The capacity of many broadleaf (angiosperm) tree species to regenerate new shoots from the stump or root system after the main stem has been cut. In the context of coppice management, the relevant mechanism is epicormic sprouting from the cut stump: dormant bud precursors in the vascular cambium of the stump are released from apical dominance when the aerial stem is removed, and subsequently develop into vigorous new shoots. This capacity is the biological foundation of coppice silviculture — without it, repeated cutting would simply kill the tree. Not all tree species regenerate well in this way: conifers (Pinus, Picea, Abies, Larix) typically do not regenerate from cut stumps, while most temperate broadleaves (hazel, oak, ash, sweet chestnut, hornbeam, alder, birch) do so reliably.

Claims
- Coppice regrowth in broadleaf trees proceeds from epicormic buds (bud precursors in the vascular cambium under the bark of the cut stem base), not from root suckers. (confidence 0.92; sources: CIT-VR-01)
- Explicitly stated and the misconception about ‘suckers’ explicitly corrected in CIT-VR-01. This is well-established plant biology. Confidence 0.92 — high confidence in the mechanism as stated; small uncertainty because the Wikipedia article itself does not cite a primary botanical source for this passage, though the mechanism is consistent with standard plant physiology.
- The trigger for epicormic bud activation is the removal of apical dominance: the cut aerial stem had been producing inhibitory plant hormone analogues (principally auxin) that suppressed lateral and dormant bud growth; cutting removes this inhibitory signal and dormant cambium bud precursors develop into new shoots. (confidence 0.9; sources: CIT-VR-01)
- CIT-VR-01 states ‘Epicormic buds develop and grow when the upper parts of the stem (which normally produce inhibitory plant hormone analogues) are removed.’ The specific hormone is not named in this source; the broader apical dominance mechanism is standard plant physiology. Confidence 0.90 — the mechanism is well-established; the Wikipedia source does not name auxin specifically, but this is consistent with standard botanical knowledge.
- Most temperate broadleaf species (hazel, oak, ash, sweet chestnut, hornbeam, alder, birch) regenerate well from cut stumps; conifer species (Pinus, Picea, Abies, Larix) typically do not. (confidence 0.9; sources: CIT-VR-01)
- Directly supported by the species list in CIT-VR-01 and the statement that coppicing has been practised for millennia on these broadleaf species. The inability of conifers to regenerate from cut stumps is well-established silvicultural knowledge and consistent with the complete absence of conifer coppice as a silvicultural practice. Confidence 0.90.
- First-year regrowth from coppiced hazel stools can reach 1–2 m, substantially outpacing seedling growth, because the root system retains its full resource base from the pre-coppicing tree. (confidence 0.88; sources: CIT-VR-01)
- Stated in the Coppice Woodland Management procedure node (Step 7, citing CIT-COP-01 = same source as CIT-VR-01 here). The root-resource explanation is given in the Wikipedia Coppicing article. Confidence 0.88 — the vigour of coppice regrowth is well-documented; the specific ‘1–2 m’ figure for hazel is consistent with practitioner knowledge and appears in multiple coppice management references, though CIT-VR-01 itself does not give an explicit measurement.
Needs verification
The specific inhibitory plant hormone responsible for apical dominance suppression of epicormic bud growth (implied to be auxin in standard plant physiology). (non-blocking)
CIT-VR-01 refers to ‘inhibitory plant hormone analogues’ without naming auxin. This is standard plant physiology (IAA/auxin is well-documented as the primary apical dominance hormone), but citing a plant physiology textbook reference would strengthen this claim.
First-year hazel regrowth of 1–2 m from coppiced stools. (non-blocking)
Consistent with practitioner experience and stated in the Coppice Woodland Management procedure node, but not given as an explicit measurement in CIT-VR-01. A specific forestry reference (e.g., Buckley 1992 ‘Ecology and Management of Coppice Woodlands’) would strengthen this.

Key passage: ‘Coppice stems grow from epicormic buds developed from groups of cells called bud precursors in the cambium under the bark on cut stem bases. Epicormic buds develop and grow when the upper parts of the stem (which normally produce inhibitory plant hormone analogues) are removed.’ Also explicitly corrects the misconception that coppice regrowth is from root suckers: ‘Note that the use of the term suckers above is incompatible with an accurate understanding of how coppice works.’ Source for: epicormic bud mechanism, cambium bud precursors, apical dominance inhibition, species-specific regeneration differences.
