Lo-> Identify was in which we can reduce the factors affecting whale population

Endangered species means that the specific animal or thing is in trouble or endanger.

5 animals I chose to look at...

•  Maui dolphin
• White Heron
• Kakapo
• Fairy tern
• Sea Lion

Fairy tern: Population 35-40 They are found in the lower half of the North Peninsula. They are endangered by Rats,Cats,Dogs.

Maui dolphin: Population 55. They are found west cost of the North Island. They are endangered by Nets.

White Heron: Population 100-140. They are found Wetlands. They are endangered by Humans.

NZ Sea lion: Population 12,000. They are found Auckland Island,Campbell Island,Otago Peninsula. They are endangered Nets and Disease. 

Kakapo: Population 124.They are found Codfish Island (it is in the South Island) They are endangered by Stoats,Rats,Cats.

Task 2:

Muai Dolphin are endangered by Nets because people are fishing for there meat or some type of display. If they get hit they can't recover.

In 2004 there is 117 but it has gone down by 111 I estimate there would be atlest 55-60

What I would do to stop people from killing the Muai Dolphins is to create a under water cave type thing so they would be safe for them to breed and hunt. 

Lo-> Describe what the issues are in regards to the destruction of forests and what can be done to regenerate the forest.

We use trees for wood,Papper,candy wrappers, Cardboard.

• Kohekohe
• Karaka
• Silver fern
• Manuka
• Puriri

  

• Planting trees can help prevent erosion.
• Trees can live up to thousands of years 
• So trees can grown up to 100 meters
• The inside layer of the tree protects the outside layer of bark.

There are pests like the Polynesian rat that are endangering our forest.

In the last 200 years perdators have wreaked out land and our forest and our wildlife like our animals.

  

If we didn't have trees we would...

• wouldn't be able to breath because it has oxygen .It absorb carbon dioxide and releases oxygen.
• Trees cools the earths temperatures down. So If we didn't have trees the grass or the ground would be hot.
• Trees believe it or not are food because some trees have a type of seasoning leaf.
• Trees also have oil. If you don't have oil you can't do cooking.

• Going papperless
• Recycle and buy recycle products
• Eat vegan meals.

Palm oil is a type of oil that is in a tree. It is located were the orangutans live. Palm oil is in al most any product.

Snacks,Everyday products.

It is a reddish pulp that is an edible vegetable oil.

It effects the Orangutans because it is there home that is were there habitat.

We care about palm oil because some of our products that we use or eat has palm oil eg. Chocolate.

My plain is to make a trap that attracts rats not kiwi birds.
Place a rat trap near the kiwi's habitat so when the kiwi bird is going to it's habitat it wont step on the trap.

For saving the kiwi's

This is Zach & I's project. It is a rat trap to save the kiwi's from the rat's but we are also saving the rats so they don't die because no one wants a dead smelly rat. This is to help the kiwi's population.
This is how it works

    Rat Trap
I recommend if you just want to trap the rat jut stab some holes.If you want to kill the rat then just don't stab the holes unless this video says how much.
