These data were compiled to provide seed transfer and native plant materials development guidance to managers and practitioners across the Colorado Plateau and in adjacent regions. This data release contains empirical seed transfer zones derived from molecular genetic data for Cleome lutea (syn. Peritoma lutea) and Machaeranthera canescens (syn. Dieteria canescens). These species show distinct population structure (i.e., genetic differentiation) across their ranges; as such, seed transfer zones reflect both patterns of genetic differentiation and information on each species' unique adaptations to climatic gradients. These shapefile data may support successful restoration outcomes if, for example, seed transfer follows...

The UP was formalized in a 2001 Memorandum of Understanding/Cooperative Agreement by the Public Lands Partnership (PLP), Bureau of Land Management (BLM), Colorado Division of Wildlife (CDOW) and U.S. Forest Service (USFS). Western Area Power Administration (Western) and Tri-State Generation and Transmission Assoc. joined the partnership in 2004. The goal of the UP is to develop a collaborative approach to improve the ecosystem health and natural functions of the landscape, using best available science, community input and adaptive management. The primary UP programs are: Landscape Scale Project Planning, Invasive Species Management, a Native Plant Program, On-The-Ground Treatments, and Education and Technology Transfer....

These data were compiled to provide seed transfer and native plant materials development guidance to managers and practitioners across the Colorado Plateau and in adjacent regions. This data release contains empirical seed transfer zones derived from molecular genetic data for Pleuraphis jamesii (syn. Hilaria jamesii), Sphaeralcea parvifolia, and Sporobolus cryptandrus. Pleuraphis jamesii and Sphaeralcea parvifolia show distinct population structure (i.e., genetic differentiation) across their ranges ; as such, seed transfer zones reflect both patterns of genetic differentiation and information on each species' unique adaptations to climatic gradients. Sporobolus cryptandrus did not display discrete population structure...

As restoration needs for natural landscapes grow due to higher frequency and/or intensity disturbances, pressure from invasive species, and impacts resulting from changing climates, considerable time and resources are being invested to guide the development and deployment of native plant materials (NPMs). Across lower elevations of the Colorado Plateau, a region composed primarily of public land where arid conditions make restoration especially challenging, NPM coordination has been spearheaded the Bureau of Land Management’s Colorado Plateau Native Plant Program (CPNPP) since 2009. To help CPNPP achieve its vision of healthy and resilient native plant communities, the Southwest Biological Science Center (SBSC)...

Empirical evidence that local adaptation and home-site advantages are frequent across plant taxa has increased recognition that local adaptation plays a fundamental role in shaping plant responses to seed transfer (i.e., when plant materials are introduced to a site during restoration). Use of maladapted plant materials can lead to poor project outcomes if propagules exhibit poor germination or seedling survival, low population fitness, inbreeding or outbreeding depression. Accounting for local adaptation in restoration designs is a promising approach for increasing revegetation effectiveness, particularly in drylands where extreme environmental variation potentially drives high levels of selection. Consequently,...
* 1 Abandoned agricultural (AA) fields are often invaded by exotic plants. This observation has been difficult to explain because agricultural practices change nearly every aspect of an ecosystem. Restoring native plants to AA fields is likely to require a prioritized understanding of the many mechanisms through which agriculture encourages exotic and discourages native plant growth. * 2 Using 660 experimental plots in three sites in Methow Valley, Washington, USA, we determined the relative role of neighbour removal, propagule addition, plant?soil feedback, soil disturbance and fungal restriction to explain why exotics cover 38% of the ground in AA fields and 3% of the ground in non-agricultural (NA) fields. *...

Seed sourcing strategies that incorporate spatially explicit genetic information promote effective revegetation by reducing genetic risk factors, such as maladaptation, outbreeding, and inbreeding depression. Molecular markers represent an increasingly robust and cost- efficient data source for uncovering patterns of adaptive divergence in high-priority species to support restoration decision making. This project uses marker-based genetic analyses to develop empirical seed transfer zones for species that have been genotyped at a wide range of sites in the Mojave Desert. Empirical seed transfer zones delineate areas within which seeds may be transferred with limited risk of maladaptation or outbreeding depression....
