“…Johnson and Young (1992) observed a similar association between decline in ring width of Pinus taeda and occurrence of hurricanes and nor'easters on the Delmarva barrier islands. Samuelson et al (2013) and Robichaud and Bégin (1997) also reported a similar 3 to 4 year growth decline in ring width following storm events.…”

The Mid‐Atlantic coastal forests in Virginia are stressed by episodic disturbance from hurricanes and nor'easters. Using annual tree ring data, we adopt a dendroclimatic and statistical modeling approach to understand the response and resilience of a coastal pine forest to extreme storm events, over the past few decades. Results indicate that radial growth of trees in the study area is influenced by age, regional climate trends, and individual tree effects but dominated periodically by growth disturbance due to storms. We evaluated seven local extreme storm events to understand the effect of nor'easters and hurricanes on radial growth. A general decline in radial growth was observed in the year of the extreme storm and 3 years following it, after which the radial growth started recovering. The decline in radial growth showed a statistically significant correlation with the magnitude of the extreme storm (storm surge height and wind speed). This study contributes to understanding declining tree growth response and resilience of coastal forests to past disturbances. Given the potential increase in hurricanes and storm surge severity in the region, this can help predict vegetation response patterns to similar disturbances in the future.

“…from the other southern pine species (Eberhardt et al 2011). An anomaly to the aforementioned abrupt SG transitions between years has been reported for loblolly pine (Pinus taeda L.) grown outside its native range in the milder climate of Hawaii (Samuelson et al 2013). The observed gradual decrease in SG through the latewood-earlywood transition, particularly evident in the juvenile wood zone, could have resulted from growth throughout the year given milder climate conditions not found on the mainland (Harms et al 2000;Samuelson et al 2010Samuelson et al , 2013.…”

“…The most common application for X-ray densitometry is the collection of wood quality data (ring SG, latewood percent, etc.) which have been used to determine the transition age from juvenile wood to mature wood (Koubaa et al 2005;Clark et al 2006;Gapare et al 2006;Mora et al 2007;Guller et al 2012) as well as differences imparted by site quality (Adamopoulos et al 2009) and physiographic region (Tasissa and Burkhart 1998;Clark et al 2006;Jordan et al 2008;Samuelson et al 2013). For the benefit of foresters and ecologists, determination of the SG of a wood core taken from bark to pith can be weighted to give a value for SG reflecting that for a tree (Williamson and Wiemann 2010).…”

X-ray densitometry is a technique often used in tree growth and wood quality studies to incrementally measure density (specific gravity) along a radial strip of wood. Protocols for this technique vary between laboratories because of differences in species, equipment, tree age, and other factors. Here, the application of X-ray densitometry is discussed in terms of a case study specific to the southern pines, whereby loblolly (Pinus taeda L), longleaf (Pinus palustris Mill.), and slash (Pinus elliottii Engelm.) pine wood cores were analyzed using an automated system. Objectives of this study included an assessment of the potential impacts on wholecore wood quality data from wood core extraction and use of two different demarcation methods (threshold and inflection point) for the earlywood-latewood transition. Wood core extraction before X-ray densitometry showed minimal impact on the shapes of individual ring profiles, and whole-core wood quality data were essentially unchanged. An assessment of the inflection point method employed for determining the earlywood-latewood transition point in the X-ray densitometry data demonstrated that the growth ring profiles for the southern pines are not amenable to polynomial fitting. Indeed, in the southern pines, the earlywood-latewood transitions are as equally abrupt as the latewood-earlywood transitions. Accordingly, a threshold density deemed appropriate to define the onset of a growth ring would be equally appropriate to define the onset of latewood formation.

“…In addition, plots symptomatic for SPD had significantly greater fire damage than asymptomatic sites (48.5% compared to 10.5%; Eckhardt et al, 2007). While increased tree age and reduced radial growth have been associated with the presence of the Leptographium complex (Eckhardt et al, 2007), pine growth rates decline in older stands due to hydraulic limitation and declining respiration (Drake et al, 2010(Drake et al, , 2011 even when site conditions are good (Samuelson et al, 2013). In short, a low level of annual mortality is to be expected in pine stands regardless of age, and due to many causes, especially competition between trees.…”
