Determine the pre-suppression fire return interval, fire intensity, and historic stand structure and composition of riparian forests in white fir, mixed-conifer and Jeffrey pine forests of the Tahoe Basin and using reconstruction information and Fuels Management Analyst software, work with managers to develop targets for surface and ladder fuels by size class for different riparian forests.

Threshold Categories
-
Recent studies and new fuel treatment methods suggest riparian forests can be effectively treated if guidelines are developed through research and in collaboration with managers who understand treatment constraints.

| 07/27/2017 4:10 PM | System | Objectives: To determine whether adjacent coniferous riparian and upland forests burned historically with different frequencies and seasonalities, and whether these relationships varied by forest, site, and stream characteristics. |
||
| 07/27/2017 4:09 PM | System | Findings: • Riparian fire return intervals (FRI) ranged from 8.4 to 42.3 years under a liberal filter (mean 16.6), and 10.0 to 86.5 years under a conservative filter (mean 30.0). • Upland FRI ranged from 6.1 to 58.0 years under a liberal filter (mean 16.9), and 10.0 to 56.3 years under a conservative filter (mean 27.8). • Riparian and upland fire return intervals were significantly different in only one quarter of the sites we sampled. • Riparian and upland areas did not burn with different seasonalities, and fire events occurred primarily during the late summer-early fall dormant season in both riparian and upland areas (88% and 79% of scars, respectively). • FRI was shorter in forests with a higher proportion (>22.7–37.6%) of fire-tolerant pine (Pinus spp.), sites east of the Sierra crest, lower elevation sites (<1944 m), and riparian zones bordering narrower, more incised streams (width/depth ratio <6.2). • Upland areas exhibited a greater degree of fire–climate synchrony than riparian areas. |
||
| 07/27/2017 4:08 PM | System | Management Implications: • Our study suggests that coniferous riparian forests in the Sierra Nevada historically experienced frequent fire, often at intervals not significantly different from the adjacent upland forests. This relationship, however, does vary as a function of forest, site, stream and climate conditions. Managers should take into account local conditions when developing treatment prescriptions for riparian areas, considering how forest, site and stream characteristics would have likely influenced fire return intervals and subsequent fire effects. • Riparian areas surrounded by forests with a high proportion of fire-tolerant pine species (about one-third of the basal area or greater), especially those east of the Sierra crest, likely experienced more frequent fire than riparian areas in other forest types, and could be treated similarly to upland areas. Less intensive treatment, such as hand thinning and pile burning small trees, should be considered for riparian areas in other forest types. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional management implications. |
