- Habitat · Land, maps and imageryIsle Royale Wolves Used Beaver-Lodge Areas Most in FallCollared Isle Royale wolves used ground near active beaver lodges most in fall, peaking in October, but the collars could not tell a pass from a hunt.
- Habitat · Land, maps and imageryMore Bi-State Nest and Brood Map Area Ranked Low for SurvivalOn Bi-State nesting and brood maps, about 729 square miles ranked high or moderate for use and low for predicted survival, versus about 531 square miles ranked well for both.
- Habitat · Land, maps and imageryPlains sharp-tailed grouse leks tracked surrounding grasslandA southern Saskatchewan model ranked grassland in the roughly 3-mile square centered on plains sharp-tailed grouse leks above the pixel under them.
- Habitat · Land, maps and imageryFawn Deaths, Coyotes and the Results of TrappingAcross a review covering 29 populations, predators accounted for the most fawn deaths. A South Carolina experiment reduced an index based on coyote scat by 78%, but survival of fawns reached 51%, 20% and 43% over three years. Identify what limits recruitment before spending on removal.80%of fawn deaths were coyote kills before trapping at Savannah River
- Habitat · Land, maps and imageryA Field That Grew Corn Last Year Probably Holds Beans This FallAcross Illinois, soybeans followed corn on about 76 out of every 100 acres, while corn followed soybeans on about 82 out of every 100 acres. Use those chances to interpret older aerials and crop maps, then check harvest timing before heading into the field.82.9%of Illinois corn and soybean acres switched crops year to year
- Habitat · Land, maps and imageryDoes the Pond on Your Map Still Have Water? Consult County Drought History Before Hanging Your StandWhen the reporting week closed 13 October 2025, severe or more intense drought covered a quarter or greater share of land in 50 Illinois counties out of 102. Throughout June to August, the weekly count never exceeded 3. Here's how county drought history helps you assess a pond marked from imagery.50Illinois counties with qualifying D2 or worse drought, week ending 13 October 2025
- Habitat · Land, maps and imageryBefore Studying the Woods, Check the Layer: Pixel Width, Image Age, and Leaf StatusBefore using an aerial to judge bedding cover, identify the layer, check its year, and divide the feature's width by a pixel's width. Our inventory contains 910 leaf-off county tile sets and has 2024 as its median year label; output at zoom-19 covers about 9 inches per pixel.0.51of a pixel: the width a 12-inch feature spans in a 23.6-inch pixel
- Habitat · Land, maps and imageryCheck Soil Maps Before Offering to Buy Deer LandBetter feed in Mississippi State's trials erased a 25-inch difference in antler scores across soil regions. Our source review found nothing connecting a parcel soil map with antler score. Eight federal layers available at no cost still describe growing potential and flood exposure, while county context offers clues about neighboring plantings.+28 inchesantler score gained by Lower Coastal Plain bucks on one shared diet
- Habitat · Land, maps and imageryWhat a Leaf-On Aerial Can and Cannot Tell You About CoverA photo taken during the growing season records vegetation tops for that day. Assign each dark area to one of five classes. Use a winter view or a walk along its downwind boundary to determine whether it qualifies as cover.20 yardsthe chest-level sight line used to judge whether a dark patch is cover
- Habitat · Land, maps and imageryYour Pin Is Older Than the Field: Check Two Image DatesA pin you saved makes a statement about the land as it was last year. Check the date of the image beneath it, compare it with another dated image, and complete a brief worksheet before hunting that spot again.15 to 50 yearsof regrowth a woodlot can need after a timber harvest

Six evidence rungs distinguish map drawings, sign, recurring sign and individually recognized animals, helping you see what you actually have.Sixevidence rungs, from a map drawing to a recognized animal
- Habitat · Land, maps and imageryReading the Ground: What LIDAR Shows That Satellite Can'tAn aerial photo captures the woods from above, showing the green treetops. The forest floor hidden under that canopy, where deer travel, stays out of view. Laser terrain mapping reveals that ground and the features that determine how a hunt plays out: a bench, a saddle, or a ditch that funnels most of a drainage through one crossing.
- Habitat · Land, maps and imageryThe Sun Budget: Why a Cold-Season South Slope Is Worth More Than It LooksThe cost of winter warmth helps shape deer bedding. Low sun gives a slope facing it hours its neighbor across a draw misses. This terrain layer, the third, describes the ground's daily energy budget hunters sense but rarely measure.0 to 10 hoursof direct winter sun per day across Illinois
- Habitat · Land, maps and imageryPick the Tree, Not the RidgeSpring turkey hunts fall during bare-canopy season, the year's only chance for aerial photos to show branches instead of leafy surfaces. With pixels three to six inches wide, a roost tree becomes a distinct object you can pick out.3 to 6 inchespixel size of our bare-canopy county imagery
- Habitat · Land, maps and imageryThe East Bench Really Does Win the MorningA familiar turkey rule points gobblers toward slopes lit earliest. We tested it throughout an Illinois county, using each bench's visible terrain horizon. This time, the lore holds; shade occurs more often as slopes steepen.95.8%of east and southeast benches in Edgar County are in sun by fly-down
- Habitat · Land, maps and imageryRank Your Strut Benches by Morning Sun, Not by GutOn aerial images, openings on the same ground can appear exactly alike. Yet during the first two hours after sunrise in Edgar County, benches getting the most sun receive more than double the direct sunlight of those getting the least. You can work out that difference before setting foot there.2.5×sunlight on the best bench against the worst, first two hours after sunrise
- Habitat · Land, maps and imageryReading a Bench, Saddle, and Draw on a Topo MapThree terrain features determine deer travel routes and bedding spots: how each appears on a contour map, how deer use it, and why a large elevation interval between contour lines keeps half of them from showing up.10 or 20 feettypical contour spacing, which leaves out the most useful terrain
