A survey of 104 old-growth stumps on the Redwood Experimental Forest, in northern California showed that (a) probability of a stump sprouting varied inversely with its diameter; (b) number of sprouts per sprouting stump and height of tallest sprout were not related to stump diameter; (c) lower portions of stumps sprouted more often and produced ...

2011年2月28日 · Redwoods don’t just sprout from stumps; they can also sprout new growth from their roots. Redwood roots extend horizontally under the soil. Many redwoods live in flood-prone ecosystems, on the banks of rivers. When redwood forests become flooded, sediment piles up on the surface of the soil, burying the roots a bit deeper than they were before.

2017年4月27日 · After disturbance or harvest, healthy redwood stumps sprout vigorously, often producing dozens of sprouts within two years of disturbance. These sprouts form highly aggregated spatial patterns because they are clustered around …

2022年2月10日 · We used annual re-measurement data from a replicated manipulative experiment in coastal northern California to determine how understory light, stand density, and spatial arrangement of residual trees affected coast redwood (Sequoia sempervirens) and tanoak (Notholithocarpus den-siflorus) stump sprouts regenerating after partial harvest of conife...

2022年7月1日 · Residual stand influenced stump sprout regeneration dynamics in multiaged redwood. Partial cutting initiated new cohort dominated by redwood and tanoak sprouts. Re-sprouting redwood outperformed re-sprouting tanoak to six years of age. Redwood sprouts became dependent on understory light in third growing season.

2020年11月16日 · After a regeneration harvest, any redwood that regenerates naturally is usually of stump sprout origin (Olson et al. 1990). When insufficient redwood stumps are present for regeneration, enrichment planting of nursery stock is a widely practiced option (O’Hara et …

After disturbance or harvest, healthy redwood stumps sprout vigorously, often producing dozens of sprouts within two years of disturbance. These sprouts form highly aggregated spatial patterns because they are clustered around stumps that may number less than 50 ha 1.

2009年12月25日 · Coast redwood [Sequoia sempervirens (D. Don) Endl.] is relatively unique among coniferous species because of its ability to produce stump sprouts after cutting. These sprouts are an important source of regeneration for this species because redwood typically does not reproduce reliably from seed (Olsen et al. 1990).

2007年6月15日 · In redwood, viable stump reproduction or planting is needed because of uncertainties with seedling regeneration. With redwood, sprouts are the easiest and fastest growing form of regeneration. Maintaining viable stump sprouting is therefore critical to the success of some multiaged silviculture systems.
