Description
This is the Reference Plant Community given an unaltered disturbance regime.
Submodel
Description
In this state, the site is being managed for livestock grazing. This may lead to altered plant community composition and production where plants adapted to grazing disturbance may increase while those sensitive to disturbance may decrease. Additionally, impacts to the abiotic conditions of the site may occur as soil is compacted due to hoof trampling or eroded due to an increase in bare ground.
Submodel
Mechanism
Catastrophic fire, prolonged inappropriate grazing management
Context dependence
Invasive species must be present onsite or within a sufficiently close distance for dispersal from nearby invaded sites
Mechanism
Extended rest from grazing, possible reseeding of native grasses
Context dependence
Excessive grazing leading to a loss of plant species diversity, plant reproductive output or altered abiotic conditions, such as compacted or eroded soil that will not recover by rest alone and will require additional inputs
