Cedar Breaks National Monument








Dinosaur National Monument








Hovenweep National Monument












Zion National Park








Golden Spike National Historic Site

Natural Bridges National Monument

Granted a lot of the smaller parks don't charge a entrance fee anyway, but Arches, Bryce, and Zion all normally charge a hefty fee, so this is really awesome deal. With five national parks in southern Utah, you could save a Benjamin over the weekend. Note: only the entrance fee is being waived, you'll still have to pay for camping, tours and concessions. If you're going to go camping in the one of the parks check out our guidebook Moon Utah Camping for a complete guide to every campground in Utah's national parks and the state as a whole.

Wildfire closes the West Rim Trail in Zion National Park

A wildfire, named the Horse Fire, is currently burning in the high country of Zion National Park near the West Rim Trail. The fire is approximately 1.5 miles southeast of Lava Point. The fire was started by a lightning strike on the 4th of July. The National Park Service has closed the trail from Lava Point to Potato Hollow. The small fire has burned 20 acres and is being managed by a multi-agency team including the park service, BLM and Utah state officials.

Here's the view down into Zion Canyon from Lava Point, where the fire is burning.


If you've got a trip planned to Zion, don't panic. This is a small fire in the northern part of the park. Unless you're planning on backpacking the entire length of the remote West Rim Trail, the fire probably won't have a significant impact on your visit. Zion Canyon (the main attraction in the park) is still open and as accessible as ever. The park service expects some smoke may settle into Zion Canyon at night, but doesn't predict it will be a major concern. If you'd like read the official park service report on the fire you can see it here.

If you're heading to Zion, pick up a copy of our camping guide, Moon Utah Camping. The book has all the info you'll need for camping in the park as well as recommended hikes in Zion Canyon.
