Little is known about how cultivation legacies affect the outcome of rehabilitation seedings in the Great Basin, even though both
frequently co-occur on the same lands. Similarly, there is little known about how these legacies affect native species re-establishment
into these seedings. We examined these legacy effects by comparing areas...
Because invasive annual grasses can strongly influence soil resource availability and disturbance regimes to favor their own
persistence, there is a great need to understand the interrelationships among invasive plant abundance, resource availability, and
desirable species prominence. These interrelationships were studied in two salt desert sites where the local abundance...
In the late 1950s, "two California men" came to Oregon to learn if there were abalone here, and found them in the southern part of the state. The resulting publicity and interest inspired this document, an attempt to develop regulations for a new fishery. It is an internal discussion paper...
Advancing our ability to use invasive plants for producing commodities is central to the agricultural industry. Our objective was
to evaluate Russian knapweed (Acroptilon repens [L.] DC.) as a winter feed supplement for ruminant livestock. In Experiment
1, we utilized three ruminally cannulated steers in a completely randomized design to...
Producers facing infestations of invasive annual grasses regularly voice the need for practical revegetation strategies that can be applied across broad landscapes. Our objective was to determine the potential for scaling up the single-entry approach for revegetating medusahead-infested rangeland to broader, more heterogeneous landscape-scale revegetation of winter annual grass–infested rangeland....
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...
The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...
Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...
Curly dock (Rumex crispus L.) is a perennial. It does
not have creeping roots or rhizomes (Figure 1). Leaves
are oblong to nearly lanceshaped, often 12 inches or more
long, with wavy (crisped) margins (Figure 2). Erect, generally
unbranched stems up to 5 feet tall are produced in spring
and...
