Nebraska Nature Guide: March 2026
March is Nebraska's headline month. Roughly half a million Sandhill Cranes pack the Central Platte near Kearney and Grand Island in the single greatest crane gathering on Earth, joined by millions of geese and ducks pouring up the Central Flyway. The prairie greens, the first wildflowers open, and the grouse begin to dance.
What to look for this week
- Feeders are at their winter peak across Nebraska — chickadees, nuthatches, and cardinals work the seed, while bald eagles already gather at open water below the Platte dams and around Lake McConaughy.
- The Quadrantid meteor shower peaks in a short, sharp burst around January 3; watch after midnight from a dark Sandhills site such as Merritt Reservoir.
- A planning week — order seeds and favor short-season varieties that finish in the cold Sandhills and panhandle corner of the state.
- The massive bare cottonwoods along the Platte and Missouri show their winter silhouettes, the state tree's furrowed gray bark stark against the snow.
Birds This Month
March is the marquee of Nebraska's birding year. The Sandhill Crane migration peaks on the Central Platte between Kearney and Grand Island, where roughly half a million cranes — about eighty percent of the world's population — roost on the river's sandbars and feed in the surrounding cornfields, the greatest crane concentration on the planet. Dawn and dusk at the Rowe Sanctuary and the Fort Kearny hike-bike bridge, as the cranes lift off or settle onto the river in roaring clouds, is one of North America's great wildlife spectacles. Watch among them for the rare, endangered whooping crane passing through.
With the cranes come staggering numbers of geese — snow geese, Ross's geese, greater white-fronted geese, and Canada geese — staging in the Rainwater Basin marshes, along with northern pintails and clouds of dabbling ducks. On the prairie, greater prairie-chickens and sharp-tailed grouse begin booming and dancing on their Sandhills leks, and western meadowlarks sing from fence posts.
This month's tip: book a crane blind at Rowe Sanctuary well ahead, arrive before dawn, and let the sound of the river come to life around you.
What's Blooming
March brings Nebraska's first true wildflowers. On dry, gravelly hill prairies and bluffs, the lavender cups of the pasque flower open in the last weeks of the month, sometimes pushing up through lingering snow — the prairie's earliest bloom. In the eastern woodlands along the Missouri and lower Platte, the first spring ephemerals stir: the upright white-and-yellow of bloodroot, and the green spears of emerging trout lily and Dutchman's breeches in sheltered ravines.
Streamside willows and the river cottonwoods hang heavy with catkins, the silver maples and boxelders color the bottomlands with their tiny flowers, and in town gardens the snowdrops, crocus, and winter aconite bloom in earnest. By month's end the first daffodils open in the milder southeast. After a long, brown winter, March is when color and growth return to the Nebraska landscape.
Garden This Month
March is when the Nebraska garden finally moves outdoors. As the soil dries and warms enough to be worked without clumping, direct-sow the cool-season crops — peas, spinach, lettuce, radishes, beets, carrots, and chard — and plant onion sets, seed potatoes, and asparagus crowns. Transplant broccoli, cabbage, and kale that you started indoors, and set out cold-tolerant pansies and early greens. Keep floating row cover on hand, because a hard freeze or a wet, heavy snow can still arrive at any time in a Nebraska March.
Indoors, start the warm-season crops — tomatoes, peppers, and eggplant — under lights for transplanting after the frost-free date in May. Outdoors, prune roses and summer-blooming shrubs as buds swell, cut back ornamental grasses before new growth begins, rake winter debris off the beds once the soil firms, and pull back heavy mulch from emerging perennials. The growing year has begun.
Zone 4b (Sandhills and panhandle): still early and cold here — start the bulk of your transplants indoors, prune fruit trees, and hold off on outdoor sowing until April, though peas and spinach can go in under cover at month's end on the most sheltered, south-facing ground.
Zone 5a (central Nebraska): as the soil dries and warms, sow peas, spinach, radishes, and lettuce outdoors and set out onion sets; keep row cover handy, because hard March freezes and late snow are routine in the Platte Valley.
Zone 5b (southeast, lower Missouri Valley): the season opens here — direct-sow peas, spinach, lettuce, radishes, beets, and carrots, plant onions and potatoes, and transplant broccoli and cabbage as the soil becomes workable.
What's at the Farmers Market
Nebraska's markets are still in their lean late-winter stretch, but the first fresh growth appears. Indoor and early-season markets in Omaha and Lincoln carry the last firm storage onions, potatoes, carrots, beets, and winter squash, and the first cuttings from hoop houses — spinach, lettuce, arugula, and other tender greens — begin to brighten the stands.
This is the start of maple syrup season from the eastern Nebraska timber, where a handful of producers tap sugar and silver maples along the rivers, and honey from last year remains a staple. Look for farm eggs, grass-fed Sandhills beef and pork, and the first microgreens and radishes of the new season. Choose the freshest greens you can find and refrigerate them promptly, and use the last storage roots before they soften as spring approaches.
Night Sky This Month
March balances day and night at the spring equinox near March 20, and the evening sky pivots from winter to spring across Nebraska. The state's darkest skies remain the Sandhills around Valentine and Merritt Reservoir, the Niobrara valley, and the panhandle's Wildcat Hills — far from any city glow, where the transition is most vivid.
In the early evening, Orion and the Winter Hexagon still hold the southwest, but they sink earlier each night as Leo, with its backward-question-mark Sickle and bright Regulus, climbs in the east. Following Leo come Virgo and the Big Dipper, riding high overhead and pointing its handle to orange Arcturus rising late. Spring is galaxy season — the realm of Leo and Virgo holds countless faint galaxies for a telescope under the Sandhills' dark sky.

Butterflies & Pollinators
March brings the first butterflies of the Nebraska year on its warmest afternoons. The overwintering adults emerge to fly over the still-brown prairie and along the river timber: the mourning cloak, with its deep maroon wings and cream borders, is usually the first, basking on sun-warmed cottonwood trunks and gliding through bottomland woods on days that climb into the fifties and sixties. With it appear the eastern comma and question mark, anglewings that also overwinter as adults and seek out tree sap and mud.
By late March, the first cabbage whites flutter over gardens and field edges, and in the warm southeast the earliest spring azures may appear in woodland openings. These are still scattered sightings on isolated warm days rather than a true flush — the prairie's great butterfly season is two months away — but each one is a real sign that the Nebraska year is turning. Resist tidying every bit of leaf litter and brush, since it still shelters dormant chrysalises and the first caterpillars.
Trees This Month
March wakes Nebraska's trees. The bottomland forest leads: streamside willows flush gold and silver with catkins, the silver maples open their tiny red and yellow flowers before any leaves, and the boxelders and elms bloom along the Platte and Missouri. The eastern cottonwoods, the state tree, hang their reddish catkins from the riverbank giants late in the month.
On the dry uplands the bur oaks still hold tight buds, slower to wake, and the eastern redcedars take on a rusty cast as the male trees prepare to release clouds of pollen. In the panhandle, the ponderosa pines of the Pine Ridge stand dark and steady as the prairie greens below them. This is a fine time to plant bare-root trees and to finish any last dormant pruning before the leaves break — and to watch sapsuckers and the returning sap-feeding insects work the swelling maples and cottonwoods.
