Suber Stand Level Simulator

SUBER simulator integrates SUBER growth model specifically developed for cork oak species in Portugal. A description of the tool as well as a users’ manual can be found in Paulo (2011). This simulator can be used for:

    • Characterizing properties
    • Defining management units
    • Simulating the development of a stand under diferent management approaches
    • Simulating cork production
    • Preparing management plans
    • Research purposes

 The inputs required to run SUBER are:

    • Tree level inputs and cork information
    • Climatic variables from the closest meteorological station
    • Management prescription
    • Economic data

SUBER is suited to simulate the evolution of a stand using inventory data. The simulator estimates the evolution of each stand in the input with an annual time-step producing average output for all the stands. If preferred the trees in all stands can be considered as part of a big stand (area equal to the sum of the individual stands).

Simulation results are presented for each year of simulation in text files containing tree, plot or stand information. SUBER can be downloaded at Downloads after registration and login.

Additionally a web tool to assist managers deciding whether to debark, WebCorky, was developed. WebCorky predicts the growth of cork for a set of cork samples of known caliber, which is classified according to the industrial norms. When no analysis to cork quality has been made, this web tool provides an empirical classification (editable by the user) that allows to estimate an average cork value over time based on a table of prices (caliber versus quality) also user-editable.
