Data:<\/SPAN><\/SPAN> <\/SPAN><\/SPAN>Gridded coverages based on PRISM climate data were used to calculate departure of mean temperature in winter (Dec. \u2013 Feb.), spring (Mar. \u2013 May), summer (Jun. \u2013 Aug.), and fall (Sep. \u2013 Nov.) for the recent 5-year period as compared with previous years in the historical record. Data were summarized at the Subsection scale of the USFS National Hierarchy of Ecological Units and applied to the corresponding landscape (LTA). There is a one-year lag between the most recent available PRISM data and the TCA Assessment year, for example, the 2024 TCA Assessment used 2019-2023 data for the most recent time period, and 1900-2018 data for the historical baseline.<\/SPAN><\/SPAN><\/P>
