Want to find out more about eYield? Have questions about the Simulator? Browse or search our Frequently Asked Questions, below, or Contact Us for more information.
- Can I simulate multiple stands in batch mode?
- Currently, this is not an option. Perhaps in the future we will build this into eYield, if support becomes available.
- Can I use eYield on my smart phone?
- We are designing eYield to work on personal computers, tablets, and smart phones. Some functions such as saving a scenario file or downloading simulation results may vary based on the device and the operating system being used.
- How is eYield different from WinYield?
- We have tried to emulate as closely as possible the processes in WinYield for growing, merchandizing, and valuing a stand of trees. At this point in time (summer 2023), eYield is still undergoing development. Comments and suggestions are welcome.
- What inspired the development of eYield?
- Many foresters interested in modeling the biological and economic potential of natural forests of the eastern United States enjoyed using the WinYield model, which was initially developed by the Tennessee Valley Authority in the 1980s. WinYield was a software program supported by many organizations through the early 2000s. Our goal was to enable foresters access to an Internet version of WinYield that focused on natural pine and hardwood forests, and perhaps was updated with new growth and yield knowledge that has been developed over the last two decades.
- What simulators are available in eYield?
- The simulators that are available in eYield include oak-hickory, natural loblolly pine, natural longleaf pine, natural shortleaf pine, natural slash pine, white pine, and yellow-poplar simulators that were available in WinYield. Since planted pine simulators are being developed by others, these are not planned for eYield. However, eYield does recognize the reforestation costs involved in harvesting a natural stand and regenerating the land with a plantation.
- Why does eYield focus on natural forests rather than (or in addition to) plantations?
- There are a number of efforts aimed at providing the public with biological and economic pine plantation systems. For example, the Plantation Management Research Cooperative at the University of Georgia is developing a pine plantation system for free public use. We did not want to duplicate these efforts in eYield.
- Why not use WinYield?
- The WinYield software model is no longer continually managed to keep up with developments in computer technology and computer operating systems. Therefore, a centralized, Internet-based service seems to be the best option in today's environment.
