As afore mentioned fires have the ability to quite easily
create chaos by even making the slightest changes. An interesting paper I discovered
evaluated phosphorous levels in the soil. They discovered in their study that
fires significantly increase phosphorous within the soils. It turns out that
phosphorous is a limiting compound in aquatic systems which means that it is
very influential in stream ecosystems. The tricky part is that we have no way
to measure these tiny amounts of phosphorous in streams yet the slightest
increase can cause complete ecosystem changes. There are studies that have
proven that minimal increases in phosphorous cause algal blooms. It was
previously believed that these blooms were spreading through boats and
fisherman’s gear. Later it was found that phosphorous is the culprit for these ecosystem
devastating blooms. Algal blooms are extremely hard to control especially since
we don’t have any tools that can measure the compound that is causing them. The
study found that within the loose dead soil and ash, phosphorous is increasing
after fires and is then either blown or washed off into streams. They also
studied how restoration efforts can help prevent this layer of ashy soil from
escaping and wreaking havoc. Overall they found that mixing the soil and then
planting seeds as soon as possible is the most effective way to help mitigate this
if it is done soon enough before heavy rains and strong winds carry the new
soil away.
