Restoration of Shrub Steppe Ecosystems Active
This research theme provides land managers information to help them make restoration decision at local and landscape scales.
Millions of acres of shrub-grassland ecosystems are in need of restoration in the western United States. For lands degraded by invasive annual grasses, we have been studying best management practices for restoring ecosystem function through using either native or introduced plant species. On lands with degraded herbaceous layers, we are attempting to restore grasses and forbs without destroying the shrubs. In addition, we are providing land managers with handbooks to use in making restoration decisions at local and landscape scales.

This document presents a long-term research strategy designed to address current and future research needs for management of Department of the Interior-administered ecosystems in the Intermountain West. Although the research plan was developed in the context of the Interior Columbia Basin Ecosystem Management Project, the plan addresses many high-priority issues facing land managers throughout theAuthorsErik A. Beever, David A. PykeStrategic plan for the Coordinated Intermountain Restoration Project
In 1982, the Bureau of Land Management’s (BLM) Idaho State Office began the Intermountain Greenstripping and Rehabilitation Research Project (IGRRP), or the “Greenstripping Program,” to investigate plant materials and technologies that can reduce wildfire incidence and improve rehabilitation practices. Rehabilitation is normally applied as a reactive process to wildfires, yet land managers in theAuthorsDavid A. Pyke, Michael L. PellantRamet spacing of Elymus lanceolatus (thickspike wheatgrass) in response to neighbour density
Many plants exploit patchy resources through clonal foraging. Plants established in field plots were used to determine if Elymus lanceolatus ssp. lanceolatus (Scribner et J.G. Smith) Gould (thickspike wheatgrass) showed a clonal foraging response to neighbour densities, as it had previously shown to patchy soil nutrients. Neighbours consisted of the rhizomatous E. lanceolatus ssp. lanceolatus andAuthorsL. David Humphrey, David A. PykeEffects of nutrient patches and root systems on the clonal plasticity of a rhizomatous grass
Clonal plant foraging has been examined primarily on individual clones exposed to resource-poor and resource-rich environments. We designed an experiment to examine the clonal foraging behavior of the rhizomatous grass Elymus lanceolatus ssp. lanceolatus under the influence of neighboring plant root systems in a heterogeneous nutrient environment. Individual Elymus clones were planted in large binAuthorsElisabeth Huber-Sannwald, David A. Pyke, M. M. Caldwell, Susan DurhamVariability in seed dormancy of three Pacific Northwestern grasses

The advantages of guerrilla and phalanx growth for the guerrilla Elymus lanceolatus ssp. lanceolatus and phalanx E. l. ssp. wawawaiensis were evaluated over 2 years in two taxon mixtures with a range of densities of each subspecies and under two levels of watering. Ramet numbers and biomass of the guerrilla subspecies were higher than those of the phalanx grass in the first year but in the secoAuthorsL. David Humphrey, David A. PykePerception of neighboring plants by rhizomes and roots: Morphological manifestations of a clonal plant
A previous study showed that clonal morphology of the rhizomatous grass Elymus lanceolatus ssp. lanceolatus (Scibner & J.G. Smith Gould) was influenced more by neighbouring root systems than by the local distribution of nutrients. In this study we determine whether individual rhizomes or roots of E. lanceolatus perceive neighbouring root systems and how this is manifested in morphological responseAuthorsElisabeth Huber-Sannwald, M.

1. Foraging by means of plasticity in placement of tillers in response to low- and high-nutrient patches was examined in the rhizomatous wheatgrass Elymus lanceolatus ssp. lanceolatus. Its ability to exploit soil nutrient patches was compared to that of the closely related but caespitose E. lanceolatus ssp. wawawaiensis.2.
