Central Congo Basin
Transcript of Central Congo Basin
Older stems are brown and woody, young shoots green and succulent
Fibrous root system
Flowers are white or pale blue-ish purple Invasive Species Bibliography http://www.issg.org/database/species/ecology.asp?si=47&fr=1&sts=sss&lang=EN

Food Web C. odorata is a producer. Problem After farmers clear a section of the rainforest, C. odorata invades before pioneer trees can move in
They operate as creepers in the shade, climbing and smothering other plants
Can shade crocodile nesting sites, their roots making it harder for crocs to dig nests, and cooling nests that can be dug
Grows rapidly, slightly toxic, spreads quickly, re-grows if roots aren't eliminated
Fire spreads quickly Transport Native to south-eastern U.S., Mexico, tropical South America and the Caribbean
Most likely brought in to control weeds in fields and enrich soil in crop rotation Solution Prevention is the most effective method, as once C. odorata gets established it'd difficult to get rid of. Farmers have to weed very thoroughly.
To destroyed established populations, the above-ground portions of the plant must be completely destroyed, as well as the stumps and roots.
There are some chemical controls that can be put in place
There isn't very much more that can be done Characteristics: Major Ecoregions: Rainforest Freshwater River The plant is slightly toxic, nothing really eats it, but some people believe it has medicinal qualities Characteristics: Eco regions: Rainforest: Freshwater River dense evergreen forest
bordered by belts of savanna 2nd largest rain forest in the world Ecological Issue: The Congo Rainforest Endangered Keystone Species Eastern Lowland Gorilla AKA Gorilla beringei graueri
adult males weighing up to 220 kg (484 lb)
females weighing about 80 kg (176 lb).
Long arms Introduction Eastern Lowland Gorillas eat mainly fruit and other herbaceous materials
Nothing eats it
A gorilla is at the top of the food chain and is a primary consumer in a food web
bushmeat devastation Role Around two-thirds is found in the Democratic Republic of Congo (DRC) Gabon, Cameroon, Equatorial Guinea 2nd largest rainforest, Amazon is the biggest. Endangered
Mining Endangered Status One of UN World parks Heritage Sites (meaning they have special significance to the world). The Congo River, is the second largest river in the world 17,000 eastern lowland gorillas in the mid-1990s
Estimated Decline since then Population logging and expansion of farming endangered forest Monitoring

changes to ecosystems and the climate by altering local rainfall and other parts of the water cycle.
Fauna: change in climate could effect species. Too hot, too cold
Flora: risk of desertification Causes logging
cutting down valuable trees for easy profit. Solution nothing being done
implementation of forestry not strongly enforced
Other issues Poaching and bushmeat trade
Hunting of exotic animals for their meat.
Sold for profit. Disease Ebola hemorrhagic fever
affects primates monkeys and humans
