Introduction

• We will talk deeply on 8 questions
• 1)Where can we find woodland in Hong Kong today?
• 2)What are the characteristics of woodland in
  Hong Kong?
• 3)What are the problems of woodland in Hong Kong?
• 4)What are the causes of the problems?
• 5)How do these problems affect our lives?
• 6)Are we able to solve the problems?
• 7)What is the best use of our woodland?
• 8)How can we help protect our woodland and
  tropical rainforests?

Where can we find woodland in Hong Kong today?

• Shing Mun Country Park (? ? ? ? ? ? )
• The richest woodlands can be found in Shing Mun
  Valley at the northern end of the reservoir
  facing Lead Mine Pass.
• Since the 1970's, many representative flora
  species have been planted here. At the last count
  in 2000, this green sanctuary boasted more 7,000
  trees belonging to over 270 species native to
  Hong Kong or Southern China. Among them are many
  rare and endangered species. Indeed, the
  arboretum plays a vital role in flora
  conservation.
• Ecological Highlights
• Shing Mun Country Park is famous for its profuse
  woodlands. In front of the lake one finds the
  original site of the old Tai Wai village. Nearby
  is a fung shui wood harbouring magnificent old
  trees belonging to more than 70 species.
• Public Transport Information
• Shing Mun Reservoir
• In Siu Wo Street, Tsuen Wan, take green minibus
  no. 82 to Pineapple Dam of Shing Mun Reservoir,
  or take bus no. 40X, 46X, 47X, 48X, 73X or 278X
  to Ho Fung College on Wo Yi Hop Road. After
  getting off the bus, walk along Shing Mun Road
  for 30 minutes to Pineapple Dam. From there, it
  is a 20-minute walk to the main dam and barbecue
  area.

Where can we find woodland in Hong Kong today?

• Pokfulam Country Park (? ? ? ? ? ? ?)
• The 2.2 km Pokfulam Native Tree Walk features
  Hong Kong's native plant species. Winding along
  Lugard Road by the Peak Galleria, this short
  route takes about 45 minutes to complete.
• the Agriculture, Fisheries and Conservation
  Department has put in continued efforts to green
  the valley. Over the year, a great number of
  introduced species have been planted
• Peak Trail
• Take bus no. 15 or 515 or green minibus no. 1 to
  the Peak.

Where can we find woodland in Hong Kong today?

• Hong Kong Park
• The park site is quite steep but amid the old
  vegetation are good specimens of large trees,
  which were originally planted by the military.
  Most of the trees have been retained during the
  development
• Forsgate Conservatory( ?????)
• The Forsgate Conservatory comprises three
  sections, namely the "Display Plant House", the
  "Dry Plant House" and the "Humid Plant House".
  Adjustable environmental control equipment is
  installed in the Conservatory to provide a range
  of climatic conditions so that everything from a
  tropical rain forest environment to an arid
  desert condition can be simulated.
• Vegetation of the Edward Youde Aviary (????? ????
  )
• Some mature trees existed in the valley before
  the aviary was built and the majority of these
  were preserved during the construction work.
• Many new trees have been planted but it will take
  several years before these mature to enhance the
  tree canopy.
• Transportation
• MTR Admiralty Station C1 exit
• BUS 1, 1M, 3B, 5, 5A,
• PLB 1A, 24A

7
What are the causes of the problems?

• The first reason is for lands. Hong Kong is a
  small place but there are many people. We want
  more houses and roads for improving our living
  conditions. Therefore, people cut many trees.

8
What are the causes of the problems?

• 2) The second reason is hill fire. In winter and
  autumn, the weather in Hong Kong is dry so fire
  is easily caused. It is very difficult to put out
  fire at a forest because fire can spread quickly
  by wind. Therefore, fire can destroy many trees
  in a short period of time.

9
How do the problems affect our lives?

• Logging and burning of trees can cause many
  problems that would affect our live

10
How do the problems affect our lives?

• 1) Climatic Change
• The most serious consequence is that of climate
  change due to the loss of trees. Earth has an
  atmosphere which contains a variety of gases ,
  one of these gases in Earths atmosphere is
  carbon dioxide. If there are additional
  greenhouse gases, there will be a gradual
  increase in temperature on Earths surface. This
  could lead to changes in weather patterns, sea
  levels, and other cycles in nature that directly
  affect our life .
• The only way to help moderate the levels of
  carbon dioxide in the atmosphere is through plant
  life. Alive plants and trees absorb the carbon
  dioxide from decaying plants and trees. With a
  decrease in trees and plant life (due to
  deforestation), it is much harder to moderate
  these levels.

11
How do the problems affect our lives?

• 2) Erosion
• Although these forests assume to be lush and
  full, the underlying soils are very poor, almost
  all the nutrients being bound up in the
  vegetation. The problem is that once forests have
  been cut down, essential nutrients are washed out
  of the soil all-together. This leads to soil
  erosion.

12
How do the problems affect our lives?

• 3) Poor air quality
• Burning the trees puts a great amount of ashes
  into the atmosphere . As the forests have been
  cleared , the rate of photosynthesis (the trees
  absorb carbon dioxide and release a large amount
  of oxygen to support the living things .)become
  lower , so that causes poor air quality.

13
Are we able to solve the problems?

• Ans Yes.
• Problem1) Cut trees.
• Solution1) We must use two sides of each paper.
  Dont waste paper.
• Solution2) The buildings can be built higher to
  save land.

14
Are we able to solve the problems?

• Problem2) Hill fire.
• Solution1) In Ching Ming festival, we must put
  out the fire after worshiping the ancestors.
• Solution2) Dont leave lighted fire after having
  barbecue.

15
How can we help protect our woodland and tropical
rainforests?

• We can learn more about the rainforests. (visit
  the websites about the environment organizations,
  read books about the rainforests in the world
  etc), then we know how to take action to protect
  them.
• 2) We can plant local species of trees.

16
How can we help protect our woodland and tropical
rainforests?

• We can support environment organizations.lte.g.
  World Wildlife Fund, green power and green peace
  etc...gt (e.g. donating money, being volunteers
  etc)
• We can look for ways to reduce the paper use.
  (Try using both sides of every sheet of paper,
  using recycled paper and reusing envelopes etc...)

17
How can we help protect our woodland and tropical
rainforests?

• We should not take plants or pick flowers from
  anywhere in the wild environment.
• 6) We can think carefully before we decide to buy
  or use items made from woods . If you do decide
  to buy them, look for woods that are marked with
  a Forest Stewardship Council label.

18
How can we help protect our woodland and tropical
rainforests?

• 7) We can recycle your used papers. (Old
  newspaper and books etc...)
• 8) We can use cloth napkins rather than
  disposable napkins.

19
What are the problems of woodland in Hong Kong?

• Cut too many trees.
• 2) Hill fire.
