Notes: The DNR Planning Area boundary does not include the full extent of the proposed USFS South Fork Tieton Project Area. The potential treatments shown in this dashboard are a preliminary draft that will change with the ongoing planning process. The total potential treatment areas are summarized only within USFS non-wilderness area of the DNR Planning Area boundary.
This is a dashboard to visualize potential forest health and fuel reduction treatments with geospatial data from a landscape evaluation conducted by the Washington Department of Natural Resources (DNR). Users may need to adjust browser zoom to see the information in all panels. This dashboard was created for the Tieton Planning Area on the Okanogan-Wenatchee National Forest (OWNF). The landscape evaluation is available online: https://www.dnr.wa.gov/sites/default/files/publications/rp_2020_le_tieton.pdf. Note that the DNR planning area boundary is not identical to the OWNF project area boundary. Also, the maps and figures are focused on non-wilderness USFS land in the planning area.
Treatment targets are based on the departure of current forest structure from historical and future ranges of variability at the sub-watershed scale across all land ownerships. The Tieton planning area has a mixture of dry, moist, and cold forests, and potential treatments are well below the target range in both dense and open dry forests (See Departed Structure and Treatment Targets tab).
Landscape Treatment Priority (LTP) is based on fire risk, drought vulnerability, departed structure, and wildfire transmission to homes. The Tieton planning area has a relatively high distribution of LTP, and potential treatments occur in a similar distribution to the available area (See Landscape Treatment Priority tab).
Large Dense Forest Sustainability (LDFS) is based on fire risk, drought vulnerability, and current forest structure. The Tieton planning area has a relatively low distribution of LDFS, and potential treatments occur in a similar distribution to the available area but are concentrated at the lower end of the distribution in late-successional reserves (LSR - See Large Dense Forest Sustainability tab).
