We recorded 196 taxa in Katannilik Territorial Park ; 145 of these taxa are first records for the park. We recorded 170 taxa in Kimmirut and vicinity  in Kimmirut and vicinity; 15 of these taxa are first records for Kimmirut and vicinity. All study area species are native, except two grasses that grew in Kimmirut: F.rubrasubsp.rubra, which may have been seeded and Hordeumjubatumsubsp.jubatum, of unknown origin. We summarize the distribution on Baffin Island for each taxon recorded in the study area, including several unpublished southern Baffin Island records.The Arctic ecozone is undergoing a rapid transformation in response to climate change. Establishing a baseline of current Arctic biodiversity is necessary to be able to track changes in species diversity and distribution over time. Here, we report a vascular plant floristic study of Katannilik Territorial Park, Kimmirut and vicinity within Circumpolar Arctic Bioclimate Subzone D on southern Baffin Island, Nunavut, Canada. We compiled a dataset of 1596 collections gathered in the study area throughout the last century, including 838 we made in 2012. The vascular flora comprises 35 families, 98 genera, 211 species, two nothospecies and seven infraspecific taxa. We newly recorded 51 taxa in 22 families in the study area:  The Arctic is warming more than twice as fast as the rest of the planet due to climate change. Due to this rapid warming, the Arctic environment is undergoing many changes. October 2020 to September 2021 was the Arctic’s seventh-warmest 12-month period on record. During this period, the surface air temperature anomaly for land north of 60° was 1.1 °C above the 1980–2010 mean . North AWarming air temperature, sea ice decline, changing snow cover and changing permafrost influence Arctic vegetation. Satellite observations show that yearly maximum tundra vegetation greenness, a tundra productivity measure, increased across most of the Arctic between 1982 and 2020 . BrowninDespite the rapid Arctic vegetation changes occurring and predicted over the coming decades, knowledge gaps remain in our understanding of the Arctic vascular flora’s diversity and distribution. Researchers have studied and documented the Canadian Arctic vascular flora for over 150 years , 2018. YBaffin Island, Nunavut, is Canada’s largest island and Earth’s fifth-largest island Fig. . Over thqikiqtaaluk means “very big island.” Hudson Strait separates Baffin Island from the Canadian mainland and Baffin Bay and Davis Strait separate it from Greenland. Southern Baffin Island includes Meta Incognita Peninsula, a highland area reaching an elevation of ca. 914 m , ca. 26 km southeast of Kimmirut, to ca. 26 km west-northwest. At low tide, freshwater flows from Tasiujarjuaq into Pleasant Inlet. Just east of Pleasant Inlet is Glasgow (Westbourne) Bay, a large inlet that extends northwest ca. 18 km from North Bay.The Soper River enters Katannilik Territorial Park ca. 13 km north-northwest of Mount Joy (elevation 562 m). Mount Joy, just north of the Joy and Soper rivers’ confluence, is one of the park’s prominent geographic features. It portrays a human face on its southern slope; kimmirut means "heel", referring to a marble outcrop near the community resembling the heel of a foot. Until 1 January 1996, Kimmirut was named Lake Harbour. An Anglican Church was erected in the community in 1909 and the Hudson’s Bay Company set up a trading post there in 1911. 2 and its elevation is 53 m. Its population in 2016 was 398  . Today,  was 398 . KinngaiThe Soper River valley’s substrate is mainly till, outwash, deltaic gravel and sandy alluvium. Calcareous outcrops, including marble and crystalline limestone, occur just north of the Soper and Livingstone rivers’ confluence . Much ofThe Arctic bioclimate zone has an Arctic climate, Arctic flora and tundra vegetation. The Circumpolar Arctic Vegetation Map divided this circumpolar zone into five bioclimate subzones named A to E, defined by summer temperature and vegetation characteristics . SubzoneSouthern Baffin Island spans two bioclimate subzones. The ca. western third of Foxe Peninsula and adjacent islands fall within Subzone C. This subzone has a 5–7 °C mean July temperature, 5–50% vascular plant cover, a moss layer 3–5 cm thick, a herbaceous layer 5–10 cm tall, dwarf shrubs less than 15 cm tall and local vascular floras with 75 to 150 species. The rest of southern Baffin Island, including the study area, falls within Subzone D, which extends north to ca. 67°47'N. This subzone has a 7–9 °C mean July temperature, 50–80% vascular plant cover, a moss layer 5–10 cm thick, herbaceous and dwarf shrub layers 10–40 cm tall and local vascular floras with 125 to 250 species. Elsewhere in Canada, Subzone D includes southern Banks, Southampton and Victoria islands and much of the mainland Arctic. Following earlier North American Arctic vegetation classifications, the study area's vegetation is Low Arctic , low ereResearchers divide the circumpolar Arctic into 21 floristic provinces, delimited primarily based on vascular plant species distributions .

We collWe studied the flora of Katannilik Territorial Park and vicinity from 30 June to 23 July 2012. We conducted research under a Nunavut Territorial Parks Use Permit, Nunavut Wildlife Research Permit WL 2012-034, Nunavut Water Board Permit 3 BC-FAA1212, Qikiqtani Inuit Association Certificate of Exemption (Access to Inuit Owned Land) Q12X016 and Polar Continental Shelf Program Project Number 515-12. We explored botanical diversity along the Soper River while travelling by inflatable canoe from Mount Joy to Soper Falls. We spent 20 days within the park and four days outside the park, in Kimmirut and vicinity.63°14'52"N, 69°36'28"W), at group/warden cabin #7 , at the Livingstone River and Soper River confluence , on the east riverbank south of emergency shelter #8  and at the Soper Falls campground . We established a final camp at Taqaiqsirvik Territorial Park (campground) in Kimmirut . We explored each camp area on foot, seeking out as many habitats as possible and aiming to record all vascular plant species present in each area with at least one collection. While travelling between camps, we stopped to collect at two willow thickets along the river (13 July) and the lapis lazuli occurrence (16 July). Labels on our specimens from the lapis lazuli site  mistakenly indicate it is within Katannilik Territorial Park; it is not. On 17–18 July, we collected near Soper Falls. On 19 July, we collected on a small unnamed island within Tasiujarjuaq and outside the park, around the Kimmirut boat landing and Reversing Falls. On 20, 22 and 24 July, we collected in Kimmirut and vicinity. On 21 July, we collected along Pleasant Inlet, west of Kimmirut, travelling via a boat charter from the hamlet. Fig. We flew from Iqaluit to “Paradise Flats” near Mount Joy, our starting point, by Twin Otter plane, which landed on the airstrip there. We established six field camps along the Soper River: at the airstrip  at the Canadian Museum of Nature and have distributed duplicates to the following herbaria, as indicated in the specimen citations: University of Alaska Museum of the North (ALA); University of Alberta Vascular Plant Herbarium (ALTA); Arizona State University (ASU); Gray Herbarium, Harvard University (GH); University of Michigan (MICH); Bell Museum, University of Minnesota (MIN); Missouri Botanical Garden (MO); Marie-Victorin Herbarium, University of Montreal (MT); The Rooms Provincial Museum, Newfoundland and Labrador (NFM); William and Lynda Steere Herbarium, New York Botanical Garden (NY); Botanical Museum, Oslo (O); Herbier Louis-Marie, Université Laval (QFA); Norwegian University of Science and Technology (TRH); Beaty Biodiversity Museum, University of British Columbia (UBC); United States National Herbarium, National Museum of Natural History, Smithsonian Institution (US); Intermountain Herbarium, Utah State University (UTC); University of Victoria (UVIC); University of Manitoba Herbarium (WIN); Wilfred Laurier University (WLU); University of Washington (WTU).We dried specimens in a standard plant press in the field. During processing, we subsampled specimens for a small amount of leaf tissue preserved in silica gel desiccant; we tagged the plant subsampled when possible. We have deposited all tissue samples in the Canadian Museum of Nature’s National Biodiversity Cryobank of Canada. J.M. Saarela, P.C. Sokoloff and L.J. Gillespie identified specimens. We have deposited a complete set of specimens in the CAN, DAO, MIN, QFA and H (where we only searched through the monocots). Through direct enquiries to collection managers and searches on the Global Biodiversity Information Facility (GBIF) platform, we examined and confirmed specimen images from the E.C. Smith Herbarium at Acadia University (ACAD), ALTA, the general herbarium of vascular plants at the University of Copenhagen (C), the herbarium at the Field Museum of Natural History (F), GH, the herbarium at the Royal Botanic Gardens, Kew (K), the R.L. McGregor Herbarium at the University of Kansas (KANU), the herbarium at the Botanical Museum, Lund University (LD), MICH, MIN, MO, MT, the herbarium at McGill University, Macdonald Campus (MTMG), NY, O, the herbarium at the Swedish Museum of Natural History (S), the Green Plant Herbarium, Royal Ontario Museum (TRT), US, UTC and the herbarium at the Royal British Columbia Museum (V).To generate a comprehensive checklist of the study area’s vascular flora, we attempted to account for all plant collections gathered therein. We searched the literature, herbaria and online collection databases to locate vascular plant specimens collected in the study area. We manually searched the collections at GH include handwritten collection numbers on separate pieces of paper, which we assume are fragments of the paper in which he pressed his specimens. To match numbered collections at GH with duplicates at CAN and elsewhere that exclude these numbers, we relied on the six-digit number on the label. We cite these in the checklist as s.n./[collection number] followed by the six-digit number in square brackets.Malte’s specimen labels do not include collection numbers, but they bear unique six-digit numbers from an older National Herbarium of Canada number series. We used these numbers to identify duplicate specimens amongst herbaria and we cite this number in square brackets for each of Malte’s collections in the checklist to unambiguously refer to them. In addition to the specimen label from the National Herbarium of Canada, a subset of Malte’s collections housed at 63°10'N, 69°55'W.

We alsoGBIF)-mediated collection data that have not been published or included in maps. We accepted records discovered on GBIF for which we could confirm a specimen determination, based on an image. For all sites on Baffin Island for which records have not been published, we cite the collector, collector number, herbarium and accession or barcode number. Furthermore, through careful cross-checking of vouchered occurrence data on GBIF with distribution maps from CAN, we revealed some mapping errors; we describe these errors in the text.We also summarize the known distribution on Baffin Island for each taxon recorded in the study area. These summaries include site-level descriptions of collection localities on the Meta Incognita Peninsula, Foxe Peninsula and Hall Peninsula, as well as on islands immediately adjacent to Baffin Island, such as Dorset, Mallik and Resolution islands. We refer to these regions as southern Baffin Island. Sometimes, we summarize all known occurrences of a taxon on Baffin Island .

In that paper, we also included our study area collections of Andromedapolifolia L. and Pinguiculavulgaris L.; we reported both as new in other parts of the Canadian Arctic Archipelago. We do not repeat the information We previously published a subset of our 2012 collections that are new records for one or more of Baffin Island , the eastern Canadian Arctic Archipelago, the Canadian Arctic Archipelago or Nunavut . These tOur final dataset includes 1596 unique vascular plant collections from the study area. We gathered 838 of these collections in 2012 and other collectors gathered 758 before 2012. Our 2012 collections comprise 676 gatherings from Katannilik Territorial Park, 11 from the lapis lazuli site outside the park, 111 from Kimmirut and vicinity and 41 from Pleasant Inlet. Of the prior collections, 671 were gathered in Kimmirut and vicinity, 81 within what is now Katannilik Territorial Park and six at the lapis lazuli site. The number of specimens recorded in our database gathered by each prior collector is as follows: Aiken & Iles (27), Archambault (18), Blake (1), Dutilly (83), Fleming (2), Johansen (35), Malte (316), Oldenburg (44), Polunin (132), Sanson (2), Soper (96) and Tallman (2).Poaceae is the most diverse within the study area, with 15 genera, followed by Ericaceae with 11, Caryophyllaceae with nine, Brassicaceae with seven and Asteraceae with six. Two families comprise four genera, three comprise three, eight comprise two and 17 comprise one. At the species level and below, the largest families, each with ten or more species, are Cyperaceae (38 species), Poaceae (24), Brassicaceae (16), Caryophyllaceae (16), Ericaceae (13), Saxifragaceae (11), Asteraceae (11) and Juncaceae (10). Two infraspecific taxa occur within the study area in Eriophorumscheuchzeri Hoppe, Poaarctica R.Br. and Potentillahyparctica Malte. We did not count putative hybrids between Salix species (see comments under S.arctophila in the checklist) as separate taxa.The study area’s vascular flora comprises 35 families, 98 genera, 211 species, two nothospecies and seven infraspecific taxa  are amongst the eight families with the highest species richness in the circumpolar Arctic , Polunin six , Malte and Polunin one (Huperziaarctica), Sanson one , Polunin and our team one [Puccinelliavaginata (Lange) Fernald & Weath.], Malte and our team one  and our team seven . Some or all these taxa may occur within Katannilik Territorial Park, where they have not been recorded. We do not know if the 11 taxa recorded in Kimmirut and vicinity before 2012 and not found by us in 2012, persist there.Our study area included three main subregions: Katannilik Territorial Park, Kimmirut and vicinity (outside the park boundary) and along Pleasant Inlet. We recorded 19 taxa only in Kimmirut and vicinity Table , where fAntennariafriesiana(Trautv.)E.Ekmansubsp.friesiana in the park, Soper first collected Chamaenerionangustifolium(L.)Scop.subsp.angustifolium, Dryopterisfragrans (L.) Schott, Ranunculusnivalis L., R.pygmaeus Wahlenb. and Salixplanifolia in what is now the park and Johansen first collected Potentillacrantzii (Crantz) Beck in what is now the park. We recorded two taxa only from Pleasant Inlet (Carexsubspathacea Wormsk. and Plantagomaritima L.), where we collected them in 2012. Both species occur on seashores, so they likely do not occur within Katannilik Territorial Park, but they may occur elsewhere in the area.We recorded 46 taxa only in Katannilik Territorial Park Table . We collAlopecurusborealis, in 1938 and Polunin or Malte collected the rest  in 1936 or earlier. Some of these occurrences are significant regionally. The Saginanodosasubsp.borealis collection is the taxon’s only Baffin Island record. Equisetumscirpoides is not recorded elsewhere on Baffin Island, but is recorded from adjacent Dorset Island. Coptidiumpallasii is recorded elsewhere on Baffin Island and the Canadian Arctic Archipelago only in Iqaluit. Brayaglabellasubsp.glabella is recorded elsewhere on Baffin Island only in Iqaluit. We do not know if these species still exist within the study area. None of them has been recorded there in 84 or more years.We recorded 28 taxa in the study area based on a single record. Eight of these are historical collections. Sanson collected one of them, Andromedapolifolia, Arenarialongipedunculata, Carexkrausei Boeckeler, C.subspathacea, Cryptogrammastelleri, Eriophorum×mediumsubsp.album J.Cay., E.scheuchzerisubsp.arcticum, Festucaproliferavar.lasiolepis Fernald, F.rubrasubsp.arctica (Hack.)

Many of these records are regionally significant. The Andromedapolifolia record is the only one from the eastern Canadian Arctic Archipelago. The Arenarialongipedunculata record is the only one from the Canadian Arctic Archipelago and Nunavut. The Cryptogrammastelleri, Leymusmollissubsp.mollis and Festucaproliferavar.lasiolepis records are the only ones from the Canadian Arctic Archipelago. The F.rubrasubsp.arctica record is the only one from Baffin Island. The Utriculariaochroleuca record is the only one from the Canadian Arctic Archipelago and Nunavut.We collected the remaining 20 taxa known in the study area from a single record in 2012, namely Astragaluseucosmus B.L.Rob., Bartsiaalpina L., Calamagrostiscanadensissubsp.langsdorffii (Link) Hultén, Campanularotundifolia L., Carexarctogena Harry Sm., Chamaenerionangustifoliumsubsp.angustifolium, Coptidium×spitsbergense, C.lapponicum (L.)

Another subset of species in this area is recorded from southern Baffin Island and Southampton Island, including Carexnorvegica Retz., C.williamsii Britton and Oxytropispodocarpa.The study region’s vascular flora includes several species whose south-eastern Canadian Arctic Archipelago distributions are largely restricted to Circumpolar Arctic Bioclimate Subzone D. In the eastern Canadian Arctic, this subzone includes Coats Island, south-western Southampton Island and southern Baffin Island north to Cumberland Sound’s north shore and adjacent islands, but excluding western Foxe Peninsula and adjacent islands .

Including the two taxa we here report as new to the Canadian Arctic Archipelago  brings the number of species and infraspecific vascular plant taxa known in the Canadian Arctic Archipelago to 387. Fifty-seven percent of the Canadian Arctic Archipelago’s vascular flora occurs within the study area, including several taxa not known elsewhere within the Canadian Arctic Archipelago, namely Arenarialongipedunculata, Carexbrunnescenssubsp.brunnescens, Coptidium×spitsbergense, Cryptogrammastelleri, Leymusmollissubsp.mollis, Platantheraobtusatasubsp.obtusata, Primulaegaliksensis, Salixfuscescens, Utriculariaochroleuca and Triglochinpalustris.The Canadian Arctic Archipelago’s known vascular plant flora continues to increase as researchers survey unexplored areas. hipelago , reporte2) is nearly 80 times larger than Ovayok (16 km2). Furthermore, the former contains considerable habitat diversity, whereas the latter centres on Uvayuq, an esker with less habitat diversity. Similarly, Kugluk (10.5 km2) is 120 times smaller than Katannilik Territorial Park. Despite its much smaller area, its vascular species richness is six percent greater than that of Katannilik Territorial Park. We attribute the richer vascular plant diversity in Kugluk Territorial Park compared to Katannilik Territorial Park to three factors. First, Kugluk Territorial Park’s mainland location within the milder Bioclimate Subzone E (vs. Subzone D) favours greater species diversity in local floras. Indeed, the park includes several primarily boreal-distributed species that reach or are near their northern limits in Nunavut within the park, in the Coppermine River valley. Second, Kugluk Territorial Park has considerable habitat diversity despite its small size and third, it is easier to characterize the flora of a small area such as Kugluk Territorial Park, which can be traversed on foot, than a much larger area such as Katannilik Territorial Park. About 1.9 times more species are recorded in Katannilik Territorial Park than in Mallikjuak Territorial Park (ca. 40 km2), although knowledge of Mallikjuak's flora is incomplete , a common name, a summary of the global distribution, voucher information and comments.
