The culmination of these changes produced forests that are vulnerable to catastrophic change by wildfire, drought, and bark beetles, with climate change exacerbating this vulnerability. Management options available to address this problem include mechanical treatments (Mech), prescribed fire (Fire), or combinations of these treatments (Mech + Fire).&nbsp; All three active treatments (Fire, Mech, Mech + Fire) produced forest conditions that were much more resistant to wildfire than the untreated control and Mech + Fire improved&nbsp;forest resilience the most. There are multiple pathways for achieving success in Sierra Nevada mixed&nbsp;conifer forests.<\/p><\/div><div>\n<a class=\"uwspbtn uwsp-btn-solid-purple\" href=\"https:\/\/youtu.be\/eqm5aMY_UzQ%20\" target=\"_blank\">Watch Now  <i class=\"fa-solid fa-circle-chevron-right\"><\/i><\/a>\n<\/div><\/div><div class=\"hcard-mediacell\"><div class=\"iframe-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/eqm5aMY_UzQ \" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div><\/div><\/div><\/div>\n<\/div><div class=\"hslider-buttoncontainer\"><button class=\"hsliderBack horizontal-sliderbutton\" aria-label=\"previous slide\">\u276e<\/button><div class=\"single-card-nav\"><\/div><button class=\"hsliderForward horizontal-sliderbutton\" aria-label=\"next slide\">\u276f<\/button><\/div><\/section><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left\">PRESENTER<\/h2>\n\n\n\n<div style=\"height:32px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.uwsp.edu\/wp-content\/uploads\/2025\/12\/WFC_Rx-Fire_Scott-Stephens-scaled.jpg\" alt=\"\" class=\"wp-image-221642\" style=\"width:250px\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80%\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\">Scott L.
