Permanent Sample Plots (PSP)
Understand how the forest growsATLAS PSP enables the forest manager to ensure reliable data is available about permanent sample plots (PSPs). PSPs are periodically assessed to record changes in growth over time and in relation to silviculture and other events. This information supports sound forest management, forest valuation and silvicultural management. An intrinsic feature of this type of data is the length of period over which it is collected, usually over many years. By using a traditional relational database with scope for recording a wide range of attributes, ATLAS PSP is designed to minimise the effects of changes in staff and computer systems over time. The PSP application is based on a system that was initiated in the 1970s and the PSP installation at Scion now includes over 190,000 records of plot measurements for over 100 species.
