Taller trees are protected from heating in aerial buds via attainment of escape height Higgins et al.

Additionally, increased diameter generally indicates greater bark thickness, which can offer protection from lethal heating to the underlying cambium van Mantgem and Schwartz ; Clarke et al. It is also possible that, due to their increased carbohydrate reserves, mature oak trees have greater capacity to replace damaged tissues Malanson and Trabaud ; Niemiec et al.

Similar correlations between tree size and crown injury have been documented in other prescribed fire studies Ryan and Reinhardt ; Kobziar et al.

Scorching, our strongest predictor of crown injury, has been found to increase the probability of mortality in studies of conifer species Ryan and Reinhardt ; Kobziar et al. Oregon white oak tolerance to crown scorching is commonly assumed to be high, but few studies have established this with certainty. Several authors have examined prescribed fire effects on Oregon white oak regeneration Tveten and Fonda ; Regan and Agee , and one of these measured crown scorch in trees Regan and Agee , but did not attempt to relate this effect to oak injury.

Peter et al. Thus, visible scorching of leaves in the crown may not indicate subsequent bud death with any certainty as in Peter et al. If this is the case, it might explain the highly variable dieback response at higher levels of crown scorching that we observed Fig.

If scorching in oak crowns does not have a direct relationship with bud mortality, it may be of limited value as a field assessment of post-fire injury in highly fire-resistant species such as Oregon white oak. While we were unable to precisely predict post-fire oak crown injury based on effects of understory burns, there were some clear thresholds of tree response.

These results imply the existence of a high tolerance of Oregon white oaks to fire-induced injury, only beyond which will a response be observable in impacted trees.

It appears that substantial injury must occur before imbalances are created in the hormones that regulate plant growth such that a sprouting response is provoked in adventitious buds Anderson et al. Correspondingly, bud death is also unlikely unless a tree is subjected to heat sufficient to scorch the entire crown. The connection between basal duff consumption and oak vigor is less clear. One potential consequence of duff consumption for oak vigor is injury to fine roots due to heating as duff smolders following the passage of a flame front Swezy and Agee ; Varner et al.

Despite a number of trees experiencing considerable proportional duff consumption, we found no apparent negative impacts on oak vigor within two years of prescribed burns. Similarly, while Kobziar and others Kobziar et al. It is possible, however, that negative effects of duff consumption may be revealed over a longer time period than that covered by either our study or Kobziar et al. Injury to fine roots, and the resulting reduction in water absorption and holding capacity, may only be detrimental if trees are severely drought-stressed prior to burning, which was likely not the case in this study, or following burning, which has yet to be observed.

Another possible reason for this null result is that few fine roots were located in or close to the duff layer around the bases of studied trees. While Oregon white oak is generally considered to be a deep-rooted species with a long tap root, Devine and Harrington found that, in the coarse-textured glacial outwash soils of JBLM, the majority of fine lateral roots were located within the top 40 cm of the mineral soil profile. We did not examine fine oak roots embedded in duff prior to burns; the quantity of fine roots underlying duff in the surficial mineral soil, and the amount of heating that occurred at these depths during burns, is not known.

While our results indicated that, as in other systems, duff consumption in Oregon white oak woodlands was greater with deeper duff depths Frandsen ; Hungerford et al. Post-fire bud burst is a commonly observed but little understood phenomenon in Oregon white oaks. Similar to our observations, other researchers have documented a late-season flush of crown foliage following burns in Oregon white oaks Peter et al.

When injured, oaks are capable of sprouting both from the crown and base of the tree Fry ; Gucker While post-fire sprouting is a common mechanism for regeneration following disturbance, this additional expenditure of carbohydrates at the end of the growing season may diminish reserves available for crown repair in the spring following low-intensity surface fire, and thus reduce spring leaf production. Conversely, there might be a net gain for the tree if these new leaves are able to generate excess carbohydrates, which may be readily available the following spring.

We did not observe an effect, either positive or negative, of late-season foliage production on oak vigor within two seasons of the prescribed burns in this study. To our knowledge, this phenomenon has been little studied, and the impact of fall bud burst on oak vigor and spring leafing response is unknown. Similarly, we were unable to find studies documenting or attempting to explain the delayed crown recovery that we observed two years following burns in a few previously leafless trees.

It is possible that the epicormic growth that occurred took some time to develop due to resprouting tissues having to penetrate thick branch bark D.

Epicormic resprouting from the crown is common in angiosperms, but bud primordia may be located more deeply underneath bark in some species compared to others Clarke et al. It is likely that meristematic tissues are deeply buried in Oregon white oak bark, in order to confer greater protection from heating in the canopy van Mantgem and Schwartz ; Bond ; Burrows et al.

The results of mortality modeling using the FOFEM program deviated substantially from our observed results, with predicted mortality an order of magnitude greater than observed topkill Table 4. As the algorithm used in this model is not based on data from Oregon white oak mortality studies, but instead a general, non-species-specific equation derived from studies of conifer fire response, this is not an unexpected finding Ryan and Amman ; Keane and Lutes The magnitude of the prediction error, however, is considerable, and demonstrates the need for more accurate fire effects models for use in oak-dominated ecosystems.

Of particular note are the variables upon which the FOFEM model relies in order to predict mortality—in the case of Q. Both of these metrics present issues for the modeling of mortality, and may constitute large sources of error, leading to the significant departure from our observations in the field.

The fire effects model documentation indicates that the relationship between DBH and bark thickness is assumed to be linear: while a common simplification, this is rarely the case, and has not been established for Oregon white oak Jackson et al.

Other studies have found that these models can underpredict bark thickness, potentially leading to overestimation of mortality in fires Zeibig-Kichas et al. Moreover, FOFEM employs a common bark thickness coefficient for all oak species, an assumption that likely adds considerable error to the model. Issues with the poor predictive ability of crown scorch for oak topkill, outlined above, likely contributed to the overprediction of mortality by using an algorithm that relies on a strong correlation between these two variables.

The inaccuracy of the Ryan-Amman model when applied to oaks has been documented in other studies, and, while our data indicate that predicting mortality, or even topkill, is difficult for this species, incorporating a species-specific model into the FOFEM program would nevertheless greatly improve its predictive ability Hood et al.

Their high level of resistance and resilience to fire, coupled with great variability in post-fire response, make Oregon white oak mortality and topkill prediction challenging. This is particularly the case in short-duration studies such as this one, as the manifestation of post-fire tree injury is often delayed Ryan and Reinhardt ; Agee However, Oregon white oak mortality is uncommon following understory burns Thysell and Carey ; Regan and Agee , indicating that, while substantial injury to mature Oregon white oaks is possible, the risk of mortality is quite low.

Our results hint at the existence of other factors such as tree age or pre-burn vigor , unmeasured in this study, that may influence outcomes for oaks in restoration fires.

Additional studies, including long-term monitoring, may clarify the relationship between fire effects and oak injury in prescribed burns.

While many studies have been conducted in long-unburned conifer-dominated systems Hood et al. While this research is intended to be followed by long-term monitoring of studied stands, the preliminary results presented here may help to guide management decisions in the near future. The remarkable resilience of fire-excluded Oregon white oak demonstrated in this study indicates that extraordinary precaution on the part of managers reintroducing fire into these systems may not be warranted; however, continued monitoring to evaluate longer-term impacts, as well as impacts from more burns under a greater range of conditions, will be necessary to establish this with more certainty.
