“…ing similar to another study in the Blue Mountain Ecoregion approximately 30 km to the north (Progar et al 2017). The nearly 150 % increase we documented for 1000 hr fuels in the fall 5 yr reburn treatment between reburns one and two is due to the higher mortality in the initial fall burns.…”

“…We expected fall 5 yr reburning to continue to consume more fuel than spring reburning as found by others in initial burns (Knapp et al 2005, Fettig et al 2010, Progar et al 2017. However, consumption of woody and forest floor fuels with repeated 5 yr burning was consistently low, and there was a lack of persistent seasonal consumption differences.…”

Prescribed fire is widely applied in western US forests to limit future fire severity by reducing tree density, fuels, and excessive seedlings. Repeated prescribed burning attempts to simulate historical fire regimes in frequent-fire forests, yet there is limited long-term information regarding optimal burn season and frequency. In addition, burns are operationally feasible only in the spring and late fall, largely outside the historical wildfire season. This study quantifies the effect of seasonal reburns on woody surface fuels, forest floor fuels, and understory tree regeneration abundance in six previously thinned ponderosa pine (Pinus ponderosa Lawson & C. Lawson) stands in the southern Blue Mountain Ecoregion of Oregon, USA. Each stand consisted of an unburned control, and four season by reburn treatments: spring 5 yr, spring 15 yr, fall 5 yr, and fall 15 yr. We evaluated season and frequency of reburn for woody surface fuel (1 hr to 1000 hr), forest floor fuel (litter and duff, undifferentiated), and understory conifer seedling density (regeneration). Burning was initiated in the fall of 1997 and spring of 1998; we present results in this pa-RESUMEN

“…In ponderosa pine forests the litter layer accounts for ~60% of fuel loading typically targeted for removal with prescribed fire ( Progar et al, 2017 ; Urbanski et al, 2018 ). The EFs we have measured for needles (the primary component of ponderosa pine litter layers), needles + FWD, and needles + cones can be used to improve prescribed fire emission estimates in smoke management tools such as First Order Fire Effects Model (FOFEM; Lutes, 2019 ).…”

“…Furthermore, a greater level of damage to fine roots (abundant during this period) can be expected [72,119]. However, fuels are usually described as typically drier later on in the year [120], i.e., during the typical burning season (autumn), which may imply higher mortality rates [114,121,122]. However, other factors such as the activity of insect pests, the climatic conditions following the fire and tree species susceptibility can interact and lead to a complex response [123] and inconclusive results, probably because fire effects often outweigh the effects of other factors [124].…”

“…In this respect, the temperature at a specific location within a tree will be influenced by the distribution of temperature over the whole bark surface, which is very irregular under fire conditions [55,152]. Only local conditions at the tree level (e.g., the natural accumulation of branches fallen around the tree or lichens growing along the stem) can generate burn intensities that will potentially cause this type of damage [121]. This has already been observed in previous field studies investigating the effect of PB on cambium [13].…”

Little is known about the interactions between the variables involved in the post-fire response of Mediterranean pine species to prescribed burning (PB). Thus, it is essential to develop an empirical model in order to assess the influence of tree and stand attributes, burn season, and fire severity on the probability of stem cambium damage occurring. Prescribed burnings were conducted in different seasons and areas covering a wide climatic and ecological range. Potential explanatory variables were measured. A random effects hurdle model framework was used to evaluate the temperature duration above 60 °C as a proxy for stem cambium damage at tree scale. The results showed significant differences in cambium damage between the PB seasons. Pinus nigra was more resistant than other pine species. Bark thickness was critical for protecting cambium. Volume of crown scorch, percentage of stem scorch, and maximum outer bark temperature were directly related to temperature duration above 60 °C in the cambium. Prescribed burning conducted under tree canopy in Mediterranean pine species generally results in a low level of cambium damage. Empirical models could help managers to predict the effects of PB and thus select the most suitable prescriptions.
