1

leaf litter

dead flora and fauna that decompose

2

leached

nutrients that are washed out of the soil

3

biodiversity

the number of different plant and animal species in an area

4

food webs

models that show the connection of plants and animals

5

direct threats

human caused deforestation eg. cutting down trees

6

indirect threats

nature caused deforestation eg. comes from pollution, global warming or disease

7

overgrazing

there are too many animals on the land

8

overcultivation

too many crops have been grown on the land

9

net primary productivity (NPP)

measure of how much new plant and animal growth, biomass, is added to a biome each year (measured in grams per square metre per year)

10

forest fragmentation

occurs when forests are cut down in a manner that leaves relatively small, isolated patches of forest fragments

11

intact forest

forest that has not been touched by human and not negatively impacted. It doesn't contain roads or other developments and the human activity occurring within it has low impact

12

wilderness

14

18

CITES (Convention on International Trades in Endangered Species(of wild fauna and flora)) advantages

many countries have signed up, protected species include a wide variety of species geographically and by type, successes such as reduced ivory trade

19

CITES (Convention on International Trades in Endangered Species(of wild fauna and flora)) disadvantages

global warming could undermine its success, protects species not ecosystems so deforestation isn't prevented, species have to be under-threat to be on the list so it could be too late
