Decline in Pl Peace Region #35

Open Vcomea opened 1 month ago

Vcomea commented 1 month ago

Decline in Pl feasibility in the Peace Region on dry and zonal sites = BWBSmw. Future BGCs are SBSmh (Pl=E2/E1) near Quesnel, SBAPcp (no Pl) near Edmonton, and BWBSdmN (some site types projected do not contain Pl) Grand Prairie to High Level area.

• Loss of Pl feasibility is driven by a shift to SBAP units (Sub-Boreal Aspen Parkland) which do not support Pl on dry or zonal sites. • SBSmh (along the Fraser River, Quesnel to PG) is projected for this area as well, further into the future, Pl = E1/E2 for site series projected onto BWBSmw/101. • This is a lower elevation area, in the rain shadow of the Rocky Mountains, which is projected to become drier. image BWBSmw/101 (C4): image image BWBSmw/102 (B2): image 2041-2060: image 2081-2100: image

Climate drivers: Increasing temperatures Summer precip = neutral -> physiological drought w/ warmer temps Winter/autumn/spring = precip is projected to increase (btwn 10-29% by 2100) image image
