Spatial Patterns in a Prosopis – Juniperus Savannah
The Texas Journal of Agriculture and Natural Resources 30:63-77 (2017) 63 © Agricultural Consortium of Texas Spatial Patterns in a Prosopis – Juniperus Savannah Steven Dowhower Richard Teague*1 Department of Ecosystem Science and Management, Texas A&M University System, Texas A&M AgriLife Research Center, P.O. Box 1658, Vernon, TX, USA. ABSTRACT We determined the distribution patterns and distance to nearest neighbor for Prosopis glandulosa and Juniperus pinchotii trees and saplings in west Texas to examine the intra- and interspecific spacing patterns of juvenile and mature trees to relate these patterns to their establishment dynamics on deep and shallow soils. Ordination was used to compare microsite vegetation associated with open grassland habitat and habitat proximal to big and small Prosopis and Juniperus plants. Analysis of similarities provided a multivariate index and probability of differences of vegetation between and among groups. Big Juniperus trees were randomly distributed on both soils, while the big Prosopis trees were random on the deep soil but aggregated on the shallow soil. Saplings of both species were strongly aggregated on both soils. Big and small Juniperus plants were positively associated with the dominant, established Prosopis trees and with litter cover but were negatively associated with bare soil and C4 grasses. In contrast, small Prosopis plants were negatively associated with both Juniperus and Prosopis trees on either soil and were positively associated with bare soil and C4 grasses. Prosopis trees facilitate establishment of Juniperus on deep or shallow soils, but Prosopis presence is probably not necessary for Juniperus establishment on either soil. The presence of big and small Juniperus plants close to and under the canopies of Prosopis trees and the inability of Prosopis seedlings to establish near Prosopis or Juniperus plants indicates that Juniperus trees would eventually dominate on the deep as well as the shallow soils. -

Woodlands Author: Kerry Dooley Historically the Primary Interest Area for National Inventories Was Timber
Woodlands Author: Kerry Dooley Historically the primary interest area for national inventories was timber. Consequently, the national inventory framework and collection protocols were focused on productive timber- lands (USDA Forest Service 2005). Over time, information such as estimations of carbon sequestration, wildfire fuel loads, and nontimber forest products and services (e.g., biofuels and wildlife habitat) has become topics of increasing interest. The FIA program—the national inventory used in the United States—broadened the focus of its surveys to include non- timberland forests, including woodlands, better aligning with these changing focus areas. Woodlands generally occur in less productive growing condi- tions, such as the arid Southwestern United States. Woodlands provide much, if not all, of the same services provided by forests; that is, they function as important wildlife habitat, improve water quality, serve as carbon sinks (or sources, in the event of wildfires), and provide fuel during wildfire season. The species that comprise woodlands differ in characteristics from most trees. On average, woodland species tend to be slower growing, smaller in stature, and of a form with more forks and branches near the base of the tree. Woodland species often grow as clumps of stems rather than one central stem. Beyond the characteristics of the trees classified as woodland species, specific parameters pertain to classification of the land use category of woodlands, while the Resources Planning Act (RPA) derives calculations of woodland for this report from the FIA data, the FIA and RPA definitions of woodland differ somewhat, as outlined in the following paragraphs. Forest Inventory and Analysis Definitions and Parameters FIA defines woodlands strictly along the lines of species com- position and associated forest types, and considers woodlands a subset of forest lands. -
House-Senate Negotiators Announce Bipartisan Agreement on Final Farm Bill
House-Senate Negotiators Announce Bipartisan Agreement on Final Farm Bill Bill Reforms Agricultural Policy, Reduces Deficit, Grows Economy Jan 27, 2014 Issues: Farm Bill MEDIA CONTACT: Tamara Hinton, 202.225.0184 [email protected] WASHINGTON – House and Senate agriculture leaders today announced a bipartisan, bicameral agreement on a five-year farm bill that will reduce the deficit, grow the economy and provide certainty to the 16 million Americans whose jobs depend on agriculture. The Agricultural Act of 2014 contains major reforms, including eliminating the direct payments program, streamlining and consolidating numerous programs to improve their effectiveness and reduce duplication, and cutting down on program misuse. The bill also strengthens our nation's commitment to support farmers and ranchers affected by natural disasters or significant economic losses; and renews a national commitment to protect land, water, and other natural resources. "I am proud of our efforts to finish a farm bill conference report with significant savings and reforms," said Rep. Frank Lucas (R-OK), Chairman of the House Agriculture Committee. "We are putting in place sound policy that is good for farmers, ranchers, consumers, and those who have hit difficult times. I appreciate the work of everyone who helped in this process. We never lost sight of the goal, we never wavered in our commitment to enacting a five-year, comprehensive farm bill. I ask my colleagues to join me in supporting its passage." "Today's bipartisan agreement puts us on the verge of enacting a five-year Farm Bill that saves taxpayers billions, eliminates unnecessary subsidies, creates a more effective farm safety-net and helps farmers and businesses create jobs," said Sen.
