Botanical Survey of Agguttinni Territorial Park, Baffin Island, Nunavut

This is the specimen dataset for a botanical inventory of Agguttinni Territorial Park (TP), located east of Kanngiqtugaapik [Clyde River] on the east-central coast of Baffin Island in the Qikiqtaaluk Region of Nunavut. Agguttinni TP is the largest territorial park in Nunavut, covering an area of about 1,646 km2, and stretching from Baffin Bay southwest to the Barnes Ice Cap. The park includes some of the most spectacular scenery in Canada, with ice-capped mountains and very long, deep fiords, and is known as an ecotourism and rock climbing destination. Its diverse topography results in the park having large microclimatic variation, many different habitats, and a correspondingly diverse flora and vegetation. The vascular plant flora of east-central Baffin Island has been little explored or documented. Most of our knowledge of this flora comes from plant and lichen collections made during the 1950 Baffin Island Expedition, which until now was the only botanical study focused in the region. Comprehensive results of their plant research were never published, although the vascular plant collections were used inmaking species distribution maps for the Illustrated Flora of the Canadian Arctic Archipelago (Porsild 1957), and more recently in the updated flora for that region by Aiken et al. (2007). Surprisingly, and in contrast to elsewhere in the Arctic, the lichen flora of this area was better documented with the publication The Lichens of Baffin Island (Hale 1954) by the expeditions lichenologist. The flora of the area included within the proposed boundary of Agguttinni TP is particularly poorly known. Given the general lack of knowledge of vascular plant diversity on east-central Baffin Island, and specifically within Agguttinni TP, we conducted a botanical survey of Agguttinni TP between July 22 and August 22, 2021. Additionally, we collected a small number of samples within the community of Clyde River.
