Introduction Large-scale investments in restoring California’s forested watersheds are imperative for conserving biodiversity, enhancing water quality, and mitigating the future impacts of climate change. This study explores underlying incentives, major challenges, potential strategies associated with such investments. Methods An online survey was administered to 43 experts field gather their insights on forest watershed restoration The collected responses were then analyzed using a combination confirmatory factor analysis regression elucidate patterns relationships. Results revealed that key environmental outcomes, as reducing wildfire risks protecting supplies, principal motivators driving investment. At same time, significant barriers emerged, including high costs, limited workforce capacity, insufficient trust among stakeholders. also identified series effective overcome these obstacles, repositioning an infrastructure investment clearly demonstrating its ecological, social, economic benefits. Discussion Overall, findings underscore need more flexible funding frameworks, enhanced stakeholder engagement, improved data infrastructures. By addressing elements, policymakers practitioners can pave way resilient sustainable forested-watershed ecosystems California.

Abstract Forest thinning and prescribed fire are expected to improve the climate resilience water security of forests in western U.S., but few studies have directly modeled hydrological effects multi‐decadal landscape‐scale forest disturbance. By updating a distributed process‐based model (DHSVM) with vegetation maps from ecosystem (LANDIS‐II), we simulate resource impacts management scenarios targeting partial or full restoration pre‐colonial disturbance return interval central Sierra Nevada mountains. In fully restored regime that includes fire, thinning, insect mortality, reservoir inflow increases by 4%–9% total 8%–14% dry years. At sub‐watershed scales (10–100 km 2 ), dense can increase streamflow >20% thinner forest, increased understory transpiration compensates for decreased overstory transpiration. Consequentially, 73% gains attributable rain snow interception loss. Thinner headwater peak flows, reservoir‐scale flows almost exclusively influenced climate. Uncertainty future precipitation causes high uncertainty yield, additional yield is about five times less sensitive annual uncertainty. This decoupling response makes especially valuable supply during Our study confidence benefits restoring historic frequencies mountains, our modeling framework widely applicable other forested mountain landscapes.
