Pinyon Jay-Piñon Pine Mutualism

Trees:

• abundant seeds in mast

years

• seeds high in fat, protein

• nest sites

Jays:

• long-distance dispersal of

millions of seeds

• cache seeds in open sites

such as burned areas

• cache seeds in micro-

habitats favorable for

germination

• can re-plant a woodland

decimated by drought, fire,

insects, or clearing

Pinyon Jay-Piñon Pine

Coevolved Traits

Jays:

• expandable esophagus

• phenomenal spatial memory

• physiological response to green piñon cones

• nest in all seasons

• insulated nests

• large pointed bills for opening green cones

• naked nostrils

Trees

• large, wingless seeds require dispersal by animals

• irregular masting

• seeds highly nutritional

• cones open upwards for bird dispersal

Potential

Threats

Historical• Clearcutting for mining,

1800s (timber and charcoal)

• Millions of acres chained for grazing, tree invasion

Recent• Climate impacts to

P-J habitat

• Thinning for fuels reduction,

ecological condition

• Tree removal for sage-grouse

• Development

Documented Climate Impacts

to Piñon Trees

• models predict P-J range will

contract*

• models predict massive tree mortality in SW*

• tree mortality*

• declines in cone production*

• decreases in canopy cover*

* documented by studies

Expected Climate Impacts

to Pinyon Jays*

• canopy cover - nests exposed to predators

• needle loss – nests exposed to heat

• fewer cones – impact jay reproductive success

• tree mortality – nest trees isolated, more visible to predators

• tree morbidity, mortality – suitable colony sites scarce

• range of Pinyon Jays predicted to contract 25-31%, 2010-2099

*based on well documented PIJA natural history

Thinning Treatments Affect

Habitat Suitability

Nesting

• Tree density*

• Tree size*

• Canopy cover*

Foraging

• Masting trees

• Ectomycorrhizal fungi

*documented by studies

Tree Removal for Other Species:

Greater Sage-Grouse

Development: Oil and Gas

• Habitat loss

• Habitat fragmentation

• reduced patch size

• patch isolation

• Well noise*

*documented by studies
