“…Nevertheless, fire treatments were applied during the dormant seasons, when the metabolic demands are low, and thus, the NSC levels are high. In fact, the same study found that basal clipping during summer (as a surrogate of growing season fires) did produce a fast decrease in the root starch concentration of C. orbicularis [73]. The second exception was reported for the shrub Ceanothus spinosus, for which no differences in the lignotuber starch concentration were found between resprouting and control plants during a severe drought episode [35] (Table 3).…”

“…Therefore, this review considers a total of eight studies (references 69 and 70, and those included in Table 3). Root NSC concentrations after clipping or burning were significantly reduced in three of the five species evaluated for fire effects (plants resprouting after fire vs. undisturbed plants) [35,72] and in the six species evaluated for basal clipping effects (compared to unclipped plants) [18,33,34,73]. In all cases, the percentage of plants recovering after the removal of most the aboveground biomass (i.e., resprouting capacity) was always higher to c. 60% (Table 3).…”

“…However, some exceptions were detected (Table 3). The first one was Celastrus orbicularis, a liana for which fires did not affected the NSC root concentrations compared to unburnt plants [73]. Nevertheless, fire treatments were applied during the dormant seasons, when the metabolic demands are low, and thus, the NSC levels are high.…”

Purpose of Review Nonstructural carbohydrates (NSC) promote tree survival when photosynthesis is impeded by factors whose impact is expected to increase under climate change, like droughts, herbivory, and fires. Nonetheless, it remains unclear whether NSC are depleted under natural conditions and if they mediate tree recovery. To determine if there is a general pattern of NSC variation, we reviewed the recent (2008–2018) literature reporting NSC changes in response to droughts, insect herbivory, and fires, in woody species under natural conditions. Recent Findings We found 25 cases in 16 studies examining NSC dynamics post-drought, most of them conducted in species of Pinaceae or Fagaceae in Mediterranean Europe. Drought-affected trees had lower NSC, starch, and sugars concentrations than unaffected counterparts, although these results were entirely driven by roots and trunks of Pinaceae. We found only six studies examining NSC responses to herbivory, which indicate both increases and decreases in NSC concentrations inconsistently related to changes in growth or survival. Fire led to consistent decreases in NSC that mediated a successfully regrowth in absence of drought. Summary NSC decrease related equivocally to the occurrence of drought, fire, and herbivory and also to post-disturbance recovery, indicating no clear pattern of decreasing forest resilience under current climate change. An exception seems to be Pinaceae, which showed decreased NSC and performance in response to drought or herbivory. We suggest that a more water conservative strategy and smaller NSC pools in gymnosperms relative to angiosperms underlie these results.

“…C. orbiculatus may facilitate the growth of other destructive vines in forests (Fike & Niering, 1999). C. orbiculatus responds positively to fire via root suckering, adding potential fuel to forest systems (Pavlovic et al, 2016). C. orbiculatus can have negative impacts on tree regeneration, which may impact the course of succession in a forest system (Ellsworth et al, 2004).…”

Celastrus orbiculatus is native to China. It is also recorded as native in the Korean Peninsula, Japan and the Russian Far East and Sakhalin Island.C. orbiculatus has been introduced into the EPPO region, and New Zealand and North America. USDA (2020) record C. orbiculatus as present in 25 eastern states. However, 31 states document C. orbiculatus as present in at least one county according to EDDMapS (https://www. eddma ps.org/). The current distribution of the species in the United States extends from Maine south to Georgia and west to Iowa (IPSAWG, 2019). Patterson (1973) stated that C. orbiculatus had spread to 33 US states, which included California and Washington. POWO (2020) confirmed that the species is present in Washington State. C. orbiculatus is also present in Canada in New Brunswick, Ontario, and Quebec (USDA, 2020) and Nova Scotia (CABI, 2021). C. orbiculatus was first introduced into New Zealand as a garden ornamental in 1905. Williams and Timmins (2003) state that C. orbiculatus has a localized distribution in New Zealand but it is widely distributed in the northern areas of the North Island. Beringen et al., (2017) report that C. orbiculatus is present in eight EU countries (Austria, Belgium, the Czech Republic, Germany, the Netherlands, Poland, Sweden, and the United Kingdom) and Gudžinskas et al. (2020) record the species in 13 European countries (adding Latvia, Lithuania, Norway, European Russia, and Ukraine to the previous list) (see EPPO, 2021a). | MOR PHOLOGY | Plant typeDeciduous woody vine (the form can vary between vine and shrub). | DescriptionBoth Chinese and North American morphological descriptions have been given as the species could be imported from both regions.
