The Cactus Wren (Campylorhynchus brunneicapillus couesi) is a medium-sized songbird (18-22 cm [7-9 in] long; 32-47 g [1-2 oz]) with a brown back, whitish underparts with a brown streak, and a bold white line above the eye. It forages for spiders, insects, and cactus fruits in desert-cactus and other shrub habitats. It occurs in the desert southwestern US and south into Mexico. The Cactus Wren will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Cactus Wren’s climate change vulnerability is impacted by factors related to movement and life history, which influence its ability to shift in space and persist in place.

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.

Invasive and Other Problematic Species, Genes, and Diseases
As needed, gather additional information regarding the distribution of tamarisk (Tamarix spp.) and other exotic plants in riparian habitats (e.g., NHNM 2023). Determine the impact of exotic plants, and their removal and reduction, on SGCN and their habitats. Create and implement site-specific plans, with measurable goals and objectives, to restore the historic structure and composition of riparian habitats while minimizing negative impacts on SGCN and soil health (Wagner 2023). Prioritize removal of monoculture stands of non-native plants (e.g., Johnson et al. 2018) and ensure that sufficient native riparian vegetation is locally available to SGCN and that local hydrological conditions support native vegetation regrowth. Since pollinating insects may use exotic riparian plants (e.g., Pendleton et al. 2011), minimize impacts of removing these plants on pollinating insect SGCN, including by avoiding herbicide application when plants are in bloom and treating the focal area in stages. Include post-implementation monitoring and maintenance for all riparian restoration projects. Document and report restoration approaches used, including successes and failures (Shafroth et al. 2008, Sogge et al. 2013).

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.

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).
