States 1 and 5 (additional transitions)

T1A - Armillaria Root Rot State in which the forest has been converted to a shrubland
T1B - Fire exclusion over long periods allowing stands to grow into homogenous, dense, multi-storied stands.
T1C - Housing and road development within Douglas fir forest that reduces forest patch size, increases edge and decreases interior acreage of intact forest and ecological services
T1D - Forest stand with understory dominated by weedy invasive species or forest converted to cropland or pastureland. Introduced grasses and/or weedy species dominate the understory with overstory of Douglas fir or site is a cropland or pasture.
R2A - Forest management practices to convert shrubland back to forest including tree planting of less Armillaria Root Rot sensitive tree species
R3A - Forest stand structure, composition and historical fire regime restored by overstory thinning, ground and ladder fuels reduction, and prescribed fire.
R4A - Potentially not feasible; removal of housing and road development and restoration for Douglas fir overstory and perennial native bunchgrass understory.
R5A - Range management practices to convert introduced grass and/or weedy species dominated understory to native understory vegetation.
1.1A - Moderate sized patches of tree mortality due to fire, insect, disease, windthrow.
1.1B - Stand replacement disturbance. Severe Fire or insect mortality killing large pine/fir.
1.2A - Time and infilling of moderate sized patches with trees to a reference stand of multistory stand.
1.3A - Time with fire return interval extended to allow natural tree regeneration to grow into dense pole stands
1.4B - Stand replacing severe fire that returns the stem exclusion phase forest to the initiation phase
1.4A - Time without fire to allow vertical differentiation of stand through small gaps from death due to disease, insects, small fires, windthrow.
1.5A - Time with no major disturbance to transition to the reference phase community
1.5B - This is a severe stand replacing fire event that returns the community to the initiation phase
