tropical rainforest - interationship of carbon and water cycel Flashcards
rain that forms over the intact tropical rainforest may fall over what ?
fall over deforested land due to wind
if rain fall overs deforested land what may this cause?
erosion - soil and ash flowing into rivers, increasing carbon contnet of rivers
what does the water leaves the rainfrorest cycle as?
an output through streamflow
why does water leave the rainforest cycle through streamflow?
reduced intersection and increased surface runoff
why is there a reduced rainfall in the the intact forest?
there is less evapotranspiration in the deforested areas -> drought periods and the intact rainforest deteriorate
what does deforestation on peatlands and digging of drainage channels do?
reduce water storage
the organic peat matter is no longer preserved where?
underwater
what does the peat matter do bc of deforestation and drainage channels?
decomposes quickly - releasesing CO2 into the atmosphere
what speeds up decomposition in peatlands?
weathering and erosion increase
there is a greater wildfire risk form the…
hotter temperatures
what does help restore the natural environment - in peatland rainforests?
blocking drainage ditches
how does blocking drainage ditches help restore the natural environment?
increasing soil water storage and decreasing runoff
what can increasing soil water storage and decreasig runoff in peatland rainforest do?
raise the water table and decrease the flood risk
a managed forest is often less effective at what than a virgin forest?
sequestering CO2
