Behavior | Description |
---|

Aggregated Mortality | Kills trees randomly to match a predetermined mortality rate, clumping together the deaths in both time and space. |

BC Mortality | Kills trees as a function of growth rate. |

Browsed Stochastic Mortality | Simulates the effects of herbivory by allowing different background mortality rates for browsed and unbrowsed trees. |

Climate and Competition Dependent Neighborhood Survival | Assesses tree survival as a function of mean annual temperature, water deficit, and neighbor adult basal area. For efficiency, it calculates survival rates for cells in a grid and assigns trees the survival probability of the grid cell in which they are found. |

Competition Mortality | Kills trees as a function of growth. Uses the results of the NCI growth behavior. |

Density Self-Thinning Mortality | Calculates the probability of mortality of an individual juvenile tree as a function of the density and mean diameter of the neighborhood trees. |

Exponential Growth and Resource-Based Mortality | Calculates probability of mortality as a function of growth and some second resource. |

GMF Mortality | Kills trees as a function of growth rate. |

Gompertz Density Self Thinning | Calculates the probability of mortality of an individual tree as a function of the density of conspecific neighborhood trees. |

Growth and Resource-Based Mortality | Calculates probability of survival as a function of growth and some second resource. |

Height-GLI Weibull Mortality with Browse | Calculates the probability of mortality using a Weibull function of tree height and GLI (light level). It can also simulate the effects of herbivory by using different parameters for browsed and unbrowsed trees. |

Insect Infestation Mortality | Causes mortality in trees that are infested with insects. |

Logistic Bi-Level Mortality | Calculates the probability of survival according to a logistic equation, with the possibility of two sets of parameters for each species: one for high-light conditions and one for low-light conditions. |

NCI Mortality | Uses multiple effects, including neighbor competitiveness, to calculate mortality rates. |

Post Harvest Skidding Mortality | Simulates an increase in mortality after harvesting attributable to skidding damage or other effects. |

Self Thinning | Uses a pseudo-density dependent function designed to increase the death rate in dense uniform-age stands. |

Senescence | Provides for an uptick in mortality rates among large adult trees. |

Size Dependent Logistic Mortality | Mortality rates are a logistic function of tree size. |

Stochastic Bi-Level Mortality - Storm Light | Applies a constant rate of mortality to trees, with different rates for high-light and low-light conditions. This works with the Storm Light behavior. |

Stochastic Bi-Level Mortality - GLI | Applies a constant rate of mortality to trees, with different rates for high-light and low-light conditions. This works with the GLI behavior. |

Stochastic Mortality | Produces background mortality by randomly choosing trees to die according to a specified rate. |

Suppression Duration Mortality | Evaluates mortality as a function of tree age. This is particularly useful for simulating suppression in seedlings. |

Temperature dependent neighborhood survival | Assesses tree survival as a function of mean annual temperature and neighbor adult basal area. For efficiency, it calculates survival rates for cells in a grid and assigns trees the survival probability of the grid cell in which they are found. |

Weibull Snag Mortality | Controls snag fall according to a Weibull function of snag age. |
