# Selective land clearing in Denton, TX > Selective land clearing in Denton, TX: underbrush and marked trees removed while keeper post oaks and their root zones stay protected. Rules, methods, cost. URL: https://postoaklandclearingdenton.com/selective-clearing/ Underbrush, cedar and marked trees taken out while the post oaks and other keepers stay, with their root zones fenced off from machines. [Post Oak Land Clearing Denton](https://postoaklandclearingdenton.com/) offers and manages selective land clearing across Denton and the west and north of Denton County, with the work done by licensed and insured contractors. Selective clearing removes what you mark and protects the rest. The underbrush, the [cedar](https://postoaklandclearingdenton.com/cedar-clearing/) crowding the oaks, and the dead, leaning or crowded trees come out. The post oaks, elms and pecans you want stay, and so do the roots that keep them alive. It goes by other names too, underbrushing, thinning, underbrush clearing, and the idea is the same: a park-like woods or a homesite under shade rather than an open field. ## What happens on the first visit The first visit is a marking walk. Every tree that stays gets one color of ribbon, every tree that goes gets another, and the trunks that matter for permits are measured at 4.5 feet above the ground, the height Denton’s code uses. Multi-trunk trees are measured the code’s way: the largest stem plus half of each other stem. The walk also lays out how a machine gets around the keepers without driving over their roots, and where hand work has to take over. It looks for planned grade changes, such as a pad, drive or septic field near a keeper, because a few inches of fill over roots can do more harm than a machine passing by. And it settles the paperwork: whether the land is regulated under Denton’s tree rules, whether a creek buffer or mapped sensitive area touches it, and which trees need a permit before they come down. ## Root zones: where keeper trees actually get hurt Keeper trees are rarely killed by a machine bumping the trunk. They decline from what happens to their roots: tracks compacting wet clay, soil scraped off or piled on, grade changes and trenches. Most feeder roots sit in the top foot or so of soil and spread past the drip line, so damage happens well away from the trunk. Post oaks are known for poor tolerance of root disturbance, and the decline can take a few summers to show, as thinning crowns and dying limbs, long after the clearing has been paid for. On Denton’s clays the risk is sharper when the ground is wet, because compacted clay stops taking in water and air. A common arborist rule of thumb sets the protected radius at about 1 foot for every inch of trunk diameter; where a tree plan or permit draws the line, that line governs. Protection is physical, not a promise. Tree protection fencing goes up at the root zone edge before machines arrive. Inside it, nobody parks, fuels, piles brush or spreads thick mulch, and brush is cut by hand and carried out. Outside it, a mulcher works the understory with the head kept off the soil. Felled trees are dropped away from keepers and cut up where they land rather than dragged across roots. Inside Denton, when a tree removal permit is required, the city’s tree protection fencing inspection must pass before the permit is issued. Roanoke requires 4-foot protective fencing outside the critical root zone of protected trees within 50 feet of construction, and its checklist allows underbrush clearing within those root zones. Statewide, Texas A&M Forest Service oak wilt guidance is to paint fresh wounds on oaks right away, which is one more reason to keep blades off keeper bark. ## Denton’s heritage post oaks and the 30% floor In Denton, a post oak becomes a heritage tree at 6 inches in diameter, while most other species stay quality trees until 18 inches. On land the tree rules cover, a development must keep at least 30% of its heritage and quality tree diameter within the development impact area, so selective clearing is how a regulated tract gets built at all. The rules apply to undeveloped land, to nonresidential and multifamily redevelopment, and to a home lot only when the house is being demolished. A lot with an existing single-family home, agricultural operations and trees on the state noxious and invasive plant list are exempt, though the city still asks for an exemption submittal through Building Safety on eTRAKiT. Removal permits cost $425, and mitigation runs $200 per caliper inch where trees are not preserved or replaced. Texas law bars a city from charging a mitigation fee for a tree under 10 inches on an owner’s own home lot. A healthy redcedar 6 to 18 inches across on regulated land counts as a quality tree, while mesquite and honey locust are unprotected, so thinning cedar and mesquite out from under post oaks often costs far less in permits than people expect. The city is reviewing its tree rules, and the [Denton tree removal permit guide](https://postoaklandclearingdenton.com/guide/denton-tree-removal-permit/) follows the current text. Large woods add one more layer. Where contiguous Cross Timbers woods reach about 10 acres, Denton can map them as Cross Timbers Upland Habitat, and residential development there keeps a contiguous 50% predominantly natural. Creek buffers are stricter still, with tree and understory removal prohibited; the [creeks and floodplains guide](https://postoaklandclearingdenton.com/guide/clearing-near-creeks-and-floodplains/) covers both. ## Trails, views and thinning Selective clearing covers more than homesites. A walking or mowing trail is a narrow corridor wound between keepers: the line is flagged first, saplings and brush along it are mulched or cut flush, and where a keeper’s roots cross the route, the trail stays at grade rather than being dug in. Width follows the use, a footpath, a mower deck or a utility vehicle, and is agreed before cutting. View corridors and thinning work the same way at a larger scale. Crowded trees compete for light and water, so taking out the weaker stems in a cluster can leave the remaining oaks with fuller crowns over time. The understory that comes out is usually mulched in place and spread thin, which covers the ground without smothering keeper roots; heaped mulch against a trunk holds moisture on the bark and is avoided. Resprouting brush under the keepers will need a follow-up season or two, as the [regrowth guide](https://postoaklandclearingdenton.com/guide/keeping-brush-from-growing-back/) explains. ## Selective clearing or clearing everything Complete clearing is faster and cheaper per acre and fits ground that will be built on, paved or turned to open pasture. Selective clearing fits ground where the trees are the value: shade, privacy, the look of Cross Timbers woods. Many lots need both, a fully cleared footprint and a selectively cleared remainder. The split is usually drawn on the plan. The house pad and drive are [lot clearing](https://postoaklandclearingdenton.com/lot-clearing/) followed by [grubbing](https://postoaklandclearingdenton.com/clearing-and-grubbing/), the yard around them keeps its best trees, and a buffer of woods stays along the back line. Clearing everything and replanting rarely comes out ahead: a nursery tree takes decades to reach the shade of a mature post oak, and inside Denton the trees removed carry mitigation. There is no reliable percentage for how much trees add to a lot’s value, but shade and mature trees are much of the reason to own a wooded lot in the first place.

Typical North Texas land clearing ranges are the reference: $1,500 to $3,500 an acre for light brush and small trees, $2,500 to $4,500 for moderate growth with trees up to about 8 inches. Selective jobs tend to sit higher within or above those ranges for the same growth, because a machine working around keepers covers less ground in a day and hand work fills the gaps. The drivers are the number of keepers and how close they stand, the share of the area inside fencing that has to be cut by hand, the size of trees marked for removal, permits and mitigation inside Denton, debris volume and whether mulch can stay, and wet clay that pushes work to drier weeks. The [land clearing cost calculator](https://postoaklandclearingdenton.com/tools/land-clearing-cost-calculator/) gives a starting range, and the [cost per acre guide](https://postoaklandclearingdenton.com/guide/land-clearing-cost-per-acre/) explains how each driver moves it. Thick brush with few trees to work around is closer to [brush clearing](https://postoaklandclearingdenton.com/brush-clearing/) or [forestry mulching](https://postoaklandclearingdenton.com/forestry-mulching/) in price. ## What's included - A walk to mark every keeper and every tree to remove, with trunk diameters measured at 4.5 ft - Machine routes and work zones laid out so tracks stay off keeper root zones - Tree protection fencing at the root zone edge where the permit or the plan requires it - Underbrush, vines and saplings removed, by machine outside the fencing and by hand inside it - Marked trees felled away from keepers and cut up without dragging across root zones - Mulch spread thin, never heaped against keeper trunks or piled over roots - Trails or view corridors cut to an agreed width, stumps flush - A note of what was kept, what came out and any permit or mitigation filed ## Selective clearing compared with complete clearing and with hand thinning only *Selective clearing compared with complete clearing and with hand thinning only* | Option | Selective clearing | Complete clearing | Hand thinning only | | --- | --- | --- | --- | | What comes out | Underbrush plus the trees marked for removal | Everything inside the limits | Small brush and saplings a crew can cut | | Keeper trees | Marked, fenced and worked around | None, unless kept outside the limits | Kept; no machines near them | | Root zones | Protected from tracks, scraping and fill | Not a concern; soil is opened | Barely touched | | Speed | Slower per acre than full clearing | Fastest per acre | Slowest; days of saw work | | Tree rules in Denton | Preserved trees count toward the 30% floor | Mitigation on every protected inch removed | Usually below protected sizes | | Fits | Homesites under oaks, park-like acreage, trails | Pads, drives, open pasture | Small areas, creek edges, steep banks | ## Related resources - [Do you need a City of Denton tree removal permit?](https://postoaklandclearingdenton.com/guide/denton-tree-removal-permit/): Which Denton properties the tree code reaches, which trees it protects, how preservation and mitigation are counted, and what to file before a saw starts. - [Can you clear brush along a creek or in a floodplain around Denton?](https://postoaklandclearingdenton.com/guide/clearing-near-creeks-and-floodplains/): Why creek banks and floodplains are the most restricted ground to clear around Denton, how to tell whether a lot is affected, and what work is still possible. - [What does clearing land to build a house involve?](https://postoaklandclearingdenton.com/guide/clearing-land-to-build-a-house/): The order a homesite is cleared in, from staking the footprint to the grading handoff, and why cleared ground is still not a building pad. - [How do you keep brush from growing back after clearing?](https://postoaklandclearingdenton.com/guide/keeping-brush-from-growing-back/): Brush comes back from roots and from seed.

As a rule of thumb, tracks stay outside a circle of about 1 foot of radius for every inch of trunk diameter, so a 16-inch post oak gets roughly 16 feet. Where a permit or tree plan draws the line, that line governs. Inside it, brush is cut by hand, and nothing is parked, piled or scraped over the roots. ### Does a post oak smaller than 6 inches count as a heritage tree in Denton? No. Under the Denton Development Code, post oaks become heritage trees at 6 inches in diameter measured 4.5 feet above the ground. A smaller post oak is unprotected by size, though the city's tree removal page still asks for a permit submittal for any tree removal, and exemptions apply to occupied home lots and agricultural operations. ### Can underbrush be cleared under the trees without a Denton permit? On a lot with an existing house, ordinary yard maintenance generally sits outside the land-disturbance permit. On undeveloped land, clearing vegetation past 2,000 square feet or 25 cubic yards of disturbance needs the clearing and grading permit unless exempt, and creek buffers and mapped sensitive areas limit understory removal outright. ### Can a walking trail be cut through the woods without taking any trees? Usually, if the route bends around trunks. The trail line is walked and flagged first, then brush and saplings are mulched or cut flush along it at an agreed width. Where a keeper's roots cross the line, the trail surface stays at grade instead of being dug in, so the roots are not cut. ### Who works around the keeper trees on a selective clearing job? Licensed and insured contractors do the clearing and the hand work around keepers. Post Oak Land Clearing Denton offers and manages the job, including the marking walk, the routes, the permit list and the final check of what was kept. ## Related services ### [Lot clearing](https://postoaklandclearingdenton.com/lot-clearing/) Trees and brush cleared from a home site or wooded lot, with the keepers, the drive corridor and the debris planned before a saw starts. ### [Forestry mulching](https://postoaklandclearingdenton.com/forestry-mulching/) Brush, cedar and small trees ground in place into a mulch layer, with stumps left at grade and roots holding the soil. ### [Brush clearing](https://postoaklandclearingdenton.com/brush-clearing/) Yaupon, greenbrier, privet, vines and saplings taken out of the understory by cutting, mulching or grubbing, matched to how much regrowth you can live with.
