Sensible methods for utilizing fireplace, grazing, and vegetation administration to create thriving grassland habitat for upland birds
When individuals consider grasslands, the image that involves thoughts is dependent upon the place they stay or hunt. Some could think about native prairies like these of the Flint Hills of Kansas or Sandhills of Nebraska. These areas have by no means been touched by the plow and signify a few of the very uncommon, intact remnant native grasslands remaining in the USA. For others, the Dakotas’ intensive fields of brome could come to thoughts, whereas for a lot of, a Conservation Reserve Program (CRP) area would pop into their head. Irrespective of your psychological image of a grassland, all of those landscapes might be managed for upland birds.
All of those locations are grasslands. Nevertheless, for the sake of this text, we’ll concentrate on habitat administration of enormous grassland landscapes, native and non-native alike. In one other article, we’ll delve particularly into CRP administration. When you haven’t learn the opening article of this four-part collection, “Upland Sport Fowl Habitat Necessities and Administration Ideas,” please learn it earlier than persevering with on. It’s a primer explaining fundamental upland chicken habitat wants that won’t be lined right here.
This text is a deeper dive into grassland administration methods that landowners can make use of in hopes of accelerating chicken numbers on their farm or ranch.
Sharp-tailed Grouse, Prairie Chickens, And Extra Dwell in Grasslands
The methods beneficial beneath are meant to assist enhance the manufacturing of sharp-tailed grouse and prairie chickens, and to a lesser extent, Hungarian partridge, pheasants, and bobwhite quail. Prairie grouse like sharptails and chickens require expansive areas of various grasslands. By expansive, we imply hundreds of acres of grasslands.
The time period grassland might be deceptive because it means that “grass” is an important part. Nevertheless, the fact is a range of broadleafed vegetation interspersed amongst the grasses, together with some scattered shrubby cowl, are what makes grasslands operate on the highest stage.
Giant grasslands additionally produce Huns and pheasants, however these areas don’t sometimes maximize their inhabitants numbers. Ideally suited habitat for these species is normally a mixture of grasslands interspersed with cropland. Bobwhite quail thrive in all types of habitats, and enormous grasslands in locations like Oklahoma and Texas are not any exception.
How Rainfall Shapes Grassland Habitat
If we take into account grasslands from North Dakota all the best way to West Texas, the quantity of precipitation makes a major distinction within the plant range and density. Moreover, the size of the rising season differs by a number of weeks, making the habitat vastly totally different. Nevertheless, all upland birds residing in grassland habitats have the identical necessities for nesting, brood rearing, and escape cowl.
Within the northern latitudes or greater rainfall areas (35+ inches yearly), nesting cowl isn’t a limiting issue. Grass is considerable and there are many locations to cover a clutch of eggs so long as the grassland isn’t overgrazed, or the complete panorama burned .

Brood-rearing habitat is often the most important concern in these landscapes. Grasses thicken, limiting the range of leafy vegetation whereas crowding out much-needed naked floor for chick mobility. Alternatively, extraordinarily dry grasslands present in western Oklahoma or Texas typically wrestle to supply satisfactory vegetation to even permit for nesting makes an attempt throughout droughty years.
The quantity of precipitation is one thing landowners can’t management. However contemplating the common circumstances primarily based on common rainfall must be factored into administration plans. A prescribed fireplace in japanese Kansas could solely present perfect brood cowl for 12 to 18 months, whereas a prescribed fireplace in western Kansas could change the vegetation construction for 4 or 5 years, even with out a drought.
Kinds of Grasslands
When you personal or handle a grassland that consists of native vegetation, then you’re effectively in your method to high quality habitat. In northern states the place brome abounds, sharpie and hen manufacturing might be profitable, even though brome is non-native. Nevertheless, most different non-native grasslands are poor for upland chicken manufacturing.

Fescue dominates a lot of the japanese United States grasslands. Within the South, bermuda or bahiagrass covers numerous acres the place native vegetation as soon as existed. Fescue, bermuda, and bahia grasses type a blanket of sod throughout the bottom, leaving little room for forbs and naked floor. This ends in an almost inconceivable state of affairs for broods to achieve success. Most native grasses develop in clumps, leaving area between vegetation for forbs to develop and naked floor to persist.
One of many quickest methods to enhance recreation chicken habitat the place non-native grasses dominate is to transform these acres into fascinating species. This may be completed in quite a lot of methods. Oftentimes, merely spraying the non-native grass with an acceptable herbicide and permitting the seed financial institution to reply will yield a flush of native vegetation from seeds which were laying within the floor for years, ready for a possibility to thrive. In different circumstances, spraying out the undesirable grasses might be adopted by planting a mixture of native forbs and grasses.
Remember the fact that website preparation is necessary previous to spraying. It’s crucial to make sure good chemical contact with the vegetation. Burning or haying might be an efficient method to cut back the vegetation peak and thatch. Permit the world to regrow, then spray when the vegetation reaches eight to 12 inches in peak. Fescue, a cool season non-native, can simply be eliminated with any herbicide containing glyphosate. Heat season non-natives like bermuda or bahia want a bit of extra kick, so herbicides containing imazapyr are most well-liked.
When able to plant native forbs and grasses, we sometimes suggest landowners make the most of native ecotype seed and plant extra forbs than grasses to maximise the attractiveness for recreation chicken broods. In brome nation, the interseeding of alfalfa can spike brood success as a result of alfalfa attracts an infinite variety of invertebrates.
The Function of Fireplace and Grazing in Grassland Administration
All grasslands advanced with disturbance. Traditionally, fireplace and grazing formed these landscapes. Fireplace stored bushes at bay and grazing animals created a mosaic of vegetation construction and plant range. In the present day, each fireplace and grazing can be utilized individually or together with each other to create prime habitat for upland birds.
When utilizing prescribed fireplace, the frequency of its use is an important consideration. The time of yr of a fireplace also can make a distinction within the subsequent vegetation response. Early spring burns have a tendency to extend grass vigor whereas fall or winter burns can cut back grass vigor, thus growing forbs. Our quail analysis in Missouri confirmed broods spent the vast majority of their time in grassland areas that have been both burned or grazed inside the earlier twelve months. Areas that have been idle for longer than a yr obtained minimal use, doubtless because of the vegetation changing into too thick with restricted naked floor.
Prescribed Fireplace
If you’re a landowner contemplating how typically to make the most of fireplace, you should routinely examine the habitat situation to determine when the grass has develop into too dominant or naked floor too scarce resulting from extreme thatch. As a normal rule, areas that common 35+ inches of rainfall yearly should be burned no less than as soon as each three years. Areas the place annual rainfall averages lower than 20 inches can use a 5 – 6 yr fireplace return interval.
Burn unit measurement should even be thought of. Consider birds can’t nest in a burn unit in the course of the early portion of the breeding season since there is not going to be satisfactory vegetation to cover a nest and the incubating grownup. Birds will make the most of unburned models to nest after which favor burned models for brood rearing. The shorter the space birds need to relocate from the nest to high quality brood rearing habitat, the higher likelihood the brood will get a profitable begin. In greater rainfall areas the place the burn interval is shorter, smaller burn models are most well-liked. Smaller is all relative. If managing a ten,000-acre grassland, burn models of 500 acres may be acceptable, whereas 100-acre burn models or smaller can be most well-liked on a 1,000-acre grassland.
Prescriptive Grazing
Grazing is an alternative choice for creating disturbance in grasslands in an effort to enhance upland chicken habitat suitability. In lots of components of the nation, grazing adversely impacts habitat high quality resulting from extreme stocking charges. This isn’t as a result of grazing itself is dangerous, fairly it’s the depth of the grazing that dictates the quantity of vegetation eliminated and the way a lot stays.
We regularly name our grazing prescriptions “conservation grazing.” That is the place we make the most of cattle to form the habitat in an effort to maximise usable area for recreation chicken manufacturing, fairly than maximizing cattle manufacturing. Don’t misunderstand, there’s cash to be constructed from the cattle utilized in conservation grazing, however the high precedence is habitat administration, not cattle earnings.
Grazing gives flexibility to regulate the stocking fee or grazing length inside a rising season primarily based on environmental circumstances, notably rainfall. If the summer time seems abnormally dry, cattle might be eliminated fully or the stocking fee decreased to forestall overgrazing. Quite the opposite, if a moist summer time ends in thick vegetation, the herd might be left on website into the autumn to scale back grass dominance, which can lead to extra forbs the next spring and summer time.
Utilizing Fireplace and Cattle Collectively
The last word purpose of conservation grazing is to create quite a lot of vegetation heights, cut back grass dominance, and take away thatch, thus growing naked floor. We sometimes accomplish this by grazing complete pastures as one unit, not with rotational or excessive depth grazing regimes.
Burning a portion of a pasture within the spring can extra dramatically create a mosaic of vegetation heights. The cattle will spend extra time grazing the regrowth within the burned space, thus grazing it shorter, creating high quality brood cowl. They may spend much less time within the unburned parts, thus leaving these areas for perfect nesting cowl. We make the most of this method on a number of grasslands in our dwelling state of Missouri.
Grazed areas needs to be monitored recurrently. Generally, vegetation shouldn’t be grazed beneath shin peak. If parts of a pasture develop into overgrazed because of the location of water or different options that entice cattle, that’s acceptable and truly fascinating. These shorter grazed areas typically present lekking areas for prairie chickens and sharptails and lots of songbirds require one of these habitat as effectively.
Shrubs and Woody Crops are Escape Cowl
The ultimate piece of the puzzle is offering woody or brushy cowl for birds to make use of as escape cowl. This escape cowl is used for shade in the summertime, refuge from harsh climate within the winter, and escape predation year-round. In some circumstances, stiff herbaceous vegetation can function a surrogate for woody escape cowl, like a patch of untamed sunflowers or kochia.
Species like quail or Huns want a substantial quantity of escape cowl distributed throughout the panorama. For prairie grouse, escape cowl can also be necessary, however the amount wanted is way decrease than vital for quail. Within the north, species like snowberry function escape cowl and winter meals for sharp-tails. In different areas, wild plum and dogwood are the first shrub thickets that recreation birds make the most of. In arid environments, shinnery oak, younger mesquite thickets, and even prickly pear cacti can present a lot wanted escape cowl for quail.
Whatever the species, the administration of escape cowl might be difficult. In lots of areas, extreme woody encroachment threatens grasslands. Cedar bushes throughout a lot of the Midwest have destroyed the performance of hundreds of acres of grasslands for the birds that rely on open areas. Eradicating undesirable bushes is a fundamental part of grassland administration. Even shrubby species can take over in areas with vital rainfall—sumac and dogwood might be very aggressive. Scattered thickets of those species are fascinating, however widespread dominance just isn’t.
Prescribed fireplace or chemical therapies are generally required to maintain extreme shrub protection in verify. Quite the opposite, some grasslands lack the required escape cowl wanted to optimize recreation chicken manufacturing. Defending growing thickets from destruction by cattle or fireplace can permit them to achieve a practical peak and retain the power to resprout after a hearth.
Consider Your Grasslands and Take Motion
Ultimately, every property have to be evaluated primarily based on its present and potential future situation. Landowners and managers should assess the limiting components on their property or every administration unit. On some properties, a number of points are limiting recreation chicken manufacturing. On others, only one part wants adjustment. Most of the time, once we tour non-public farms and ranches, high quality brood-rearing cowl is probably the most limiting issue. Sustaining high quality brood-rearing habitat takes extra work than managing the opposite sides of recreation chicken habitat, which is probably going why it’s the very first thing to fall into an unusable state.
Get out and do some habitat analysis. Contemplate all of the elements vital for achievement and determine the deficiencies in usable habitat. Make a plan to appropriate these deficiencies before later. The satisfaction of looking birds on land the place you efficiently manipulated the habitat and noticed a optimistic response is a sense you gained’t quickly overlook.
