The Cassin’s Finch (Haemorhous cassinii) is a small (16 cm [6 in]), stocky songbird of the western interior mountains from central British Columbia down into the Sierra Madres of Mexico. It is found in open coniferous forest, but during the winter and migration it can also be found in deciduous woodland and brushy habitats. It eats primarily seeds. The Cassin’s Finch will experience a high degree of climate exposure and has a moderately high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Moderately Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Highly Vulnerable under the RCP 8.5 Scenario. The Cassin’s Finch’s climate change vulnerability is impacted by factors related to movement, life history, and abiotic niche, which influence its ability to shift in space, persist in place, and respond to climate change impacts. It also has documented or modeled responses to climate change that impact its vulnerability score.

As appropriate to local site conditions (e.g., topography, prevailing winds, disturbance history, infrastructure) (Urza et al. 2023) and not in persistent piñon (Pinus spp.)-juniper (Juniperus spp.) woodlands (Romme et al. 2009, Darr et al. 2022), thin stands of trees in forests and woodlands to natural or historic densities that reduce the probability of insect and disease outbreaks and stand-replacing wildfires and promote the growth of native understory cover (Redmond et al. 2023). Avoid unnecessary removal of large old-growth trees and snags, which serve as important wildlife habitat (Kalies and Rosenstock 2013); leave some juvenile trees or plant seedlings to promote establishment of new trees (Redmond et al. 2023); use best practices to maintain soil health (e.g., Tomao et al. 2020) including retaining sufficient seed trees and sources of mycorrhizal inoculum (Simard et al. 2021) and limiting pile burning and mastication where possible (Ross et al. 2012); implement landscape- and regional-scale heterogeneity in treatment design (Bradley 2009); and evaluate treatment effectiveness (e.g., McKinney et al. 2022, Davis et al. 2024, Hood et al. 2024), including monitoring local SGCN populations. Potential collaborators: BLM, NPS, USFS, SFD, SLO, non-profit organizations.
Natural System Modifications
Assess the impacts of stream-flow magnitude, frequency, timing, duration, and rate of change on riparian ecosystems and the effects of hydrologic alterations on these ecosystems. Determine flows needed to sustain SGCN and their habitats and the effects of flow modification by upstream dams and of upland disturbances in local watersheds (Goeking and Tarboton 2022). Work with agencies that manage dams and reservoirs to ensure released environmental flows match amounts and timing of flow needed for persistence of native riparian communities and associated SGCN, including allowing for overbank flows to coincide with seed dispersal from native vegetation (e.g., Greco 2013) and when saturated soil can best benefit SGCN prey.

Assess the synergistic effects between climate change and other threats to SGCN and their habitats (e.g., Friggens et al. 2019, Parks et al. 2019).

Design and implement riparian and aquatic habitat restoration projects to benefit SGCN. This may include establishing priorities for habitat restoration and developing reach-specific plans. May also include designing and implementing low-tech, process-based restoration techniques (Wheaton et al. 2019) to restore degraded headwater stream systems and improve SGCN habitat or specific actions such as reintroducing keystone species including American beavers (Castor canadensis) (Baker and Cade 1995, McKinstry et al. 2001, Grudzinski et al. 2022) and restoration and monitoring of self-sustaining populations of North American river otters (Lontra canadensis) and native fishes.

Natural System Modifications
Determine amount, status, and trend of upland, aquatic, and riparian habitats; levels of fragmentation; and how SGCN might be affected. Identify appropriate locations and implement projects to enhance habitat quality and connectivity or prevent further fragmentation. This may include re-connecting streams and aquatic habitats that have been fragmented by dams, diversions, and other man-made structures that isolate and preclude movement of aquatic and semi-aquatic SGCN. Remove structures when feasible; otherwise, improve existing infrastructure by incorporating passage features for aquatic organisms (e.g., fish ladders). May also include protecting and promoting the natural establishment, development, and succession of native riparian vegetation by addressing any locally limiting hydrological conditions (e.g., ensuring overbank flooding occurs at optimal times and establishment of early successional vegetation) (Hatten et al. 2010, Greco 2013, Stanek et al. 2021, Wohner et al. 2021). May further include emphasizing restoration in areas that will enhance connectivity between native riparian habitat patches (e.g., migratory stopover sites) (McNeil et al. 2013).

Residential and Commercial Development
Determine distribution and habitat needs of SGCN that reside in (e.g., Boakes et al. 2024) or near urban areas. This includes initiation and promotion of citizen or community science activities that document SGCN and other wildlife in and around urban areas. Inform municipal staff of nearby SGCN and how to minimize development-related impacts to SGCN and their habitats. Encourage community or individual enrollment, as appropriate, in programs designed to benefit particular SGCN or taxa (e.g., Monarch City USA; https://www.monarchcityusa.com/) and in wildlife habitat certification programs (e.g., National Wildlife Federation; https://certifiedwildlifehabitat.nwf.org/; Albuquerque Backyard Refuge Program; https://friendsofvalledeoro.org/abq-backyard-refuge/).Potential collaborators: universities, municipalities, non-profit organizations, private landowners.

This includes solid waste that may entangle wildlife. Potential collaborators: EPA, NMDA, NMED, universities, local governments, municipalities, private industry.
Climate Change and Severe Weather
Determine how regional and global climate change will affect SGCN, vegetation patterns (e.g., Davis et al. 2019, Coop et al. 2020, Guiterman et al. 2022, Davis et al. 2023), and community (e.g., Rosenblad et al. 2023) and ecosystem processes and dynamics, including disturbance regimes. This includes identifying SGCN (e.g., Glick et al. 2011) and associated habitats that are most likely to be negatively affected by climate change, including impacts on travel corridors, habitat connectivity, and species and habitat ranges. Identification of environmental conditions or thresholds that could limit SGCN is especially important. Potential collaborators: BLM, NPS, USFS, USFWS, USGS, EMNRD, SLO, universities.

Climate Change and Severe Weather
Promote land-management practices, standards, and guidelines to conserve and/or restore structure and function of corridors that provide important habitat for SGCN and ability for animals to move as climate conditions change. This should include both mesic and xeric riparian communities that serve as important migratory corridors for birds and other wildlife while providing ecosystem services and wildlife corridors that link isolated mountain ranges (Powledge 2003) and coniferous forest patches. Potential collaborators: BLM, NPS, USFS, USFWS, SLO, universities, private landowners, Tribal natural-resource managers.
Natural System Modifications
Promote post-fire management activities that are beneficial to SGCN. Includes minimizing ash flow into streams and other post-fire impacts to water quality (Rhoades et al. 2019a, Rhoades et al. 2019b), augmenting natural plant regeneration (e.g., planting tree seedlings in areas with appropriate microclimatic conditions and re-seeding burned areas with native species and when there are appropriate climatic conditions) (Herron et al. 2013, Copeland et al. 2018, Marshall et al. 2023) and protecting natural seed sources (Stevens et al. 2021), and encouraging heterogeneity (Ziegler et al. 2017, Owen et al. 2020).

These include modifying barrier fences along roadways, constructing road crossings, placing warning signs for motorists, marking utility lines so they can be readily seen by birds, and placing safeguards that will reduce the probability of electrocution. Integrate benefits to SGCN in projects primarily designed and implemented to enhance safe passage for large mammals (e.g., projects implemented under the Wildlife Corridors Action Plan) (Cramer et al. 2022). Monitor the efficacy of mitigation measures and initiate any identified maintenance and improvements.
