Summertime Strategies

Wow, it’s hot out there in the high desert! At least much of the time … not so much at night … and not every day either. (I can clearly recall July 4, 2010, when, camped out on the West Little Owyhee River, we got 4” of snow overnight and all our water was frozen by the 24-degree dawn temperatures!) But, overall, no matter the actual daily weather, the sun is the driving force behind just about everything happening June to September.

Desert plants and animals adapt in their own ways: finding shade, burrowing down or hiding out during the day, moving to higher elevations, shedding winter fur coats, sending down deeper and deeper roots, maturing seeds and dropping foliage, and especially searching for water and food. Riparian corridors are increasingly vital now, even as they are drying up, as only a select few animals do not actually need water to drink.

Here’s an overview of strategies that the various groups of desert inhabitants will employ during this trying season when the sun makes water more scarce, complicating survival for most residents.

“I came to Oregon 12 years ago from Texas. Texas, for all its size, has very little public land. Coming to Oregon has made me realize the special gift we as Americans have in our public lands. Volunteering with an organization like ONDA is my way of reciprocating for this gift. Through restoration efforts, I feel we are helping leave a better place than we found it. Through advocating for protection for public lands, we safeguard migration routes for animals and keep the land where it belongs: with the public.”

“I contribute to ONDA monthly because it adds up to a larger annual gift than what I’d be able to comfortably afford if I were to do a simple one-time donation annually. I’m able to give more to ONDA this way and have greater impact which is important to me, and my dog Polly.”


Most baby mammals have grown up enough to begin to forage or hunt for themselves. For many predators, these inexperienced youngsters can provide more abundant, and easier to catch, meals. To offset losses, many rodents or lagomorphs (rabbits and hares) will birth multiple broods, with babies maturing rapidly to take advantage of abundant spring foods, especially in good years. For slower to mature animals, such as deer, pronghorn and coyotes, the young will spend more time with parents and perhaps older siblings and associates learning the ways of their world. Those that can might migrate up to higher elevations to escape the intense hot and dry conditions lower down, and thereby find better browse or grazing—or maybe a nice fawn to eat.

Reptiles and Amphibians

Amphibians tend to search out cool rocks to shelter under, with some digging a burrow in which to pass the worst of the heat. Reptiles also hide from the hottest parts of the day, sleeping under shady rocks and ledges, or in other densely shaded spots, perhaps crawling or slithering out to warm up at dawn, and many will begin hunting at dusk.

Birds may search for new hunting or foraging areas, depending upon their food source availability, often heading to higher altitudes following insects, or foraging for maturing seeds. Interestingly, there’s less birdsong in summer, as mating and nesting has already taken place.

Insects, and the bats that follow

Insects are looking for sources of nectar, leaves to chew, or other insects to eat. Spiders hunt the insects, so look into and around those blooms for them. Bats follow bugs, so wherever there’s the one you’ll probably find the other.


For plants, many will droop, and some even drop, leaves to reduce water loss, or may turn their leaves perpendicular to the sun’s rays to reduce exposure. Waxy coatings, surface hairs and increased levels of certain sun-screening pigments can also come into play in reducing sunlight exposure and protecting from desiccation. Perennials and shrubs drop tap roots more deeply into the moist layers below the easier-to-find water from winter and spring soils. Seeds mature and plants begin to jettison them to let their progeny live on in the future, awaiting next spring when there’s enough moisture again. Many desert seeds will sport spikes, hooks, barbs and “Velcro” to snag the fur or feathers of passing critters and transport their seeds to new areas. Most desert grasses are a bunch-grass form, and have densely packed foliage shaped like an open vase, which helps to collect any dew and precipitation that might fall in thunderstorms and direct it to their dense root ball just below the soil. Over time many desert plants develop a sort of a distributive sharing strategy, living just far enough apart to not hog each other’s water—thus, the clumpy desert landscape pattern. No lawn-like grasses here! The invasive weed cheat grass takes a different tack. Rather than cooperating, it “cheats” by sprouting early and maturing seeds rapidly, ahead of the native perennials, in order to spread widely over large areas.

As you watch the changes in the desert landscape, try to work out what strategies are at play where. You might observe avoidance, adaptation, behavior change, highly efficient use of available resources, competition, migration (both over distance or up in elevation) and estivation, which is prolonged torpor or dormancy during a hot or dry period. With time, you’ll learn to predict where you’ll be more likely to see particular species or activities. And, you will likely employ your own strategies like movement, exploration, converging upon water sources, and perhaps avoiding activity during the hottest parts of the day and instead relaxing in the shade with a book and a cold beverage!
