<div>Context - Climate and land-use change have led to disturbance regimes in many ecosystems without a historical analog, leading to uncertainty about how species adapted to past conditions will respond to novel post-disturbance landscapes.</div>
<div><br>
</div>
<div>Objectives - We examined habitat selection by spotted owls in a post-fire landscape. We tested whether selection or avoidance of severely burned areas could be explained by patch size or configuration, and whether variation in selection among individuals
could be explained by differences in habitat availability.</div>

Nevada, California, USA, with individual owls occupying home ranges spanning a broad range of post-fire conditions after the 2014 King Fire.</div>

<div>Results<span style="font-family: "Trebuchet MS", Trebuchet, sans-serif; background-color: rgb(255, 255, 255); display: inline !important"><span> </span>-<span> </span></span>Individual spotted owls whose home ranges experienced less severe fire (< 5% of
home range severely burned) tended to select severely burned forest, but owls avoided severely burned forest when more of their home range was affected (~ 5–40%). Owls also tended to select severe fire patches that were smaller in size and more complex in
shape, and rarely traveled > 100-m into severe fire patches. Spotted owls avoided areas that had experienced post-fire salvage logging but the interpretation of this effect was nuanced. Owls also avoided areas that were classified as open and/or young forest
prior to the fire.</div>

<div>Conclusions<span style="font-family: "Trebuchet MS", Trebuchet, sans-serif; background-color: rgb(255, 255, 255); display: inline !important"><span> </span>-<span> </span></span>Our results support the hypothesis that spotted owls are adapted to historical
fire regimes characterized by small severe fire patches in this region. Shifts in disturbance regimes that produce novel landscape patterns characterized by large, homogeneous patches of high-severity fire may negatively affect this species.</div>
