The Least Shrew (Cryptotis parvus) is a small (10 cm [4 in] long) shrew that is widely distributed from the eastern US west to Colorado and New Mexico and from southeastern Ontario, Canada to the southernmost US. In New Mexico, it is found primarily in mesic areas with dense grass cover. The irrigation of the Great Plains has facilitated the extension of its distribution westward in the past few decades. The Least Shrew 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 the Representative Concentration Pathway (RCP) 4.5 Scenario and Moderately Vulnerable under the RCP 8.5 Scenario. The Least Shrew’s climate change vulnerability is impacted by factors related to demography and abiotic niche, which influence its ability to persist in place and respond to climate change impacts. It is also impacted by barriers, land-use changes, and other anthropogenic and biologic factors that could increase the effects of climate change.

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.

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.

BLM, USFS, SLO, private landowners, Tribal natural-resource managers.
Agriculture and Aquaculture
Promote grazing systems that incorporate rested pastures and help improve overall range condition and enhance wildlife habitat health and function. In upland areas, these systems may include rest-rotation and/or deferred-rotation. In riparian areas, beneficial grazing practices may also include grazing in early spring and restricting summer grazing and redistribution practices such as herding and developing drinking water sources in upland areas. Especially during times of drought, rested pastures can provide forage reserves and relieve pressure on grazed pastures or allotments. Potential collaborators: BLM, NRCS, USFS, USFWS, SLO, private landowners, Tribal natural-resource managers.
