NAME Dinosaur Provincial Park
IUCN MANAGEMENT CATEGORY
II (National Park)
Natural World Heritage Site - Criteria i, iii
BIOGEOGRAPHICAL PROVINCE 1.18.11 (Grasslands)
GEOGRAPHICAL LOCATION Approximately 50km north-east
of Brooks in south-east Alberta. 50°49'N, 111°36'W
DATE AND HISTORY OF ESTABLISHMENT Created as
Steveville Dinosaur Provincial Park on 27 June 1955 under the Alberta
Provincial Parks Act. Inscribed on the World Heritage List in 1979. The
boundary was modified in 1993 to accommodate natural gas deposits under
the park.
AREA 7,493ha (formerly 6,622ha)
LAND TENURE Crown, Province of Alberta. Originally
the park included both Crown and private land. The Provincial Parks Act
of 1974 limited the application of park status to Crown-owned or leased
land and the 2,959ha of private land at Dinosaur Park no longer fell within
the power of the Act.
ALTITUDE Ranges from 621m to 727m
PHYSICAL FEATURES The site is an outstanding
example of fluvial erosion patterns in semi-arid steppes; slow-moving
rivers that emptied into the shallow Bearpaw Sea 75 million years ago
left deposits which have ultimately developed into the clay shale and
sandstone observed today. About 15,000 years ago this area was flat and
covered by an ice sheet some 600m thick. During this ice age, glacial
meltwater carved steep-sided channels; ice crystals, wind and flowing
water continued to shape these extensive 'badlands' which today display
a variety of representative features including hoodoos, mesas, buttes,
knife-edge divides, piping features, pseudokarst terrain, miniature pediments,
ephemeral streams and bentonitic clays. Differential weathering by water
erosion continues to expose a variety of bedrock. About 6% of the area
is occupied by significant and, for the most part, undisturbed riparian
habitat, shaped by the meandering channel of the Red Deer River and characterised
by point bars, wide terraces, fans and cutbanks (Anon, 1979).
CLIMATE Mean annual temperature is 3.8ēC and
mean annual precipitation is 406mm (recorded at an altitude of 730m).
VEGETATION The river terraces support lush and
diverse vegetation in various successional stages, ranging from pioneer
willow stands to structurally complex plains, cottonwood forest, tall
shrub thickets, ephemeral wetlands and dense sagebrush flats. Plains cottonwood
riparian communities are among the most threatened habitats in semi-arid
regions. The 'badlands' provide habitat for a number of ecologically specialized
plant species and are characterized by open vegetation dominated by plants
of the genus Artemisia and the family Chenopodiaceae. Remnant and
recently created grasslands occur on buttes and large pediments. Threatened
species, or those at the limit of their biogeographical ranges, include
Stephanomeria runcinata, Orobanche ludoviciana, Atriplex
powellii (E), A. suckleyi, Oryzopsis micrantha, Lupinus
pusillus, Plantago elongata, Muhlenbergia racemosa,
Erigonium cernuum and Antennaria dimorpha.
FAUNA Geological strata of the Judith River
formation, deposited 75 million years ago, have yielded many of the dinosaur
remains for which the park is renowned. Some 38 species of over 34 genera
of 12 families of dinosaurs have been found in the Park (Alberta Environmental
Protection, pers. comm., 1995), including specimens from every known group
of dinosaurs from the Cretaceous period. The families Hadrasauridae, Ornithomimidae,
Tyrannosauridae, Nodosauridae, Pachycephalosauridae and Ceratopsidae are
best represented. Other fossil remains include fish, turtles, marsupials
and amphibians.
The mild winter microclimate, coupled with an abundant
food supply, provides critical winter range for native ungulates such
as pronghorn Antilocapra
americana, mule deer Odocoileus
hemionus and white-tailed deer O.
virginianus. The relative richness and abundance of breeding avifauna
is noteworthy. Over 150 species of bird have been recorded. The area supports
a number of species locally threatened or at their biogeographical limits,
including golden eagle Aquila
chrysaetos, prairie falcon Falco
mexicanus, ferruginous hawk Buteo
regalis, loggerhead shrike Lanius
ludovicianus, merlin Falco
columbarius, Brewers sparrow Spizella
breweri and grasshopper sparrow Ammodramus
savannarum. Plains spadefoot toad Scaphiopus
bombifrons also occurs (Dinosaur Provincial Park fact sheet, 1986).
CULTURAL HERITAGE Several archaeological sites
representative of the native 'Plains Indian Culture' have been found,
including a 'Vision Quest' site, a stone effigy and Tipi rings.
LOCAL HUMAN POPULATION Brook, a community of
10,000 inhabitants, lies about 50km south of the provincial park (Alberta
Environmental Protection, pers. comm., 1995).
VISITORS AND VISITOR FACILITIES Campsites, picnic
areas, hiking trails and a visitor education programme with on-site interpretation
facilities are provided.
SCIENTIFIC RESEARCH AND FACILITIES Long-term
palaeotological research and monitoring programmes are in progress, particularly
on the fossil beds, which are the most extensive in Canada. A drainage
basin has been set aside in the natural preserve for on-going geomorphic
process research. The park was surveyed and subsequently included in the
International Biological Programme. All scientific studies and research
are rigidly controlledthrough a parks research and collection permit system.
A field station of the Royal Tyrell Museum of Palaeonotology has been
constructed in the park and opened in May 1987. This field station supports
the palaeotological research activities undertaken in the park and provides
a public educational/interpretive facility.
CONSERVATION VALUE The park is of great international
palaeotological significance and includes representations of dinosaurs
from the Late Cretaceous Period. Between 1979 and 1991, a total of 23,347
fossil specimens were collected, including 300 dinosaur skeletons from
at least 35 distinct species. In addition, the Red Deer River supports
riparian habitats which includes structurally complex plains cottonwood
forest, whilst the badland terrain, which is subject to erosion, continually
exposes bedrock (Anon, 1991).
CONSERVATION MANAGEMENT An administration office
is located at the field station of the Royal Tyrell Museum. All palaeotological,
prehistoric/historic resources are protected both on private and crown
lands under the provisions of the Alberta Historical Resources Act 1978.
There is no zoning system, except for the establishment of a Natural Preserve
in 1970 which allows visitor access to be controlled and thus helps preserve
the major palaeotological and geomorphological features. A resource management
plan was completed in April 1990. A general management plan is being prepared
to formally direct and provide for future use, development, management,
interpretation and education, and will be completed in 1996 (Alberta Environmental
Protection, pers. comm., 1995).
MANAGEMENT CONSTRAINTS Five gas wells were drilled
in the park, prior to it being inscribed on the World Heritage List. Three
are now abandoned, the other two will be phased out and reclaimed over
time. However, a programme of gas-well development occurs on lands surrounding
the park, and includes an unspecified number of gas wells and ancillary
pipelines on upland areas north and south of the Red Deer River. Gas wells
are allowed with a 150m setback from the top of the badlands slopes. Gas
well projects take place only under stringent conditions to minimise impacts
(Anon, 1991). There are no grazing leases inside the park, and there are
no plans to extinguish those outside the park (J. Thorsell, pers. comm.,
1995).
STAFF As of 1995, full time staff comprises
two rangers, one visitor services officer, one maintenance service worker
and one support staff. Three rangers, six interpreters and four maintenance
service workers are employed during the summer season (Alberta Environmental
Protection, pers. comm., 1995).
BUDGET Can $419,573 (1995), not including capital
funding (Alberta Environmental Protection, pers. comm., 1995).
