This Addendum describes the decision-support products the Arid Lands Initiative has developed and is using to facilitate partners’ transition from landscape planning to taking coordinate action guided by shared priorities, as the ALI partners strive to achieve landscape-scale conservation in eastern Washington’s arid lands.
Abstract (from ScienceDirect): Altered climate and changing fire regimes are synergistically impacting forest communities globally, resulting in deviations from historical norms and creation of novel successional dynamics. These changes are particularly important when considering the stability of a keystone species such as quaking aspen (Populus tremuloides Michx.), which contributes critical ecosystem services across its broad North American range. As a relatively drought intolerant species, projected changes of altered precipitation timing, amount, and type (e.g. snow or rain) may influence aspen response to fire, especially in moisture-limited and winter precipitation-dominated portions of its range. Aspen is...
When the Earth experiences changes in climate, wildlife respond by moving – species adjust their ranges to stay within climatically suitable habitat, moving out of areas that become too hot or otherwise inhospitable, and moving into areas that become newly hospitable. However, climate change is now proceeding so quickly that it is becoming difficult for species to move fast enough to keep pace. In addition, today’s landscapes feature significant barriers to wildlife movement due to human land use (e.g., highways, cities, agriculture). Such is the case in the region surrounding the border of Washington state, USA, and British Columbia, Canada, where increasing development pressure and limited coordination of land...
This is a protocol that seeks to protect a federally recognized American Indian tribe’s intellectual property (IP) and traditional knowledge (TK) from unapproved usage, while securing a process through which research ed information can be effectively obtained and disseminated. While acknowledging that each American Indian community may vary regarding its own unique protocol practices, the following document covers four sets of principles and issues which are over-arching recommendations for developing positive communications and collaborative research relationships between a tribe(s) and researchers funded by federal and/or state agencies. Illustrative case examples will be provided throughout this document that...

The Pacific Region National Wildlife Refuge System developed a strategic approach to identify region-wide land/habitat conservation priorities. This approach was piloted in the Columbia Plateau Ecoregion and resulted in a high-level landscape-scale conservation design. Working closely with conservation partners in the region, we developed a data management and analysis model that builds from existing data sets and can be shared easily with other partners.

This dataset contains the data described in Looney and Eigenbrode's 2012 Natural Areas journal article (Characteristics and Distribution of Palouse Prairie Remnants: Implications for Conservation Planning), including potential Palouse remnants, a boundary for the study area, and a set of potential remnants that lay outside of the study area. While the potential remnants inside the area were reviewed based on limited ground-truthing described in the article, those outside the area were not. As such, there are likely potential remnants that are in fact re-colonized field margins or drainage ditches, or CRP-like plantings. Since the focus was primarily on eyebrows located in agricultural contexts, many of the river...

Cold-induced mortality is a key factor driving mountain pine beetle( Dendroctonus ponderosae) population dynamics. In this species, the supercooling point (SCP) is representative of mortality induced by acute cold exposure. Mountain pine beetle SCP and associated cold-induced mortality fluctuate throughout a generation, with the highest SCPs prior to and following winter. Using observed SCPs of field-collected D. ponderosae larvae throughout the developmental season and associated phloem temperatures, we developed a mechanistic model that describes the SCP distribution of a population as a function of daily changes in the temperature-dependent processes leading to gain and loss of cold tolerance. It is based on...

These two datasets represent a normalized least-cost corridor mosaic (see WHCWG 2010 and McRae and Kavanagh 2011) calculated using (1) temperature gradients and a landscape integrity resistance raster, or (2) temperature gradients only, following the climate gradient linkage-modeling methods outlined in Nuñez (2011), using an adapted version of the Linkage Mapper software (McRae and Kavanagh 2011). This GIS dataset is one of several climate connectivity analyses produced by Tristan Nuñez for a Master's thesis (Nuñez 2011). The dataset was produced in part to assist the Climate Change Subgroup of the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The core areas in the map lie in Washington State...
Based upon the research developed in association with the Sqigwts NKN Climate Change project, this document provides recommendations on how to design inter - actable food producing “Gardens” (the term defined later in this document), with appropriate Indigenous content and pedagogical considerations relating to climate change. The Garden could be used by the Tribe at their discretion to identify, protect and perpetuate the use and locations of traditional, native plants used in the traditional seasonal round . It seeks to demonstrate that both indigenous and sc ientific knowledge can be successfully applied in this endeavor. It seeks to be an educational venue for students and their teachers, and to be a sustainable...

This dataset is an extract of the resistance surface created for the Pacific Northwest Duke Climate Resilience Project. It incorporates data on various human activities from the following data sources: National Landcover Dataset, Energy Infrastructure data from the Ventyx Corporation, National Wetlands Inventory, TIGER 2010 Road Data, active railroads and Dave Theobald's housing density dataset developed from 2010 census data. More details on the creation of this surface can be found in the document "Creation of Resistance Surfaces for the Resistant Kernel Pacific Northwest Duke Landscape Resilience Project".
We established a Landsat-derived geospatial database of unburned islands within 2,298 fires across the Inland Northwestern US (including eastern Washington, eastern Oregon, and Idaho) from 1984-2014. The detection of unburned areas within these fires is based upon a classification tree approach that uses two pre- and post-fire Landsat image pairs (see Meddens et al 2016 for details). The data set consist of unburned patches within each fire that are two pixels or larger. This database will be useful for identifying fire refugia, seed sources, and can be used as an overall metric of fire impacts across the northwestern US. (Meddens, A.J., Kolden, C.A., & Lutz, J.A. (2016). Detecting unburned areas within wildfire...
Abstract (from http://www.sciencedirect.com/science/article/pii/S0034425716303261): Wildfires shape the distribution and structure of vegetation across the inland northwestern United States. However, fire activity is expected to increase given the current rate of climate change, with uncertain outcomes. A fire impact that has not been widely addressed is the development of unburned islands; areas within the fire perimeter that do not burn. These areas function as critical ecological refugia for biota during or following wildfires, but they have been largely ignored in methodological studies of remote sensing assessing fire severity under the assumption that they will be detected by algorithms for delineating fire...
This project identifies priority areas in the Columbia Plateau Ecoregion to implement conservation 4 strategies for riverine and riparian habitat. This is tailored towards the Arid Lands Initiative (ALI) conservation goals and objectives, and provides the foundation for adaptation to a changing climate. This project adopts a “zoned” approach to identifying focal areas, connectivity management zones and zones for riparian habitat and ecological representation. Through a series of workshops and webinars, the ALI articulated its freshwater conservation goals and targets. Key aspects of these goals included: a focus on non-anadromous salmonid (salmon and steelhead) species, include riparian birds and waterfowl as key...
