Tuktut Nogait National Park and vicinityMelville Hills Region

• area identified as under-explored botanically• plant collecting by Scotter & Zoltai as part of resource inventory 1990

Cody, W., G. Scotter, and S. Zoltai. 1992. Vascular plant flora of the Melville Hills Region, Northwest Territories. Canadian field-naturalist 106: 87-99.

• very few collections before, some by Park staff after, none at CAN

teamed up with Parks Canada plant inventory and vegetation plots for monitoring

Fieldwork in Tuktut Nogait National Park

• how to travel?• community concern re flights

disturbing caribou• Parks suggested traveling by

canoe – joint Parks canoe patrol & botanical expedition

• a first for us! and a logistical challenge
