Undergrowth layer –Main features

Page 3: Vegetation in SFCC Group members: F.5A Christy Chan F.5C May Chan (5) Kelly Chiu (9) Joyce Ng (26)

Undergrowth layer –Main features

1. Roots• Buttress rootsÞ To provide

mechanical support of trees against weight and wind

Þ To absorb nutrients at once

Undergrowth layer –Main features

Undergrowth layer –Main features2. Leaves• Thick & Waxy surfaceÞ To prevent excess water

loss through transpiration

• Oval-shaped• Narrow crown due to

the lack of sunlight• Darker leaves=> To absorb more sunlight

Undergrowth layer –Main features

Page 7: Vegetation in SFCC Group members: F.5A Christy Chan F.5C May Chan (5) Kelly Chiu (9) Joyce Ng (26)

Undergrowth layer –Main features

• Height: shortÞ Due to lack of nutrients

from sunlight to grow taller

• Drip-tip leavesÞ To shed the excess water

away• Narrow crown due to the

lack of sunlight• Darker leavesÞ To absorb more sunlight

Physical constraints on the growth of vegetation in SFCC

Lithosphere• Dry soil (because

of heavy leaching)

Adaptation• Shallow rootsÞ To absorb

nutrients from top soil quickly

Page 9: Vegetation in SFCC Group members: F.5A Christy Chan F.5C May Chan (5) Kelly Chiu (9) Joyce Ng (26)

Undergrowth layer –Physical constraints

-Competition of nutrients:There are other type of plants growing near or even on the trees, they have shared the nutrients absorbing in the soil, hence less nutrients can be absorbed from the roots.

Which vegetation in SFCC impresses you most?

This shrub located beside such a huge tree, mainly all the nutrients in the soil are absorbed by the buttress roots from the huge tree, but this hasn’t hindered the growth of shrub. Therefore, this shrub in SFCC impresses us most because of its strong vitality and adaptation.
