A model comparison of fire return interval impacts on carbon and species dynamics in a southeastern U.S. pineland [PDF]

Ecosphere, 2021
Ecosystem process models can be used to predict forest response to disturbances at a range of scales. Selection of the spatial class of model should depend on the scale of the research or management question, and model type should depend on the ecosystem

Fire Return Interval and Season of Fire Alter Bud Banks

Rangeland Ecology & Management, 2019
Despite the importance of vegetative reproduction in annual tiller replacement, little is known about the patterns and timing of tiller recruitment from the bud bank, especially regarding fire return intervals and seasons of fire. We examined aboveground

Fire return intervals and recruitment affect population growth rate of canopy trees in tall open forest in humid savanna

Ecosphere
Savannas are the major biome in tropical regions of the globe, defined as sparsely wooded regions with a continuous herbaceous layer of mainly C4 grasses where rainfall is distinctly seasonal. Fire is a common feature of most savannas.

Long‐Term Dynamics of the Geophyte Toxicoscordion fremontii (Torr.) Rydb. Across Two Wildfires: Fire‐Return Interval Implications

Ecology and Evolution
In Mediterranean‐climate shrublands, fire‐return intervals are decreasing, leading to negative impacts on native communities. Most research on this topic has been conducted on woody species, while little is known about the impacts of increased fire ...

Larch forests of Middle Siberia: long-term trends in fire return intervals [PDF]

Regional Environmental Change, 2016
Fire history within the northern larch forests of Central Siberia was studied (65+°N). Fires within this area are predominantly caused by lightning strikes rather than human activity. Mean fire return intervals (FRI) were found to be 112 ± 49 years (based on fire scars) and 106 ± 36 years (based on fire scars and tree natality dates).

Late Pleistocene montane forest fire return interval estimates from Mount Kenya

Journal of Quaternary Science, 2022
AbstractPast forest fire events and fire frequencies are reconstructed with sediment–charcoal records at lake catchment spatial scales. Few quantitative palaeofire analyses exist in tropical montane forests, where fire return intervals are long (decadal and centennial scales) because of the infrequency of fire weather and fuel conditions.

Using Fire History Data to Map Temporal Sequences of Fire Return Intervals and Seasons

Fire Ecology, 2010
Analysis of complex spatio-temporal fire data is an important tool to assist the management and study of fire regimes. For fire ecologists, a useful visual aid to identify contrasting fire regimes is to map temporal sequences of data such as fire return intervals, seasons, and types (planned versus unplanned fire) across the landscape. However, most of

Reconsidering the fire ecology of the iconic American chestnut

Ecosphere, 2020
The iconic American chestnut (Castanea dentata) once spanned a large portion of eastern North America before its functional extinction in the early 20th century due primarily to non‐native fungal pathogens.

Fire disturbance influences endangered Cape Sable Seaside Sparrow (Ammospiza maritima mirabilis) relative bird count

Conservation Science and Practice, 2019
Periodicity of fire disturbance is a known driver of ecosystem function and is reported as important in both promoting and maintaining viable breeding habitat for the endangered Cape Sable Seaside Sparrow (Ammospiza maritima mirabilis; CSSS).

Effects of a short fire‐return interval on resources and assemblage structure of birds in a tropical savanna [PDF]

Austral Ecology, 2011
AbstractFire frequency is a key land management issue, particularly in tropical savannas where fire is widely used and fire recurrence times are often short. We used an extended Before‐After‐Control‐Impact design to examine the impacts of repeated wet‐season burning for weed control on bird assemblages in a tropical savanna in north Queensland ...
