Transcript of Wollemi Pine

The Wollemi Pine
By Annie Zhang, Christina Deng, Lily Liu

Wollemia nobilis
Environment: New South Wales, Austrailia
Climate: Hot summers and cool summers with moderate rainfall.
Background
The common name is Wollemia Pine.
The scientific name for Wollemi Pine is Wollemia nobilis.
The kingdom for this plant is Plantae.
The class of this plant is Pinopsida.
It belongs in the Araucariacease family.
Biotic and Abiotic Factors
Biotic:





Abiotic:

Challenges
Habitat fragmentation
Deforestation
Climate change
Habitat loss
Adaptation to Present Day Environment
Average height: 35 meters
The Wollemi Pine has needle-like leaves
Produces through wind pollination and vegetatively (asexual reproduction)
Its bark has a bumpy surface caused by spongy swellings on trunks
Male cones are reddish-brown and narrow
Female cones are green to brown and narrow
Adaptation to Environment in 25,000 Years
Due to climate change, the climate will become drier, and there will be less rainfall.
Leaves will develop thicker cuticles to keep the moisture in.
Sharper and pointier leaves to help rainwater drip down to the roots.
Adaptation to Environment in 50,000 Years
Sharper leaves evolve into larger, pointier leaves.
Develops thicker layer of cuticle to absorb more moisture.
The pine's height grows 2 more meters. (Height: appx. 37m)
Adaptation to Environment in 100,000 Years
Extreme climate and global warming leads to heat waves.
The pine produces a thicker trunk and bark to protect against wildfires.
Summary
The height of the pine will gradually increase to obtain sunlight
Leaves develop a thicker cuticle to keep in moisture.
Leaves will become pointier and sharper.
Male cones will mature year-round to release pollen
The bark and the trunk shall thicken to prevent contact from wildfires.

The challenges given in the environment
forces the pine to evolve through variation
as well as mutation to adapt in order
to be successful in the future

Climate Change
Humans overexceed carry capacity, causing severe destruction of habitats
Male cones will pollinate year round like female cones to be more successful.
Heat intensity increases due to global warming.
Layer of cuticle thickens to keep in moisture.
Sharper leaf and larger size to aid water in dripping to soil.
Height increases by 3 meters (Height appx. 40m)
