A depression in grass, leaves, snow, or soil where an animal has lain down to rest, sleep, or chew cud. A deer bed is an oval of flattened vegetation, body-sized, often on a slope with a view of the approach below. The bed may hold warmth, scent, and shed hair — evidence of how long the animal stayed and how recently it left. Finding a warm bed means the animal heard you coming.

A shallow, bowl-shaped depression excavated by wind in an area of loose sand or soil — most commonly in dunes, beaches, or overgrazed rangeland where vegetation has been removed and the surface exposed to deflation. The wind scoops out the center, and the excavated material accumulates on the downwind side as a crescent-shaped deposit. Blowouts are scars — they mark places where the surface was broken and the wind found its way in.

Rough, deeply dissected terrain along the edges of a plateau, mesa, or river bluff — the eroded, broken country where flat land gives way to drainage. The Missouri Breaks, the Caprock Breaks. The word names the transition zone, the place where the level world breaks apart into gullies, ridges, and coulees.

Open grassland or savanna, especially in South America — the vast, treeless or lightly treed plains of Brazil's interior. The cerrado (wooded savanna) and campo limpo (clean grassland) together form one of the most biodiverse ecosystems in the tropics. The word names openness — land without trees, land you can see across.

A deep, dark, extraordinarily fertile soil formed under grassland in temperate continental climates — the legendary "black earth" of the Ukrainian and Russian steppes, the American Great Plains, and the Argentine Pampas. Chernozem is black because it is saturated with humus, built up over millennia by the annual growth and death of deep-rooted grasses. The topsoil can be three feet deep or more. It is the richest agricultural soil on earth, and the breadbaskets of the world sit on it.

A fence built in open rangeland not to enclose an area but to direct the movement of livestock, channeling them toward water, corrals, or a specific part of the range. Drift fences work with the animals' natural tendency to drift with the wind or toward water — they don't confine, they guide. Remnants of old drift fences mark the desert and grassland landscape of the West, their posts weathered to silver.

A shallow depression in dry soil where birds — quail, sparrows, turkeys, grouse — roll, fluff, and work dust into their feathers to control parasites. Once you've seen one, dust baths are easy to identify: They're oval depressions in bare, powdery soil, often in sunny spots, with wing impressions fanning outward from the center. They are used communally and repeatedly, the soil worn to a fine flour. A row of dust baths along a trail is a sign of resident birds, not transients.

The transition zone between two adjacent ecosystems — where forest meets grassland, where marsh meets upland, where tundra gives way to boreal forest. Ecotones are edges, and edges are where diversity concentrates: species from both adjacent communities overlap, and species adapted specifically to the boundary itself may be found nowhere else. The ecotone is not a line but a zone, and it is often the most interesting ground in the landscape.

A herbaceous flowering plant other than a grass — the wildflowers, the broadleaves, the things that bloom. In a meadow, the grasses are the background; the forbs are the color.

Heavy, sticky, clay-rich soil that becomes an impassable, shoe-swallowing, vehicle-trapping mire when wet. Gumbo is the bane of the Northern Plains — dry, it's hard as pavement; wet, it adheres to everything and multiplies. A truck in gumbo gains 50 pounds of mud per wheel per revolution.

 A communal display ground where male birds — grouse, prairie chickens, ruffs, birds of paradise — gather to perform competitive mating displays for watching females. The males dance, strut, call, inflate air sacs, fan feathers, and fight, each defending a tiny territory within the lek. The females observe, choose, mate, and leave. The lek is a theater — the stage, the audience, and the audition happening in one place.

The low-altitude grassland and bushveld of southern Africa, typically below 3,000 feet — hot, subtropical, and home to the big game that made the region famous. Distinct from the cooler, higher highveld.

 A cold, dry wind that sweeps across the Pampas of Argentina and Uruguay from the southwest, usually accompanying a cold front. It arrives suddenly, dropping temperatures and bringing brief, violent storms before clearing the sky.

A compact mass of indigestible material — fur, feathers, bone, insect exoskeletons, seeds — regurgitated by a bird of prey, an owl, a crow, or a gull. A pellet is not scat; it comes up, not down, and it preserves the prey's remains in a tidy package that can be pulled apart to reconstruct the bird's last several meals. Owl pellets found beneath a roost are a census of the local rodent population, delivered nightly.

A tropical or subtropical grassland with scattered trees — too dry for forest, too wet for desert. Savannas cover roughly a fifth of the earth's land surface, including the great plains of East Africa, the cerrado of Brazil, and the northern Australian outback. The defining character is openness with trees — enough grass to carry fire, enough trees to cast shade, and the interplay between the two maintained by climate, grazing, and flame.

A vast, flat, treeless grassland in a semi-arid continental climate — too dry for forest, too cold for desert, supporting grasses and low shrubs but few or no trees. The Eurasian steppe stretches from Hungary to Mongolia, the largest continuous grassland on earth. The word implies openness, wind, and distance — a landscape of horizon.

 A circle of stones on the ground marking where a tipi once stood — the rocks that held down the edges of the hide cover, left in place after the structure was taken down and the people moved on. Tipi rings are found across the Great Plains by the thousands, sometimes clustered in groups that indicate seasonal camps used repeatedly over generations. They are among the most understated and moving marks on the American landscape — just a ring of stones in the grass, and a whole way of life implied.

A tall, dense, freshwater marsh plant (bulrush) native to the western United States, growing in thick stands around lakes, marshes, and river deltas. Tule marshes once covered vast areas of California's Central Valley. The plant gives its name to tule fog — the dense, ground-level radiation fog that forms in the Central Valley in winter, reducing visibility to near zero.

A large, flat, grassy, treeless plain — or, in the American Southwest, a broad, low-lying area of fertile, well-watered ground along a river, suitable for cultivation. Las Vegas was named for the meadows that the springs there sustained in the desert.

Open grassland or savanna in southern Africa — the rolling, treeless expanse that stretches to the horizon. Veld is defined by altitude (highveld, lowveld, middleveld), by vegetation (bushveld, sweetveld, sourveld), and by the quality of light that fills it.

 A depression in the ground created by large animals — bison, elk, boar, rhinos — rolling and rubbing in mud or dust. Wallows serve multiple purposes: cooling, parasite removal, scent-marking, and social display. Old bison wallows on the Great Plains persisted for decades after the animals were gone, holding water and growing different vegetation than the surrounding grass — ghost baths.

Already entered in the main file — flagging here as a core tracking/sign term. A wallow is one of the most visible and long-lasting pieces of animal sign on a landscape. Bison wallows on the Great Plains were still identifiable decades after the herds were gone.

A line of trees, shrubs, or constructed fencing planted or erected to reduce wind speed and protect soil, crops, livestock, or buildings on the leeward side. Windbreaks are landscape features that shape the microclimate for hundreds of feet downwind — they reduce evaporation, prevent soil erosion, trap snow for moisture, and create shelter for wildlife. The Great Plains shelterbelt program of the 1930s planted 220 million trees in windbreaks stretching from Texas to North Dakota.
