Development of the science of riparian ecology in the semi-arid western United States [Chapter 1]

Publications Posted on: November 27, 2018
The science of riparian ecology in the West developed over several decades, especially in the Southwest and California, as the importance of this ecosystem, its components, productivity, functions, and relationship to system hydrology became better understood.

Riparian research and management: Past, present, future: Volume 1

Publications Posted on: November 19, 2018
Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico.

Supporting data for "Morphologic plasticity and increasing competition explain deviation from the Metabolic Scaling Theory in semi-arid conifer forests, southwestern USA"

Datasets Posted on: March 15, 2018
This data publication includes tree measurements taken 2008-2010 in three mixed conifer forests: the Pinaleño Mountains and Santa Catalina Mountains in southeastern Arizona, and the Jemez Mountains (Valles Caldera National Preserve) in northern New Mexico. Tree data measured at all locations include: species, condition, diameter at breast height and maximum vertical height.

Restoring silvopastures with oak saplings: Effects of mulch and diameter class on survival, growth, and annual leaf-nutrient patterns

Publications Posted on: September 30, 2014
In Southwestern Spain, multifunctional silvopastoral systems consisting of pastureland and open oak woodlands are known as Dehesas. These, and other similar systems of the Mediterranean basin, are currently threatened by increasing intensive land use. As a consequence, oak regeneration is declining and is in need of adequate management and active restoration.

Long-term effects of seeding after wildfire on vegetation in Great Basin shrubland ecosystems

Publications Posted on: September 28, 2014
Invasive annual grasses alter fire regimes in shrubland ecosystems of the western USA, threatening ecosystem function and fragmenting habitats necessary for shrub-obligate species such as greater sage-grouse. Post-fire stabilization and rehabilitation treatments have been administered to stabilize soils, reduce invasive species spread and restore or establish sustainable ecosystems in which native species are well represented.

Detecting mortality induced structural and functional changes in a pinon-juniper woodland using Landsat and RapidEye time series

Publications Posted on: September 19, 2014
Pinon-juniper (PJ) woodlands have recently undergone dramatic drought-induced mortality, triggering broad scale structural changes in this extensive Southwestern US biome.

Development of vegetation based soil quality indices for mineralized terrane in arid and semi-arid regions

Publications Posted on: May 29, 2012
Soil quality indices (SQIs) are often management driven and attempt to describe key relationships between above- and below-ground parameters. In terrestrial systems, indices that were initially developed and modified for agroecosystems have been applied to non-agricultural systems in increasing number.
