Wildlife Program OverviewMason Reid, Wildlife EcologistMount Rainier National Park

NPS Mission and Policies

Organic Act and NPS Policies– which purpose is to conserve the scenery and

the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations. (16 USC 1)

Role of Wildlife Program at Mount Rainier

Responsible for the protection and understanding of wildlifeEvaluate impairmentAt Mount Rainier you can find:

– at least 56 mammal species;

– 17 species of amphibians and reptiles; – more than 229 species of birds use the park; – 8 species of native fish;

– but invertebrates probably represent 85% of the animal biomass in the park

Protecting Ecosystems – Intact??

Status of Ecological Integrity - Wildlife

Park establishment – Protects communities within the park

Many mid-larger size vertebrates are far rangingPark “island effect”Old growth forests, subalpine meadows – appear

largely intactMissing most of the system’s carnivores –many

others in decline – significant implications

Endangered Species Act of 1973

All Federal agencies are required to undertake programs for the conservation of endangered and threatened species, and are prohibited from authorizing, funding, or carrying out any action that will jeopardize a listed species or destroy or modify its "critical habitat" [section 7];

ESA in place to recover species in jeopardy

Park Project Effects on Wildlife

Construction/maintenance project effects on wildlife

– Direct – roadkill mortality

– Indirect – habitat loss; noise, lights and other disturbance; artificial food sources

Northern Spotted Owl

Barred Owl

Larger and more aggressive than spotted owl.

Same genus (Strix) as spotted owl.

Considered a threat to NSO but only recently some supporting evidence

Demographic Monitoring Approach

Northern Spotted Owl Status

Marbled MurreletBrachyramphus marmoratus

Listed as a threatened species by both the U.S. Fish and Wildlife Service and the state of Washington.

Marbled murrelet nesting habitat in the Park is forests older than 100 years and below 3,500 feet.

There are approximately 10,000 ha (25,000 acres) of suitable marbled murrelet nesting habitat in the Park.

Breeding areas– Carbon– Mowich– Puyallup

Occupied– Nisqually

Suitable– Ohanapecosh (?)– White

Murrelet Monitoring

Presence/Absence– Portable Marine

Radar• Detects flying

murrelets

Breeding– Audiovisual surveys

• Vocalizations

• Flight behavior

Network Monitoring

North Coast and Cascades Network (NCCN)

7 Parks, 28 Networks in NPS“Vital Signs”Long-term natural resource monitoring

program

Elk Monitoring – NCCNCervus elaphus

Identified as important to monitor in MORA, OLYM and LEWI

Monitoring protocol under developmentElk have an important ecological role and

are highly bio-political species (tribes, state, others)

Long history of elk issues

Elk Monitoring -- NCCN

Most elk in park are migratory – few reside year-round (Ohanapecosh watershed)

North and South HerdsAerial surveys – AutumnOne of the longest-running annual

monitoring programs at MORA

Landbird Monitoring --NCCN

- Point counts to determine trends and bird density in selected areas of the park

- Sample design with transects that start off roads and trails parkwide

Climate Change - Wildlife

Effects– Habitat loss– Changes in Distribution– Changes in Abundance– Changes in Phenology (Breeding, Migration,

More Climate Change Effects

– Increase of Diseases & Pests– Non-native definitions– Extirpations– Loss of species before they are identified

Human Dimensions of Wildlife

Around the Park– Landscape fragmentation– Wildlife persecution/harvest– Road corridors– Other development– Contaminants– Range Expansion/Non-natives

Human Dimensions of Wildlife

Within the Park – Roadkill– Boundary impacts– Park development projects– Visitor-caused disturbance– Wildlife feeding– Wildlife habituation
