2022 Southwestern Willow Flycatcher

An ArcGIS Online (AGOL) page containing historical and predictive maps developed by James Hatten of the USGS for the southwestern willow flycatcher habitat across the southwestern United States. The model predicts the probabilities for suitable habitat for SWFL and can be used to guide restoration efforts.

Colorado Parks & Wildlife - Wildlife Species Profiles & Habitat Scorecards

The purpose of these profiles is to provide landowners and land managers with easy-to-use guidelines for understanding habitat needs of priority wetland-dependent wildlife. 

Please note that these profiles are limited to birds found in Mesa & Delta Counties.

Tamarisk biocontrol alters bird community composition in the absence of cottonwood and willow vegetation
Invasive species disturb ecosystems and threaten biodiversity. Invasive species management, such as biological control, can cause additional disturbances, so quantifying how native species respond to invasive control is important to inform best management practices.   Mahoney et al. quantified southwestern bird communities in sites that varied in the amount of the non-native plant tamarisk (Tamarix spp.), before and after biological control efforts.

Lessons Learned for Successful Watershed Partnerships in the Colorado River Basin

What are the key ingredients of successful collaborative partnerships? What worked well and what did not? If we had to do it all over again, what would we do differently? This document, based on interviews with stakeholders from 11 watershed partnerships in the Colorado River Basin, discusses the successes and challenges encountered from initial partnership formation to maintaining momentum over the years. It informs how RiversEdge West and other partners can continue contributing to the long-term success and viability of watershed partnerships.

Renewing Our Rivers: Stream Corridor Restoration in Dryland Regions
Our rivers are in crisis and the need for river restoration has never been more urgent. Water security and biodiversity indices for all of the world’s major rivers have declined due to pollution, diversions, impoundments, fragmented flows, introduced and invasive species, and many other abuses.   Developing successful restoration responses are essential. Renewing Our Rivers addresses this need head-on with examples of how to design and implement stream-corridor restoration projects.

Integrated Pest Management Plan: Bill Williams River National Wildlife Refuge

An Integrated Pest Management Plan for the Bill Williams River National Wildlife Refuge. This plan outlines the biological degradation of native riparian forest habitat along the Lower Colorado River and the invasive species management actions needed to protect and restore riparian forests and marshlands of the Bill Williams River.

Functional stability of vegetation following biocontrol of an invasive riparian shrub

From the abstract:

An understanding of trait-environment relationships is particularly important in the case of invasive species which may alter abiotic conditions and available resources. This study is the first to measure the functional response of riparian plant communities to biocontrol of an invasive species.

Salinity driven interactions between plant growth and a biological control agent

A two-part study looking at how changes in soil salinity affect tamarisk growth and how beetle-induced defoliation affects tamarisk growing in soils with different salinities. Results showed that tamarisk plants grow better in soils with a similar salinity to their own origin site and that lower salinity does not benefit tamarisk plants adapted to higher saline conditions.

Riparian Plant Communities Remain Stable in Response to a Second Cycle of Tamarix Biocontrol Defoliation

A look at beetle-occupied tamarisk sites 11-13 years after initial occupancy to determine long-term vegetative community response. Study found that Tamarix cover across sites initially declined an average of ca. 50% in response to the beetle, but then recovered. Changes in the associated plant community were small but supported common management goals, including a 47% average increase in cover of a native shrub (Salix exigua), and no secondary invasions by other non-native plants.
