BOTANY COLLECTIONS

• Collecting of botany specimens in

Northwest Territories and Nunavut peaked

in the 1960s, and in subsequent decades

collecting was fairly consistent through

time, based on Canadian Museum of

Nature collections data. The sustained

focus on Arctic flora research at CMN

explains the pattern in recent decades.

• By contrast, botany collections from

Nunavut and Northwest Territories housed

in numerous other Canadian collections

demonstrates a strong decline in collecting

since the 1960s, similar to the trends

observed for zoology collections.

The critical role of natural history collections in documenting biodiversity of the Arctic in the past, present and future

Jeffery M. Saarela - jsaarela@mus-nature.caDirector, Centre for Arctic Knowledge and Exploration

• Natural history collections housed in museums, herbaria and

universities represent the planet’s permanent record of biodiversity

in time and space.

• Estimates of the total number of natural history collections range

from 1.2-3 billion. Data for only 10-20% of these (ca. 118.5 million

specimens) are digitized and available through the Global

Biodiversity Information Facility (GBIF).

• Arctic natural history collections are a diverse, valuable and

irreplaceable component of the polar information spectrum. The

total number, spatial and temporal distribution, and taxonomic

composition of Arctic natural history is not known, because (1) most

collections are not digitized; (2) many digitized collections are not

geo-referenced, so not all Arctic records can be found in map-based

searches; (3) Arctic specimens and digitized collection data are

distributed across many different institutions and repositories; and

(4) it is difficult to count collections by ecozone.

• Collections are often used in ways that were unanticipated by the

original collectors. We cannot predict all the future questions that

today’s Arctic specimens may help answer.

• Arctic Observing programs on biodiversity should document

field observations with specimens whenever possible, and

should engage with natural history museums to ensure these

specimens are properly preserved and accessible to future

generations of researchers.

• Natural history museums need to be more involved in Arctic

science discussions to raise awareness and increase usage of

their collections, and should engage with researchers who

require a permanent repository for their Arctic collections.

Arctic Policy and Arctic Natural History Museums

• Online collections data from Canadian natural history collections provides strong evidence for a substantial decline in

Arctic collecting since the 1960s. This trend needs to be reversed to understand Arctic biodiversity through time.

• Although not all Canadian Arctic collections have been digitized and duplicate specimens housed at different institutions were not

removed from the analyses, the observed patterns based on available data are likely robust.

• The U.S.-Canada Joint Statement on Climate, Energy and Arctic

Leadership (10 March 2016) calls on Arctic nations to embrace a new

future for Arctic leadership, with one objective being conserving Arctic

biodiversity through science-based decision making: “Canada and the U.S.

re-affirm our national goals of protecting at least 17% of land areas and 10% of

marine areas by 2020.”

• In the Canadian Arctic only 11.7% of terrestrial and freshwater and 0.8%

of marine territory are currently protected (Environment Canada 2016).

• Biodiversity in existing and new Arctic protected areas needs to be

comprehensively and systematically surveyed and documented by

specimens, to establish a current and robust baseline of information, and

the resultant specimens should be housed in permanent collections like

the Canadian Museum of Nature and made accessible digitally, enabling

researchers and the public to learn about – and value – the Arctic natural

world.

• The Arctic Natural History Museum Alliance, founded in 2013, comprises the national natural history

museums of the eight Arctic Council states. The Alliance aims to work together to actively share their Arctic

knowledge with the science community, public policy decision-makers and the general public, and is focussing

on collections digitization, research contribution and collaboration, and impactful public programming and

outreach.

There are far fewer natural history collections from the Arctic than from temperate and

tropical areas, based on the ca. 118.5 million specimens records available from the Global

Biodiversity Information Facility (GBIF). Many Arctic areas have not been inventoried.

• The members of the Arctic Natural History Museum Alliance collectively

house some 243 million specimens. The total number of Arctic collections

in these institutions is not known, but likely represents a considerable

proportion of the planet’s total Arctic collections.

ZOOLOGY COLLECTIONS

• Collecting of zoological specimens from

Northwest Territories and Nunavut peaked

in the 1960s, declined slowly during the

next two decades and then rapidly declined

from 1981 onwards, based on Canadian

Museum of Nature collection data.

• The pattern is similar based on zoological

specimens from Northwest Territories and

Nunavut in numerous other Canadian

institutions, except the peak was in the

1970s and the decline over the next 30 years

was stronger. However, there was a

substantial increase in collecting activity

from 2010 onwards.
