Location: Range and Meadow Forage Management Research

2013 Annual Report

1a. Objectives (from AD-416):
Model seedling population dynamics.

1b. Approach (from AD-416):
The approach is use the data collected by ARS in this project to model the short term seedling population dynamics.

3. Progress Report:
The work conducted on this project relates to Objective 1 of the parent project, "Develop a new biological control tool to reduce the species performance of cheatgrass and medusahead on rangelands". Significant progress on the objective of this project will not be made until the data collection described in the parent project is completed. In 2013, we assisted cooperators in designing a sampling protocol that will lead to collecting data necessary to build the population models. This work was accomplished over email, phone calls, and during two field trips to the Nevada field sites; the first in November of 2012, and the second in May of 2013. This collaboration ensures that the data we are collecting will allow us to successfully conduct the full spectrum of analyses we proposed.
