The Canadian Forest Service and the New Brunswick Department of
Natural Resources and Energy (NBDNRE) have cooperated to develop
an interactive database system in support of the N.B. Cooperative
Permanent Sample Plot (PSP) program. The program, initiated in 1987,
includes approximately 2500 PSPs located throughout the province.
These plots are representative of the entire provincial forest.
Data from the PSPs can be used to define stand structures at specific
points in time, calibrate stand growth models, and validate/invalidate
projections made with stand models. These growth projections or
yield curves represent the volume expectations that form the basis
for forest management plans.
Permanent Sample Plot Database (PSPDB) was created as a data management
and reporting system. Microsoft Access® is used to facilitate
access and transform the raw data into information using meaningful,
built-in calculations and a flexible graphical user interface (GUI).
PSPDB is updated annually by the New Brunswick Co-operative Growth & Yield Unit.Direct your enquires to the contact below.
A CFS Information Report M-X-209E/F presents an overview of the
N.B. Cooperative PSP program, the database structure and functions
of PSPDB, installation instructions, and a tutorial. Selected calculated
outputs from the system are also presented, including volume, periodic
annual increment, and periodic mortality, by geographic area (Crown
license and marketing board area), and by species class. This report
is available from our Publications section:
