Fire: A Prescription for the Forest

Low-intesity flames travel across the forest floor during a carefully planned prescribed fire at the Museum.
Low-intensity flames travel across the forest floor during a carefully planned prescribed burn at the Museum.

This spring, one cloudy May day, we watched flames creep across the floor of part of the Museum’s ponderosa pine forest. For a long time, we had been carefully planning for this prescribed burn of a portion of our acreage. The fire, though low intensity, still left a somewhat dramatic sight for our visitors the next day.

While some understood what we’d done and why, others came with questions. Some were curious, a few concerned. Why would we set the beautiful forest on fire, leaving the ground blackened and stumps smoldering? In short, for the health of the forest and the safety of the Museum and our community. It’s called a prescribed burn for this very reason.

Flames belong in the forest, an ecosystem that has evolved to withstand, and benefit from, the heat. Historically, low-intensity wildfires would burn through a ponderosa forest every five to 20 years. This would help to clear out shrubs, saplings and some of the pine needles and other litter lying beneath the trees. Larger trees would remain intact, their thick bark serving as a shield. The heat would open ponderosa cones and enable them to release seeds, continuing the natural cycle.

For centuries, people have suppressed wildfires in the West. Fuels have built up on the forest floor, and shrubs and trees have grown into unnaturally thick stands, depriving certain wildlife and plants of the habitat they need to thrive. When lightning or human actions start fires, as they inevitably do, they therefore often burn unnaturally hot and can inflict substantial ecological damage. A high-intensity wildfire would also threaten the Museum, our artifacts and the wildlife in our care. The damage that an out-of-control wildfire could cause is eye-watering — much more so than the smoke from our prescribed burn.

We are grateful to the U.S. Forest Service for partnering with us to plan and implement our burn. The process began with removing shrubs and small trees, reducing the fuels that had built up. We checked for ground-nesting birds before we mowed.

Some visitors have wondered aloud whether we could have just mowed the forest and left it at that. A low-intensity burn offers some unique effects, however. It increases the availability of nutrients, encouraging native plants to thrive. Fires can also create snags, which provide food and habitat for woodpeckers, bats and others. Only a portion of the property was mowed and burned, increasing the diversity of habitat types for the benefit of a wide range of species.

Ground fuels are measured after the Museum's prescribed burn to calculate what percentage was removed by the fire.
Measurement of ground fuels help U.S. Forest Service managers calculate the percentage of fuels removed by the Museum’s prescribed burn.

Over the years, we have been seeing fewer raptors and ground-nesting birds on the property. Both trends might be due to the density of vegetation and forest debris. More ground squirrels and other small mammals are able to stay safe under thick cover. Ground-nesters, such as quail, then face pressure from ground squirrels, for whom bird eggs make a tasty meal.

The burn has created a more diverse habitat, with some bitterbrush remaining, but also more open areas. As a result, hawks should now enjoy improved hunting success, which in turn will help to keep the rodent population in check.

Forest managers always weigh potential benefits against the actual and potential costs of a prescribed burn. In this case, the benefits dwarfed any negatives and we were excited to return fire to the forest. The result should be a revitalized and resilient ecosystem that supports an abundance of native plants and wildlife.

The new interpretive signs along the Museum’s Fire in the Forest Trail offer visitors a chance to understand the important role of fire in ponderosa pine habitats.
This burn also provided a fantastic opportunity to connect our community to the importance of forest restoration. Together with the U.S Forest Service, we took photos before and after the burn in specific locations, and will continue to do so for years to come. In doing so, we will capture the restoration process and communicate the important role of fire to our visitors. We also took measurements of the fuels on the ground, so that we can calculate the percentage of fuels that the burn successfully removed.

In addition, we have renovated our fire trail, Fire in the Forest, with additional signs along the loop to further explain the role of fire in ponderosa pine ecosystems. Have a look next time you visit the Museum! And watch, too, for the incredible regeneration that will happen in our forest over the next few months and years. We are already seeing small signs of new life.

Spring Activities for Kids

As the sun’s rays shine between the trees, glinting off the frost covering the bare aspen branches outside my window, I can feel the promise of spring, even as winter weather lingers. I know that soon buds on aspen branches will burst with fresh spring leaves and winter will give way to a new season! The arrival of spring is one of my very favorite times of the year. It’s a great time to get outside and explore. Longer days, warmer temperatures, new leaves and blossoms, and the return of migrating birds await you.

There are so many ways to celebrate spring, no matter your age, but these are some of my favorites!

1. Go on a hike and look for signs of animals!
In the spring, animals such squirrels and rodents are emerging from hibernation or torpor (periods of long slumber, but not true hibernation). You’ll see signs of their activity such as chewed pine cones and nibbled plant shoots.
Make a simple chart to focus your observations. Sketch what you see!
– Scat (animal poop)
– Tracks (footprints)
– Forage (chewed pinecones, nibbled branches, etc.)
– Homes (nests, dens, etc.)

Come stroll the Museum’s many nature trails and look for signs of animals such as the golden-mantled ground squirrels and chipmunks, which are very active this time of year. Check the feeders in the wildlife viewing area for spring activity. Talk with a wildlife expert at the Museum if you have any questions about birds and mammals you’ve seen during your visit.

After watching the busy songbirds at the Museum’s feeders, get an up-close and personal view of raptors during our “Sky Hunters” program, offered for a limited run each year during spring break (March 24-31, 2018). Watch as powerful aerial predators take flight overhead in this intimate, free-flight demonstration showcasing each bird’s agility and grace. Date, time and price information can be found on our website calendar.

Families with young children will also enjoy exploring our “Who’s Home?” interactive exhibit. Watch as your little ones get creative, imagining they are snakes in the rimrock, just emerging from hibernation!

2. Start sunflower sprouts!
Sprouting seeds indoors before you plant outside helps the plant develop in a controlled environment. Or, rather than planting outside, have you ever eaten fresh microgreen sprouts? They are extremely nutritious, and, when grown in your own kitchen, very local!

By planting sunflower seeds inside, you can choose to transplant some outside where they will grow into tall sunflowers come summer, and save some for a delightful, edible treat.

Black oil sunflower seeds are my favorite. You can find quality seeds at a garden supply store, or by searching online.

1. Purchase quality seed. I use black oil sunflower seeds. Though other types will work, these are the least expensive.
2. Soak your seeds in warm water for 12 hours in a covered container. I recommend about two cups.
3. Drain and rinse.
4. Soak the seeds again in warm water for another 8-12 hours. (Repeat steps 3 and 4 until the seeds start to sprout.)
5. Once the seeds have begun to sprout, fill a clean, plastic nursery tray with moistened seed-starting potting mix nearly to the top.
6. Sow the seeds thickly across the entire tray then cover
it with another inverted nursery tray to block out the light. There is no need to cover the germinating seeds with more potting soil. Be sure there are some small holes in the top tray to allow for ventilation.
7. Water the tray from the bottom once or twice per day by setting the tray in a bigger tray of water for a few minutes.
8. As the shoots grow, they’ll push up the top tray (usually within a few days). At this point, remove the top tray to expose the growing seedlings to light.
10. Move the tray in front of a bright, sunny window.
11. Continue to regularly water by spraying shoots and soil with a spray bottle several times a day.
12. Harvest the sunflower shoots that you want to eat when they reach 4 inches high by cutting them off at soil level with sharp, clean scissors. Transplant the rest of the shoots outside!
13. Store unwashed sunflower microgreens in a sealed plastic bag in the fridge for up to five days. Wash them as you need them by running the shoots under cold water. They are delicious on sandwiches and salads!

By planting seeds indoors, kids get to witness every stage of the sprouting process, and then taste the results of their efforts and watch as their sunflowers grow and mature in the yard or garden.

Did you know?? At the Miller Ranch, the Millers are also getting ready to start a garden for the summer. Come ask the Millers about what they are doing to prepare their garden.
Spring is a prime time for sprouting in the great outdoors, too! Look for bud bursts and other signs of spring on the High Desert Natural History Walk at the Museum, offered daily.

3. Make a Bird Feeder
More than half of Central Oregon’s birds depart for the winter, leaving about 175 species that are hearty enough to survive the cold temperatures, snow, and scarce food. But come spring, migrant birds are returning and need to replenish after a long journey! Create this ponderosa pinecone bird feeder, and survey the local birds that come visit! Consider placing the feeder away from windows to mitigate collisions. Take it one step further and apply window stickers so birds don’t mistakenly fly into the glass!

You will need:
– Large ponderosa pine cones (found on the ground on an outside adventure!)
– Peanut butter (shortening for people with nut allergies)
– Birdseed
– String
– Butter knife
– A shallow dish
– And, of course, a place to hang your bird feeder! (a tree or bird feeder hanger work nicely)

1. Shake or lightly brush the pinecone to remove any dirt or debris. Trim off any loose scales that may break off as you create your feeder.
2. Tie string securely around the cone. Create a loop to easily hang your feeder from a tree branch.
3. Use the knife to coat the cone with a layer of peanut butter, pressing some between the rows of scales, filling in larger gaps. If the peanut butter is too thick to spread well, it can be warmed up slightly in the microwave to make it easier.
4. Once the cone is completely coated with peanut butter, roll it in the birdseed in a shallow dish, pressing lightly to keep the seed adhered to the cone. Work the seed in between the rows of scales.
5. Feeders can be hung immediately, or can be frozen for several weeks. The feeders do not need to be thawed before hanging.
6. Hang your feeder and carefully watch for visiting birds!
For bonus points, record the species you observe on eBird (www.ebird.org) – a partnership of the Cornell Lab of Ornithology and the Audubon Society. There, you can see what types of birds other people have seen in your area, and share your sightings with others.

Learning about birds in your own backyard is an excellent extension of learning to complement your Museum visit. What do the birds in your backyard have in common with birds at the Museum? How are they different?

I hope you can use these activities to embrace the changing seasons! Spring is a blend of showers and sunshine, but whether sun or rain (or even snow), there’s plenty to explore to stay busy! When you’re warming up (or drying out) back indoors, continue your celebration of spring with these books:

6 Ways to Keep Pets Safe in Summer

Here at the High Desert Museum, we’re taking steps to keep the wildlife in our care healthy and safe during this summer’s high temperatures, like providing fruit pops to the porcupines and spritzing the raptors with water. The otters? They’re content swimming and sunbathing. Caring for them in this extreme heat made us think of you and your beloved pets. We thought we’d share some simple things you can do to keep your pets safe at home and as you travel this summer.

1. Offer plenty of cool, fresh drinking water to keep your pet hydrated.

2. Dogs transpire through their foot pads, so offering cool water for them to stand in is an excellent and safe method to cool them off. During backyard play, sprinklers and kiddie pools are a fun and effective method of keeping cool while getting in some exercise.

3. Brushing your pets regularly can help keep them cool by removing excess fur. Avoid shaving or trimming the fur to short when grooming, as this can lead to sunburn. Pro tip: wet a cloth with cool water and pet your dog or cat with it. This aids in removing shed fur, as well as cooling.

4. Frozen treats are a great way to keep your pets cool! To help with hydration, freeze water with a bit of fruit for flavoring. (Avoid grapes and raisins, as these can be extremely toxic to animals.) Quick recipe: fill a yogurt cup or similar sized container with water, then stir in a tablespoon of plain applesauce (no sugar or cinnamon added). Pop in the freezer until solid.

5. When your pets are inside, ensure that the temperature stays cool by leaving the AC on. If you do not have AC, circulate the air with fans. Elevating their beds can also help by allowing air to flow underneath them.

6. Most importantly, never leave your pet in your car, and always allow them reprieve from direct sun. Fifteen minutes in 90 degree heat is enough to cause heat stroke in your pet. Always offer shade and/or the ability to come inside.
